JAKARTA - The DKI Jakarta Provincial Government and the National Disaster Management Agency (BNPB) agreed to take advantage of weather modification technology (TMC) at the end of 2022 in Jakarta.

This was revealed when the Acting Governor of DKI Jakarta Heru Budi Hartono met with the Head of BNPB Suharyanto at Graha BNPB, East Jakarta.

Suharyanto revealed that the weather modification cooperation using special equipment was also carried out with the National Research and Innovation Agency (BRIN) and the Indonesian Air Force.

"With the potential for rain to be talked about in the near future, BNPB will cooperate with DKI Province, later the implementation of BRIN and the Indonesian Air Force, budgeting from BNPB as well, we will carry out TMC. Later, hopefully, when heavy rains do not get disturbed in the New Year's process," said Suharyanto, Tuesday, December 27.

TMC is planned to anticipate extreme weather such as heavy rain accompanied by strong winds and lightning that has the potential to occur ahead of the turn of the year. In fact, it is predicted that Jakarta will flow heavy floods in the Jabodetabek area on December 28.

Meanwhile, on the other hand, it is certain that many people will move to celebrate the 2023 New Year.

Heru Budi revealed that the DKI Provincial Government also continues to dredge rivers and reservoirs to increase their water capacity so as to reduce the impact of flooding in residential areas.

"We do the dredging and dredging times. Hopefully, it doesn't come, that's the disaster to Jakarta," said Heru.

Then, Heru also appealed to companies to implement a work from home (WFH) system towards the end of this year. This appeal is expected to avoid congestion that often occurs after heavy rains and causes inundation.

"Later, maybe on December 30 to 2, we will appeal to the partial (January 2023). If there was a disaster, it could go through PPID, explain, condition each private employee to be able to WFH avoid congestion, disasters, waste, and others," explained Heru.

Previously, a researcher from the National Research and Innovation Agency (BRIN) revealed that there is the potential for large floods in the Jabodetabek area starting Wednesday, December 28, 2022.

"The potential for large floods is Jabodetabek. Whoever you live in Jabodetabek, and especially Tangerang or Banten, please prepare for extreme rain and catastrophic storms on December 28, 2022," said Climatology Researcher, at the Center for Climate Research, and Atmosfir, BRIN, Erma Yulihastin, in his Twitter account.

Erna menjelaskan, perkiraan tersebut berdasarkan analisis data dari Satellite Early Warning System (Sadewa). Badai akuat dari laut akan bergelanju ke darat melalui jalur barat dengan angin baratuan yang membawa hujan derai dari laut, dan dari utara melalui angin darat yang kuat.

"So Banten and Jakarta-Bekasi will be the central locations for the storm attacks. Starting from noon to night on December 28, 2022," he explained.

The overlap on land will be massive so that persistent rain on December 28, 2020 will spread. "Reaching other areas in western Java," he continued.

On that occasion, Erna explained about the vigilance regarding the sea and land "rain" that triggered flooding. The rain road in question is a storm that has been formed since Tuesday, December 27 at 03.00 WIB.

This Squall Line toll road that joins a meso-scale convective storm (MCC) and forms on land with a storm core above Banten and its surroundings. The rain toll road is a link to the supply of moisture from sea to land. At the same time it becomes a way for storms to cause flooding in Jabodetabek.

"This rain toll road is not only a liaison for the supply of continuous humidity from sea to land, but also a storm-like road to accumulate and transfer energy so that the storm formed can be long-lasting or last (more than six hours)," explained Erma.

"It can even experience multiplicities of energy when in the Sunda Strait. This mechanism can cause large floods in Jabodetabek, so we must be aware of it," he concluded.
