A Review: Plant-Based Proteins: Market Growth Opportunities for Agricultural Products

Mercy Bientri Yunindanova

Plant-based proteins have garnered significant global attention over the past few decades. The demand for plant-based proteins has increased not only due to dietary trends such as vegetarianism or religious influences but also because of growing consumer concerns regarding health and the environment. Although it is known that plant-based proteins cannot entirely replace animal-based proteins, several studies have demonstrated the important role of plant-based proteins for the human body. This trend should be seen as an opportunity not only for stakeholders in the food sector but also in the agricultural sector. Knowledge about commodities with high protein content should be promoted. Additionally, the role of plant breeding is crucial in this regard. The increase in demand should not only be met by increasing quantity but also must be accompanied by quality to ensure market sustainability.

Reynaldi Laurenze 1), Nasaruddin 1), Reski Anugraeni Rahman 3) and Ainun Rahmawati N. 2)

Among the various plantation commodities in Indonesia, cocoa (Theobroma cacao L.) stands out because of its suitability for tropical regions and high market demand. However, cocoa production faces challenges such as fluctuating yields, one of which is influenced by the cherelle wilt factor that can reduce crop yields by up to 7-81% in cocoa plants. Paclobutrazol and KNO3 promote flower induction and support the formation and translocation of carbohydrates which can potentially mitigate cherelle wilt and improve cocoa production. This study aimed to investigate the effects of paclobutrazol and KNO3 on the reproductive growth of cocoa plants. The research was conducted in Bonto Macinna, Gantarang, Bulukumba, South Sulawesi from October 2020-March 2021. The study used a Randomized Complete Block Design (RCBD) with three replications for all treatments. The first factor is paclobutrazol concentration with four levels: 0 mL.L-1 (control), 3.75 mL.L-1, 7.5 mL.L-1, and 11.25 mL.L-1. The second factor is KNO3 concentration with three levels: 0 g.L-1 (control), 15 g.L-1, and 30 g.L-1. The results showed that there is no significant interaction between paclobutrazol and KNO3 on cocoa production. Meanwhile, paclobutrazol concentration of 11.23mL.L-1 provided significantly higher results in production components such as cocoa pods formed (70.78 pods), percentage of cherelle wilt (48.54%), harvested pods (15.00 pods), dry weight of 100 seeds (150.95 g), and yield (838.04 kg.ha-1) compared to the KNO3 treatment.

INDUCTION OF MAIZE RESISTANCE BY APPLICATION ARBUSCULAR MYCORRHYZA FUNGI Glomus etunicatum AGAINST DOWNY MILDEW (Peronosclerospora philippinensis)

Erwin Najamuddin*, Tutik Kuswinanti, Ade Rosmana, Hasbi, Aminah, Abdul Fattah, Rahman.

This research aims to determine the ability of inducing resistance of maize plants using glomus etunicatum mycorrhiza against downy mildew caused by P. philippinensis. The research was conducted at the Wire House, Laboratory of Plant Pests and Diseases of the Cereals Research Institute in Maros Regency. This study used a randomized block design consisting of 3 combinations of treatment factors. The first factor consisted of three levels, namely three maize varieties, including: Anoman/susceptible check (V1), JH29 (V2) and Pertiwi6/resistant check (V3), the second factor consisted of 2 levels, namely Inoculation (M1) and non-mycorrhizal inoculation (M0), the third factor consisted of 2 treatment levels namely inoculation (P1) and non-inoculation of pathogens (P0). A total of twelve treatment combinations were obtained. Each treatment consisted of 10 test plants so that there were 120 experimental units. The results showed that resistant varieties independently effectively suppressed downy mildew infection caused by the fungus P. philippinensis. The combination of AMF G. etunicatum and moderate varieties gave a better increase in plant resistance responses compared to the combination of AMF G. etunicatum and other varieties. The increase in plant resistance response occurred through increased resistance properties and accumulation of secondary metabolites (phenols and salicylic acid). As an alternative control technique that is environmentally friendly, a combination of varieties with AMF is an option for controlling downy mildew in maize.

Bambang lanang wood has been widely cultivated in South Sumatra Province as carpentry wood. This study analyzes the anatomical and boundary characteristics of bambang lanang wood juveniles planted at different planting distances. The materials used were three wooden disks from the bambang lanang trees from the Forest for Specific Purpose in South Sumatra with a thickness of 2 cm. The trees were planted with spacing of 3 m x 3 m, 4 m x 2,5 m, and 6 m x 3 m 12 years old. Anatomical characteristics were analyzed for macroscopic and microscopic, and at the same time, the determination of wood juvenile boundary was based on the radial variation of three parameters: microfibril angle, fibre length, and wood density. The result showed that the difference in planting distances did not affect the anatomical characteristics of bambang lanang wood. In general, the macroscopic characteristic of bambang lanang wood is yellowish brown, the wood texture is rather smooth to smooth, integrated fibre direction, the wood surface is rather shiny, and the tactile sensation is rather rough, while the microscopic characteristics are mixed pores, some are solitary, and multiple radials with 2-3 cells and no tylosis is found. Meanwhile, differences in planting distances also did not affect the boundaries of juvenile wood areas; that is, the boundaries of juveniles could not be determined.

Eko Fransisko1*, Loso Judijanto2, Abdul Rasyid3, Rahmat Joko Nugroho4, and Eddy Silamat5

The study of the potential for hybrid vigor in cayenne pepper plants is dissertation research in the context of realizing novelty research on the selection process for saline-tolerant cayenne pepper plants. The initial stage in this research is to determine the genetic relationship of the germplasm of cayenne pepper in terms of looking at kinship, the benefits of kinship and diversity in a germplasm and measuring the kinship value of the cayenne pepper it self. The next stage is to induce the salt content (salinity) in the cayenne pepper plants. Salinity is a condition where salt is dissolved in excessive amounts, which is bad for plant growth.Symptoms Plants experiencing salt stress generally do not show a response in the form of direct damage but suppressed growth and gradual changes; inhibits cell enlargement and division, protein production and addition of plant biomass.Selection for salinity tolerance in cayenne pepper was carried out with a series of conventional breeding activities startingby selecting superior individuals from a segregating population, followed by crossing between selected individuals, and continuing with selection on their offspring. The final stage in this research is to look at the inheritance of salinity tolerance traits in cayenne pepper plantsobtained through the assembly of varieties.Hybridization (crossing) in cayenne pepper is cross-pollination between parents of cayenne pepper plants with different genetic makeup. General combining ability and specific combining ability are important characteristics of cayenne pepper. Heterosis is an important characteristic of cayenne pepper for salinity tolerance. Heterosis or hybrid vigor is a situation where the vigor of a hybrid (F1), namely the result of a cross between 2 parents (P1 and P2) exceeds the vigor of the average of the two parents or the vigor of one of the best salinity tolerant parents.

Genetic diversity of tangerine (Citrus reticulata L.) at two altitudes based on morphological and molecular marker

N I Asmita 1*, I R Saleh 2, E Syam’un 3, Y G D Anggraheni 4

The distribution of tangerines can occur naturally or through cultivation in both lowland and highland areas. Ten characteristics were used to explain the diversity of tangerines: type of rootstock, leaf type, intensity of leaf green color, leaf lamina attachment, leaf lamina shape, leaf lamina margin, leaf apex, fruit shape, shape of fruit base, and shape of fruit apex. Genetic diversity and relationships among accessions were analyzed using random amplified polymorphic DNA. The biplot graph showed that the shape of the fruit base and fruit shape correlate positively with each other, as do the leaf apex, leaf lamina margin and leaf lamina shape. Meanwhile, the type of rootstock character correlates negatively with the other characters. PCA reduced the number of characters to two principal components, which account for a total variance of 80.95%. The characters that significantly contribute to this variance are the type of rootstock (63.60%) and the shape of the fruit base (17.35%). The characteristics based on morphological and molecular features form different similarity coefficients. Morphologically, the highest similarity coefficient is 0.59, while molecularly, the highest similarity coefficient is 1. This indicates that the similarity based on morphological characteristics is relatively limited, whereas molecular, the similarity is relatively extensive.

Sitti Inderiati1, Muh. Farid BDR2, Feranita2, Katriani Mantja2

Chrysanthemum is a commercially important ornamental plant, ranking as the second most popular cut flower in the global floriculture market. To induce variation through chromosome doubling in Chrysanthemum indicum cv. Pinka-Pinky, the four-week-old in vitro grown nodal segments were treated with various concentrations of Bio-catharanthine (0.05%, 0.1%, 0.15%, 0.2% w/v) for 8 h. Treated explants were cultured on Murashige and Skoog (MS) medium and the survived treated explants were sub-cultured to fresh MS medium for further growth and evaluation. The Ploidy level of plantlets was confirmed by flow cytometry and the induced tetraploids were cultured on multiple shoot proliferation and root induction media. Different Bio-catharanthine concentrations had different effect on survival percentage and did not significantly affect the number of shoots; however, the mutagen concentrations significantly influenced the number of leaves and roots as well as the speed of sprouting and rooting. The flow cytometry analysis showed that Induction of polyploidy (tetraploid) was achieved in all concentrations. These potential polyploids could be valuable for improving ornamental and horticultural value of Chrysanthemum.

