Abstract
This community service activity aimed to introduce a greenhouse-effect solar dryer (GESD) technology for chili postharvest processing in Kedungweru Village. The main issue faced by farmers was high postharvest losses due to unpredictable weather and conventional open sun-drying methods. The implementation included problem identification, technical training, field demonstrations, and participatory-based mentoring and monitoring. The results showed a 4060% reduction in drying time compared to traditional sun drying, improved product quality in terms of color and hygiene, and increased selling prices by 2535%. The activity enhanced community technical capacity in postharvest management, strengthened food resilience, and promoted village-based economic development through appropriate renewable energy technology. This model is replicable in other chili-producing regions with similar agroclimatic conditions.
