Jakarta: Operations using weather modification technology (TMC) ends Sunday, January 12, 2020. A total of 57.6 tons of salt is used to unravel the potential carrier clouds of heavy rain.
 
"(Monday) January 13 2020 until today there has been no operations because the air is good enough. There are no significant clouds that bring heavy rain," Chairman of the Agency for the Assessment and Application of Technology (BPPT) Hammam Riza told Medcom.id on Friday January 17, 2020.
 
According to him, during the operation, they used two planes belonging to the Indonesian Air Force (AU), a CN 295 and a CASA 212. There were 34 flights in total, 19 times using CN 295 and 15 times Casa 212.

"Every day there are usually 2 sorties using the CN 295 and 2 sorties using the CASA 212. The total flying time has been 74 hours and 15 minutes," said Riza.
 
Riza explained that the budget spent on 6.2 tons of material per day is around IDR 60 million. The total budget that came out during the TMC operations has reached IDR 600 million.
 
"As for the aircraft budget, it is taken from the Air Force’s budget," said Riza.
 
BPPT, he said, had not planned to seed salt in Jakarta, Bogor, Depok, Tangerang and Bekasi for some time to come. Because the potential for heavy rain-carrying clouds has been reduced.
 
"We will just see the change in weather conditions every day. If there are data from the Meteorology, Climatology and Geophysics Agency (BMKG) which later shows the potential for extreme weather, then later we will do TMC operations again," added Riza.
 
TMC operations was taken as an effort to mitigate heavy rains by sowing salt in the clouds that could potentially enter the Greater Jakarta Area and cause heavy rains. Operations have been carried out around the Sunda Strait area since Friday, 3 January 2020.
 
This operation involves a number of institutions. BPPT cooperates with BMKG, National Disaster Mitigation Agency (BNPB), and the Air Force.
