Perbandingan Penambahan Air pada Proses Pembuatan Biogas dari Kotoran Sapi pada Praktikum Pengolahan Limbah Peternakan

Abstract

The technology of processing cattle manure for household-scale biogas production is discussed in this study. In the livestock waste management experiment, a comparison of the composition of water and cattle manure mixture was conducted to evaluate biogas production. A 60liter plastic drum was used as a digester, filled with 40 liters of slurry. The observation period lasted for 10 days, with varying ratios of water to manure mixture, which were 1:1, 1.5:1, and 2:1. Subsequently, the methane gas quality was tested at the Environmental Research Center for Agriculture in Jaken, Pati, Central Java. The experimental results indicated methane gas concentrations of 228,406.38 ppm for the 2:1 water to manure ratio, 195,337.56 ppm for the 1:1 ratio, and 110,969.13 ppm for the 1.5:1 ratio. The ANOVA test results for the water to manure ratio experiment showed that the treatments did not significantly affect the concentrations of CH 4 , CO 2 , and N 2 O (P>0.05).
