Abstract

Spark plugs are the most important thing in the combustion system. Spark plugs in internal combustion using gasoline significantly affect vehicle performance. Likewise, fuel use must follow the compression ratio in the combustion chamber. The purpose of this study was to obtain the effect of differences in hot, cold, and medium spark plugs on engine performance and also the effect of fuel differences in supporting the performance of pertalite and pertamax two-wheeled vehicles in supporting the performance of 135 CC two-wheeled four-stroke vehicles in 2009. The result with hot spark plugs will maximizer-pm, increasing torque and power with pertalite fuel—the effectiveness of increasing power by 31%.

Abstract

Hydrogen energy is one of the alternative energies that will help overcome the scarcity of fossil energy. One of the steps to produce hydrogen energy is by the electrolysis method. In this study, the electrolysis process was carried out with a combination of peat water and coconut water. Given that in the South Kalimantan area the existence of peat land is very extensive and there are also many coconut trees. So the main raw materials used can be renewed. In addition, the composition contained in peat water can also help in the electrolysis process which consists of metal minerals such as Na, Mg, Al, Fe, Ca, K, and others. These mineral compounds will also help in accelerating the formation of hydrogen gas. The mineral compounds contained in coconut water and peat indirectly produce electrolyte properties and can be used as catalysts to accelerate the reaction to produce hydrogen gas by the electrolysis method. From the results of the research conducted, as much as 155 ml of hydrogen was produced. Hydrogen gas production, 0.6 A of electric current, and 7.3 Watts of electric power in the 30-minute electrolysis process were found in sample F (1.5 L of pure coconut water). In the electrolysis process, peat water and coconut water, the voltage used during the electrolysis process was 12 V which flowed through the cathode and anode.
