Abstract

Rice is the main staple food in Indonesia, and Sidenreng Rappang District contributes significantly to rice production in South Sulawesi Province. However, rice distribution in this area faces significant challenges, including long marketing channels and high marketing margins, which disadvantage farmers. The Muhammadiyah United Economic Assembly plays an important role in optimizing distribution channels, providing access to financing to farmers, and facilitating cooperation between farmers and marketing institutions. This research used observation, interview, and documentation methods, with primary and secondary data. The results showed that the marketing margin of rice in Sidenreng Rappang District reached IDR 23,650/kg, with the largest profits enjoyed by wholesalers and retailers. Improving more efficient distribution channels can reduce marketing margins and improve farmers' welfare. Therefore, the role of the Economic Assembly of Muhammadiyah Association is crucial in creating a more efficient trade system and improving the economic welfare of the people in Sidenreng Rappang District.

Abstract

Rhychoporus spp., commonly known as the sago beetle Rhychoporus ferrugineus, is a pest that affects aren, rumbia, and coconut plants. Despite its pest status, the larvae of Rhychoporus spp. have long been recognized for their value as food and as ingredients in medicine and cosmetics. This comprehensive research, which thoroughly investigates the morphological characteristics and nutritional components of Rhychoporus spp. found in aren plants in Minahasa Regency, North Sulawesi Province, aims to provide a reliable and valid understanding of this species. The findings of this study have potential applications in the fields of entomology and food science. For entomologists, the detailed morphological characteristics of Rhychoporus spp. can aid in species identification and classification. For food scientists, the nutritional components of the larvae can be used to explore its potential as a food source and its applications in medicine and cosmetics. A descriptive method was used, involving field and laboratory research. The field study was conducted in Walensorit Village, Minahasa Regency. Morphological research used the Mizzi method, with measurements conducted using Carl Zeiss and Hirox KH8700 microscopes. The nutritional analysis included moisture, ash, protein, fat, carbohydrate, and fiber content, using standard methods such as drying, Kjeldahl analysis, Soxhlet extraction, and proximate analysis. The average body length of Rhychoporus spp. was 28.574 mm, with variations in abdomen length (8.936 mm), pronotum length (7.899 mm), head size (6.299 mm), and pronotum width (6.508 mm). The physicochemical analysis revealed that the larvae contain 70.04% water, 3.66% minerals, 1.35% calcium, 1.18% phosphorus, and 0.66% coconut minerals. The protein content was 7.78%, fat 19.04%, crude fiber 0.62%, and carbohydrates 2.33%. These comprehensive findings contribute to a better understanding of the species and its potential uses.

Abstract

Palm oil mill effluent (POME) is applied on cultivated farmlands at various stages by many farmers in southeastern Nigeria with many reporting that it helps to improve crop yield and productivity despite no availability of data to support their claims. This study was therefore designed to investigate the impact of POME on soil physicochemical parameters and soil enzyme activities in soil samples from POME irrigated farmlands. In this study, top and subsoil samples from control farmland unirrigated with POME, dumpsites and 10 m away from POME dumpsites in six different farmlands irrigated with POME labelled A – F were investigated using standard analytical procedures. The results of physicochemical properties of the soils including nitrogen, phosphorus, organic carbon, organic matter, cation exchange capacity and exchangeable cations indicated significant (P<0.05) in topsoil and sub-soils containing POME when compared with their corresponding control1 soils. The lipase activities of topsoil from dumpsites A-E and subsoil 10m away from dumpsite C indicated a significant increase (P<0.05) relative to the corresponding control soils. The effluents caused a significant (P<0.05) decrease in the dehydrogenase and catalase activities of top-soils and sub-soils from each of the dumpsites and 10m away from respective dumpsites when compared with their respective control soils. The findings of this study revealed that the application of POME on soil increases the contents of soil organic carbon, organic matter, exchangeable cations, and cation exchange capacity interfere with enzyme activities.

