• Resumen

  • This study aims to examine how the integration of Islamic law (syariah) and customary law (adat) occurs within Indonesia’s legal system and to identify the opportunities and challenges arising from this integration. Employing a literature based approach and normative socio legal analysis, the research draws on constitutional, legislative, and judicial sources, supplemented by qualitative case studies from regions such as Aceh, West Sumatra, Bali, and Papua. The findings indicate that while there is significant potential for harmonization particularly through locally grounded dispute resolution mechanisms and hybrid legal practices structural and normative obstacles persist, including institutional fragmentation, normative conflicts in areas like inheritance, and human rights concerns. The study concludes that meaningful integration requires deliberate legal frameworks, inclusive policymaking, and legal education that embraces normative diversity. This research contributes to the broader understanding of legal pluralism in Indonesia and underscores the importance of recognizing diverse legal traditions to foster a more inclusive and culturally responsive justice system.
