Sensitizer or dye organic for sensitizing TiO2 nanocrystalline solar cells is intended as an alternative photovoltaics to silicon-based renewable. The use of silicon materials that are not environmentally friendly is one reason for the development of sensitizers or dyes organic to sensitize TiO2 nanocrystalline solar cells as an alternative to photovoltaic. The dye used in this study came from …
This study aims to analyze the level of noise and mechanical vibrations in the rice mill room received by the operator when operating the machine. The results of the measurement of the noise at a height of 150 cm on the first floor obtained the lowest noise level of 83.9 dB and the highest noise level of 101.3 dB. . At a height of 120 cm the lowest noise value is 84.2 dB and the highest noise v…
