This study aims to quantify the biogas potential of beef cattle waste in Pati Regency, specifically the methane (CH₄) content, and to formulate mitigation measures for greenhouse gas (GHG) emissions generated from this waste. The method used is a quantitative method based on the Intergovernmental Panel on Climate Change (IPCC) approach, supported by field observations, interviews with livestock farmers from several sub-districts, and cattle population data sampling. The results indicate that the potential methane gas production in Pati Regency reaches 1,763 m³ per day, with the largest potential in Jaken District at 201 m³/day and Margoyoso District at 160 m³/day. Furthermore, greenhouse gas emissions from beef cattle waste in Pati Regency are estimated to reach 5.49 GgCO₂ eq. In conclusion, Pati Regency has great potential to utilize beef cattle waste as a renewable energy source in the form of biogas, while facing a significant threat from unaddressed methane emissions. Therefore, a SWOT analysis-based mitigation strategy is needed, including developing a pilot methane gas processing project involving collaboration between livestock breeders, academics, and local governments, as well as increasing community participation through education on the benefits of environmentally friendly waste management.
