The Weda Bay Industrial Park (PT IWIP) has been accused of conducting self-weighing and verification of minerals instead of using licensed inspection agencies, allegedly violating mineral trading rules and potentially causing losses in Non-Tax State Revenue (PNBP). The Director of the Center for Energy and Mining Law Studies believes this is a serious issue in mineral trade accountability, as self-operation can easily lead to falsification of quantity and grade data, resulting in state losses that could be substantial and involve criminal corruption. He stated that this violates government regulations and related PNBP laws, calling for the DPR to set up a special committee, government audits, and legal accountability. The DPR's Commission XII also found during a visit to IMIP that IWIP operates its own weighing equipment, with inspectors present but not conducting verification, and that there is a lack of national regulatory oversight in the land-based transaction chain. Commission members reported to the President, noting that IWIP can obtain ore without state records, while the government only has data from inspection agencies, and the Ministry of Energy has not established control measures for overland truck sales. Data from the Ministry of Energy and Mineral Resources shows that mineral-related PNBP reached IDR 117.26 trillion from January to November 2025, and by early December it had reached IDR 120 trillion, achieving 96% of the annual target of IDR 124.5 trillion, with the possibility of exceeding the target. However, if the IWIP issue proves true, it will affect the authenticity and integrity of PNBP.
