<![CDATA[The transition from fossil fuels to renewable energy is a strategic step in addressing the energy crisis and the impacts of climate change. This study aims to analyze the potential of cow dung waste as a source of biogas-based electricity at Duta Lembu Farm, South Sumatra. The research employed a quantitative approach through field observations, interviews, literature review, and theoretical calculations of biogas volume, electricity generation, greenhouse gas emission reduction, and economic benefits. The results show that 210 kg of cow dung per day can produce 6.3 m³ of biogas, equivalent to 6.77 kWh/day or 203.1 kWh/month. This energy is sufficient to supply electricity for approximately 13 households or power 90 LED lamps, while also reducing greenhouse gas emissions by 157.5 kg CO₂/day. Economically, the utilization of biogas can save electricity costs of about Rp293,276.4 per month with a payback period of around 20 months. Thus, biogas utilization from cow dung is proven to be technically, economically, and environmentally feasible as a sustainable renewable energy solution.]]>
