Stabilitas Digester Anaerobik Satu Tahap dalam Produksi Biogas pada Variasi Temperatur Menggunakan Reaktor Batch

Anaerobic digestion is the decomposition of organic matter by microbes into methane, carbon dioxide, and hydrogen sulfide in absence oxygen. This study aimed to obtain stability one stage anaerobic digester biogas production that was seen through pH alkalinity parameters. The process carried out varying temperature, which 35 °C, 45 55 °C with maintained 7 (± 0.2). Analysis assess reactor using samples taken from overflow. profile produced relatively stable a range between 6.8 - 7.3. resulting aalkalinity 3.500 – 4.500 mg/L. volume at respectively are 2065 mL, 3830 4570 mL highest concentrations methane (CH4), Carbon dioxide (CO2) trace Hydrogen Sulfide (H2S) temperature oC obtained value composition each 89,000 %, 11,000 0,011 %.
