Deteksi Jumlah Bakteri Total dan Coliform pada Sludge dari Proses Pembentukan Biogas Campuran Feses Sapi Potong dan Feses Kuda

Abstract

This study aims to determine the amount of total and coliform bacteria in sludge from the process of forming a mixture of biogas feces of beef cattle and horse feces. The method used in this study is the experimental method in the laboratory using a completely randomized design with 3 treatments, ie P1 = C / N ratio of 25, P2 = C / N ratio of 30 and P3 = C / N ratio of 35 and replications 6 times. To determine the effect of treatments, data were analyzed with ANOVA and Duncan test. The results showed that the mixture of feces of beef cattle and horse feces with various C / N ratio had significant ffect on total bacteria and coliform in sludge. Treatment P3 (C / N ratio 35) to produce the total number of bacteria (4.95 x 107 cfu / g) and coliform (6.33 x 106 cfu / g) the lowest.
