This document provides the final report of a study on public participation and access to information in the AMDAL (Analisis Mengenai Dampak Lingkungan) process in Indonesia. The study assesses the effectiveness of public involvement since regulations were established in 2000. It uses 10 case studies and expert interviews to identify patterns of implementation, limiting factors, and recommendations. Key findings include that public comments have had varying value and impact but have not significantly contributed to better AMDAL processes or decisions. Recommendations focus on clarifying objectives, roles, and criteria for public involvement as well as developing capacity and financial support. The study aims to inform revisions to public participation regulations and guidelines for the AMDAL system in Indonesia.
