<![CDATA[Boyolali Regency, home to approximately 62,000 dairy cows, faces significant challenges related to the management of cow manure. To address this, the Boyolali Regency Government has introduced biogas digester technology to process cow manure, converting it into biogas for energy and digestate for fertilizer. This study evaluates the effectiveness of training, mentoring, and biogas digesters in enhancing the management of manure. The evaluation involves surveys, pre- and post-tests, and interviews with 160 participants, including 20 digester recipients from 2023 and 2024. Results indicate substantial improvements in participants' knowledge of biogas technology, with increases of 87.83% and 86.27% for 2023 and 2024 recipients, respectively. The study also highlights the environmental, economic, and social impacts of the program, including reduced methane emissions, cost savings, and enhanced soil fertility. Overall, the program has contributed to achieving sustainable development goals (SDGs), particularly in renewable energy, waste management, and sustainable agriculture.]]>
