The research method involves document analysis, stakeholder interviews, and field surveys. The results indicate that the synergy of customary law principles and the implementation of forestry law principles have a positive impact on the recovery of illegally converted palm oil land. Forestry harmonization enables active community participation, with empowerment as a key factor in natural resource management, bridging the understanding of customary and forestry law.
