Abstract

Indonesia is a country that has a vast ocean or water area. This makes Indonesia very potential for developing electricity generation using ocean wave energy. The potential and kinetic energy in ocean waves can be a great opportunity to convert it into electrical energy. There are several ways to utilize ocean wave energy, one of which is by using an Oscillating Water Column Ocean Wave Power Plant (PLTGL-OWC). In general, the performance of PLTGL OWC depends on the characteristics of the water waves entering the OWC oscillating column. Therefore, the aim of this research is to determine the influence of the characteristics of the water waves produced on the performance of the PLTGL OWC prototype using experimental methods and varying water surface heights of 20 cm, 25cm and 30cm. From the results of the research that has been carried out, the prototype performance obtained at each water level has an OWC column efficiency value of 0.072%, 0.063% and 0.022%. Meanwhile, the largest voltage and current produced by the PLTGL OWC prototype was 5.4 Volts and 13.53 mA.

Abstract

In line with development, human daily activities are very dependent on electrical technology so that its fulfillment needs to be paid close attention. Given this, the use of mini type power plants or generators is very necessary, especially when the main supply from PLN experiences disruption. Apart from that, currently almost all electrical energy supplies still depend on the use of fossil energy sources which, if used continuously, will cause their availability to decrease and the effects of environmental pollution from the combustion process. To prevent this from happening, efforts are needed to increase the efficiency of using machines that consume fossil fuels and reduce the effects of environmental pollution due to exhaust emissions. Therefore, the aim of this research is to determine the effect of adding an alumina catalyst on exhaust emissions and fuel consumption in engines using experimental methods with load variations of 0 Watt, 250 Watt, 500 Watt and 750 Watt. From the research results, after mixing the catalyst and fuel, it was found that the concentration of CO, CO2, O2 and H2S exhaust gas emissions decreased and fuel consumption could also be reduced from 100% to 66% at a load condition of 750 Watts.
