Palm Oil Mill Effluent (POME) is a liquid waste from palm oil processing that holds great potential as a raw material for biogas production through fermentation in an anaerobic digester. Biogas is a form of renewable energy produced through fermentation in anaerobic conditions. This study aims to analyze the effect of fermentation time on the composition of biogas produced from POME. The research was conducted over a period of 30 days using anaerobic fermentation, with 200 liters of POME mixed with 2 probiotic capsules and 8 liters of water in the digester. Biogas composition including CH₄, CO₂, H₂S, and O₂ was analyzed every 5 days during the fermentation period.The results showed that fermentation time had a significant effect on both the production and composition of biogas. The volume and gas content increased over time, with optimal results achieved on the 25th day. On that day, the biogas composition consisted of 53.02% methane (CH₄), 26.32% carbon dioxide (CO₂), 0.054% hydrogen sulfide (H₂S), and 1.74% oxygen (O₂), with a total biogas volume of 62 liters. Based on these results, the 25th day was identified as the most optimal fermentation time for producing biogas from POME.