Abstract

This study investigates sago-based food processing businesses' cost structure, profitability, and sustainability trends in North Luwu and Palopo City, South Sulawesi, Indonesia. Despite sago’s strategic role as a traditional food and a climate-resilient crop, the industry faces declining raw material availability, low farmer income, and limited technological adoption. Using a combined qualitative-quantitative descriptive approach, including structured surveys and focus group discussions (FGDs), this research provides a detailed cost and trend analysis of micro and small- scale enterprises producing local sago foods such as bagea, dange, and kapurung. The findings reveal that while these businesses remain economically viable—with R/C ratios above 1.0 and the dange business reaching 2.1—profitability is constrained by small-scale operations, high input costs, and inadequate support systems. This study fills a critical research gap by shifting focus from upstream sago cultivation to downstream enterprise viability, offering a rare empirical insight into the dynamics of traditional food microenterprises in Indonesia. The novelty of this research lies in its integrated assessment of cost efficiency, scale potential, and policy implications. It proposes strategic interventions including modernizing processing technologies, strengthening farmer- producer linkages, and scaling up through cooperative models. The results provide actionable recommendations for local governments and agribusiness stakeholders aiming to revitalize indigenous food sectors. Future research should explore the design of sustainable enterprise clusters, examine consumer preferences for sago-based products, and evaluate the long-term impacts of technological and institutional interventions on sago industry resilience.

Abstract

Poultry production is a reliable animal protein source used in different communities. Malodor emitted from poultry houses limits their production and significantly contributes to air pollution. Mitigations are thus required to make broiler chicken production more environmentally friendly and productive. This study investigated the role of effective microorganism (EM) on broiler performance and odor emission from litter in broiler chicken production. A total of 180-day-old chicks were divided into four treatments: T0 (without EM-supplementation), T1 (EM-supplemented in water), T2 (EM-supplemented in feed), and T3 (EM-supplemented in water+feed), with three replicates of 15 birds each. Data on broiler performance, including water intake (WI), feed intake (FI), average weight gain (ADG), feed conversion ratio, and carcass characteristics, were measured and analyzed using one-way ANOVA in SPSS (version 25). Malodor agents were characterized by using gas chromatography. Significant (p<0.05) increase in WI and FI was delayed among chickens with EM treatments until 4th- 6th and 5th – 6th weeks, where T0 had lower (p<0.05) FI and WI, respectively. T3 had the highest (p≤0.05) increased ADG at the 5th and 6th weeks. Heart, wing, thigh, girth, and live weight did not differ (p>0.05) among treatments, while T0 had higher (p<0.05) liver and gizzard weight compared to the estimates from other groups. T0 recorded higher (p<0.05) gases, emitted from grower to finisher, compared with starter. EM treatment decreased (p<0.05) the number of gases emitted, with T3 recorded as the lowest. Thus, EM applications may alter the emission of odor-causing compounds in the broiler chicken litter without compromising its performance.

Abstract

Chili pepper (Capsicum frutescens L.) is an economically important horticultural crop, but its productivity in Indonesia has declined due to soil fertility degradation, excessive use of inorganic fertilizers, and unfavorable climatic conditions. This study evaluated the individual and combined effects of plant growth-promoting rhizobacteria (PGPR) and corn cob biochar on the growth and yield of chili pepper. A field experiment was conducted from December 2022 to May 2023 at Hasanuddin University, Makassar, Indonesia, using a split-plot design with three levels of biochar (0, 7.5, and 15 t ha⁻¹) and three concentrations of PGPR (0, 10, and 20 g L⁻¹). Data were analyzed using ANOVA followed by LSD at α = 0.05. Results indicated that neither PGPR nor biochar alone had significant effects on most growth parameters. However, their interaction significantly enhanced yield-related traits. The combination of 15 t ha⁻¹ biochar with 20 g L⁻¹ PGPR (M2P2) produced the highest fruit number (69.17 fruits plant⁻¹), fresh fruit weight (72.30 g plant⁻¹), and yield (3.62 t ha⁻¹). These findings demonstrate the synergistic role of biochar and PGPR in improving chili productivity and highlight their potential as eco-friendly inputs for sustainable chili cultivation.
