Appreciation for Mining Corruption Disclosure in West Kalimantan, AGO Urged to Finalise Samin Tan Case

National coordinator of Jaringan Aktivis Nusantara (JAN), Ibrahim, has praised the Attorney General’s Office (AGO) for charging four suspects in a suspected corruption case involving the mismanagement of bauxite mining permits (IUP) for PT Quality Sukses Sejahtera (QSS) in West Kalimantan from 2017 to 2025. The suspects were named on Friday (22 May 2026), one day after Sudiarto, the beneficial owner of PT QQS, was charged. Ibrahim stated that the AGO should swiftly investigate the suspected illegal mining case involving PT Asmin Koalindo Tuhuf, whose beneficial owner is Samin Tan. Samin Tan has already been charged and is suspected of causing approximately Rp8 trillion in state losses. The AGO has unraveled the case structure and conducted searches to gather evidence for the Samin Tan case. However, no new suspects have been charged to date. The AGO previously stated that PT AKT used ‘flying documents’ from RKAB PT MCM for its illegal activities, and that Rp390 billion used by Samin Tan to pay fines to the PKH Task Force account originated from PT AC’s account. On 11 May 2026, during a protest at the AGO office, Ibrahim said his group submitted names of individuals who should be questioned to uncover the illegal mining case. Samin Tan is not acting alone; there are undoubtedly backers among businesspeople and officials protecting and profiting from the scheme, along with law enforcement personnel. Syarif Sulaeman Nahdi, Director of the AGO’s Special Crimes Directorate (Jampidsus), stated that the suspect charges were the result of further investigation. Hari Purwanto, Executive Director of the People’s Democracy Study (SDR), urged the AGO to reveal those involved in the Samin Tan corruption case. Febrie explained that they are still examining witnesses to implicate government officials in the case. Samin Tan (ST), founder of PT AKT, has been charged in the case. Investigators have detained him for 20 days. Boyamin expressed strong appreciation for the AGO’s investigation and hopes that those facilitating Aseng’s actions will also be charged. Notorious corrupt mining convict Supriyadi, involved in a Rp233 billion case, was caught loitering at a Kendari coffee shop during a PK hearing. The AGO is investigating alleged corruption in mining permit issuance in North Konawe from 2013 to 2025. The case is suspected to involve local officials and protected forest permits. Former KPK leader Saut Situmorang has called for the Corruption Eradication Commission (KPK) to explain the Rp2.7 trillion state loss in the halted Aswad Sulaiman case. The Corruption Eradication Commission (KPK) has officially halted investigations into alleged nickel mining permit corruption and bribery in North Konawe Regency, Southeast Sulawesi.
