Abstract

The electrical characteristics of filtered seawater can be determined by using Cu-Zn electrode pairs. Seawater is filtered by using a 1 micron sediment filter. Measurement of electrical characteristics of water is carried out using a 3 watt DC LED load and when the load is removed. The electrolyte cell consists of 40 cells, which are arranged in series and parallel with 300 ml per cell. Tool testing is carried out for 144 hours with 6 times electrolyte filling every 24 hours. The test results show that the longer the tool is used, the more electrical characteristics produced will be decreasing. The produce of maximum voltage (Vbl) by seawater is not filtered with a series of 31.5 V. The produce of maximum power (P) by seawater is not filtered with a series of 101.1 mW. The produce of maximum illumination by seawater is not filtered with a series of 426.4 Lux, the duration of the light is 8 hours. Despite the produce of maximum illumination by filtered seawater with a series of 319.7 Lux series, the duration of the light is 11 hours.

Abstract

The measurement of peak ground acceleration and ground vulnerability index in Lampung area has been done. This study aims to analyze the acceleration of ground vibration and ground vulnerability index with soil types namely, entisol, inceptisol and ultisol. The tool used to perform the measurement is the vibration meter VB-8213. The results of the analysis show that changes in the acceleration value of ground vibration and ground vulnerability have the same pattern of change with distance. The further distance to the vibration source the acceleration value of ground vibration and ground vulnerability index will be smaller. The greatest vibration acceleration value is found in ultisole and inceptisol soil type. The smallest vibration acceleration value of the soil type is entisol. While the value of ground vulnerability index for all types of soil entisol, inceptisol and ultisol have relatively small ground vulnerability index.

Abstract

Hydrogen adsorption has been simulated on carbon nanotubes for optimum hydrogen absorption. Parameters that affect the amount of hydrogen absorbed have been studied, such as the effect of chirality and temperature on hydrogen absorption in CNTs. The simulation method of hydrogen adsorption on carbone nanotubes uses molecular dynamics simulation code LAMMPS, applies Lennard-Jones interatomic potential and hydrogen atom movement using Van Der Waals force with Microcanonical Ensemble. Data analysis is the output of LAMPS in the form of data in XYZ format. The data contains information in the form of integration steps, number of atoms, temperature, pressure, potential energy, kinetic energy, volume, van der Waals energy, total simulation time and hydrogen absorption. The simulation results show that the optimum absorption occurs at run 10000 and a temperature of 100 K, for armchair chirality of 10 atoms, chirality of 12 atoms and zigzag chrality of 5 atoms. Formation of hydrogen coordinates with Avogadro software, formation of CNT coordinates with VMD software and visualization of hydrogen adsorption on CNTs using VMD software.

Abstract

The electrical characteristics of cassava peel and cassava can be determined by using a pair of electrode copper (Cu) and zinc (Zn). The measurement of the electrical characteristics of cassava peel had been done using a 5 watt LED load and when the load is released. Cassava peel and cassava are used without fermentation and with fermentation. Electrolyte cell that used consists of 20 cells, which were arranged in series and parallel, with volume + 200 ml for one cell. The maximum power generated cassava peel 5.8597 mW, and 14.1052 mW on cassava. Zn2 electrode (zinc battery used) produces a larger power, which is 5.8597 mW compared with Zn1 (ordinary zinc) is 1.9902 mW. Cassava peel without fermentation produces a larger voltage of 20.76 volts, compared with cassava peel 19.17 volts of fermentation. In cassava peel, circuit cell power in series a larger of 5.8597 volts, compared with circuit power in parallel is 5.7078 volts
