Produktivitas Biogas dengan Input Feses Sapi dan Air Rendaman Tandan Kosong Kelapa Sawit (TKKS)

Abstract

This research was conducted to determine the best composition when producing biogas. This study used data analysis of the Paired Sample T-test with 2 repetitions for each parameter. The treatment used was P0 (cow feces + soaking water of empty palm oil bunches); and P1 (cow feces + soaking water of empty palm oil bunches + bioactivator). Of the 2 treatments, namely without administration of bioactivator and administration of 5% bioactivator. The results showed that the addition of 5% bioactivator had a significant effect on the gas produced, maximum production in both treatments occurred on day 28, namely at P1 with a pH of 7.61 resulting in a gas pressure of 416.925 pa and a gas volume of 20 L. Meanwhile, P1 with a pH 7.91 produces a gas pressure of 588.6 pa and a gas volume of 30 L.
