Abstract

The declining petroleum production in Indonesia requires the alternative ofrenewable energy and be more eco- friendly, so it needs more flexible alternative energy. Oneof them is the energy gained from oxyhydrogen gas (Brown Gas). Oxyhydrogen gas can beobtained by breaking down the water molecule (H2O) with the help of electrical energy orcommonly called an electrolisys process. In this study, used oxyhydrogen dry cell generatorstype with 316L stainless steel electrode material consisting of 6 cells with the variation of theKOH catalysts 50, 60, 70, 80, and 90 grams per 1 liter aquadest. The characteristics of theoxyhydrogen generator performance testing are obtained, power consumption, oxyhydrogen gasproduction rate, and oxyhydrogen generator efficiency. From the results of studies that havebeen conducted, it is possible to know that increasing the concentration of KOH catalysts leadsto increased power consumption. The highest electrical energy consumption is 38,94 Watt at theconcentration of the KOH catalyst 90 gr/l and the lowest electrical energy consumption is 21,25Watt at the concentration of the KOH Catalyst 50 gr/l. Then the rate of oxyhydrogen gasproduction is increasing with increasingly high concentrations of KOH catalysts. The highestoxyhydrogen gas production is 9,045e-7 kg/s at the concentration of the 90 gr/l KOH catalystand the lowest oxyhydrogen gas production is 4,522e-7 kg/s at the concentration of the KOHCatalyst 50 gr/L. So the highest oxyhydrogen generator efficiency is 54,76% at the 70 gr/lconcentration of the KOH catalyst.

Abstract

Biogas is a gas produced from the fermentation process of organic materials bymicroorganisms in closed conditions (anaerobic). Biogas consists of ± 60% CH4 (methane), ±38% CO2 (carbon dioxide), ± 2% N2 (nitrogen), O2 (Oxygen), H2 (hydrogen), and H2S(hydrogen sulfide). In this research, the making of biogas uses raw materials from cow dung.Cow dung is the right raw material because it contains methane-producing bacteria. Thisresearch aims to determine the influence of the EM4 addition of biogas quality produced. Thisresearch was conducted in the Basic laboratory system of energy generation of the SurabayaState Polytechnic electronics. The method of the research is to use a comparison of cow andwater in raw materials, with a ratio of 1:1 with the addition of EM4 (Effective microorganism)as much as 3 liters on variations of 1 and 1.5 liters on variation 2. Biogas making is carried outon the digester with a volume of 200 liters with a batch system with stirring 3 times a day withfermentation for 25 days. The result of this research is with the addition of EM4 as much as 3liters produce biogas with methane gas content with the amount of 53.6%. The resulting biogascombustion test has a yellowish blue flame, a long flame of 56 seconds. While the addition ofEM4 with a total of 1.5 liters produces biogas with methane gas content with the amount of46.8% yellow flame color with a long flame of fire for 34 seconds
