This Community Service Program (CSP) aimed to implement a refugia system to support the conservation of natural enemies and the biological control of plant pests in soybean, peanut, and lettuce cultivation at the Experimental Farm of the Faculty of Agriculture, Universitas Wijaya Kusuma Surabaya (FP-UWKS), Banjarbendo, Sidoarjo. The program was conducted for one month in January 2026 using a participatory approach that integrated socialization, field demonstrations, hands-on practice, mentoring, monitoring, and evaluation. The activities focused on introducing the ecological functions of refugia plants as habitats and food sources for predators and parasitoids, thereby strengthening Integrated Pest Management (IPM) practices. The implementation involved planting flowering refugia species around crop plots, identifying natural enemies, and observing changes in pest populations and ecosystem conditions. The results indicated increased participant knowledge and practical skills regarding environmentally friendly pest management strategies. The refugia plants established successfully and attracted beneficial insects, including lady beetles, spiders, praying mantises, dragonflies, and parasitoids, which contributed to the natural suppression of plant pests. Participants demonstrated greater awareness of biodiversity conservation and reduced dependence on synthetic pesticides. Furthermore, the Experimental Farm has become a demonstration site for sustainable agricultural practices, supporting education, research, and community outreach. The program highlights that habitat management through refugia is a practical, low-cost, and environmentally sustainable innovation that can be replicated in other agricultural areas.
