PEMBUATAN MAGNESIUM KARBONAT BERUKURAN ULTRA HALUS BAGIAN 1. PERILAKUKALSINASI DOLOMIT INDONESIA. Cadangan dolomite banyak terdapat di berbagai tempat di Indonesia.Cadangan terbesar terdapat di Provinsi Jawa Timur. Pada saat ini di Indonesia dolomit hanya dipergunakansebagai pupuk, walaupun sebenarnya dolomit dapat diproses untuk menghasilkan magnesium karbonatberukuran ultra halus yang biasanya digunakan sebagai bahan baku untuk obat dan sebagai filler dalam industrifarmasi dan industri cat. Dolomit mengandung 26,4% magnesium oksida dan 63,42% kalsium oksida. Kalsinasiadalah langkah pertama dari rangkaian proses untuk mendapatkan magnesium oksida atau magnesium karbonatdari dolomit. Pada penelitian ini, dolomit dari Madura telah dikalsinasi menggunakan tungku muffle. Reaksidekomposisi terjadi pada temperatur 730-890 oC. Variabel yang paling berpengaruh adalah temperatur danwaktu kalsinasi. Pada temperatur 600-700 oC, reaksi dekomposisi berjalan sangat lambat dan hasil kalsinasinyapun rendah. Tetapi pada temperatur 800 oC, hasil kalsinasi yang didapat sangat tinggi walaupun lajudekomposisinya masih rendah. Dan pada temperatur 900 oC dan temperatur di atasnya, laju dekomposisi danhasil kalsinasi mencapai maksimum. AbstractDolomite deposits can be found in many places in Indonesia. The larger deposit is located in East Javaprovence. Dolomite is mainly and recently used only as fertilizer, but it can be processed to obtain ultra finegrain magnesium carbonate that can be used as raw materials for drugs and fillers in pharmacy and coatingindustry. Dolomite contains 26,4% magnesium oxide and 63,42% calcium oxide. The calcination is the firstimportant step in obtaining magnesium oxide or magnesium carbonate from dolomite. In this recent research,dolomite from Madura has been calcined by using a muffle furnace. The decomposition reaction temperaturehas detected to take place at temperature range 730-890 oC. The most important variable in dolomitecalcination are temperature and time. At 600-700 oC, the decomposition rate is very slow and the result isvery poor. But at 800 oC, although the decomposition rate is still slow but the result is maximum. At 900 oCand beyond, the decomposition rate is very high and the result is maximum. The result is magnesium andcalcium oxide that is not bound chemically.

Manufacturing FTO (fluorine-doped tin oxide) is expected to replace ITO (indium tin oxide) because the process is simple and relatively low cost. Tin chloride precursor with fluorine doping is prepared via sol-gel method with a coating process with spray pyrolisis technique can be considered as a new breakthrough in DSSC device structures. This experiment uses the raw material tin (II) chloride hydrate (SnCl2.2H2O) as precursors and ammonium fluoride (NH4F) as a doping ratio of 6% wt with variation in temperatures of 250, 300, 350, 400 °C and time resistivities of 5, 20, 30 and 40 minutes. The results showed that the longer deposition time decreasing value of conductive glass resistivity. This condition would reduce the value of transmittance. High transmittance and low resistivity obtained on the variation of deposition time 5 minutes with a substrate temperature of 300 °C with a resistivity value of 3.16 x 10-4 Ω.cm and transmittance value of 86.74%AbstrakPembuatan FTO (flourine-doped tin oxide) ini diharapkan dapat menggantikan fungsi ITO (indium tin oxide) karena proses pembuatan yang sederhana dan biaya yang relatif rendah. Prekursor timah klorida dengan doping flourine yang dipreparasi melalui metode sol-gel dengan proses pelapisan dengan teknik spray pyrolisis dapat dipertimbangkan sebagai suatu terobosan baru di dalam struktur device sel surya tersensitasi zat pewarna. Percobaan ini menggunakan bahan baku timah (II) klorida hidrat (SnCl2.2H2O) sebagai prekursor dan amonium florida (NH4F) sebagai doping dengan rasio 6 %berat dengan variasi temperatur 250, 300, 350, 400 °C dan dengan variasi waktu 5, 20, 30, dan 40 menit. Hasil percobaan menunjukkan bahwa semakin lama waktu deposisi maka akan semakin kecil nilai resistivitas kaca konduktif. Namun semakin lama waktu deposisi akan mengurangi nilai transmitansi.

