Land has a very important position for human life. This is because almost all aspects of life are inseparable from the existence of land, but there is an imbalance between land and the number of people, which often results in disputes. Disputes are usually resolved by state law or customary law, however, there are several obstacles that often occur that do not go well. The purpose of this study was to find out what obstacles occurred in the Kajang tribal customary land dispute. The approach used in this study includes a qualitative descriptive approach. Retrieval of data used through (in-depth interviews, observation and documentation). Retrieval of research informants using purposive sampling. Data analysis used the Miles and Huberman analysis method with data reduction, data collection, data presentation and conclusion drawing steps. The obstacle that occurred in the Kajang tribal customary land dispute was that there were several individuals who claimed to be Ammatoa's extensions who took advantage of the conflict for personal gain. The lack of communication between PT Lonsum and the Kajang community led to (Misunderstanding) this conflict continued, where PT Lonsum wanted the Kajang indigenous people to prove that according to state law and asked to show a certificate of ownership of the land, while the Kajang indigenous people asked for a settlement according to customary law by bringing together PT Lonsum, the government, and Ammatoa along with stakeholders and members of the Kajang customary community. Indigenous people feel that the land managed by PT Lonsum is the customary land of the Kajang customary community and they demand that the land taken by PT Lonsum be returned, while PT Lonsum considers that the land that has been used for a long time is land that has an HGU certificate granted by the government.
