This study aims to analyze environmental law enforcement and corporate responsibility regarding the ecological crisis triggered by nickel mining activities in the coastal area of Pomalaa, Kolaka Regency. The research method used is empirical legal research (socio-legal) with a qualitative descriptive approach, combining library research from various journal literatures and regulations, as well as a remote interview with a key informant in Dawi-Dawi village. The results show three main findings. First, the manifestation of ecological damage has had multidimensional impacts, including mud flood disasters, damaged road infrastructure, coastal sedimentation that paralyses the economy of the Bajo fishermen, and public health threats in the form of skin diseases in children. Second, this crisis is rooted in maladministration and weak licensing supervision by the local government, evidenced by mining activities without a Borrow-to-Use Forest Area Permit (IPPKH) and the practice of dumping nickel slag waste into the sea without an AMDAL document or valid permits. Third, the Corporate Social Responsibility (CSR) instrument has proven to fail in mitigating the damage and has been reduced to mere charitable activities, thereby ignoring the essence of ecosystem restoration. In conclusion, the environmental crisis in Pomalaa is a direct result of the disregard for environmental law instruments. Therefore, it is urgent to enforce strict criminal and administrative laws to demand absolute environmental restoration from mining corporations.