This study aims to report the findings of an investigation into the separation of lithium and magnesium ions in the artificial brine water. The artificial brine water contains concentrations of magnesium, calcium, and lithium cations that closely resemble the concentrations seen in natural brine water sourced from Gunung Panjang using magnesium chloride, calcium chloride, and lithium chloride p.a. The objective of this experiment was to investigate the impact of pH and the addition of sodium silicate on the separation of magnesium and calcium ions from lithium ions in artificial brine water. The best outcomes were achieved when the pH of the brine water was set at 10, and sodium silicate was added in a stoichiometric ratio of 219%. These parameters led to a lithium content of 90.06%, magnesium removal of 70.32%, and a Mg/Li ratio of 6.29, indicating a substantial presence of magnesium ions precipitated as solids with pyroxene (MgSiO3) phase. This research also succeeded in increasing the lithium content by 94.28% and reducing the Mg/Li ratio to 4.96 after the precipitated solids were subjected to a water-leaching process.

Transparent Conductive Oxide (TCO) is the main component for solar cell fabrication. One of the promising types of TCO is fluorine-doped tin oxide (FTO). The method used in depositing the conductive layer of FTO is spray pyrolysis with an ultrasonic nebulizer. The precursor is a local Indonesian product, dimethyl tin dichloride (DMTC), with doping ammonium fluoride (NH4F). The variable that used in this study were variations in deposition time (5. 10. 15. 20, and 25 minutes) with a fixed substrate temperature at 300°C and doping variations (un-doped, 2 wt.% doped and 8 wt.% doped) to see the effect of adding F doping to the precursor solution. The resistivity value with deposition time of 5. 10. 15. 20 and 25 minute (2 wt.% doped) is 0.218x100; 0.449x10-1; 1,567x10-2; 0.676x10-2 0.377x10-2 Ω.cm. For doping variations (un-doped, 2 wt% doped and 8 wt% doped) the value is 0.883x10-2; 0.377x10-2; 0.506x10-3 Ω.cm. There is a decreasing trend in the resistivity values obtained along with the increase in deposition time and the addition of doping to obtain better conductive properties. The grain size will increase with increasing deposition time and the addition of doping. The optimum resistivity value obtained in this study was 0.377x10-2 Ω.cm, obtained at the deposition time of 25 minutes with 2 wt.% doping.

Indonesia is one of the largest tin metal producers in the world, and one of its derivative products is tin chloride (SnCl4). This material has been used as a raw ingredient for the production of organotin compounds such as methyltin mercaptide for PVC (polyvinyl chloride) plastic industry as a heat stabilizer. On the other hand, this precursor can be used to synthesize SnO2 nanomaterials, which have other strategic potentials, including photocatalysts and solar cell applications. In this study, the synthesis of SnO2 nanocrystallites was carried out using a local tin chloride precursor via the co-precipitation method, followed by a calcination process at temperatures of 300, 400, 500, and 600 °C, for further usage as an ETL (electron transport layer) in a PSC (perovskite solar cell) device. The basic properties characterization was carried out using XRD (X-ray diffraction), ultraviolet-visible (UV-Vis) spectroscopy, and SEM (scanning electron microscopy), while the photocurrent-voltage (I-V) curve photovoltaic performance of the device was performed using a semiconductor parameter analyzer. The characterization results showed that increasing the calcination temperature from 300 to 600 °C increased the average crystallite size from 1.19 to 13.75 nm and decreased the band gap energy from 3.57 to 3.10 eV. The highest PCE (power conversion efficiency) was obtained from the device fabricated with SnO2 nanocrystallites calcined at a temperature of 300 °C, which was 0.0024%. This result was obtained due to the highest transmittance of this sample as compared to others; the higher the transmittance, the better the performance of the ETL, which in turn increased the overall efficiency of the PSC
