Corruption Eradication Commission Reveals Fraud of Antam-PT Loco Montrado Collaboration Regarding Metal Anode Corruption

Jakarta – The Corruption Eradication Commission (KPK) revealed that there were findings of suspected fraud in the metal anode processing case between PT Antam and PT Loco Montrado (LCM). The fraud is related to the processing of gold raw materials with inappropriate results. Asep Guntur Rahayu, Acting Deputy for Enforcement and Enforcement of the Corruption Eradication Committee, said that the machine at PT Antam for processing gold raw materials was initially damaged. Then PT Antam borrowed the processing equipment from PT LCM through Siman Bahar (SB), who became a suspect in this case. “From PT Antam, yes, they then contacted SB’s brother, the owner of PT Loco Montrado, because Loco Montrado also has tools to refine this gold ore,” Asep said on Tuesday (21/10/2025).

The equipment of PT LCM can only separate high content gold. “Well, it just seems that these two tools are different, the tools owned by Antam and the tools owned by Loco Montrado are different,” he said. “Brother SB, the ore was stored but the refining was not carried out at the concerned PT, PT LM. He took it abroad, if I am not mistaken, to a neighboring country,” he added. Then there is a gold difference when calculating it. Asep gave an example, ore that should produce gold of a certain weight, but the results were below that. “For example, it should be like this, from the ore owned by Antam, we should get, for example, 1 ton. Well, it turns out that the result is not 1 ton, less like that, less than that,” he said. “Well, that’s what happened, then the loss was there, because of the difference in the machine and other things that couldn’t be done here. The fraud was there,” Asep continued. In this case, the Corruption Eradication Commission (KPK) named the president director of PT Loco Montrado, Siman Bahar (SB), as a suspect. Siman was charged with section 2 paragraph (1) or section 3 of the law on the eradication of corruption in conjunction with section 55 paragraph (1) 1st of the Criminal Code. In 2025, the Corruption Eradication Commission seized IDR 100.7 billion in cash from Siman Bahar. The money was allegedly obtained through corruption. Before Siman, the Corruption Eradication Commission (KPK) had already taken legal action against a former Antam official named Dody Martimbang. He was sentenced to 6.5 years in prison in a corruption case that cost the state IDR 100.7 billion. Most recently, the Corruption Eradication Commission announced PT Loco Montardo (LCM) as a suspect in corruption in PT Antam Tbk’s metal anode processing. The company was designated as a corporate suspect in this case. (ial/mo)
