This study analyzes the Provincial Road Improvement and Maintenance (PRIM) program in Lombok Barat, Indonesia, which integrates technical engineering frameworks with multi-stakeholder governance mechanisms to improve road maintenance performance. Using a case study approach, data were collected through official government records, complaint management systems, multi-stakeholder forum documentation, and bibliometric analysis of global research trends. Life Cycle Cost Analysis (LCCA) demonstrated that preventive maintenance under PRIM reduced total life cycle costs by 28-35% compared to reactive maintenance models. The establishment of the Road Traffic and Transportation Forum (FLLAJ) and implementation of the Anti-Corruption Action Plan (ACAP) strengthened transparency, accelerated complaint resolution within seven working days, and enhanced public trust. The PRIM model successfully aligned technical efficiency with governance innovation while directly contributing to multiple Sustainable Development Goals (SDGs) 9, 11, and 16. The findings offer practical lessons for other developing regions seeking to institutionalize integrated infrastructure governance frameworks that simultaneously optimize service quality, fiscal sustainability, and institutional accountability. © 2025 Tim Pengembang Jurnal UPI.
