The Attorney General’s Office (AGO) has designated Samin Tan as a suspect in the corruption case concerning irregularities in the management of mining operations by PT Asmin Koalindo Tuhup (AKT) in Murung Raya Regency, Central Kalimantan. Here are the details of the case implicating Samin Tan. Director of Investigation at the Deputy Attorney General for Special Crimes, Syarief Sulaeman Nahdi, explained during a press conference on Saturday (28/3/2026) that Samin Tan is the beneficial owner of PT AKT, a coal mining contractor based on a Coal Mining Business Work Agreement (PKP2B) whose permit was revoked in 2017. After the revocation, PT AKT continued mining and selling mining products illegally and in violation of the law. These activities persisted until 2025. “Suspect ST, through PT AKT and its affiliates, unlawfully continued mining and sales using invalid permit documents, in collaboration with state officials tasked with supervising mining activities, thereby harming the state’s finances and/or economy,” Syarief added.
