Zero Waste dari Panti: Mewujudkan Kemandirian Lingkungan melalui Pelatihan Pengolahan Sampah Organik

Abstract

Organic waste dominates household refuse and, when unmanaged, contributes to methane emissions and environmental nuisances. This community engagement program at Kasih Agape Orphanage addresses the issue by developing a small-scale zero-waste model through education, hands-on training, mentoring, and field application in the orphanage garden. The objectives are to improve participants’ knowledge of waste classification and 3R principles, to build practical skills in producing liquid organic fertilizer and compost from kitchen waste, and to institutionalize simple routines for sustained practice. The method integrates contextual socialization sessions, guided practice for fermentation and aerobic composting, two-week mentoring to monitor process parameters, and direct application of the products to vegetable beds. The program results indicate improved understanding and routines of segregation at source, successful production of liquid organic fertilizer and compost suitable for garden use, and the establishment of basic standard operating procedures, logbooks, and weekly duty schedules. These outcomes demonstrate a feasible pathway to reduce waste streams, strengthen self-reliance in garden inputs, and cultivate zero-waste habits within a residential social institution. The program concludes that coupling education with practice and light institutional governance is effective and replicable for similar settings.
