Policy-Relevant Insights into Household Biogas Adoption in West Java, Indonesia: Evidence from a Logistic Regression Analysis

This study examines the determinants of household biogas adoption among dairy farmers in West Java, Indonesia. Despite ongoing government efforts to promote renewable energy, adoption remains limited and often not sustainable. Using cross-sectional survey data from biogas users and non-users, a binary logistic regression model was applied to assess the role of socioeconomic characteristics, resource availability, and institutional support. The results indicate that perceived time savings, fuel-cost pressure, and participation in training programs are significant positive drivers of adoption. In contrast, higher levels of formal education and livestock ownership are associated with a lower likelihood of adoption, suggesting that resource availability alone does not guarantee use. Overall, the findings highlight that adoption depends not only on economic factors but also on how well biogas systems align with household practices and capabilities. The study provides policy-relevant insights for improving the design and implementation of biogas programs in rural Indonesia.
