JAKARTA, thekabarnews.com—The Corruption Eradication Commission (KPK) received 2,526 public complaints from across the country during the first half of 2026, highlighting the public’s role in reporting suspected corruption.

KPK data show that officers completed the initial verification of 2,217 reports, equivalent to about 87.8 percent of all submissions received between January and June.

The remaining reports had not completed that stage by the end of the reporting period. Verification does not mean that KPK has confirmed a corruption offense.

KPK uses this stage to determine whether a complaint falls within its jurisdiction and contains enough information for further assessment.

Of the verified submissions, KPK placed 654 under further examination and completed its assessment of another 617. The outcomes of those 617 reports were:

508 archived
60 required further clarification
44 referred for internal KPK follow-up
Five transferred to external agencies

These categories account for all 617 completed assessments. An archived report should not automatically be described as false.

KPK may archive a submission because it falls outside the agency’s authority, lacks sufficient initial evidence or cannot proceed for another procedural reason.

People submitted most complaints through letters, which accounted for 1,719 reports. Another 481 reached KPK through direct submissions or public demonstrations.

The KPK Whistleblower System received 170 reports, while the agency recorded 123 submissions by email. Telephone calls accounted for 31 reports, and two arrived through the national SP4N-LAPOR public service platform.

Members of the public can file reports through the official KPK Whistleblower System, call center 198, email and other channels listed on the KPK’s public complaint procedure page.

KPK advises complainants to provide a clear chronology, relevant identities and preliminary supporting evidence.

The agency also recommends that whistleblowers avoid publishing their reports because public disclosure may affect confidentiality and the investigation.

DKI Jakarta generated the highest number of recorded submissions at 421. East Java followed with 278 reports, while West Java recorded 238.

Central Java contributed 166 complaints and North Sumatra registered 136. Together, these five provinces accounted for 1,239 reports, or about 49 percent of the national total.

The province associated with a submission does not necessarily identify where the alleged misconduct occurred.

A complainant may live in one province while reporting conduct involving another region or a national institution.

KPK’s data also identified law enforcement as the leading complaint sector, with 41 reports. Infrastructure followed with 36, while state finance accounted for 30.

Public participation remains an important entry point for detecting suspected corruption, but every complaint must pass verification and review before investigators can decide whether further action is justified.

A public report alone neither establishes that corruption occurred nor proves the responsibility of any person or institution.

KPK thanked members of the public who submitted information and encouraged future complainants to use official channels.

Complete reports supported by relevant documents give the agency a stronger basis for verification, clarification and possible enforcement.
