Abstract

In this research, biogas is produced from Palm Oil Mill Effluent (POME) by fermentation of cow dung using a stirred reactor and purified by various CO2 and H2S removal techniques. The variables in this study were: composition of cow dung (55%, 60%, 65%, 70%, 75%, 80% w/w), amino acid composition (0.5%, 1%, 1.5% w/w) and length of fermentation time (2, 6, 10, 14, 16 days). The fixed variables were stirring speed (100 rpm), temperature (30oC) and reactor volume (100 L). This research also investigated the effect of using a lime packed reactor on the purity of methane gas. From the results of first stage of fermentation, it was found that the optimum composition of cow dung-POME was at 60% and the fermentation time was 14 days. In the second stage of fermentation using optimum results at first stage compared to fermentation of cow dung without POME, the results of measuring the gas pressure produced in 60% cow dung-POME fermentation were 17.5 Psig greater than fermentation of cow dung without POME of 15 Psig.

Abstract

Banyaknya jumlah peternak sapi di Indonesia memiliki pro dan kontra. Limbah ternak, terutama kotoran, merupakan hal yang biasa dihasilkan dari peternakan sapi. Pengelolaan kotoran sapi yang buruk menyebabkan bau, kontaminasi air, dan pertumbuhan mikroba berbahaya. Biogas dari kotoran sapi dapat digunakan untuk menghasilkan energi alternatif. Biogas dari biodigester tradisional biasanya tidak dimurnikan. Sebuah biodigester terintegrasi sederhana dengan perangkat pemurnian atau penyerap dapat menghilangkan polutan dari biogas. Alat pemurni/adsorber sirkuit biodigester menghilangkan kontaminan biogas tanpa peralatan terpisah. Penelitian ini menggunakan metode eksperimen dengan percobaan produksi biogas dan penyerapan gas H2S dengan dua kali percobaan. Hasil penelitian menunjukkan bahwa perancangan alat biodigester ini memiliki hasil penyerapan yang baik dan menunjukkan kadar H2S sesuai sesuai dengan standar mutu biogas SNI 8019:2014.
