Abstract

Biogas is an alternative energy source that could solve two problems at once, the problem of environmentally friendly energy needs and the problem of waste treatment. One of the sources of biogas is obtained from anaerobic bacterial fermentation of cow dung waste. The biogas fermentation process produces impurities such as carbon dioxide (CO2) as a combustion inhibitor. Carbon dioxide will inhibit the combustion reaction, resulting in incomplete combustion. The biogas purification process is needed to reduce the amount of carbon dioxide in the biogas. The purification process is carried out using an absorbent compound of calcium oxide (CaO) to bind carbon dioxide contained in the biogas. Thus, the purpose of this study was to analyze the effect of the biogas purification process using calcium oxide on the characteristics of the diffusion flame produced by combustion. The research was conducted experimentally using the physicochemical-absorption method of purification by flowing biogas through a purificator device that contained a purification solution. After passing through the purification solution, the biogas was regulated at a fuel flow rate of 3 liters/min and then proceed to the bunsen burner. The results showed that purification affected increasing the characteristics of the diffusion flame combustion due to the reduced amount of carbon dioxide in the biogas. This is indicated by increasing the purification molarity, it also increases the flame speed of combustion and the flame angle, as well as a decrease in the flame height.

Abstract

Used cooking oil is a waste product with great potential as a raw material for biodiesel production through transesterification. This study was conducted to determine the effect of transesterification reaction temperature on biodiesel yield and quality. The biodiesel production process includes a degumming step to remove gums by adding 1% H₃PO₄. This is then followed by transesterification using 1% NaOH as the catalyst, an oil-to-methanol ratio of 1:0.5, a stirring speed of 300 rpm, and a reaction time of 60 minutes. The transesterification reaction temperatures were 40°C, 50°C, 60°C, and 70°C. The results showed that the reaction temperature significantly affected the yield and physical quality of biodiesel. The highest yield was 85.85% at 40°C, while the lowest was 80.37% at 70°C. The maximum viscosity was observed at 60°C (6.0 cSt), and the minimum at 70°C (5.71 cSt). The highest density was 0.8620 g/mL at 50 °C, and the lowest was 0.8607 g/mL at 40 °C. The highest flash point was 40°C at 173.27°C, and the lowest was 70°C at 164.97°C. The results showed that the biodiesel produced met the quality standards of SNI 7182:2015, thus supporting its suitability as an alternative fuel derived from used cooking oil.