DISEASE ASSESSMENT IN SORGHUM: SPREAD AND SYMPTOMS

Ernawati Djaya, Tutik Kuswinanti, Andi Nasruddin

A major challenge in sorghum cultivation is disease, which has a major impact on crop production and quality. This study aimed to identify and analyse the distribution and symptoms of common diseases in sorghum. The main diseases that often attack sorghum include leaf rust, mosaic, stem rot, anthracnose and leaf spot. The spread of these diseases can be influenced by various factors, such as environmental conditions, the presence of pathogens, and suboptimal cultivation practices. Disease symptoms in sorghum vary depending on the type of pathogen, for example leaf rust shows yellow to brown spots on the leaves, while mosaic causes an uneven pattern of light and dark green spots on the leaves. Stem rot often causes stem weakening leading to plant collapse, while anthracnose and leaf spot cause necrosis of leaves and other plant parts. A thorough understanding of the spread and symptoms of these diseases is important for developing effective control strategies. Thus, this research is expected to contribute significantly to efforts to improve the productivity and quality of sorghum crops through better disease management.

This study aims to determine the effect of boron (B) concentration as a priming agent on the germination performance of shallot seeds. The research was conducted at the Teaching Farm, Faculty of Agriculture, Hasanuddin University, under screen house conditions, in May 2024. Ten concentrations of boron (0, 20, 30, 40, 50, 60, 70, 80, 90, and 100 ppm) and one control treatment (0 ppm) were arranged in a randomized block design, with three replication. Significant effect of priming with B was only recorded in the parameters of germination percentage and germination speed index. The 100 ppm concentration exhibited the best effects on germination percentage (95.3%) and germination speed index (10.99). Increased B concentration showed a positive linear relationship with germination percentage (r2=0.96), germination speed index (r2=0.86), mean germination rate (r2=0.75), and germination speed coefficient (r2=0.75), and a negative linear relationship with mean germination time (r2=0.76) and T10 (r2=0.28). Therefore, the use of boron as a priming agent can be considered to improve the germination performance of shallot seeds.

The development of the plantation industry is essentially aimed at realizing the welfare of farmer communities, which is carried out by all stakeholders in the development of Southeast Sulawesi as the bearer of the mandate to realize the welfare of cocoa farmer communities. Cocoa (Theobroma cacao L.) is one of Indonesia's leading commodities, which is more frequently exported than sold in the domestic market. The world's largest cocoa producers are Côte d'Ivoire and Ghana, while Indonesia ranks second in cocoa production after Côte d'Ivoire. The development of the cocoa agro-industry in Southeast Sulawesi is fundamentally directed towards creating linkages between the plantation sector and other industrial sectors to drive the increase in added value and economic activity growth in a region. However, the development of the cocoa agro-industry in Southeast Sulawesi faces serious challenges, namely low cocoa productivity due to high infestations of cocoa pod borer (CPB), which results in poor quality cocoa beans, and the suboptimal development of products from upstream to downstream, causing the continuity of dry cocoa bean supply to be unmet. The objective of this study is to examine the development of the cocoa agro-industry sector by measuring the competitiveness of processed cocoa products from Southeast Sulawesi in the international market. The research methodology employs a qualitative study approach related to the development areas of the cocoa agro-industry in Southeast Sulawesi. The data used include primary data obtained through field observations and interviews, and secondary data obtained through literature reviews relevant to the research focus. Data analysis uses an interactive analysis model consisting of three components: data presentation, data reduction, and drawing conclusions. This study involves 60 informants, including elements from the Plantation and Horticulture Office of Southeast Sulawesi Province, staff and extension workers, and village officials in the cocoa agro-industry area, heads of farmer groups, farmers, cocoa entrepreneurs, and cocoa industry practitioners. The study results on the planning area conditions become the main capital in development planning and serve as the basis for determining the strategy for developing the cocoa agro-industry in Southeast Sulawesi. Comprehensive planning for the development of the cocoa agro-industry is directed towards three development phases: short-term, medium-term, and long-term phases.The basic concept in the strategy for developing the cocoa agro-industry area aims to direct cocoa farmers to independently implement cocoa agro-industry practices. The Southeast Sulawesi Provincial Government has endeavored to involve various stakeholders, including farmer groups, practitioners, and academics, although these efforts have not encompassed all involved stakeholders, especially relevant Regional Apparatus Organizations (OPD) and the private sector. Support for the transformation of cocoa plantation technology in Southeast Sulawesi includes economic potential, media involvement, and the adequate role of higher education institutions in Southeast Sulawesi. Meanwhile, government regulations support the application of cocoa processing technology transformation and address technical issues encountered in the field. Other challenges include human resource issues in changing farmers' conventional mindsets and administrative constraints such as the lack of technical planning documents, weak coordination with relevant parties, and insufficient budget support for the technical implementation team in the development activities of the cocoa agro-industry area in Southeast Sulawesi.

Financial Feasibility Analysis, Profitability Index, and Gross Margin: Study of Cocoa Farming in North Luwu Regency, Indonesia.

Andi Iva Mundiyah, Rahmawaty Andi Nadja, Muslim Salam, Andi Nixia Tenriawaru

The objective of this study was to examine the financial viability, profitability ratio, and gross margin of smallholder cocoa farming in North Luwu Regency. North Luwu Regency is home to one of Indonesia's largest cocoa-producing regions, situated within the South Sulawesi Province. In this study, the sample was 137 randomly selected cocoa farmers. The data used in this study was obtained from a structured interview process using a pre-made questionnaire. In order to achieve the objectives of this study, a quantitative approach was used, with data analysis methods including cost analysis, revenue, total income, net profit, rate of return, and profitability index. The research results show that the cocoa production costs incurred by farmers are IDR 8,623,866/ha. Moreover, the average cocoa production was 1,384 kg/ha with a selling price of IDR 36,349/kg, resulting in a gross margin of IDR41,962,240/ha and a net income of IDR33,338,374/ha. We may conclude that the rate of return on cocoa production was approximately 4.89 percent. The result of the calculation for the cocoa farm profitability index was 0.83. This figure of 0.83 suggests that for every 1.00 rupiah spent by farmers in the production process, there was the potential for a profit of 0.83 rupiah. It would seem, then, that cocoa farming in the research location was financially profitable, which would suggest that it is worth continuing to develop.

Suarni1,*, Anna Sulistyaningrum2, Muhammad Aqil1

Waffles are a versatile bakery product that appeals to a wide range of consumers, including children, teenagers, pregnant women, and adults. In addition, the products are affordable and accessible across different income levels. In the effort to develop innovative functional foods, one strategy is to substitute wheat flour with sorghum flour, which is high in dietary fiber, iron, and antioxidant. This study investigates the impact of incorporating modified sorghum flour, prepared through pre-gelatinization, on the physical attributes, nutritional content, and antioxidant activity of waffle products. Additionally, the research aims to identify the most favorable concentration of modified sorghum flour substitution for wheat flour based on panelist preferences. A completely randomized design was applied, featuring variations in the substitution levels of wheat flour with two types of sorghum flour, Numbu and Soper6. Findings revealed that the most successful waffle formulation combined wheat flour and modified Numbu sorghum flour at a ratio of 60% sorghum to 40% wheat (SNT 60%: TR 40%), which closely mimicked the characteristics of 100% wheat flour waffles and received high sensory ratings for color, texture, aroma, and taste. Moreover, this formulation demonstrated an antioxidant activity of 12.42%. The development of modified sorghum flour using the pre-gelatinization method, alongside the production of these waffles, introduces new opportunities for local entrepreneurs in the growing market for functional snacks.

Prevalence of Fusarium sp. Mycosis on Aphis gossypii (Hemiptera: Aphididae) infesting chili crops in South Sulawesi, Indonesia E Erwin, M Junaid, and A Nasruddin* Department of Plant Pest and Disease, Faculty of Agriculture, Hasanuddin University, Makassar, Indonesia 90245 Corresponding author’s email: andinasruddin@yahoo.com Abstract. Aphis gossypii (Hemiptera: Aphididae) is one of the major pests of chili plants in Indonesia. Our previous survey showed that the aphid was naturally infected by Fusarium sp. in several farmers’ fields in South Sulawesi, Indonesia. Therefore, the current study was conducted to determine the prevalence of the aphid mortality due to Fusarium natural infection in the field. A field experiment was established with three chili cultivar treatments: Pilar F1, Baja MC F1, and a local cultivar of Saludua, arranged in a complete randomized block design with 10 replications. No fungicide applications were employed during the course of the study. Study results showed that no significant differences among the cultivars in the number of aphids per plant and the rates of the nymphal and adult mortality. However, the entomopathogen was highly virulent to A. gossypii with overall mortality rates against nymphs and adults were 49.4% and 58.1%, respectively. This suggested that Fusarium sp. has a potential to be developed as a bioinsecticide against the aphid.

