<![CDATA[This community service activity aims to map the circular economy potential based on by-products from the livestock and agricultural sectors in Gendro Village, Tutur District, Pasuruan Regency. The method used is a participatory approach (Participatory Rural Appraisal / PRA) through field observations, interviews, and focus group discussions with local farmers and ranchers. The data obtained was analyzed descriptively, quantitatively, and qualitatively to identify waste potential, its economic value, and opportunities for integration between sectors. The mapping results showed that out of 17 dairy farmers with a total of 117 cows, the average milk production reached ±2,800 liters per day, while cow manure waste reached 3.5 tons per day. About 60% of farmers have utilized this waste into organic fertilizer or biogas, while the rest is still disposed of into waterways. On the other hand, from 12 farmers with a total land area of 6.6 hectares, the harvest yield was around 90 tons per planting season, with agricultural waste reaching 80 tons. The ratio of waste to crop yield reaches 89%, indicating high potential for processing into value-added products such as compost, liquid fertilizer, and fermented feed. The integration of these two sectors demonstrates a natural closed-loop system at the village level, where agricultural waste can be used as feed, and livestock manure becomes organic fertilizer for agricultural land. The implementation of this circular economy model has the potential to generate additional economic value of IDR 45–60 million per year, reduce production costs by 20–30%, and reduce environmental pollution. Thus, Gendro Village has a great opportunity to be developed as a pilot village for a circular economy based on an integrated agroecosystem that supports food security and environmental sustainability]]>
