<![CDATA[The study discusses that land is one of the essential elements in the life of Indonesian society, especially due to the agrarian nature of the nation and its heavy dependence on natural resources. Since before the colonial era, customary law communities have recognized systems of land ownership and management regulated by customary law, including ulayat rights that grant collective authority to indigenous communities over the land within their territories. This type of research is qualitative in nature. The research design is field research, with data collected through interviews, observations, and document studies. The results show that 1) the resolution of land disputes through customary law is effective, relying on deliberation, mediation, and local wisdom that align with the principles of justice and public interest (maslahah) in siyasah syar’iyyah; 2) the main supporting factor is the community’s trust in customary institutions as entities capable of maintaining, enforcing, and preserving customary values as well as resolving various social issues fairly and with dignity. This trust arises because customary institutions are seen as an important part of community identity, possess strong social legitimacy, and are considered to better understand the needs and values of the local society compared to formal state institutions; 3) the study emphasizes the importance of strengthening the role of customary law through the integration of siyasah syar’iyyah values and adaptive regional regulations. By incorporating the principles of justice and public interest from siyasah syar’iyyah into customary law, supported by clear and harmonious regional regulations, the resolution of social problems at the local level can be more effective and just.]]>