The survey was conducted in five chili planting centers in the province, namely: Regencies of Enrekang, Maros, Makassar, Gowa, and Takalar. In each regency, three planting locations of chili growers were observed, at each location five plants PepYLCIV-infected plants and five healthy plants were selected randomly. Three leaves were randomly selected from each sample plant to determine the population of B. tabaci and the severity of PepYLCIV attack. To determine the incidence of the disease, one hundred plants were observed in each location. The incidence was calculated based on the percentage of sample plants showing symptoms of PepYLCIV disease. In addition, the population of B. tabaci on other plants, namely eggplant, cassava, and African leaves were determined by following the procedures described previously. The results showed that the PepYLCIV had spread widely throughout the survey locations with varying levels of incidence and severity of the disease. The results showed that the highest incidence and severity of PepYLCIV were found in Takalar Regency, which were 40.2% and 54% respectively. The lowest incidence and severity of the disease were found in Enrekang Regency, which were 10.3% and 6.2% respectively. Meanwhile, the incidence and severity of the disease were moderate in Maros Regency, Makassar, and Gowa Regencies. The population of B. tabaci tended to be higher in diseased plants compared to healthy plants. Meanwhile, in other hosts, namely eggplant, cassava and African leaf plants, a fairly high population of B. tabaci was found but not significantly different from the population in chili plants. To the best of our knowledge, the results of this study are the first report on the distribution, incidence, and severity of PepYLCIV in South Sulawesi.

Characteristics of bubbles in a venturi aerator type water culture system

Sitti Nur Faridah, Husnul Mubarak, Suhardi, Iqbal and Asyer Manganna.

The water culture irrigation system uses a growing medium in the form of water that is quite deep and the water does not flow. This media character has the consequence of limited oxygen availability in the root area due to poor circulation. Plant roots submerged in nutrient solutions rot easily, due to lack of oxygen. Using the right aeration system can meet the need for dissolved oxygen for plant growth. Microbubble technology can increase the oxygen content in the water culture system nutrient solution. This research uses a ventury earator to produce microbubbles with 3 pressure differences, namely 70 KPa, 75 KPa and 80 KPa respectively. Bubble characteristics were analyzed using the image processing method with the Matlab application. The research results show that differences in water flow pressure will produce differences in the size and reach of bubbles from the ventury aerator. A flow pressure of 80 KPa produces a bubble size of 14.07 – 44.95 m with an average size of 21.12 m and a bubble reach of 33 cm. The pressure of 75 KPa is 14.35 – 65.06 m with an average of 27.26 m and a reach of 31 cm. Pressure of 70 KPa is at a distance of 15.75 – 97.80 m with an average of 33.83 m and a range of 26 cm. The smaller the bubble size indicates the higher the oxygen content in the nutrient solution.

Exploration of Fermentation Methods in Enhancing Bioactive Compounds in Green Plants: a Review

Naurah Nazifah Sarmadi and Arfina Sukmawati Arifin

Green plants are recognized for their potent free radical inhibition, attributed to their bioactive compounds, such as phenolics, which neutralize free radicals by donating hydrogen atoms or electrons. Though present in small quantities, these bioactive compounds offer significant health benefits, including in managing immune disorders, cardiovascular diseases, diabetes, and neurodegenerative conditions. Previous methods to enhance these compounds, such as physical processing, microencapsulation, genetic engineering, and solvent extraction, have limitations. Fermentation has emerged as an eco-friendly and effective alternative for increasing bioactive compound levels in green plants. This process involves the hydrolysis of phenolic fucosides by β-glucosidase, releasing free phenolics and enhancing bioactivity. This review seeks to identify optimal fermentation strategies across different green plant species, focusing on the specific plants and microorganisms used.

Abstract. Soybean agribusiness development is a key issue in Central Sulawesi Province. This research is aimed at identifying the condition of the soybean agrobusiness system in Parigi Moutong Regency, which is one of the centers of soybean production in the region. A total of 27 informants with a total of 5 stakeholders and 22 soybean farmers were interviewed. Data were collected in a structured manner through in-depth interviews using interview guidelines. Based on the data obtained, a strategy for soybean farming development was developed using SWOT analysis. The results show that (1) the upstream subsystem has not yet functioned, where the actors of the procurement of production facilities are still carried out individually which causes a lack of production inputs, namely, the problem of soybean seeds. (2) In the farming subsystem, soybean cultivation has provided benefits for farmers. (3) The processing industry has an important role in the soybean agricultural subsystem in the district. It is expected that the local government of the district will assist soybean farmers in implementing the strategic mapping that has been formulated by making adjustments to soybean agricultural conditions.

Iqbal, Abdul Azis, Muhammad Tahir Sapsal, Husnul Mubarak, Abdul Waris, Daniel Useng, Mursalim, Gemala Hardinasinta, Febriana Intan P H, Muhammad Rizal

South Sulawesi (Sulsel) is one of the coffee production centers with a planting area of 71,473 hectares in 2020. Based on the South Sulawesi Disbun, the average annual production of South Sulawesi coffee reaches 34,059 tons (Dirjenbun, 2021)1 The problems faced in cultivating coffee in Bantaeng district include that because 96% of this plant is cultivated by the people, the cultivation techniques are not in accordance with the recommendations for good agricultural practice (GAP); low plant productivity; weak farmer institutions; The value added received by farmers is low because some of it is exported in the form of coffee beans, limited capital and low mastery of post-harvest technology resulting in low coffee quality. The main obstacles in production are a lack of knowledge regarding good plant procedures and cultivation, insufficient extension workers, and difficulties in accessing information regarding good coffee cultivation. The rapid development of communication technology today has an impact on the number of communication media that can be used to disseminate agricultural information. One of the communication media that can be used is cyber communication or internet media. Information sharing in the context of disseminating good plant information is also an obstacle in improving farmer performance considering the conditions in areas that are quite difficult to reach. In the midst of the many digital platforms that can be used, farmers are quite minimal in their use of this technology, so the learning, consultation and information sharing processes are still not optimal. This research gave birth to a digital farming system model (Digital Farming) that can be used by various stakeholders to increase farmers' knowledge so that they can increase productivity and quality of coffee in Bantaeng district.

Effects of Germination and Spontaneous Fermentation on the Physical Properties of Soybean, Kidney Bean, and Mung Bean Flours

D G Nadhifa 1, M Mahendradatta 2,3*, F Bastian 2,3

Soybeans, kidney beans, and mung beans are commonly consumed commodities in Indonesia. They are well-known for their high nutritional value but also include antinutrients that prevent the body from absorbing nutrients. Germination and fermentation are cost-effective methods of reducing antinutrients in beans, which also affect the physical properties of the resulting bean flour. The current study investigated the effects of germination and spontaneous fermentation of soybean, kidney bean, and mung bean on the physical properties of their flours, specifically regarding color intensity, bulk density, water-holding capacity, and oil-holding capacity. The research findings indicate that fermentation and germination reduced the brightness and bulk density of soybean and mung bean flours but increased them in kidney bean flour. While fermentation and germination processes inclined the water-holding capacity of all three types of bean flours, they declined the oil-holding capacity of soybean and kidney bean flours. Furthermore, fermentation resulted in higher brightness and water-holding capacity of bean flours compared to germination. However, germination tended to produce higher bean flour bulk density than fermentation, and insignificant differences were exhibited between the two treatments in the oil-holding capacity of the bean flour.

Effect of Air Velocity and Grain Mass on Drying Rate of Ciliwung Variety Grain Using Fluidized Bed Dryer Title

Nurasia

One of the determinants of rice quality in Indonesia is the problem with the grain drying process. So far. farmers have only used traditional methods by placing them directly in the sun. which is still relatively low. Proper drying requires uniform heat to slow grain deterioration after harvest, grain must be dried to a level that allows safe storage of moisture content 13-14%. Therefore. a good drying method is needed to produce grain drying with good moisture content quality. The purpose of this study was to determine the effect of air velocity and grain mass on drying rate using a temperature of 50 oC using a fluidized bed dryer. This research method uses speed variations of 2.0 m/s. 2.5 m/s, da 3.0 m/s with a sample weight of 150 g. 200 g and 250 g. using a temperature of 50 ℃. The research parameters included moisture content, drying rate, cracked seeds. This drying process shows that the change in sample weight is affected by the air speed used. The greater the air velocity used. the greater the decrease in the resulting sample weight. The highest drying rate occurs at the beginning of drying while with increasing time and the drier the remaining material is water bound to the material cells so that the decrease in water content becomes smaller and finally reaches the desired moisture content. The speed of the air and the mass being dried affect the drying rate and there is an interaction between the two factors. Air speed affects the craking of rice grains.

Production of maltose syrup from sago starch uses the enzymes β-amylase and pullulanase

Nurfadillah1*, A Laga1, F Bastian1.2

Sago is one of the carbohydrate source plants that is often found in various regions in Indonesia, especially eastern Indonesia. However, the use of sago in Indonesia is still not optimal. One alternative use is to enzymatically modify starch to produce maltose syrup using β-amylase and pullulanase to hydrolyze the glycosidic bonds α-1,4 and α-1,6 in sago starch. The enzyme β-amylase (EC 3.2.1.2) catalyzes the hydrolysis reaction of glycosidic bonds α-1,4 and pullulanase (EC 3.2.1.41) catalyzes the hydrolysis reaction of glycosidic bonds α-1,6. Maltose syrup can be an alternative sweetener to reduce the amount of sugar imports in Indonesia. The optimal conditions in the process must be known to obtain pure maltosa syrup. The purpose of this study is to determine the concentration of the substrate, the reaction time of saccharification and the total maltose produced. Analysis of raw materials on starch content, amylose content, amylopectin and moisture content. The findings of the study show that the starch content is 89.46%, amylose is 14%, amylopectin is 85% and the moisture content is 12.4%, the starch content of sago has a high enough purity so that it has the potential to be used as a raw material in making maltose syrup.

