The increasing demand for livestock products has led to a significant rise in manure quantities, which negatively impacts the environment by contributing to climate change and increasing greenhouse gas (GHG) emissions. Livestock production primarily generates methane (CH4) and nitrous oxide (N2 O), which are major emissions from these systems. Various studies have explored effective strategies to reduce CH4 and N2 O emissions produced from enteric fermentation and manure management. This study aims to develop an effective strategy to reduce CH4 and N2 O emissions from cattle fed with rice straw. The study was conducted by measuring CH4, N2 O, temperature, and humidity from cow manure in 50 cattle sheds. Data analysis was performed using the IPCC guidelines, and the analysis of feed ingredients and livestock manure was conducted using proximate analysis. The Analytical Hierarchy Process (AHP) method was employed to determine effective strategies for reducing CH4 and N2 O emissions. The results indicated that the highest emissions of CH4 and N2 O were 171.321 ppm and 51,053.539 ppm, respectively, with an average temperature of 29.51°C and humidity of 79.21% RH. Three alternative strategies were identified as effective in decision-making based on their weight order: releasing methane gas into the atmosphere, storing methane gas in the soil, and utilizing methane gas as green energy (biogas). © 2025, HARD Publishing Company.
