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.
