Abstract	This study investigated the optimization of methane production through the co-digestion of pig manure (Sus scrofa domesticus) and corn silage (Zea mays) using a batch biodigester. Five treatments with varying concentrations were applied to determine the most effective ratio for methane production. Methane output was monitored for 30 days using a gas leak detector. Treatments 2, 3, and 4 produced the highest yields, exceeding 9,999 ppm, indicating significant digestive performance. Statistical analysis via ANOVA and Tukey HSD test confirmed significant differences among treatments, demonstrating that the selected co- digestion ratios effectively enhance methane production efficiency in batch biodigester systems.
