Synergy with BRIN, City Spraying Water Mist at City Hall Building

The Jakarta Provincial Government is making various efforts to overcome the decline in air quality. One of them is to use a water mist generator made by the National Research and Innovation Agency (BRIN). This effort is a pilot project whose trials carried out at the Environment and Forestry Ministry (KLHK)'s initiation supported by PT Pertamina on August 27 at the Pertamina Head Office Building, Central Jakarta.

This technology was actually tested in 2019

Pollution and Environmental Damage Control Division Head, Erni Pelita Fitratunnisa said based on research results, this effort can reduce PM 2.5 levels around the test area. PM 2.5 itself is a type of particle, which is the reference for being measured by all countries with high air pollution in the world.

"This technology was actually tested in 2019. Well, according to information from BRIN, this operation is twice a day, with a duration of each session of four hours and a time gap between sessions of 30 minutes to 1 hour," she expressed, in the Jakarta Provincial Government's press release, Friday (9/1).

Vehicles Failing Emissions Tests May Not Enter North Jakarta Mayor's Office

He explained there were no other ingredients in the sprayed water. As much as 5-10 liters of water per minute is sprayed by a device mounted on a tall building. The provision of spraying equipment is currently being pursued by BRIN with many requests from various parties.

She expected the availability of high-rise buildings in Jakarta, both government offices, such as the mayor's office, public and regional hospitals, to private offices that have rooftops and allow them to do the same thing

"Another hope is the role of private or commercial buildings, especially in the Sudirman and Thamrin areas," she added.

He went on to say that the efforts being made would be further evaluated. If it was effective in reducing pollutant concentrations, spraying with the water mist method would be continued. However, there were several criteria that officers should meet to apply this method. One of them was that the building must have a height of more than 20 meters and less than 200 meters.

"If it is less than 20 meters, it isn't effective in absorbing pollutants or dispersing pollutants that pollute the air environment. If it is more than 200 meters, it must be studied, another trial is carried out, it seems that this has never been done so what is currently being carried out is the 20-200 meter range," she stated.
