Abstract

Along with the development of nanotechnology, the development of solar cells entered a significant stage with the emergence of the newest generation, namely DSSC (Dye Sensitized Solar Cell). The utilization of dragon fruit skin which has been extracted as dye in dye sensitized solar cells and solar cell development to realize sustainable energy supply is the main target in this study. The method carried out begins with the synthesis of nanoparticles from organic material (TiO2), to obtain good TiO2 material as an anti-reflection, where anti-reflection is selected on DSSC technology to reduce light reflection in the visible light region. The crystal size of TiO2 was analyzed as an oxide layer material in DSSC. DSSC synthesis was carried out and the parameters of organic solar cell devices (DSSC) were optimized to obtain solar cells with good conversion efficiency. The results showed that the size of TiO2 obtained was an average of 0.211 nm and the maximum wavelength value of the extract of the dragon fruit dye solution was 530 nm. Keywords: dye, solar cell, DSSC, TiO2.

Abstract

The presence of geothermal manifestation such as Terak hot spring near granite massive bodies on Bangka Island raises an importatnt question about the subsurface characteristics of a potential radiogenic system. As traditional geothermal system in Indonesia is well known, research must now focus on understanding the radiogenic system, especially on the subsurface information. This study addresses the local magnetic susceptibility of Terak subsurface hot spring by performing magnetic method. The integration of 2D to 3D magnetic data, field observations and geological information show high susceptibility data (>0.005 SI) which are indicated as granite intrusion which act as the heat source. A central zone of lower susceptibility (<0.005 SI) displays a distinct pattern, interpreted as a fracture zone as the hydrothermal fluid pathways. The identification of recharge area further supports the interpretation of an active hydrothermal system. The result of this study are in good agreement with the geological framework of the region and contribute to a better understanding of radiogenic geothermal systems in Indonesia.
