JAKARTA - The government has prepared a scheme for seeding salt in the air to break the growth of rain clouds to suppress extreme weather which is expected to occur in Jabodetabek tomorrow, Wednesday, December 28.

The potential for extreme weather to severe storms is based on the research presentation of the National Research and Innovation Agency (BRIN) Erma Yulihastin.

"With a competition pattern, burning salt seeded materials can disrupt cloud growth. This is done by adding to the core of condensation," said Head of the DKI Jakarta Regional Disaster Management Agency (BPBD), Isnawa Adji in Jakarta, Tuesday, December 27, confiscated by Antara.

According to him, the seeding of salt is one of the schemes in weather modification techniques (TMC).

In addition to the seeding of salt, he continued, the second technique is to make rain cloud premats to prevent entry into the Jakarta area so that it becomes cloudy and the rain that occurs is just drizzling.

BPBD DKI Jakarta has coordinated with Air Wings 1 Air Squadron 2 TNI AU, BRIN, and the National Disaster Management Agency (BNPB) at Halim Perdanakusuma Air Base, East Jakarta, Tuesday 27 December.

From the results of this coordination, the Indonesian Air Force, he said, prepared several types of aircraft, including CN-212 aircraft which can carry 800 kilograms of salt seeded materials with a spreading technique carried out manually.

Meanwhile, the Cassa aircraft can load 2.4 tons of salt which takes two hours to prepare the salt into the consul form and the type of Hercules aircraft can load a minimum of 5 tons of seasoning material.

Isnawa added that TMC will only be effective from the morning to around 17.00 WIB, with effective results that will occur in the next 4-15 hours.

Even so, TMC can only be implemented in Jakarta if there is already an emergency alert status determined by the regional head.

"Against this, BNPB stated its readiness to carry out TMC assisted by the Indonesian Air Force, BRIN and BMKG," he said.

Meanwhile, the DKI Jakarta BPBD has implemented a standby for potential hydrometeorological disasters by making a number of efforts, including the distribution of facilities and infrastructure to support flood management in every flood-prone village.

In addition, ensuring the readiness of disaster alert posts and evacuation locations along with supporting equipment at the administrative, sub-district and sub-district levels to be alert and activated when a disaster occurs.

In addition, his party has alerted 267 disaster management/TRC personnel in all urban villages in Jakarta as an effort to accelerate disaster coordination and handling.

Previously, BRIN climatologist Erma Yulihastin through her Twitter account, @EYulihastin, said that there would be extreme rain until a devastating storm hit Jabodetabek.

This is based on data he compiled from the satellite-based disaster early warning system, Sadives.

"Whoever you live in Jabodetabek and especially Tangerang or Banten, please prepare for extreme rain and catastrophic storms on December 28, 2022," wrote Erma.

He said storms from the sea would move to land by two routes, namely from the west through the westerly wind that brought rain from the sea and from the north through strong surface winds.

From the early warning system, he studied that the Banten and Jakarta and Bekasi areas would be the central locations for the storm, which is expected to start from noon to night on December 28, 2022.
