JAKARTA - Pemerintah Provinsi DKI Jakarta melalui Badan Penanggulangan Bencana Daerah (BPBD) Provinsi DKI Jakarta kembali melaksanakan Operasi Modifikasi Cuaca (OMC) sebagai langkah kesiapsiagaan menghadapi potensi bencana hidrometeorologi ekstrem di wilayah Jakarta dan sekitarnya.

Pelaksanaan hari ketiga OMC di bulan November 2025 yang dilakukan secara berkelanjutan oleh BPBD DKI Jakarta bekerja sama dengan Badan Meteorologi, Klimatologi, dan Geofisika (BMKG) serta TNI Angkatan Udara (TNI AU).

Kegiatan OMC berpusat di Bandara Halim Perdanakusuma, Jakarta Timur, Jumat, 7 November, menggunakan pesawat Casa A-2114 milik TNI AU.

Operasi ini mencakup dua sortie penerbangan. Sortie 1 dilakukan pada pukul 09.07–11.22 WIB dengan area semai wilayah Taman Nasional Ujung Kulon dan Selat Sunda, pada ketinggian 8.000–10.000 kaki.Sementara Sortir 2 dilaksanakan pukul 12.53–15.28 WIB

Area semai: wilayah Selat Sunda, meliputi perairan barat Kabupaten Pandeglang dan Kabupaten Serang, pada ketinggian 10.000–10.500 kaki.

Kru udara yang bertugas terdiri atas Lettu Pnb Bintang, Kpt Pnb Fajar, dan Letda Pnb Krisna, dengan total bahan semai 1.600 kilogram NaCl (garam higroskopis).

Kepala Pelaksana BPBD Provinsi DKI Jakarta, Isnawa Adji, menjelaskan bahwa pelaksanaan operasi ini merupakan kelanjutan dari rangkaian upaya mitigasi yang dilakukan secara intensif untuk mengurangi potensi dampak cuaca ekstrem di Jakarta.

“Operasi Modifikasi Cuaca hari ketiga terus difokuskan untuk mengurai awan potensial pembawa hujan lebat di sekitar Selat Sunda dan wilayah barat Banten. Dengan langkah ini, diharapkan intensitas hujan yang masuk ke wilayah Jakarta dapat ditekan,” ujar Isnawa dalam keterangannya, Sabtu, 8 November.

Isnawa menjelaskan, hasil observasi menunjukkan kondisi atmosfer yang mendukung proses penyemaian. Pada sortie pertama, terpantau awan jenis Cumulus dan Stratus dengan puncak mencapai 10.000–11.500 kaki di wilayah Ujung Kulon dan Selat Sunda, disertai presipitasi ringan di area tersebut.

Sementara itu, pada sortie kedua, tim mendeteksi awan jenis Cumulus Congestus dengan puncak antara 10.000–11.000 kaki di wilayah Pandeglang dan perairan selatan Pandeglang.

Selain itu, suplai massa udara basah dari arah barat daya dan barat Banten masih terpantau aktif, yang turut mendukung pertumbuhan awan hujan sejak pagi hingga sore hari.

“Kegiatan OMC ini terus kami evaluasi setiap hari bersama BMKG dan TNI AU. Tujuannya agar distribusi hujan dapat dikendalikan, sehingga potensi genangan dan banjir di wilayah DKI Jakarta dapat diminimalisir,” tambah Isnawa.

BPBD Provinsi DKI Jakarta mengimbau masyarakat untuk tetap waspada terhadap potensi hujan lebat disertai angin kencang dan petir, serta memastikan saluran air dan drainase di lingkungan sekitar tetap bersih agar aliran air tidak tersumbat.

JAKARTA - The DKI Jakarta Provincial Government through the DKI Jakarta Provincial Disaster Management Agency (BPBD) has again carried out the Weather Modification Operation (OMC) as a precautionary measure to deal with potential extreme hydrometeorological disasters in the Jakarta area and its surroundings.

The implementation of the third day of OMC in November 2025 which was carried out in a sustainable manner by the DKI Jakarta BPBD in collaboration with the Meteorology, Climatology and Geophysics Agency (BMKG) and the Indonesian Air Force (TNI AU).

OMC activity centered at Halim Perdanakusuma Airport, East Jakarta, Friday, November 7, uses the Casa A-2114 aircraft belonging to the Indonesian Air Force.

This operation includes two flight sorties. Sortie 1 was carried out at 09.07'11.22 WIB with the Semai area of Ujung Kulon National Park and Sunda Strait, at an altitude of 8,000'10,000 feet. Meanwhile, sort 2 was held at 12:53'15.28 WIB

Area Semai: the Sunda Strait region, covering the western waters of Pandeglang Regency and Serang Regency, at an altitude of 10,000'10,500 feet.

The air crew on duty consisted of First Lieutenant Pnb Bintang, Kpt Pnb Fajar, and Lt. Pnb Krisna, with a total material of 1,600 kilograms of NaCl (hygroscopic salt).

The Head of BPBD DKI Jakarta Province, Isnawa Adji, explained that the implementation of this operation was a continuation of a series of mitigation efforts carried out intensively to reduce the potential impact of extreme weather in Jakarta.

The third day of the Weather Modification operation continues to focus on unraveling the potential clouds of heavy rain carriers around the Sunda Strait and the western region of Banten. With this step, it is hoped that the intensity of rain entering the Jakarta area can be suppressed," Isnawa said in his statement, Saturday, November 8.

Isnawa explained that the observational results showed atmospheric conditions that supported the seeding process. In the first sortie, Cumulus and Stratus clouds monitored with peaks reaching 10,000 11,500 feet in the Ujung Kulon region and the Sunda Strait, accompanied by mild precipitation in the area.

Meanwhile, in the second sortie, the team detected Cumulus Congestus clouds with a peak of between 10,000'11,000 feet in the Pandeglang area and the southern waters of Pandeglang.

In addition, the supply of wet air masses from the southwest and west of Banten is still being observed to be active, which also supports the growth of rain clouds from morning to evening.

"We continue to evaluate this OMC activity every day with the BMKG and the Indonesian Air Force. The goal is that the distribution of rain can be controlled, so that the potential for inundation and flooding in the DKI Jakarta area can be minimized," added Isnawa.

BPBD DKI Jakarta Province appealed to the public to remain alert to the potential for heavy rain accompanied by strong winds and lightning, as well as ensure that waterways and drainage in the surrounding environment remain clean so that water flow is not clogged.
