Abstract. The increasing demand for renewable energy highlights the importance of utilizing livestock waste as a sustainable energy source. This study examines the biogas production potential from dairy cattle manure at Sirukam Dairy Farm in West Sumatra, Indonesia. Cattle manure and organic waste were co-digested at four mixing ratios with water (1:1:1, 2:1:1, 1:2:1, and 2:0:1, w/w). Substrate characteristics, including moisture content, total solids (TS), and carbon-to-nitrogen (C/N) ratio, were analyzed to evaluate their influence on biogas yield. Results showed that the 1:1:1 ratio achieved the highest cumulative biogas production (276 mL) with optimal substrate characteristics (moisture 89.2%, TS 10.8%, C/N 21). Lower performance was observed in the manure-only mixture (2:0:1), which yielded only 107.5 mL due to an imbalanced C/N ratio (7) and excessive nitrogen, leading to ammonia inhibition. The study confirms that optimal conditions for biogas production occur at moisture levels of 88–89%, TS of 9–11%, and C/N ratios between 20–30. These findings demonstrate the technical feasibility of utilizing livestock waste for renewable energy generation in Indonesia, providing a scientific basis for scaling up farm-based anaerobic digestion systems.
