| Abstrak | Weather modification in Indonesia was done by weather modification technical operating unit (UPT-HB) belong to BPPT, from the beginning for cloud seeding method they use salt powder (NaCl). The mechanism powder on the cloud act as Ultra Giant Nuclei (UGN) in collision coalescence process, rather than act as cloud condensation nuclei (CCN). The application of cloud seeding flare method since less than one decade in Indonesia had shown many advantages, the most significant feature for instance 1 kg of flare equal 1 ton of salt powder. This advantages had gave many impact for weather modification operation such more efficient, more economic, easier handling especially when stock in warehouse after flare were made. The aim of the research that had been funding by incentive research the ministry of research, was planed to support (UPT-HB) in term of making the supply material component needed for making flare from local sources. In the year 2007 UPT-HB has declared will change powder method to Cloud Seeding Flare method. The research activity had been planning for 3 years period of time , period 1(first year) activity is laboratory experiment for MgO extraction from dolomite - CaMg(CO3)2, period 2(second years) activity is laboratory experiment extraction Mg from MgO, and period 3 (third year) activity is up scaling the result of period 2 (home industry scale) to produce Mg and market study to fulfill local demand . Recently (in 2008) activity for period 1(first year) had been done, from laboratory experiment MgO with 97% purity had been separated from dolomite CaMg(CO3)2 . This research was application of technology process in order to get Mg metal from dolomite by decomposition treatment , hydrometallurgy process, carbonization reaction, settling the solution then MgO was got as hydromagnesite after the dryer via the green house. |