Climate change has caused extreme heat that significantly impacts the growth of cacao trees. This study examines the effect of organic mulch and shade of the hedgerow system on the growth of young cacao trees and soil microclimate as an adaptation to the high temperatures. Hedgerow systems potentially produce biomass that is used as organic mulch on the cacao sub-canopy using the treatment of coconut leaves (B1), banana leaves (B2), livestock feed residue (B3), and without mulch (B0). Measurements of soil temperature, moisture, and percentage of shades were carried out 14 days after treatment at three observation times (8-9 a.m., 1-2 p.m., and 4-5 p.m.). Meanwhile plant growth for height, diameter, and canopy) was measured four months after treatment. The result of observation indicated that it significantly reduced temperature and increased soil moisture mainly at 8-9 a.m.. In addition the applications of coconut leaf mulch provided the best results on canopy growth, plant height, and stem diameter. The interaction between shade and banana leaf mulch at 4-5 p.m. resulted in the highest shade percentage, supporting optimal soil microclimate. This study emphasizes the importance of managing agricultural systems and bioresource to overcome the impacts of extreme heat due to climate change.

Lembah Palu shallot is one of Central Sulawesi's leading commodities used as raw material for the fried onion industry and has become a local brand of Palu. This variety is included in the Wakegi onion group, a unique onion plant resulting from a cross between the elder's Allium cepa and Allium fistulosum. This crossbreeding process, likely an alloploidy process, results in an onion that does not produce seeds, indicating that the plant is triploid. Efforts can be made to improve the character through polyploidization using colchicine. This research aims to study the interaction between the length of soaking and the use of colchicine on the process of polyploidization of Lembah Palu shallots and to analyze and evaluate the effect of colchicine concentration and length of soaking on the process of polyploidization of Lembah Palu shallots. The research was conducted in the greenhouse of the Faculty of Agriculture, Hasanuddin University, Makassar, which began in December 2023 - April 2024. The first factor is the concentration of colchicine consisting of 5 levels of treatment namely 0.0, 0.025, 0.05, 0.075, and 0.1% and the second factor is the length of soaking consisting of 3 levels of soaking treatment namely 3, 6 and 9 hours based on a randomized block design (RBD) pattern arranged factorially with two treatment factors. The results showed that the concentration of 0.1% colchicine showed the best results on sprouting time (6.84 HST), leaf thickness (1.30 mm), and pseudo-stem diameter (2.43 mm).

Ahmad Firman Ashari1,*, Risma Neswati2, Mahyuddin3, Samsu Arif4

The expansion of Makassar City into surrounding urban areas within the Mamminasata region has led to the conversion of rice fields into settlements. This fragmentation of rice fields into smaller, separate areas can reduce food productivity, cause environmental degradation, and threaten biodiversity. This study aims to analyze the changes in rice field land use and measure the fragmentation index in the Mamminasata urban area from 2016 to 2024. Methods include satellite imagery processing for land use classification, map overlay for identifying rice field changes, and converting raster data to vectors using the ‘reduceToVectors’ function in Google Earth Engine to calculate fragmentation metrics. The findings reveal a decrease of 1,015 hectares in rice field area from 2016 to 2024. This change led to an increase in rice field fragments from 5,245 to 5,305, a reduction in average fragment size from 475,785 m² to 470,410 m², relatively stable standard deviation values (23,532 in 2016 and 23,557 in 2024), and a slight increase in the coefficient of variation from 49.46 to 50.08 over the same period.

The changing of soil quality and microbial community with additional biomass on intensive and non-intensive cultivation lands

M R S Moata, W Boboy, S Vertygo

Dryland management is complicated by various challenges, water scarcity, lack of soil organic matter, slopping, and stones soil due to climate change. Local practicing farming system slash and burn is a common method for land clearing. Therefore, this study aims to determine the effect of biomass addition to different soils on soil quality. Soils were collected from intensive-IC and non-intensive cultivation- NIC lands (slash-burn system) at Netpala village Timor Tengah Selatan, NTT- Indonesia. Each soil was treated with five treatments (control, 20% addition of rice husk charcoal-RHC, wood charcoal-WC, rice husk-RH, and wood leaf-WL) and three replicates for each treatment. The samples were incubated for 30 days, composited, and analyzed for the chemical properties of soil and microbial P community. After biomass addition, all chemical compounds (Ntot, P2O5, K2O, Corg, pH, and total microbial P) were increased for both lands, but higher at NIC’soils. However, IC sois are more responsive when adding biomass over control. Each treatment provides different response, the highest response of IC: NIC respectively are N (67% WL: 26% WL), P2O5 (125% RHC: 107% WC), K2O (64% WL: 25% WL), Corg (140% WC: 115% WC), Mic-P (160% WL: 146% RHC), and pH (5,8 to 6 pH: 6,1 to 7,4 pH). The IC has affected to lower quality of soil (control) but an additional 20% of biomass has improved the quality of soil even though not as high NIC soils were only used once a year (rainy season after land burning). Maintenance of climate adaptive and sustainable productivity of dryland requires additional biomass of over 20% for IC land and up to 20% for NIC.

Quality and physicochemical properties of combined rice from germination and pre-cooking process

Nur Rina Abdullah

Precooked sprouted rice appears to be an alternative for improving products and has been studied for its different nutrients and bioactives. Knowledge of the characteristics of pre-germinated rice used as a functional food ingredient is very important. This is because the germination process can affect the characteristics of the resulting pre-germinated cracked rice. The rice germination process begins with soaking the rice seeds in water for a certain period of time, usually between 12 to 24 hours. The purpose of this soaking is to accelerate the biochemical changes necessary to initiate seed growth. During soaking, the rice seeds absorb water, which causes swelling of the seeds. This process triggers various biochemical reactions within the seeds, including increased activity of enzymes such as amylase. Meanwhile, the pre-cooking process causes metabolic changes in the rice. Steaming results in gelatinization, where starch crystals are broken down and expand into a viscous gel, which then retrogrades during drying, re-forming more stable starch crystals. This change not only increases grain hardness but also alters the physical and chemical characteristics of the rice. Precooked rice has physical characteristics such as harder and less breakable grains, and a more yellow color. This journal discusses the cooking and textural properties of brown rice that has undergone the germination process (soaking and germination). The method used in the literature review is in the form of a research data base and journal references regarding the quality and physicochemical properties of combined rice resulting from the germination and pre-cooking process.

Winda Nawfetrias1* Delvi Maretta1 Irna Surya Bidara1 Cri Wahyuni Brahmi Yanti3 Yomi Guno2

Plants produce secondary metabolites for survival in extreme environments that are valued for medicinal purposes. These metabolites can be enhanced using abiotic or biotic elicitors, such as endophytic fungal, which act as elicitors in various medicinal plants. Phyllanthus niruri, or meniran, is an Indonesian medicinal plant with various bioactive compounds and rich pharmacological activity. Colletotrichum gloeosporioides is an endophyte fungus of P. niruri and known as a pathogenic fungus that causes anthracnose in horticultural plants. This study proposes that the elicitation of C. gloeosporioides through seed treatment induces bioactive compounds related to plant defense, which are beneficial for human health. The present study was carried out during 2022 and 2023 at an experimental greenhouse of National Research and Innovation Agency, Banten, Indonesia. We treated P. niruri’s seed with C. gloeosporioides inoculum and analyzed methanolic extract of P. niruri based on gas chromatography mass spectrophotometry (GCMS). The study identified 43 compounds and 46 compounds, respectively, in control and elicitation treatment. We detected 26 bioactive compounds that are identified in both treatments, control and elicitation treatments. Octacosane,2-methyl-; Octacosane; Nonacosane, 2-methyl-; Isoshyobunone; Heneicosane; Docosane; 9-Octadecenoic acid; 9-Octodecenal (Z); 1-Nonadecende; 1-cis-Vaccenoylglycerol; and 13-Octadecenal tend to increase in elicitation treatment compared to control. These compounds are associated with the cuticular component of plants and have important roles as anti-fungi, anti-microbial, and stress response. The research showed that 23 specific compounds were detected only in elicitation treatments. These compounds are detected to have medicinal potency as anti-inflammatory, antioxidant, anti-cholesterol, antibacterial, antifungal, anti-cancer, and immunomodulator.

