Industrial mining activities in Mimika Regency, Papua, particularly by PT Freeport Indonesia, have caused serious ecological damage to river and marine ecosystems. This study aims to analyze the environmental impacts of tailing waste disposal into the Ajkwa River, Otomona River, and coastal areas, as well as evaluate the weaknesses in management and mitigation efforts. The research method used is a descriptive qualitative approach with field studies, documentation, and literature review. The results of the study indicate that heavy metal pollution has caused degradation of mangrove ecosystems, seagrass beds, and disruptions to biodiversity and the health of the Amungme and Kamoro indigenous communities. Weak regulations, lack of independent oversight, and the exclusion of indigenous peoples from decision-making processes are the main obstacles to addressing this damage. Environmental policy reforms based on ecological justice, strengthened law enforcement, and participatory ecosystem restoration are needed as efforts to restore the environment in the Mimika region.
