Anak Krakatau Ash Cloud Shuts Four Key Airports and Halts Flagship School Meal Rollout

JAKARTA, Investortrust.id — State airport operator PT Angkasa Pura Indonesia, commercially known as InJourney Airports, extended the temporary shutdown of four major airports through 6:00 p.m. Western Indonesia Time on Monday, Sept. 7, 2026, as volcanic ash from Mount Anak Krakatau continues to blanket regional airspace.

The prolonged suspension affects Jakarta’s primary international gateway Soekarno-Hatta (CGK), Halim Perdanakusuma (HLP), Radin Inten II in Lampung (TKG), and Husein Sastranegara in Bandung (BDO).

The extended grounding of Soekarno-Hatta chokes Western Indonesia’s central passenger and commercial air corridor, cascading flight cancellations across Southeast Asia and freezing domestic airline operations. The intensifying ash plume is also interrupting key public sector rollouts, halting classroom operations across three provinces and temporarily freezing the central government’s multi-billion-dollar flagship nutrition program in affected disaster zones.

Aviation Regulators Enforce Strict Pre-Flight Checks

The latest directive extends an earlier operational halt that grounded eight regional airfields through Monday morning, including Budiarto Curug (BTO), Pondok Cabe (PCB), Taufik Kiemas (TFY), and Atung Bungsu (PXA).

Transportation authorities cautioned that shifting winds make timeline projections highly fluid as hazardous microscopic silicate particles continue to drift across commercial flight paths. Ground safety teams are running runway paper tests every 30 minutes across affected facilities to monitor particulate density.

"Safety remains our priority, and we are monitoring the latest situation based on information provided by BMKG," Transportation Minister Dudy Purwagandhi stated in an official release on Monday, Sept. 7. "We cannot yet confirm when this will end because atmospheric conditions are too dynamic."

Regulators ordered airlines to keep turbine engines sealed while parked on tarmac aprons to avoid particulate contamination. Ground crews must complete mandatory mechanical inspections on every airframe before flight operations resume.

"If aircraft must stay overnight, ground crews must cover the engines," Purwagandhi said during his Monday briefing. "Even after airports reopen, airlines must inspect the engines before operating to verify there is no ash inside, as we must guarantee flight safety."

Emergency School Closures Freeze Free Meal Deliveries

The widening fallout prompted the National Nutrition Agency, known as BGN, to suspend meal distribution under the central government’s Free Nutritious Meal (Makan Bergizi Gratis / MBG) program across disaster-impacted zones on Monday, Sept. 7.

The distribution pause follows mandatory distance learning directives issued by regional education authorities to protect school communities from airborne toxic ash. Remote learning mandates span Lampung through Tuesday, Sept. 8; Banten through Wednesday, Sept. 9; and Greater Jakarta under an open-ended review timeline.

"The safety of students and school staff is our primary consideration in adjusting MBG operations," said Khairul Hidayati, Head of Legal and Public Relations at BGN, in a written statement on Monday, Sept. 7. "When classroom instruction transitions to remote learning, school-based meal distribution mechanics must adapt to stay targeted, safe, and aligned with emergency response policies."

BGN confirmed that nutritional fulfillment service units (SPPG) will resume meal deliveries as soon as regional governments declare classrooms safe for standard on-site instruction.

150,000 Travelers Stranded as Cancellations Mount

The grounding of air traffic across western Java has triggered massive disruptions across the national transit grid, stranding an estimated 150,000 travelers. Official figures from the Ministry of Transportation show that the ash plume has disrupted 467 flights, consisting of 409 domestic services and 58 international operations.

Coordinating Minister for Infrastructure and Regional Development Agus Harimurti Yudhoyono urged airlines and terminal authorities to maintain full transparency regarding the cascading cancellations.

"The principle here is that passengers must continuously receive clear, accurate explanations. Airlines cannot withhold information," Yudhoyono stated on Monday, Sept. 7. "Even though this is an act of force majeure, we insist that carriers provide proper assistance, including seamless refund mechanisms for travelers who are unable to fly."

State Operator Deploys Cross-Java Evacuation Convoys

To alleviate passenger backlogs at Jakarta's primary hub, state-owned airport operator InJourney Airports launched an emergency Service Recovery Activation program. The company rolled out dedicated service desks across Terminals 1, 2, and 3 to supply stranded travelers with refreshments, designated waiting zones, and complimentary overland transit.

The operator mobilized an initial fleet of eight free charter buses departing Soekarno-Hatta on Sunday night, Sept. 6, dispatching two coaches each toward major Central and East Java urban centers: Yogyakarta, Solo, Semarang, and Surabaya.

"This bus deployment is part of our Service Recovery Activation protocol following the suspension of flights at Soekarno-Hatta due to detected volcanic ash," said InJourney Airports Corporate Secretary Group Head Arie Ahsanurrohim in a written briefing. "We will add more buses and departure slots as real-time passenger demand requires."

Regional Hubs and Rail Lines Tap Contingency Links

With primary runways offline in the capital corridor, the Ministry of Transportation is funneling international and domestic air traffic toward secondary airfields situated clear of the plume's trajectory. Designated alternate diversion hubs include West Java International Airport Kertajati in Majalengka, Ahmad Yani Airport in Semarang, Yogyakarta International Airport, and Juanda International Airport in Surabaya.

Transportation planners are synchronizing these regional gateways with state-owned rail operator PT Kereta Api Indonesia (KAI) to build overland transport bridges back into the capital.

"We must prepare overland transportation modes, particularly rail links, to facilitate passengers whose flights are diverted to regional hubs like Kertajati so they can complete their transit into Jakarta," Yudhoyono noted on Monday, Sept. 7.
