Abstract

Sumberkencono Village possesses significant horticultural potential, yet post-harvest limitations hinder its economic optimization. This program aims to empower the Sumberberas Farmer Group through the integration of vacuum frying technology, quality standardization (GMP), and business legality (NIB and P-IRT). The methodology followed a participatory technology transfer approach, including intensive production mentoring and digital marketing optimization. Results demonstrated a significant improvement in product quality, characterized by better texture and oil-content stability, alongside the successful formalization of business legality. The integration of Shopee and TikTok Shop as marketing channels further expanded the group's reach into the digital retail landscape. This initiative proves that the synergy between post-harvest engineering and administrative compliance is crucial for transforming traditional farmer groups into competitive agro-industrial units.

Abstract

Energy is an important factor supporting the fulfillment of human life needs and the economy in both developed and developing countries, including Indonesia. One energy source that has potential for development and implementation in Indonesia is biomass. Livestock manure is one of the biomasses available in Indonesia that contains methane gas which can be used as a biogas energy source. Initial substrate characterization is very important for understanding the potential and efficiency of anaerobic fermentation processes in biogas production. Cattle manure as lignocellulose biomass has physical and chemical properties that affect the rate of organic degradation and methane yield. The CHNSO test method uses CHNSO Elemental analyzer, Hemicellulose test uses the Chesson method, Total N test uses the Kjeldahl method, P and K methods follow SNI 7763: 2018. Research results showed C 41.27%, H 4.63%, N 0.954%, S n. a, O 18.01%, N-Total 1.365, P₂O₅ 0.797, K₂O 0.594, Hemicellulose 15.788, Cellulose 34.62, Lignin 29.85, Lignocellulose 80.26, Dry Matter 93.97, Ash Content 18.26, Crude Protein 7.43, Crude Fiber 35.85, Crude Fat 0.28, Methane Yield Content 109.80. Cattle manure has high lignocellulose content and optimal C/N ratio with methane yield of 109.80 mL/g VS, demonstrating potential as a renewable energy substrate as well as raw material for organic fertilizer rich in macro nutrients.
