Peran Lembaga Adat dalam Menyelesaikan Sengketa Tanah di Desa Detubinga Kecamatan Tanawawo Kabupaten Sikka

This study aims to analyze the role of the Lio Tribe Customary Institution in resolving land disputes in Detubinga Village, Tanawawo District, Sikka Regency, and identify supporting and inhibiting factors. The study used a qualitative method with a descriptive approach. Data were collected through in-depth interviews, observations, and documentation of five informants selected purposively and snowball, namely the village head who is also the Traditional Elder, two disputing parties, and two indigenous community members. The analysis used the interactive model of Miles and Huberman with John Burton's conflict resolution theory (roots of conflict, interests, needs, and problem solving). The results of the study indicate that the customary institution plays a role as a facilitator and mediator through the Kula Kame customary deliberation and the tracing of the history and lineage of the Aku Rina We'e land. The dispute is resolved on the difference in sources of legitimacy of land rights, namely genealogical relationships and ancestral inheritance on the one hand, and hereditary control and cultivation on the other. Supporting factors include community trust, family values, customary norms, and the tradition of deliberation, while inhibiting factors include differing claims, differing understandings of land history, and limited evidence. Resolution not only ends the disturbance but also maintains social relations and fosters practical and relational peace.
