Siborongborong (6/5) - PT Indonesia Asahan Aluminium (Persero) or INALUM in collaboration with the Agency for the Assessment and Application of Technology (BPPT) implemented a weather modification program as a form of participation in Lake Toba conservation programs, one of which is increasing the water flow of Lake Toba.
INALUM Managing Director, Sophia Isabella Wattimena, said "INALUM is committed to supporting Lake Toba conservation programs. The environmental ecosystem of Lake Toba needs to be maintained to ensure its sustainability. This area is a source of welfare for the people around the lake and along the Asahan river "
Weather Modification Technology (TMC) is a method that has been used in various countries to increase rainfall. Based on empirical research in various countries, this technology can increase rainfall by 20-30%.
The Inalum and BPPT team carried out the inaugural flight operation on April 1, 2021 to April 29, 2021 around the Lake Toba catchment area with 27 cloud seeding flights and spent 169 CoSAT flare seedlings.
The implementation of this first period program has succeeded in increasing the water level of Lake Toba by 8.5 CM and increasing the rainfall by 36.3 percent. "INALUM is ready to support the implementation of the second period of TMC in September 2021. The company will coordinate with the Regional Government of North Sumatra regarding the use of low explosive flare seedlings for this activity." Sophia said.
The opening ceremony of the Implementation of Weather Modification Technology (TMC) was carried out by the Executive Director of INALUM and the Head of BBTMC BPPT in Siborongborong, North Sumatra on March 29, 2021. INALUM pays full attention to the implementation of this program. The company allocates special personnel, financial needs and cooperation with BPPT.
As one of the strategic areas to support life, the Lake Toba area has become an aspect of sustainability that INALUM has paid attention to. Apart from TMC, in the environmental conservation sector, the Company has planted 440 thousand trees in a 750 hectare Catchment Area (DTA) from 2015 to 2020. This effort is to preserve the Toba fund as the largest tourism icon in North Sumatra.