We studied Phyllanthus niruri L. (meniran) in three different environments with varying microclimate especially temperatures, relative humidity, and photosynthetic photon flux density (PPFD) to determine the optimal environment for P. niruri growth. The present study was conducted from March to May 2024 at National Research and Innovation Agency, Banten, Indonesia's experimental greenhouse, screen house, and growth room. Microclimate parameters were observed thrice daily at 8 am, 12 pm, and 3 pm during the research. The three environments significantly differ in microclimate. The average temperatures, relative humidity, and PPFD of greenhouse are 34.98±3.77 oC, 63.27±6.82%, and 405.27±43.70 µmol m-2 S-1, screenhouse are 32.48±0.49 oC, 71.39±1.75%, 290.17±30.57 µmol m-2 S-1, growth room is 21.64±0.46 oC, 92.92±0.93%, 6.82±12.71 µmol m-2 S-1. Different microclimates induce significant soil temperature and moisture. The soil temperatures of greenhouse, screen house, and growth room are 29.11±0.07 oC, 28.93±0.15 oC, and 28 oC. The soil moisture of greenhouse, screen house, and growth room are 44.71±14.14%, 71.43±8.66%, and 100%, respectively. All treatments were repeated nine times. After six weeks, growth parameters such as shoot length, root length, shoot fresh weight, root fresh weight, shoot dry weight, root dry weight, and physiology response such as chlorophyll content index, H2O2 level, and proline level were observed. The result showed that all parameters except root fresh weight and proline level showed significant differences between microclimate treatments. The greenhouse environment showed significantly different shoot lengths, root lengths, shoot dry weight, and root dry weight higher than screen house and growth chamber. However, the greenhouse environment showed higher level of H2O2 that indicates temperature, relative humidity, PPFD respectively 34.98±3.77 oC, 63.27±6.82%, and 405.27±43.70 µmol m-2 S-1 have the potency to influence the physiological response of P. niruri while maintaining biomass accumulation.

Chilli is one of the most important commodities in Indonesia and requires high number of inputs. Using inputs such as fertilizer that suitable with plant's requirement will induce efficiency. This experiment aims to determine the efficient fertilizer concentration in cayenne cultivation. There are two varieties of cayenne (Bara, Genie) and five concentrations of AB mix fertilizer (0, 350, 700, 1050, 1400 ppm). Observations were made on growth (plant height, dichotomous height, number of leaves, stem diameter, SPAD, plant fresh and dry weight) and yield (number of flowers, number of fruits, fruit fresh and dry weight). Results showed that vegetative growth revealed significant response to fertilizer in plant height, number of flowers, SPAD and stem diameter. Plant height and SPAD were higher in Bara while number of flowers and stem diameter were higher in Genie. There was no significant difference in yield to various fertilizer concentrations, but trend showed the increase of these parameters at 1400 ppm. Genie variety has a higher fresh fruit weight than Bara, presumably because of its good tolerance to drought. It is recommended that further fertilizer concentration research be carried out at a higher dose than 1400 ppm to elaborate plant response in higher nutrient concentrations.

Indah Triana1, Andi Nilawati Usman1, Risfah Yulianty2, Sharvianty Arifuddin3, Andi Ariyandy4

Virgin Coconut Oil (VCO) production in Indonesia has great potential, given the abundant availability of raw materials and the health benefits offered. However, to achieve sustainability in this industry, it is imperative to pay attention to product quality and innovate in the production process. These two areas, along with strategies to overcome existing challenges, are the key to the future of VCO production. With these measures, VCO can continue to be Indonesia's flagship product in the global market. This literature review aims to determine the various methods of VCO production and the health benefits of VCO. The method used is a literature study, based on several databases of search results with the keywords selected in the search are “production” “VCO”, and “health benefits”, filtered based on the title of full text availability. In conclusion, the production of VCO has many methods including acidification, centrifugation, heating, fermentation, cooling, salting and salting methods. The cooling method is one of the best ways to produce high-quality VCO. Although the process is slower and may produce less oil than the fermentation method, the quality of the oil produced is superior. The lauric acid contained in VCO will be converted into monolaurin, a monoglyceride compound that has antibiotic properties including antiviral, antibacterial, antiprotozoa, so that it can increase the human body's resistance to disease and accelerate the healing process.

Optimizing sugar-free hard candy formulations: physicochemical, sensory and stability analysis of regular and chili-flavored variants

Filiana Santoso, Sulie Asri, Abdullah Muzi Marpaung

This research aimed to identify optimal formulations for sugar-free hard candy, focusing on base and chili-flavored variations. Among 16 base formulas tested, the formulation containing 90% isomalt, 4.5% erythritol, and 5.5% sorbitol was identified as the most favorable, based on sensory assessment by 50 untrained panelists. This specific combination resulted in translucent, light-colored candies, with variations in texture attributed to different ratios of isomalt, sorbitol, and erythritol. High isomalt content produced a firmer, less sticky candy with a yellowish hue and low moisture, while high erythritol content yielded a softer, transparent candy with low moisture and high soluble solid content. Formulas with high sorbitol content produced a softer, stickier texture due to its hygroscopic nature. For the chili-flavored variation, nine formulas with varying amounts of citric acid and chili powder were evaluated. The formula containing 0.5 grams of chili powder and 0.9% citric acid achieved the highest hedonic score of 5.95 from 43 respondents, indicating moderate approval. Stability tests conducted at 25°C and 40°C over 8 weeks revealed no significant changes in moisture content and pH; however, noticeable color alterations were observed after 14 days, likely due to exposure to light and air. The findings provide valuable insights into the impact of specific ingredients on the sensory attributes and stability of sugar-free hard candies, laying a foundation for future research and potential commercialization.

Fermentation Kinetics of Xanthomonas campestris Using Sago Substrate During Xanthan Gum Production

Sri Wahyuni, Amran Laga, Andi Dirpan

Sago starch is a potential alternative substrate for xanthan gum production because it consists of long chain glucose. This study aims to analyze the acquisition of xanthan gum with sago hydrolysate substrate. This research was conducted in two stages. The first stage was differentiated based on the type of sago hydrolysate (maltodextrin, dextrose) and fermentation time (0-72 hours). The best fermentation time from the first stage was then used in the second stage, which was differentiated by substrate type (pure dextrose, sago dextrose, sago maltodextrin) and substrate concentration (2%, 4%, 6%, 8%). The process of xanthan gum formation by Xanthomonas campestris begins with the entry of the substrate into the cell through phosphorylation reactions and is used in the process of catabolism and anabolism for the formation of polysaccharides. It is expected that the results of this study can show that sago hydrolysate substrate can produce xanthan gum with optimal yield, and provide a new alternative in the use of local resources for the production of high-value biopolymers.

A. Dinda Namirah Sarilla, Muhammad Junaid, Baharuddin Patandjengi*

Plant disease caused by Ralstonia syzygii subsp. celebesensis (Rsc) pose a serious threat to banana production in Indonesia and Malaysia. Banana blood disease is a systemic disease that live in xylem cells causing less-symptoms in initial attack. Early and accurate detection is crucial to reduce the impact of this disease on crop yields. The development of rapid detection methods for Ralstonia syzygii subsp. celebesensis, including Lateral Flow Immunoassay (LFIA), PCR, and LAMP, represents a significant advance in plant disease diagnosis. Disease testing with real-time PCR is capable of detecting Rsc isolates as well as symptomatic plant part samples as evidenced by meeting validation parameters. PCR has various advantages, including high sensitivity and specificity, multiplexing capabilities, quantitative analysis, flexibility in primer design, and sequencing capability. Both immunoassays and LAMP offer substantial benefits in terms of speed, convenience of use, and cost-effectiveness. However, immunoassays may lack the sensitivity of PCR, while LAMP requires more complex primer design and less suitable for sequencing applications. These methods enable timely and accurate detection for effective disease management strategies. This review demonstrates the potential application of rapid banana blood disease detection technologies. It will be applied to produce Rsc-free banana seedling trough tissue culture.

Aminah, Andi Nasruddin, Baharuddin Patandjengi

Banana Bunchy Top Disease (BBTD) caused by the Banana Bunchy Top Virus (BBTV) is a major threat to global banana production, with potential yield losses of up to 100%. The systemic transmission of BBTV from infected mother plants to their suckers, often asymptomatic or symptomless, complicates disease management. Consequently, prevention, particularly through the use of virus-free banana seedlings, is crucial, highlighting the need for robust early detection methods. Molecular detection techniques are essential for effective management of BBTD, offering greater sensitivity and specificity than conventional methods. Key techniques include Polymerase Chain Reaction (PCR), Real-Time PCR (qPCR), Loop-Mediated Isothermal Amplification (LAMP), and Recombinase Polymerase Amplification (RPA). PCR and qPCR are highly accurate but require costly equipment and longer processing times. In contrast, LAMP and RPA offer rapid, portable alternatives, making them more suitable for field applications. This review synthesizes recent advancements in molecular detection technologies, assessing their effectiveness and exploring the challenges and future prospects in BBTV control.

Gaizka Azzahra, B Patandjengi, A Nasruddin, Nurmujahidin N

Bacterial panicle blight, a disease that is becoming increasingly significant in the world's rice supply, is caused by Burkholderia glumae. Bacterial panicle blight is thought to be caused by seed-borne; however, its disease cycle is not fully understood. Despite its significant economic impact, no rice types are entirely resistant to the disease, nor are there any efficient control methods for bacterial panicle blight. However, it is advised that seed quality be improved by using a biopriming technique, utilizing antagonistic bacteria to lower the occurrence of bacterial panicle blight. This study aimed to obtain a method of treating rice seeds with Pseudomonas fluorescens that can suppress B. glumae bacteria during the vegetative period. The experimental setup was a Completely Randomized Design (CRD), including five treatments and four replications. The results showed that the population of P. fluorescens bacteria at PF8+BG8 treatment isolated from the roots of rice plants was able to maintain bacterial conditions with a bacterial population of 16.4×104 CFU mL-1 and suppress the growth of B.glumae by 14%. The PF8+BG8 treatment isolated from rice stems was able to maintain the bacteria with a bacterial population of 12.3×104 CFU mL-1 and suppress the growth of B. glumae by 22%.

