Purification of silica sand volcanic Mount Merapi has been done, for raw material photovoltaic. Leaching purification process is done using aqua regia solution, H2SO4, and HCl. Purification of silica sand of Mount Merapi as a raw material photovoltaic assumes that photovoltaic technologies that utilize solar energy is quite affordable, do not run out, and clean so that it will provide long term benefits are substantial. Stage purification process through grinding up to size 60 mesh, iron using magnetic separation, leaching of acid and alkaline leaching. Characterization of the samples using XRD and XRF. The result showed that Mount Merapi volcanic sand containing silica is high at 48-50%. XRD characterization results indicate that the silica in sand samples well as silicon dioxide or mineral has amorphous structure. Among aqua regia, H2SO4 and HCl leaching that has the ability to nicest namely the concentration of concentrated HCl and purified silica has a purity of 59%. Keywords: purification, silica, volcano sand

Five medicinal forest plants are potential candidates to be developed as cholesterol-reducing herbal product. The objective of this research is to explore the potency of the leaf of pulai ((Alstonia scholaris, R.Br), jabon merah (Antocephalus macrophyllus), jati belanda (Guazuma ulmifolia), mindi (Melia azedarach), and surian (Toona sinensis) based on their main secondary metabolic contents and to study their activity as HMG-CoA reductase inhibitor, an enzyme key in the regulation of cholesterol biosynthesis. Dried leaves materials were prepared from the each plant by standard procedure and their pythochemicals contents were determined qualitatively. Subsequently, flavonoid fractions from the leaves of all five plants were prepared, and alkaloid fraction was prepared from the leaf of pulai only. The flavonoid content was determined using quercetin as standard. The effect of each samples on the HMG-CoA reductase activity were analyzed using HMGR in vitro assay kit. At concentration of 20 ppm jati belanda leaf extract, however, showed the highest inhibitory activity which was similar to quercetin (5 ppm) as well as pravastatin control inhibitor. Further analysis showed that extracts from leaves of all plants tested were shown to inhibit the HMG-CoA reductase with IC50 values ranging from 7.53 to 52.62 ppm.Keywords: HMG-KoA reductase inhibitor, in vitro assay, medicinal forest plant exploration
