Utilization of Livestock Manure as Biogas and Liquid Organic Fertilizer (LOF) in Sumbermulyo Village, Pesanggaran, Banyuwangi

Abstract

Biogas, generated by anaerobic bacteria breaking down organic matter, presents an energy alternative. Sumbermulyo, a Banyuwangi village, relies on dragon fruit farming and goat herding, facing shortages of subsidized urea fertilizer and LPG. The solution: utilizing goat manure for methane gas, replacing LPG. This community service project introduces a biogas processing pilot in Sumbermulyo, producing liquid organic fertilizer for local use. A fixed dome concrete biogas digester is constructed on a farmer group's land in 14 days, with peak pressure at 1.06 atm. Chemical analysis shows 0.032% N, 0.009% P, 0.144% K for the test digester, and 0.044% N, 0.005% P, 0.195% K for the reference digester, offering a sustainable energy and fertilizer solution for the community.
