The Indonesian government plans to use artificial rain to overcome the growing disasters caused by forest and land fires in the country.
According to the Plt report. Head of the Public Relations Information and Data Center of the National Agency for Disaster Management (BNPB), Agus Wibowo, at this moment the thick mist of forest and land fires is an inhibitory factor in the evaporation process as a condition for cloud formation The smoke in addition to retaining water near the surface, prevents the sun's rays from entering the earth, making evaporation difficult.
According to the observations of the Meteorology Agency of Climatology and Geophysics (BMKG), the potential necessary to generate condensation is not yet reached, considering that the sowing of salt (NaCl) as a condition for producing artificial rain, requires that clouds reach at least 80% of normal conditions for precipitation.
In this regard, the BNPB collaborates with the Agency for Technology Evaluation and Application (BPPT) and with the BMKG to apply the new technologies in an effort to clear the smoke caused by forest and land fires using calcium oxide or lime active (CaO), which is exothermic.
The director of the BPPT Meteorological Modification Technology Center, Tri Handoko Seto, explained that lime will be sprayed on clouds of smoke, where it will break down its particles. As a result, the smoke will dissipate and solar radiation can penetrate the earth's surface, causing the necessary evaporation. This is expected to form enough clouds so that salt can spread over and generate artificial rain.
BPPT itself has prepared 40 tons of active lime and has alerted the cargo to the Halim Perdanakusuma Air Force Base in eastern Jakarta. After receiving instructions, the BPPT teams will take the lime to the provinces most affected by smoke from fires, such as Central Kalimantan, West Kalimantan, South Kalimantan, Riau, Jambi and South Sumatra.
To sprinkle the lime, the BPPT will use three types of aircraft, Cassa 212 with a capacity of 800 kilograms, the CN 295 with a capacity of 2.4 tons, Hercules C130 with a capacity of 4-5 tons.
Previously, BNPB Chief Doni Monardo emphasized that the problem of forest and land fires can not only be managed through the use of land and air cuts. The solution to overcome this disaster is the rain. The BMKG has predicted that the new rainy season will enter in mid-October, therefore, artificial rain must be done immediately to overcome the problem.
