Abstract

Kotoran ternak sapi, ayam dan sampah organik adalah termasuk limbah padat yang dapat digunakan sebagai sumber energi melalui digester biogas. Penelitian ini bertujuan untuk mengetahui produksi biogas dari limbah tersebut melalui digester drum plastic volume 220 L dengan system batch. Penelitian ini menggunakan tiga digester yaitu digester 1 berisi kotoran ayam dan air (50 : 50) , digester 2 berupa campuran kotoran ayam, sapi dan air (30:20:50) dan digester 3 berisi kotoran sapi, sampah organik dan air (30:20:50). Digester tersebut kemudian ditutup rapat sampai 130 Hari dan diukur suhu serta tekanan biogas. Hasil penelitian menunjukkan temperatur harian berkisar antara 260-310 C, tingkat keasaman (pH) 7 – 7,62. Produksi biogas masing masing digester diukur dengan manometer jarum dan persamaan gas ideal. Produksi biogas yang berada di ban penampung kemudian dilakukan uji nyala dengan kompor biogas dan uji mesin penggerak. Produksi biogas digester 2 lebih baik daripada digester lainnya dengan total volume kumulatif gas 1059,84 L, waktu nyala api kumulatif 4302 detik dan dapat menyalakan mesin penggerak dengan cara dicampur gas elpiji 3 kg. Digester 1 menghasilkan produksi biogas dengan volume kumulatif 1010,70 L dan waktu nyala api 4034 detik. Produksi biogas digester 3 paling rendah dengan volume kumulati gas 790,33 L dan waktu nyala api kumulati sebanyak 2370 detik.

Cow manure, chicken manure and organic waste are solid wastes that can be used as an energy source through a biogas digester. This study aims to determine the production of biogas from the waste in a batch digester system. This research uses a digester in the form of a plastic drum with a capacity of 220 liters. There were 3 treatments consisting of Digester 1 containing cow manure and water (50: 50), Digester 2 in the form of a mixture of cow manure, chicken manure and water (30:20:50), Digester 3 containing cow manure, organic waste and water (30:20:50).The digester is then closed tightly for 130 days. The results showed that the daily temperature ranged between 260-310 C and the acidity (pH) 7 -7.62. The biogas production of each digester was measured by a needle manometer and the ideal gas equation. The biogas production in the reservoir tire is then carried out a flame test with a biogas stove and a test engine drive. The production of biogas digester 2 is better than other digesters with a cumulative total volume of 1059.84 L of gas, a cumulative flame time of 4302 seconds and can start the engine by mixing 3 kg of LPG gas. Digester 1 produces biogas with a cumulative volume of 1010.70 L and a flame time of 4034 seconds. The production of biogas digester 3 is the lowest with a cumulative gas volume of 790.33 L and a cumulative flame time of 2370 seconds.
Keywords: Cow dung, chicken manure, organic waste, digester of batch type
