Abstract

Cilembu sweet potato farmers' dependence on synthetic chemical pesticides raises concerns about their impact on health, the environment, and agricultural sustainability. This Community Service Program (PKM) aims to empower farmers through education and training in the production of biopesticides from locally sourced plants. Implementation methods include outreach, demonstrations of biopesticide production from materials such as neem and soursop leaves, and hands-on field training. The results of the activities indicate an increase in farmers' understanding and skills in utilizing biopesticides as an environmentally friendly pest control alternative. The program concludes that education and utilization of locally sourced plant-based biopesticides have proven effective as a practical solution to reduce dependence on chemical pesticides while simultaneously supporting sustainable agriculture for Cilembu sweet potato farmers.

Abstract

Sumedang Regency is one of the main food buffer zones in West Java, yet rice productivity is threatened by soil degradation caused by excessive use of inorganic fertilizers. This initiative aims to encourage the adoption of organic fertilizers, including rice husk biochar and fermented animal manure, and to raise farmers’ awareness of sustainable soil fertility. Implemented in May 2026 in Banyuasih Village, Tanjungkerta District, the initiative included soil test-based outreach, technical mentoring, and demonstration plots covering 2 hectares. Results show that adoption rates rose from 33.3% to 88.9% of farmers; soil organic matter content increased from 1.85% to 2.12%; rice growth and yield components (IF 20) improved by up to 31.3%; and estimated yield increased by 24.1% compared to conventional practices. It is concluded that combining scientific evidence, accessible inputs, and intensive mentoring effectively accelerates the adoption of sustainable agricultural technologies.
