Abstract

Teknologi modifikasi cuaca sudah sering diaplikasikan di Indonesia terutama untukmeningkatkan jumlah curah hujan. Teknologi modifikasi cuaca diterapkan bila terjadiindikasi penurunan jumlah curah hujan dan kemungkinan akan munculnya fenomena ElNiño sebagai tindakan preventif. Aplikasi teknologi modifikasi cuaca yang dilaksanakan diDAS Citarum, Jawa Barat mulai tanggal 12 Maret s.d. 10 April 2001 adalah berdasarkan kenyataan bahwa inflow DAS Citarum menurun dengan drastis pada bulan Desember 2000 dan sebagai tindakan preventif akan munculnya fenomena El Niño pada akhir tahun 2001 atau 2002. Pada awal tahun 2001, tiga kaskade waduk di DAS Citarum mengalami defisit cadangan air sebanyak 486,36 juta m . Waduk Ir. Juanda yang merupakan waduk multi fungsi harus menyediakan pasokan air untuk: irigasi teknis pada lahan sawah seluas 296.000 ha (2 kali tanam), yang memberikan kontribusi sebesar ± 40 % ke Jabar atau setara dengan ± 10 % Nasional; air baku permukiman dan industri; serta penyediaan tenaga listrik (± 4,5 milyar kWh). Data akhir setelah dilaksanakan penerapan teknologi modifikasi cuaca dengan menggunakan konsep sistim dan lingkungan adalah nilai rata-rata aliran total Citarum sebesar 326,81 m /det dan volume total aliran Citarum sejak mulai kegiatan hingga tanggal 10 April 2001 adalah sebesar 847,1 juta m3.Weather modification technology has been applied in Indonesia especially to enhancerainfall. Weather modification technology has been employed whenever there has beenan indication of rainfall shortage and the possibility of El Niño occurrence asprecautionary action. Weather modification technology that was applied in Citarumcatchment area – West Java on 12 March – 10 April 2001 was based on the fact thatCitarum inflow decreased drastically in December 2000 and also as a preventiveendeavor to the possibility of warm episode in 2001/2002. In the early of 2001, threecascade dams had water storage deficit as much as 486.36 million m3. Ir. Juanda dam,which has multi purposes, has to supply water for: technical irrigation for 296,000 ha ofrice field (2 planting seasons) that contributes ± 40 % to West Java or about ± 10 % ofnational production; fresh water for community and industry; as well as electricity of about 4.5 billion kWh. After the application of weather modification technology by employing system and environment concept, it was recorded that the average inflow of Citarum catchment area was 326.81 m /sec and total volume during the activity was 847.1million m3.

Abstract

Sebuah studi tentang penggunaan garam serbuk polidispersi sebagai bahan semaitelah dilaksanakan dengan memakai model 1-dimensi. Dalam studi ini pengaruhpenambahan serbuk garam tersebut terhadap distribusi tetes awan dan jumlah penambahan presipitasi telah dilakukan, serta hasilnya telah dianalisa dan dibandingkan dengan hasil yang diperoleh pada pemakaian partikel higroskopis yang diperoleh dari flare piroteknik. Kondisi awan yang dipelajari terdiri dari beberapa macam ketinggian, updraft dan konsentrasi inti kondensasi atmosfer semula. Hasil studi menunjukkan bahwa bubuk garam polidisperse dapat dipakai untuk menghasilkan presipitasi dari awan marginal yang biasanya tidak mampu menghasilkan presipitasi.A study of use of polydisperse salt as seeding agent in cloud modification was conducted using 1-dimensional model. In this study the effects of introduction of the salt powder to cloud droplet distribution and the amount of precipitation enhancement were analyzed and compared to the results obtained by introduction of hygroscopic particles from pyrotechnic flares at various cloud media conditions such as cloud thickness, updraft, and original atmospheric condensation nuclei. This study reveals that polydisperse salt powder is usable to obtain precipitation from marginal cloud that usually can not produce precipitation.

Abstract

During the dry season there was potential for forest and land fires and the water supply in the reservoir was reduced, including electricity & agriculture. An effort made by Government (1976-2020), was TMC (weather modification technology) which used aircraft and chemicals. Many roads lead to Rome, including Anion-based TMC and solar power. TMC Anion in Indonesia is still being studied, but in several countries it has entered the operational and commercial phases and can compete with the provision of clean water with other technologies. TMC studies and experiences in Australia, Oman, Jordan, as well as Germany, Switzerland and Russia. TMC is very prospect applied in Indonesia, also very economical. In addition, smoke as Karhutla particles is a problem, both visibility and ISPA disease, with TMC Anions smoke can be modified into CCN and finally into clouds and rain, so that Karhutla can be reduced and water supply can be fulfilled.
