Implementation of the Composter Method in Processing Household Organic Waste to Create Liquid Fertilizer in Salo Cella Village

Organic waste management is a significant environmental issue in Indonesia, where millions of tons of organic waste end up in landfills each year, producing methane gas that contributes to global warming and environmental pollution. According to Law Number 8 of 2008, organic waste consists of biodegradable residues from living organisms. Data from SPSN 2023 shows that 40.5% of household waste is food scraps. Salo Cella Village in East Kalimantan faces suboptimal organic waste management. This program aims to address the issue by using anaerobic composters and EM4 as a bioactivator to produce liquid fertilizer. The activity involves local women’s groups (PKK) and residents. The results indicate that household organic waste was successfully converted into valuable liquid fertilizer, reducing waste volume and helping to mitigate environmental problems. This liquid fertilizer is effective for various young plants, such as chili and vegetables. The program also raises community awareness about the importance of organic waste management and its use in sustainable agriculture.
