Volcanic Ash Delays KPK Witness Questioning in West Lombok Corruption Cases
Kabarsaji.com – Flight disruptions caused by ash from Mount Anak Krakatau have forced Indonesia’s Corruption Eradication Commission, or KPK, to postpone witness examinations in several corruption investigations. The travel disruption affected witnesses expected to attend questioning at the agency’s Red and White Building in Jakarta.
One of the delayed examinations involved Lalu Rudi Iskandar, chair of the West Lombok Regency General Elections Commission. He had been scheduled to appear before KPK investigators on September 7, 2026, in connection with the commission’s ongoing corruption inquiries.
The witness was unable to comply with the summons following flight delays to Jakarta due to volcanic ash from Mount Anak Krakatau.
KPK spokesperson Budi Prasetyo delivered that explanation to journalists in Jakarta on Tuesday. The rescheduling illustrates how travel interruptions can affect legal proceedings even when investigators and witnesses are prepared to move forward with a planned examination.
Ash Cloud Disrupts Air Travel
Mount Anak Krakatau erupted on September 5, 2026, producing volcanic ash that spread across several areas and interfered with airline operations. Airports affected by the disruption included Soekarno-Hatta Airport, which serves the Jakarta area and is one of Indonesia’s key aviation gateways.
Volcanic ash can make air travel unsafe and may lead airlines or airport authorities to delay, divert, or temporarily halt flights. In this instance, the resulting delays prevented the West Lombok election commission chief from reaching Jakarta in time for the scheduled KPK summons.
The delay does not alter the underlying investigation. It means investigators must set a new date for the witness examination while taking account of travel conditions and the witness’s ability to attend. Such interviews are a central part of corruption inquiries because they allow investigators to clarify events, review relationships between parties, and compare testimony with documents and other evidence.
West Lombok Investigation Began With Sting Operation
The postponed questioning is linked to corruption cases involving the West Lombok Regency Government. The cases came to public attention after a sting operation targeting West Lombok Regent Lalu Ahmad Zaini on July 20, 2026.
One day later, on July 21, 2026, the KPK named Lalu Ahmad Zaini and Sudirman, president director of PT Air Minum Giri Menang, as suspects in an alleged conflict-of-interest case involving the procurement of goods and services.
The anti-corruption agency also identified three people as suspects in a separate alleged bribery matter within the West Lombok Regency Government: Lalu Ahmad Zaini, Sudirman, and Alvonsus Gani, president director of PT Meconel Sistim Instrument.
The allegations involve public procurement, an area in which government decisions can determine which companies receive contracts for goods, services, or projects. Investigators are examining whether official authority and business interests were improperly connected in the awarding of such work.
Allegations Involve Rp12.4 Billion
The KPK suspects that the regent received as much as Rp12.4 billion through the alleged corrupt conduct. Of that figure, Rp10.8 billion is tied to the alleged conflict of interest, while Rp1.6 billion is connected to the alleged bribery case.
The Rp1.6 billion allegation followed the award of a West Lombok government project to PT Meconel Sistim Instrument. The separate amounts reflect the KPK’s division of the case into allegations involving a potential conflict of interest and alleged bribery.
Witness examinations remain important as investigators continue to establish the sequence of decisions, communications, and transactions relevant to both matters. A delayed appearance is therefore a procedural complication rather than a conclusion about the allegations or the individuals involved.
The KPK’s decision to rearrange questioning also highlights the practical effects of natural events on public institutions. Volcanic activity can affect transportation networks, government schedules, business travel, and legal processes far beyond the immediate area of an eruption.
For the West Lombok investigation, the next stage will include rescheduled witness interviews and the continuation of evidence-gathering tied to the procurement and project-award allegations. The cases remain allegations under investigation, while the KPK continues its examination of the suspected Rp12.4 billion in corrupt proceeds.
