Ensuring the sustainability of child protection initiatives at the village level remains a significant challenge due to weak institutionalisation and limited support from local governance structures. Although the Community-Based Integrated Child Protection programme (Perlindungan Anak Terpadu Berbasis Masyarakat or PATBM) was designed as a community-driven mechanism emphasizing prevention, public education, and early referral systems for cases of violence and exploitation against children, its implementation frequently depends on external assistance and project-based support. This article examines the institutionalisation of PATBM through Village Regulations as a legal strategy for strengthening sustainable child protection governance in villages in Bone Regency. This research conducted with socio-legal approach with a case study design, combining normative analysis of village governance and child protection regulations with empirical analysis of local institutional practices. The findings demonstrate that the adoption of four Village Regulations formally incorporating PATBM into the Village Community Institution structure has strengthened legal legitimacy, clarified institutional responsibilities, and integrated child protection into village governance mechanisms. While concerns regarding fiscal capacity emerged during the regulatory process, these challenges were addressed through activity-based budgeting arrangements that provide greater flexibility and financial accountability. The study concludes that Village Regulations constitute an effective legal governance instrument for ensuring the sustainability of community-based child protection initiatives.