F K Sahlan1, T Kuswinanti1 and B Patandjengi1*

Stewart's wilt disease caused by Pantoea stewartii subsp stewartii (Pss) is devastating maize disease that cause yield losses ranging from 40-100%. This seed-borne pathogen is primarily infected by vectors. As a maize producing country, the spread of Pss in Indonesia is still limited in some provinces, such as West Sumatra, Bali, West Java and East Java. However, there have been no reports of Stewart's disease in South Sulawesi. Therefore, this study is necessary to determine the occurrence of the disease and identify based on morphological and physiological characteristics. More than 40 yellow-pigmented isolates with entire and circular colonies were found. All isolates were gram-negative, rod-shaped, facultatively anaerobic, catalase positive but negative for oxidase and indole production, which are characteristic of Pss. Pathogenicity test was conducted using 1 mL of 10^8 CFU/mL of bacterial suspension. Each isolate was injected into healthy 14-day-old maize. The result showed that 5 isolates were able to infect maize and cause symptoms similar to Stewart's disease. Further research is needed to accurately identify the bacterial causal agent and determine the diversity of bacterial isolates based on biochemical and molecular analysis, as well as to determine maize lines and varieties resistant to Stewart’s wilt disease.

Fitrianti1,*, Tutik Kuswinanti2, Melina3 ,Jayadi4 ,Ratnawaty5

Cocoa pod husk is a waste product that can be converted into nutritious organic fertilizer, which improves soil structure and increases cocoa producers' income. Microorganisms can be a more efficient way to convert cocoa residue into organic fertilizer. Three isolates, Trichoderma harzianum, Trametes versicolor, Pleurotus ostreatus, and a bacterial formula MikrobatTM, were tested in vitro for their ability to degrade cocoa pod husk and prevent the growth of Lasiodiplodia theobromae. Three replications were performed to test various combinations of isolates and bacterial formulae. The results indicate that all isolates and the Mikrobat formula effectively break down cocoa pod husk waste. In the dual culture test, T. harzianum demonstrated the most inhibitory effect against L. theobromae on both potato dextrose agar and potato dextrose broth. Trichoderma harzianum's interactions and antagonistic mechanisms include antibiosis, competition for space and nutrients, mycoparasitism, and lysis, all of which have an inhibitory effect of 66.8%. Trametes versicolor's interaction type and antagonistic mechanism is mycoparasitism, which has an inhibitory effect of 40.3%. The Microbat formula features an antibiosis mechanism that inhibits growth by 19.74%.

Development of molecular early detection technique of Fusarium oxysporum f. sp. cubense on banana: a literature review

Rezki Meylansari1, A Nasruddin1, Baharuddin Patandjengi1

Fusarium oxysporum f. sp. cubense (Foc) is a soil-borne pathogen that invades the root system and causes blockage of xylem vessels, posing a significant threat to global banana production by causing Fusarium wilt disease. Detecting this plant pathogen early is essential for effective disease management. Traditional methods such as symptom visualization and microscopic observation have proven to be inaccurate. To address this case, molecular detection technologies have been developed to provide more accurate and sensitive methods for early detection. Several methods such as Polymerase Chain Reaction (PCR), Real-Time PCR (qPCR), Isolated isothermal PCR (iiPCR), and Loop Mediated Isothermal Amplification (LAMP) have been used. PCR and qPCR are highly accurate and sensitive but require optimization and validation. iiPCR enables rapid field detection and high sensitivity. LAMP offers rapid and portable detection, making it suitable for field use, although contamination remains a challenge. This article reviews recent developments in Foc molecular early detection technologies, evaluates the effectiveness of each method, and discusses the challenges and future prospects in implementing these technologies for Foc control. Furthermore, the results of the review will be applied to produce Foc-free banana seedlings through tissue culture.

Living on easy acces to finance and markets, will women entrepreneurs in MSMEs with prior experience be able to survive in the agriculture region?

Almas Farah Dinna Dewi, Handriyono, Isti Fadah, Dea Nova Agustiyaningsih

This study examines whether women entrepreneurs in Micro, Small, and Medium Enterprises (MSMEs) in East Java, which is an agrarian region, can sustain their businesses with easy access to finance, markets, and entrepreneurial experience. Using logistic regression analysis, this study reveals that access to markets and entrepreneurial experience have a positive impact on MSME performance, but access to finance has a negative impact. Contrary to common expectations, these findings suggest that having easy access to finance does not necessarily improve the performance of women-led MSMEs in agrarian settings. This highlights the need for a deeper understanding of the specific challenges facing women entrepreneurs in the region and suggests that other factors may play an important role in ensuring the sustainability of these enterprises.

Handriyono1, A F D Dewi2, I Fadah3, dan S R Ramadhan4

The growing tourism industry offers significant growth opportunities for Micro, Small, and Medium Enterprises (MSMEs), which play a significant role in the sector. This study aims to investigate and analyze the factors influencing the expansion of MSMEs in Indonesia's tourism industry, with a focus on the implications of gender differences among entrepreneurs. Using a quantitative approach, this study used a survey distributed through questionnaires to collect primary data samples from 217 MSMEs in Banyuwangi, Indonesia. Consisting of 93 male genders, and 124 female genders The path analysis method using SmartPLS was carried out to assess the direct and indirect relationship between variables that affect the performance of MSMEs. This study reveals that while innovation directly contributes positively to the growth of MSMEs, its indirect effects through destination branding are detrimental. This shows that the misalignment between innovation and brand strategy can hinder the growth of MSMEs. In addition, product quality, entrepreneurial orientation, and information technology significantly affect the growth of MSMEs through effective goal branding. However, communication and networking did not show a significant impact, pointing to the need for a more focused and efficient strategy in this area. In particular, gender-based analysis highlights the differences between male and female entrepreneurs, Through the study revealed that there was no striking difference in the factors affecting the growth of MSMEs no different from the gender differences of MSME actors. This reflects the broader gender equality goals outlined in the Sustainable Development Goals (SDGs) and reveals how these goals are represented in the tourism MSME sector. This research offers a new perspective by linking innovation strategies and destination branding with the growth of MSMEs in the tourism sector, while addressing the gender gap among entrepreneurs, thereby contributing to the discourse of gender equality in the context of tourism MSMEs.

Interaction of Irrigation Pattern and Nitrogen Dose on Growth and Productivity of Some Maize Varieties

Abd. Rahman Arinong1,2, Rusnadi Padjung3*, Muh. Farid3, Burhanudin Rasyid4, Harry5

Maize productivity cannot be separated from the interaction between genetics and the environment. An optimal environment must support genetic potential. The environment needs to be engineered to optimize maize productivity potential. The growing environment can be engineered by adjusting irrigation patterns and fertilization, especially nitrogen fertilizer. The interaction between the two will give a dynamic pattern to the growth and productivity of corn. Therefore, research related to the interaction of irrigation patterns and nitrogen doses is essential in supporting the sustainability of corn productivity. This research was conducted with a split-plot design that was repeated three times. The main plot was the irrigation system (three irrigation patterns), followed by the sub-plot, nitrogen dose (seven nitrogen doses). Observations focused on the agronomic characteristics of maize plants. based on the results of this study, irrigation patterns and/or nitrogen doses significantly affected all maize growth characters with various interaction patterns. Productivity, as the main character, showed a significant interaction between the interaction pattern of irrigation and variety, the interaction of nitrogen and variety, and the interaction of the three factors. These results indicate that each irrigation pattern has specific potential for the interaction dose and variety. Therefore, the results of this study can be a recommendation for modeling maize productivity, especially in the face of diverse rainfall patterns

Indriani, Muh. Ansar*, Zulkarnain Chairuddin

Wajo Regency is the second largest rice production center in South Celebes. Farmers often encounter challenges such as insufficient irrigation water to meet the water requirements of rice plants and the timing of harvest coinciding with the rainy season, mainly due to unpredictable weather patterns. Adjusting planting times and patterns based on water availability and sufficiency is essential to address these issues. This research aims to determine optimal rice planting times by evaluating water requirements and availability. Water requirements were calculated using Cropwat 8.0, while water availability was assessed based on the 80% Weibull probability method. The findings indicate that the lowest water requirement during the Rendeng season occurs in the early planting period of April II and the Gadu season in October III. The recommended planting periods for the Kalola Irrigation area are from April II to August I for the rendeng season and from October III to February II for the Gadu season. The water requirement for the rendeng season is 202.3 mm/dec, while for the Gadu season, it is 397.7 mm/dec.

