Waste in Indonesia remains an unresolved issue, with the amount of waste reaching 23 million tons per year in 2021. The traditional waste management system leads to ineffective handling of household and agricultural waste. This study focuses on the organic waste processing using Black Soldier Fly (BSF) larvae as an environmentally friendly and economical solution. BSF larvae can degrade up to 80% of the total waste processed, producing organic compost and leachate beneficial for agriculture. This research was conducted in Parongpong Village, West Java, where the majority of residents are farmers who rely on manure to cultivate their land. The use of BSF larvae in composting is expected to reduce dependence on chemical fertilizers and address the organic waste problem that surges post-harvest. This group-based waste processing model aims to tackle organic waste in the village environment using composting methods assisted by the biological agent BSF larvae. The results of the study show that using BSF larvae significantly reduces waste volume, with a processing efficiency of 14.68% remaining waste. The compost produced is rich in essential nutrients such as nitrogen, phosphorus, and potassium, which have the potential to improve soil fertility and plant productivity. Compost production with BSF larvae requires simple infrastructure and low operational costs. Each neighborhood unit can produce around 1.02 kg of compost per month, with the potential for large-scale production reaching 600 kg of compost per month from 1 ton of waste. Feasibility analysis shows that the composting model with BSF larvae can reduce organic waste problems, decrease waste disposal burdens, and improve environmental quality. The high-quality compost produced can be used by the surrounding community for agriculture, increasing crop yields and reducing reliance on chemical fertilizers. Additionally, this technology opens new business opportunities for the community, both in compost production and organic waste processing, which can improve the local economy and create jobs. This study also includes an analysis of the economic impact of the composting process with BSF larvae and the benefits of the composting model for the surrounding community. It is expected that this group-based integrated waste processing can reduce the amount of manure used, thus reducing the production costs in the agricultural sector for the surrounding community.
