The rising consumption of chicken has led to an expansion in poultry farming, resulting in increased accumulation of Broiler Chicken Manure. If not properly managed, this can lead to pollution and the spread of diseases. While Broiler Chicken Manure is often used as organic fertilizer, it emits nitrogen gases, contributing to odor problems. However, anaerobic digestion of Broiler Chicken Manure can produce biogas, offering an effective alternative energy source that helps reduce pollution and greenhouse gas emissions. This study investigates the biogas production potential of two types of Broiler Chicken Manure: Broiler chicken manure and Broiler Chicken Breed, Breeding period 45 and 440 days, respectively, with rice husk used as bedding material. The study focuses on two main aspects: 1) comparing the efficiency of biogas production from Broiler chicken manure and Broiler Chicken Breed, manure collection time, and the effect of mixing with rice husk, and 2) examining the impact of different mixing ratios of additive 4 type including Iron particles-A (Fe-A) with a size of <75µm, Iron particles-B (Fe-B) with a size of 75-180µm, Activated carbon powder-A (GAC-A) with a size of <75µm, Activated carbon powder -B (GAC-B) with a size of 75-180µm (Fe-A, Fe-B, GAC-A, GAC-B) at concentrations of 5, 10, and 20 mg/l. The results showed that Broiler Chicken Manure, with a 1:4 water-to-manure ratio and mixed with rice husk, had a methane production potential of up to 55 m³/ton. The highest biogas production was achieved with GAC-B at 5 mg/l, showing a 59.98% increase in biogas potential.
