Including Riza Chalid, These Are the Roles of 7 Suspects in the Alleged Petral Corruption Case
The Attorney General’s Office (AGO) has designated seven suspects in the alleged corruption case at Pertamina Energy Trading Limited (Petral) from 2008 to 2015. The suspects are alleged to have been involved in tender conditioning practices and internal information leaks that resulted in state losses.
Head of the AGO’s Special Corruption Crime Investigation Directorate, Syarief Sulaeman Nahdi, explained that the case originated from the procurement process for crude oil and refinery products that did not proceed competitively.
“Investigators found facts of actions involving leaks of internal secret information from PES or Pertamina Energy Services regarding crude oil and gasoline needs, as well as other information, carried out by one of the suspects,” Syarief said during a press conference at the Attorney General’s Office in South Jakarta on Thursday (9/4/2026).
That information is alleged to have been used to arrange tender winners and influence prices.
One of the suspects, Mohammad Riza Chalid (MRC), is identified as the beneficial owner of several companies participating in the tenders. He is alleged to have controlled the process through suspect IRW, who served as a director in affiliated companies.
“Mr. MRC, through Mr. IRW, conducted communications with procurement officials both at Petral and Pertamina, including with suspect Mr. BBG, Mr. IRW, Mr. MLY, and Mr. TFK,” he explained.
IRW acted as an intermediary bridging communication between private parties and internal officials, including conveying information related to the Estimated Own Price (HPS) and oil needs.
“Such communications involved tender conditioning and HPS value information, resulting in mark-ups or overpriced costs because the procurement became non-competitive,” Syarief continued.
Meanwhile, suspect BBG, who served as Manager of Commerce in the Marketing and Commerce Directorate of PT Pertamina, along with AGS as Head of Trading at Pertamina Energy Services (PES) from 2012 to 2014, are alleged to have facilitated the conditioned procurement process.
Suspect MLY, a Senior Trader at Petral, NRD as Crude Trading Manager at PES, and TFK as VP of ISC at PT Pertamina, are also alleged to have played roles in approving and executing the procurement mechanism that did not comply with regulations.
Following tenders conducted in this manner between Petral and Riza Chalid’s companies to supply refinery oil products from 2012 to 2014.
As a result of these practices, the supply chain became longer, and procurement prices, particularly for Gasoline 88 (Premium) and Gasoline 92, increased, harming the state’s finances.
“The tender or procurement process for crude oil and refinery products caused a longer supply chain and higher prices,” Syarief revealed.
“Especially for Gasoline 88 products, known as Premium 88, and Gasoline 92. Thus causing losses to PT Pertamina,” he added.
Here is the list of the seven suspects in this case:
BBG, as Manager of Commerce in the Marketing and Commerce Directorate at PT Pertamina;
AGS, as Head of Trading at Pertamina Energy Services or PES from 2012 to 2014;
MLY, as Senior Trader at Petral from 2009 to 2015;
NRD, as Crude Trading Manager at PES;
TFK, as VP of ISC at PT Pertamina;
MRC, Beneficial Owner of several companies participating in the tenders;
IRW, as Director of companies owned by MRC.
The suspects are charged under Articles 2 and 3 of the Law on the Eradication of Criminal Acts of Corruption. To date, investigators are still calculating the amount of state losses in the case together with the Financial and Development Supervisory Agency (BPKP).