Dryland Optimization Using Biochar Enriched with Alginate-Producing Bacteria to Improve Morphophysiology of Pakchoy (Brassica Rapa L)

Salensia Haryati Afonso1, Baharuddin Patandjengi2*, Burhanuddin Rasyid3, Ifayanti Ridwan Saleh4

The decline in the quality of drylands is hampering global agricultural production due to the low capacity of the soil to store water and nutrients. Biochar, with its high porosity and surface area, has the potential to improve soil structure as well as increase water retention capacity and nutrient availability. In addition, biochar combinations enriched with alginate-producing bacteria such as Azotobacter sp., Bacillus sp., and Pseudomonas sp. Can improve plant morphophysiology through nitrogen fixation mechanisms, phosphate solubilization, and systemic resistance to environmental stress. This study aims to review the role of alginate-producing bacteria-enriched rice husk biochar in increasing the growth and adaptation of Pakchoy plants (Brassica rapa L.) in dry land. This systematic review was carried out based on PRISMA guidelines, with literature selected from international journals in the last three years. Research shows that biochar acts as a carrier of microorganisms that can improve nutrient retention, water use efficiency, and overall soil health. The integration of biochar with microbes has been shown to increase crop yields, improve soil structure, and support nutrient cycling through increased soil microbial activity. Microbe-enriched biochar also increases the diversity of soil microbes that play an important role in the decomposition of organic matter and nutrient availability. However, research on the specific interactions between biochar and microbial strains is still limited, so further studies are needed to understand the mechanisms underlying this synergistic relationship. It is hoped that biochar materials enriched with microorganisms have the potential to be an innovative solution in facing the challenges of agriculture in dry land.

Fermentation of duck bone meal using mixed microorganisms to improve its nutritional quality

Surianti, Zainuddin, Siti Aslamyah, Hasni Yulianti Azis

Fermentation of duck bone meal using mixed microorganisms, such as Bacillus sp., Rhizopus sp. and Saccharomyces cerevisiae, is proven to be an effective method in improving the nutritional quality of feed ingredients. The fermentation process is able to break down complex compounds, such as protein and crude fiber, into simpler forms that are easily digested by cultured organisms. In addition, fermentation also increases the bioavailability of essential minerals, such as calcium and phosphorus, which support optimal growth of aquatic animals such as vaname shrimp. This research is expected to produce cheaper and environmentally friendly alternative feed ingredients to support the aquaculture industry, especially in the production of feed for vaname shrimp. This study aims to improve the nutritional quality of duck bone meal through fermentation using mixed microorganisms, namely Bacillus sp., Rhizopus sp., and Saccharomyces cerevisiae. The method used in this study involves variations in dosage and length of fermentation time. Duck bone meal was fermented with three doses of mixed microorganisms (0.5 mL, 1 mL, and 1.5 mL/100 g bone meal) and three lengths of incubation time (12, 24, and 36 hours). Proximate composition measured included protein, crude fat, crude fiber, Extracted Material Without Nitrogen (BETN), ash, and calcium. The analysis showed that fermentation significantly increased protein, crude fat, and calcium contents, and decreased crude fiber. The best treatment was obtained at a dose of 1.5 mL/100 g with an incubation time of 36 hours, which resulted in the highest protein content (42.7%), crude fat (23.46%), and calcium (10.46%). This improvement in nutritional quality is due to the enzymatic activity of microorganisms that can break down complex protein compounds, increase mineral bioavailability, and reduce anti-nutritional compounds. The results of this study indicate that fermentation with mixed microorganisms can be an effective method to improve the nutritional value of duck bone meal as a feed ingredient in the aquaculture industry.

Characteristic and Anticholesterol Agents of Dendrocalamus asper And Chromolaena odorata Extract Encapsulated in Maltodextrin-Chitosan by Spray Drying

D T Dermawan1, M Mahendradatta1, Zainal1*

Rebung (Dendrocalamus asper) and balakacida (Chromolaena odorata) leaves extracts have shown potential in lowering cholesterol. However, these extracts are prone to oxidation and damage. Therefore, encapsulation proves to be an effective way to enhance the stability and effectiveness of these extracts. This research aimed to analyze the impact of different concentrations maltodextrin and chitosan on the characteristics of the encapsulant. Additionally, we aim to identify the optimal concentrations and examine the effect of encapsulation on the reduction of cholesterol levels. This research method use utilizes a factorial complete randomized design to compare maltodextrin and chitosan. The comparative treatment of maltodextrin and chitosan carried out was A1 (95%:5%), A2 (90%:10%) and A3 (85%:15%), which was then used to determine the best treatment to be used in the anticholesterol test by comparing it with A0 (extract without encapsulation). The results of this research show that a higher concentration of chitosan affects the viscosity of the emulsion. This can result in lower efficiency, higher water content, and the formation of microporosity on the surface of the particles. Additionally, the ratio of maltodextrin to chitosan impacts the increase in water content during storage, color intensity, particle size, and water solubility. The optimal ratio of maltodextrin to chitosan is A2 (90%: 10%). The optimal ratio of maltodextrin to chitosan is A2 (90%: 10%). Furthermore, the spray drying encapsulation process does not impact the effectiveness extracts as anticholesterol agents, cholesterol reduction decrease of 21.33 ± 4.93 mg/dL for A0 and 23.33 ± 2.31 mg/dL for A2.

Extraction and characterization of lignin microparticles from coconut fiber with alkaline treatment and its potential as an antibacterial agent

I W Arnata1,*, A A M D Anggreni1, G Arda2 , N Masruchin3 and A I Wahyudiono1

Coconut fiber is produced in abundant quantities and utilized in various fields, but lignin, one of the most significant components, has not been optimally explored. This study aims to extract and characterize lignin microparticles from coconut fiber with alkaline treatment and to determine its potential as an antibacterial agent for Escherichia coli at various concentrations. The study was conducted through the stages of lignin extraction with alkaline treatment, characterization, and determination of lignin concentration as an E. coli antibacterial. The concentration of lignin as an antibacterial was carried out at 6 levels, namely 0%, 5%, 10%, 15%, and 20%. Lignin characterization includes lignin content, surface morphology, functional groups, thermal stability, and clear zone diameter. The results showed that coconut fiber lignin had a reasonably high yield with a homogeneous morphology in the form of a round shape, microparticle size, evident peak intensity of the lignin functional group spectra, and relatively high thermal stability. Lignin microparticles produce a clear zone diameter that is increasingly higher with higher lignin concentration, so they have the potential to be used as an antibacterial agent for E. coli in food product applications.

Comparative biology and damage potential of Callosobruchus maculatus on commercial mung bean and cowpea in Makassar, Indonesia

Asra Asra1,2, Wardani Syahrani1,2, Bhintang Maharani1,2, Laila Al Atsariyah1,2, Ravindra Chandra Joshi3,4, Ito Fernando5, M Bayu Mario1,2,*

The cowpea weevil, Callosobruchus maculatus (Fabricius) (Coleoptera: Chrysomelidae) is a primary pest of legume beans, including mung bean and cowpea. Infestation during storage can result in substantial economic losses due to larval consumption of the seed endosperm, leading to hollow seeds and reduced quality and quantity. This study investigated the biology of C. maculatus and its impact on commercial mung bean and cowpea in Makassar, Indonesia. The result showed that mung bean supported a higher population growth of C. maculatus compared to cowpea. This was evident in the higher number of adult C. maculatus produced on mung bean (228.22 adults) compared to cowpea (190.22 adults). Additionally, adult weight was influenced by host species, with females and males being heavier on mung bean than on cowpea. However, cowpea experienced a higher percentage of bean damage. Infestation by C. maculatus resulted in a greater number of damaged beans (95.16%) and a higher percentage of bean weight loss (31.69%) in cowpea compared to mung bean (78.95% and 22.65%, respectively). This damage poses serious challenges to bean storage, leading to perforated beans, reduced nutritional value, and decreased bean weight. Ultimately, these damages can have significant economic consequences for stored legume commodities. Understanding the biology of C. maculatus and its damage potential are essential for developing effective pest management strategies to protect legume crops from infestation.

M Bayu Mario1,2,*, Muhammad Taufik1,2, Ahmad Komaini1,2, Idul Anshar1,2, Paridah1,2, Ravindra Chandra Joshi3,4, Safira Nurul Izzah5, Ito Fernando6

The maize weevil, Sitophilus zeamais (Motschulsky) (Coleoptera: Curculionidae) is a major stored-product pest of cereal grains in Indonesia. This pest causes significant economic losses by reducing grain quality and quantity. This study investigated the host preference for four Indonesian cereal grains, i.e. rice seed (Mekongga cultivar), milled rice (IR-64 cultivar), maize seed (Jakarin cultivar), and sorghum seed (Soper 7 cultivar). The study employed the pairwise comparison method using six combinations namely (1) rice seed vs. milled rice, (2) rice seed vs. maize seed, (3) rice seed vs. sorghum seed, (4) milled rice vs. maize seed, (5) milled rice vs. sorghum seed, (6) maize seed vs. sorghum seed. The adults showed significant preferences among these tested grains. Milled rice was more attractive to S. zeamais adults than rice seed and maize seed. Sorgum seed was more attractive than rice seed and maize seed. However, S. zeamais adults showed no significant preferences when rice seed paired with maize seed and milled rice paired with sorghum seed.

A Nurmuksin1, A Iriany1,*, A Wahyudi1, W Warkoyo2, R Tonda3, N S Sebayang4, D E Puspita5, and M Sa'adu6

Abstract. Diabetes mellitus is a global chronic disease with a significantly increasing prevalence. The management of diabetes involves effective blood sugar control, often trough conventional therapy and lifestyle changes. Loranthus morinda citrifolia and stevia rebaudiana have the potential to serve as natural alternatives in diabetes management. Loranthus morinda citrifolia, a parasitic plant on the morinda citrifolia tree, contains bioactive compounds such as saponins,flavonoids, tannins, and alkaloids, which exhibit antidiabetic activities, including enanching insulin sensitivity and reducing blood sugar levels. Stevia, a natural sweetener with a glycemic index of zero, does not affect blood sugar levels and may help control blood sugar and insulin resistance. Based on literature review, their combination in tea offers dual benefits: lowering blood sugar levels and providing calorie-free sweetness. Although the literature suggest potential benefits, further research is required to confirm the effectiveness and safety of long-term use. With the growing interest in herbal and organic products, the development of noni mistletoe tea with stevia could meet the market demand for healthy alternatives in diabetes management.

