KPK Summons Businessman Robert Bonosusatya as Witness in Case of Former Kukar Regent

The KPK has summoned businessman Robert Priantono Bonosusatya (RPB). Robert has been called as a witness in the alleged gratification case implicating former Kutai Kartanegara (Kukar) Regent Rita Widyasari.

“The KPK has scheduled an examination of a witness in the alleged corruption offence of gratification in Kutai Kartanegara,” said KPK spokesperson Budi Prasetyo to reporters on Thursday (2/4/2026).

Budi did not explain what would be probed from Robert. The examination will be conducted at the KPK building in Jakarta.

For information, the KPK once searched Robert’s house in May 2025. The KPK seized a number of funds and documents.

“That on 14 to 15 May 2025, the KPK carried out a series of investigation actions in the form of a search of one house located in Kebayoran Lama, South Jakarta,” said KPK spokesperson Budi Prasetyo at the KPK building in Kuningan, South Jakarta, on Friday (16/5/2025).

In addition to the house, the KPK also searched six cars parked at Robert Bonosusatya’s house. The search was conducted from 20:00 to 01:00 WIB.

Rita’s Case

Rita was initially designated as a suspect in a bribery and gratification case in 2017. She was then tried in the gratification case.

In 2018, Rita was sentenced to 10 years in prison by the panel of judges at the Central Jakarta Corruption Court. Rita was also fined Rp600 million subsidiary 6 months imprisonment and revocation of political rights for 5 years.

The judges stated that Rita was proven to have received gratification of Rp110 billion related to project permitting in Kutai Kartanegara. Rita attempted to challenge the verdict.

Rita’s efforts failed after the Supreme Court rejected her request for review (PK) in 2021. Rita has been executed to Pondok Bambu Prison.

In addition to the gratification case, Rita remains a suspect in an alleged money laundering case. In July 2024, the KPK revealed that Rita also received money from mining entrepreneurs.
