Attorney General's Office Designates Three New Suspects in Corruption Case Involving Mining Boss Samin Tan
The Attorney General’s Office (Kejagung) has designated three new suspects in the alleged corruption case involving deviations and mismanagement in the mining operations of PT Asmin Koalindo Tuhup (PT AKT) in Murung Raya Regency, Central Kalimantan. One of those designated as a suspect is former Head of the Port Authority and Harbour Office (KSOP) of Rangga Ilung, Handry Sulfian.
The Director of Investigation at the Deputy Attorney General for Special Crimes (Dirdik Jampidsus) of Kejagung, Syarif Sulaeman Nahdi, revealed that the designation of these suspects is the result of further investigation into the case involving a corporation owned by Samin Tan (ST).
“Investigators at Jampidsus have conducted further probes into the alleged criminal corruption case of deviations and mining management at PT AKT in Murung Raya Regency. For this reason, we have designated three individuals as suspects today,” said Syarif during a press conference at the Kejagung’s Round Building in South Jakarta on Thursday (23/4/2026).
The three suspects are:
Handry Sulfian (HS), former Head of KSOP Rangga Ilung, Central Kalimantan;
Bagus Jaya Wardhana (BJW), Director of PT Asmin Koalindo Tuhup (PT AKT);
Helmi Zaidan Mauludin (HZM), General Manager of PT OOWL Indonesia.
“The suspects have been detained in Cipinang Class I Detention Centre for the next 20 days,” stated Syarif.
Syarif explained that suspect Handry Sulfian is alleged to have abused his authority by issuing Sailing Approval Letters (SPB) for the shipment of PT AKT’s coal using falsified documents. In fact, Handry knew that PT AKT’s mining permit had been terminated since 2017.
“Suspect HS, as Head of KSOP Rangga Ilung, issued sailing approval letters to PT MCM and other companies. However, suspect HS knew that the ship traffic documents for the coal cargoes belonged to AKT and were sold using falsified documents,” clarified Syarif.
Not only that, Handry Sulfian is alleged to have received monthly payments from PT AKT via Samin Tan. “As a result, the suspect did not conduct checks on the verification result reports from the Ministry of Energy and Mineral Resources as a requirement for issuing sailing orders,” he continued.
Meanwhile, Bagus Jaya Wardhana (BJW), as Director of PT AKT, is said to have collaborated with Samin Tan in conducting illegal coal mining and exports until 2025. They used documents from other companies to smuggle mining outputs from an area whose permit had already been revoked.
Suspect Helmi Zaidan Mauludin (HZM), as GM of PT OOWL Indonesia, acted as a surveyor who falsified Certificate of Analysis (COA) documents or laboratory test results.
“HZM was tasked with conducting checks, and as a surveyor, he performed verifications and produced documents of verification results or mining output reports to be submitted as requirements for issuing sailing orders from the Port Authority (KSOP) and coal royalty payments,” explained Syarif.
In this case, Kejagung has previously designated Samin Tan as a suspect. Samin Tan is referred to as the beneficial owner of PT AKT.
The Director of Investigation (Dirdik) of the Deputy Attorney General for Special Crimes (Jampidsus), Syarief Sulaeman Nahdi, stated that the company previously operated under a Coal Mining Business Work Agreement (PKP2B). However, the company’s permit was revoked in 2017.
Despite the revocation, PT AKT is alleged to have continued illegal mining and coal sales activities until 2025.
“After the revocation, PT AKT still continued unauthorised and unlawful mining and sales of mining outputs until 2025,” said the Director of Investigation of the Deputy Attorney General for Special Crimes (Jampidsus), Syarief Sulaeman Nahdi, during a press conference at Kejagung in South Jakarta on Friday (27/3).
