JAKARTA - The DKI Jakarta Provincial Government resumed weather modification operations (OMC) on the 10th day, Sunday, January 25, 2026. This step is being taken as an effort to mitigate the risk of extreme weather that has the potential to trigger hydrometeorological disasters in Jakarta and its surroundings.
The implementation of OMC is coordinated by the Regional Disaster Management Agency (BPBD) of the DKI Jakarta Province by involving a number of institutions, ranging from BNPB, BMKG, the Indonesian Air Force, to other related elements. The operation is carried out using a CASA 212 A-2105 aircraft based at Halim Perdanakusuma Airport.
"This operation is the result of synergy between the DKI Jakarta Provincial BPBD, BNPB, BMKG, TNI Air Force, and other related elements," said the Head of the DKI Jakarta BPBD, Isnawa Adji, in his statement, Monday, January 26.
The 10th OMC was carried out through two flight sorties. The first sortie was carried out on Sunday morning with a focus on cloud seeding in the South Jakarta and South Tangerang areas.
The aircraft flew at an altitude of 5,000 to 7,000 feet, with the sowing area at a radial of 210-300 degrees and a distance of 10-20 nautical miles from Halim Perdanakusuma Airport.
In the morning sorti, the team used a seeding material in the form of Calcium Oxide (CaO) with a total weight of 800 kilograms.
Meanwhile, the second sorti was carried out in the afternoon with a focus on cloud seeding areas above Depok Regency.
The flight was carried out at the same altitude, namely 5,000-7,000 feet, with the sowing area at a radial of 120-240 degrees and a distance of 10-20 nautical miles from Halim Perdanakusuma Airport. In this sorti, 800 kilograms of CaO sowing material were used again.
Isnawa said the implementation of the 10th OMC was part of the DKI Jakarta Provincial Government's strategic steps to anticipate the potential for high rainfall in densely populated urban areas.
"This 10th day weather modification operation is part of early mitigation efforts to reduce the risk of high rainfall impacts in the DKI Jakarta area and its surroundings. The implementation of OMC is based on analysis of atmospheric conditions and continuous weather monitoring, so that cloud seeding can be directed to safer areas," said Isnawa.
According to Isnawa, the DKI Jakarta BPBD also continues to conduct daily evaluations of the implementation of OMC, as well as strengthening cross-agency coordination to ensure readiness for potential hydrometeorological disasters in the future.
In the midst of the OMC implementation, the BPBD DKI Jakarta continues to appeal to the public to be alert to the potential for moderate to heavy rain which can be accompanied by lightning, thunder, and strong winds. Residents are also asked to maintain the cleanliness of the environment and water channels to minimize the risk of flooding and flooding.
