Abstract

This study evaluates the effectiveness of Indonesia’s Social Forestry (SF) policy implementation from 2016 to 2024 through a document-based meta-analysis and systematic literature review. The policy, initiated under Ministerial Regulation No. P.83/2016, aims to address forest tenure inequality and improve community welfare through legal access to forest management. A total of 23 documents, including official government reports, NGO evaluations, and peer-reviewed publications, were analyzed using descriptive quantitative and thematic qualitative methods. The findings reveal that Social Forestry has significantly expanded legal access to forest areas, reaching over 8 million hectares through approximately 11,000 decrees, and has generated positive economic, social, and environmental outcomes. The program enhanced household income, strengthened institutional participation, and promoted conservation practices such as agroforestry and forest zoning. However, implementation effectiveness remains constrained by weak institutional capacity, limited financing, inconsistent data integration, and inadequate cross-sectoral coordination. Strengthening local institutions, establishing interoperable reporting systems, and developing community enterprises through digital and market-based incentives are essential for long-term sustainability. The study concludes that the success of Social Forestry depends on collaborative governance and adaptive policies that balance administrative expansion with substantive socio-ecological outcomes.

Abstract

Tapioca processing in Indonesia generates high-strength wastewater that can emit substantial methane (CH4) without sufficient treatment. The objective of this study is to determine a site-specific methane emission factor (B₀) for biogas power generation based on an anaerobic covered lagoon (ACL) and compares it with the IPCC default. Research was conducted on biogas power plant based on cassava wastewater with a capacity of 2 × 1.5 MW in Central Lampung. Twenty-two months of full-scale monitoring database included wastewater flow, COD, biogas yield volume, and methane concentration across wet and dry seasons. The results show that covered anaerobic lagoon systems with biogas recovery can effectively reduce fugitive methane. Using AMS-III.H and IPCC methods, a strong linear relationship between methane production and COD removal produced a site-specific B₀ of 0.2302 kg CH4/kg COD (0.321 m3 CH4/kg COD), slightly below the IPCC value. Lower yield was likely influenced by seasonal dilution, operational variability, and partial degradation of cassava-based organics. Results of this research emphasize the need for site-specific emission factors to improve Indonesia’s GHG inventories and mitigation strategies.