Ashriyah Irfiana1, A. Masniawati1* dan Muhammad Fuad Anshori2

Cayenne pepper is a high-value horticultural commodity with a large market demand. However, the production of cayenne pepper in Indonesia, especially in South Sulawesi, has decreased due to the use of chemical fertilizers that harm the environment and health. This study aims to increase the production and quality of cayenne pepper through multi-cross (MC) crosses and the use of biofertilizers, as well as to examine the effect of biofertilizer concentration and F5 stable strains from MC crosses on the growth and productivity of cayenne pepper. The study used a Separate Plots Design with the main plot in the form of biofertilizer concentration: 0 ml/L (B0), 10 ml/L (B1), and 20 ml/L (B2), and the subplots were F5 cayenne pepper strains: G8-1-1 (V1) and G10-5-5 (V2). Data were analyzed using a two-way analysis of variance and the Least Significant Difference test for significant results. The results showed that the biofertilizer concentration significantly affected plant height, crown width, number of fruits per plant, and fruit length. The cayenne pepper line also significantly affected plant height, crown width, fruit weight per seed, and fruit length. However, there was no significant effect of the two treatments on stem diameter, number of productive branches, and fruit weight per plant, and there was no interaction between the two. The concentration of 10 ml/L and the G8-1-1 strain gave the best results for the growth and productivity of cayenne pepper.

Ireneus Seno Prasojo1, Wulan Syahril3, Nun Ainun2, Sri Wahyufita2, Rinaldi Sjahril4,*, Rafiuddin4, Muh Riadi4, Ahmad Fauzan Adzima4, Yunus Musa4, Edi

Taro is one of the underutilized food crops cultivated locally, and one of them is Indonesia. As a resilient crop, it can be developed to fulfill food security in areas with difficult food access. Few recent evidence related to taro plant diversity studies has been researched for some regions of Indonesia, especially Sulawesi Island. This plant has broad life niches and can withstand flooded and drought conditions. The effects of different environmental conditions can lead to differences in the characteristics of plants. Tracing the diversity of food taro by studying morphological appearance is one of the processes for taro variety characterization. This study uses morphometrics to evaluate the difference between taro plants from the Bantaeng and Tana Toraja district through leaf blade morphology. The sample was explored using a snowball sampling approach. Plants were planted ex-situ and observed for leaf morphological appearance; data were analyzed using morphoJ® software. Taro plants from Bantaeng (Colocasia esculenta, Xanthosoma sagittifolium) have larger sizes, although they have similar leaf shapes to taro from Tana Toraja. The results indicate that differences in environmental conditions impact morphological characters such as leaf size and shape variation among taro species. Further research is needed to evaluate taro morphology in broader areas, especially South Sulawesi, although samples and locations of this study are still limited.

The Effect of Beauveria bassiana and Metarhizium anisopliae Combination on the Survival of Spodoptera exigua Larvae in Vivo with Single and Combined T

A I M Taufan1, I D Daud2,* and V S Dewi3

Entomopathogens are microorganisms capable of infecting and causing death in pest insects, making them a potential environmentally friendly biological control agent. Two commonly used entomopathogens in pest control are Beauveria bassiana and Metarhizium anisopliae, which are fungi known to effectively infect various insect species, including Spodoptera exigua, a major pest of onion crops that is difficult to control. The combination of these two entomopathogens is considered to enhance pest control effectiveness through synergistic interactions between the fungi. This study aimed to evaluate the effect of a combination of Beauveria bassiana and Metarhizium anisopliae on the survival of Spodoptera exigua larvae in vivo. The treatments included the individual application of each fungus as well as their combination. This research was conducted in the Laboratory of Plant Pests and Diseases, Faculty of Agriculture, Hasanuddin University. Laboratory tests were performed using a Completely Randomized Design (CRD) method. The results showed that the combination of Beauveria bassiana and Metarhizium anisopliae provided more stable control of Spodoptera exigua larvae compared to the single treatments, with 100% mortality achieved at 6 DAA and a Lethal Time50 value of 2.943, while the efficacy was in the good category with a value of 52%.

Bijawang watershed is one of the watersheds in Bulukumba Regency with an area of about 17,138.92 ha which is used by the surrounding community as a source of irrigation. Soil erosion in the catchment area can cause sedimentation in irrigation canals. Sediment carried by water flow will settle at the bottom of the channel, reducing the channel's capacity to drain water and slowing the flow of water. The study aims to predict the erosion rate and erosion hazard level of mixed dryland agriculture in Bijawang Sub Das, using the MUSLE (Modified Universal Soil Loss Equation) equation. This research was conducted in Bijawang Watershed, Bulukumba Regency and the analysis of soil physical and chemical properties was conducted at the Soil and Water Physics Laboratory, Faculty of Agriculture, Hasanuddin University, Makassar in January - March 2024. This research predicts erosion with the MUSLE method, while the data used are the maximum daily rainfall data of Bulukumba Regency in 2014-2023, soil characteristics (texture, bulk density, structure, C-Organic, and permeability), length and slope, and crop management. The highest erosion is found in Mixed Garden I with mixed land use which is 2946.14.58 tons/ha/year. While the lowest erosion is found in Mixed Garden II with a pesebesar 33.16 tons / ha / year. The highest IBE value in the Bijawang watershed in Bulukumba Regency is 133.92 (very high), indicating that IBE is greater than the tolerated erosion. Very high TBE occurs in the land use of Kebun (clove) with an erosion value of 1530.55 tons/ha/yr and Mixed Garden I (clove and coffee) which is 2946.14 tons/ha/yr. High TBE is found in Mixed Farm III (cocoa, banana, durian and clove) with erosion of 396.93 tons/ha/yr and moderate TBE occurs in Mixed Farm II land use (pepper and clove) with an erosion value of 33.68 tons/ha/yr.

R Nurhikmayani1,*, A S Dewi1, M Jayadi1, N Juita1, B N Aisyah1

Soil contamination with cadmium (Cd) is a critical issue that demands urgent action, mainly due to its enduring consequences. Cd levels in the Tallo River exceed the maximum threshold set by environmental quality standards, which poses a contamination risk to rice farms in the Tallo watershed. Cd contamination in rice fields not only affects human health but also reduces crop productivity and has the potential to disrupt the delicate balance of soil microbial communities. This study aims to analyze the effect of Cd contamination on soil microbial abundance in rice fields around the Tallo watershed, Makassar. The measurement results showed that Cd levels in three locations ranged from 0.151 to 0.161 ppb, which is still below the pollution threshold. The total abundance of bacteria at site L1 was 7.4 x 10⁷ CFU/g dry soil, L2 was 5.6 x 10⁹ CFU/g dry soil, and L3 was 4.1 x 10¹⁰ CFU/g dry soil. The total abundance of fungi at location L1 was 7.4 x 10⁴ CFU/g dry soil, L2 was 5.1 x 10⁵ CFU/g dry soil, and L3 was 4.8 x 10⁷ CFU/g dry soil. Site L3, located in the Pampang area and further away from the Tallo River, showed the highest microbial abundance and lowest Cd levels (0.151 ppb). In contrast, site L1, close to the Tallo River and the Makassar industrial area, had the highest Cd levels and lowest microbial abundance.

Nurlina Kasim1*, Rusnadi Padjung1, Syatrianty A Syaiful1, Firayunita2, Kasmiati3

Abstract. Utilization of banana peel waste as liquid organic fertilizer is one of the solutions in managing household waste that is rich in nutrients. This study aims to analyze the effect of cocoa clone type (Theobroma cacao L.) and banana peel liquid organic fertilizer application on cocoa seedling growth. Three types of cocoa clones, namely MCC 02, Sulawesi 01, and Sulawesi 02, combined with various concentrations of banana peel liquid organic fertilizer (25 mL/L, 50 mL/L, 75 mL/L) as well as control, were applied to cocoa seedlings in this study. The results showed that MCC 02 clone gave the best results in terms of number of leaves (29.93 leaves), leaf area (190.1 cm²), and crown wet weight (64.38 g). Meanwhile, the combination of Sulawesi 02 clone with 25 mL/L banana peel liquid organic fertilizer application produced the largest stomatal opening area (129.79 μm²). Application of banana peel liquid organic fertilizer with a concentration of 50 mL/L gave optimal results in increasing leaf area (196.3 cm²), crown wet weight (60.90 g), and crown dry weight (25.83 g). This study proves that banana peel liquid organic fertilizer can increase the vegetative growth of cocoa seedlings, especially in leaf and crown parameters. Cocoa clone MCC 02 showed a better growth response than other clones, while banana peel liquid organic fertilizer concentration of 50 mL/L was the optimal dose to support seedling growth. Thus, the use of banana peel liquid organic fertilizer can be an environmentally friendly alternative to improve the quality of cocoa seedlings.
