Attorney General's Office Designates Three New Suspects in PT Asmin Mining Permit Corruption Case, Including KSOP Head

JAKARTA - The Attorney General’s Office (AGO) has designated three new suspects in the development of the alleged corruption case concerning the misuse of mining business permits for PT Asmin Koalindo Tuhup (AKT) in Murung Raya Regency, Central Kalimantan.

Director of Investigation for the Deputy Attorney General for Special Crimes (Jampidsus) Syarief Sulaeman Nahdi stated that one of the designated suspects is the Head of the Harbourmaster and Port Authority Office (KSOP) Rangga Ilung, initialled HS.

“First, suspect HS, who is the Head of the Harbourmaster and Port Authority Office or KSOP Rangga Ilung, Central Kalimantan,” said Syarief during a press conference at the Attorney General’s Office building in Jakarta on Thursday evening (23/4/2026).

Syarief explained that suspect HS is alleged to have abused his authority by granting sailing approvals to coal-carrying vessels owned by PT AKT and its affiliated companies.

However, HS knew that the coal transportation documents were invalid.

In addition, he is also suspected of receiving illegal monthly fund transfers from companies affiliated with Samin Tan, who is the beneficial owner of PT Asmin Koalindo Tuhup (AKT).

“Thus, 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 revealed.

These activities were carried out using documents from other companies unlawfully, including through PT AKT’s affiliated companies.

Meanwhile, suspect HZM, as the General Manager of PT OOWL Indonesia, played a role in creating coal laboratory test result documents or certificate of analysis (COA).

HZM is suspected of manipulating mining verification result reports by stating the coal’s origin from other companies, thereby allowing PT AKT’s illegal mining outputs to still be exported.

According to Syarief, HZM was initially uncooperative, skipping two investigator summonses before being forcibly brought in and designated as a suspect.

Currently, they are detained for the next 20 days at the Class I Cipinang Detention Centre.

This case is a development from the previous corruption case that implicated Samin Tan as the beneficial owner of PT AKT.

In the investigation process, the Jampidsus team has also conducted searches at two KSOP offices, namely in South Kalimantan and Central Kalimantan.

From those searches, investigators seized several shipping documents as well as electronic evidence related to the activities of the companies and related parties.
