Abstract

This study aims to analyze the effect of production land area on the income of coffee farmers in Pargarutan Jae Village, South Tapanuli Selatan. The method used is a quantitative approach involving 109 coffee farmer respondents selected using the accidental sampling method. Data were collected through questionnaires, observations, and documentation, then analyzed using Structural Equation Modeling Partial Least Square (SEM PLS). The results show that the production land area has a significant influence on increasing coffee production, which in turn positively impacts farmers’ income. The majority of farmers have a last education level of vocational high school/general senior high school and are in productive age, with most incomes at the lower-middle level. The validity and reliability of the research instruments have been well tested, with loading factor and AVE values meeting the criteria for convergent and discriminant validity. These findings indicate that managing and increasing the production land area is a key factor in improving the welfare of coffee farmers in the area.

Abstract

Solid waste management in Indonesia still faces a major service gap, as reflected by open dumping, open burning, and disposal into water bodies. In Lima Puluh Kota Regency, 81.57% of the 2024 waste generation was reported as unmanaged, while the Payakumbuh Regional Landfill became inoperable following an explosion and landslide in late 2023. This community service program aimed to strengthen the capacity of the PKH Kepompong Waste Bank in Jorong Sopan to manage household organic waste through Source-Based Waste Processing Technology (TOSS). The program employed a sequence of activities: awareness-raising on source segregation, introduction to the TOSS workflow, and hands-on training on producing eco-enzyme from fruit waste as a bio-activator, followed by composting practice using a 30×30×30 cm bamboo box. A total of 37 waste bank members participated, with an emphasis on practical skill development. The results indicate that participants improved their understanding of organic–inorganic segregation, were able to prepare eco-enzyme, and practiced composting so that decomposed material could be harvested as compost. Key enabling factors included the post-landfill disruption urgency, the waste bank’s institutional support, and simple locally available materials; constraints involved consistent segregation, moisture/aeration control, and the eco-enzyme fermentation period. Simple SOPs, community monitors, and basic indicator recording are recommended to sustain routine adoption. TOSS implementation has the potential to reduce open burning and river dumping, minimize odors and flies, and divert the dominant organic fraction into inputs for home gardening. Compost can be used for household gardens or marketed locally.

Abstract

Agricultural intensification has increased the volume of residues and by-products generated across farming systems, while conventional disposal practices continue to create environmental burdens. This systematic literature review examines how agricultural waste is converted into higher-value products within a circular bioeconomy framework. Using a PRISMA-based approach and Scopus as the main database, the review screened the literature and synthesized 10 studies that met the final eligibility criteria. The included studies were grouped into four valorization pathways: fuels and energy carriers, biocomposites and bio-based materials, catalysts and functional carbon materials, and biomaterials produced through biotechnological processes. The evidence shows that fuel-oriented pathways, including pelletization, co-combustion, and biogas-based utilization, are the most technologically mature and currently offer the clearest route to scale. Material-based pathways, especially biocomposites and paper substitution, offer greater value addition and resource efficiency, but their industrial expansion remains constrained by processing costs and system integration. Agricultural residues also show strong potential as precursors for catalysts and functional carbon materials for environmental remediation, while fungal bioconversion offers an emerging route for producing protein-rich biomass. Across pathways, the review identifies a recurring trade-off between technological maturity, value addition, and implementation complexity. The main contribution of this review is a cross-pathway synthesis that compares agricultural waste valorization not only by product type, but also by circularity features, readiness, and evidence strength. Future research should prioritize integrated techno-economic assessment, life-cycle assessment, standardized circularity metrics, and pilot-scale validation to support large-scale implementation.

Abstract

Micro, small, and medium enterprises (MSMEs), particularly those managed by women in rural areas, play a crucial role in supporting family and local economies. However, this potential is often hampered by limited access to technology and understanding of modern business management. The Ruhama women's group in Simpang Kapuak Village, Mungka District, faces similar challenges in its local gambir tea production business. This community service program aims to address these obstacles through strategic interventions in digital marketing and financial management. Implementation methods include outreach, theoretical training, and intensive practical mentoring. The activity stages are systematically designed, starting with needs analysis and program implementation, and ending with impact evaluation, measured by increasing empowerment levels. The results demonstrate significant improvements in digital literacy and financial management skills among participants. 85% of participants are able to create promotional content for products on social media, and 92% understand the basic concepts of simple financial record keeping. Close collaboration with the village government also strengthens program synergy, aligning with the regional development vision. The program has not only succeeded in improving technical capacity but also fostering an entrepreneurial spirit and independence, which are essential foundations for the economic sustainability of local communities.

Abstract

This study analyzes how credit risk, liquidity, capital adequacy, bank size, and intermediation performance influence the profitability of Regional Development Banks in Indonesia. Profitability is proxied by Return on Assets, while credit risk is proxied by Non-Performing Loan, liquidity by Loan to Deposit Ratio, capital adequacy by KPMM/CAR, bank size is represented by the natural logarithm of total assets, while intermediation performance by Net Interest Margin and loan distribution. This study uses a quantitative approach based on quarterly panel data from 17 Regional Development Banks during the 2018–2025 period. The data are analyzed using panel data regression in Stata, with three estimation approaches: the Common Effect Model, Fixed Effect Model, and Random Effect Model. The model selection test shows that the Fixed Effect Model is the most suitable estimation model. The findings show that all independent variables simultaneously affect ROA. Partially, NIM positively and significantly affects ROA, whereas NPL has a significant negative effect on ROA. Meanwhile, LDR, KPMM, bank size, and loan distribution do not significantly affect ROA. These results suggest that BPD profitability is more strongly determined by credit quality and the ability to generate net interest income.

Abstract

Cooperative health serves as a primary indicator of business credibility; however, the Koperasi Konsumen Syariah Pegawai Negeri Politeknik Pertanian Negeri Payakumbuh (KKSPN-PPNP) encounters significant obstacles in conducting systematic assessments due to limitations in human resource competence and the persistence of semi-manual reporting systems. The absence of such measurable evaluations negatively impacts the cooperative's internal accountability and its external bargaining position. This community service initiative aims to enhance the board's managerial capacity in independently compiling health assessment documents, in strict adherence to the Regulation of the Deputy for Supervision of the Ministry of Cooperatives and SMEs Number 06/PER/DEP.6/IV/2016. Employing a Participatory Action Research (PAR) approach, the program was implemented through a structured framework comprising socialization, classical training, and intensive mentoring to thoroughly analyze the seven vital aspects of health assessment. The results indicate a significant improvement in the administrators' technical understanding regarding financial ratio analysis and the implementation of early risk mitigation strategies. The primary output of this program is the generation of a valid Cooperative Health Assessment Report, which functions as an instrument of transparency during the Annual Members' Meeting (RAT) and serves as a strategic prerequisite for accessing banking financing. This achievement establishes a foundation for cooperative governance that is increasingly adaptive, accountable, and competitive.
