Abstract

In recent years, the development of renewable energy such as biodiesel has been widely researched throughout the world as technology advances in the era of Industry 4.0. At the final station of biodiesel production in the maturation tank, the by-products will form by-products in the form of sterol glycosides in Fatty Acid Methyl Esters which have not been utilized. This study aims to determine the volume of biodiesel from a mixture of sterol glycosides with a ratio of 0.5% H2SO4 catalyst concentration; 1%; 1.5% and 2% and tested their characteristics in accordance with the Indonesian National Standard (SNI 7182: 2015). Biodiesel production was carried out by esterification with a molar ratio of 1:6 (sterol glycoside: methanol) to variations in H2SO4 catalyst concentration. The results of the highest yield volume biodiesel were obtained from a catalyst concentration of 1.5% of 28.02% and the lowest yield of 17.50% in a 0.5% catalyst. Based on the characteristic test of biodiesel by varying the concentration of catalyst H2SO4 obtained density of 852 – 862 kg m-3, viscosity of 4.642 – 4.950 mm2 s-1 and saponification number of 191.007 – 198.164 mg-KOH g-1 according to standard characteristics SNI 7182:2015, while for the water content of 0.1965 – 0.1976% and acid numbers of 2.151 – 3.232 mg-KOH g-1 isn’t according to standard characteristics. Based on research, pre-treatment treatments was recommended before the refining process to reduce the amount of acid and moisture content so according to standard characteristics.

Abstract

Bioethanol is one of the biofuels that is present as an alternative fuel that is more environmentally friendly and renewable. This study aims to determine the effect of good temperatures in the process of hydrolysis for the manufacture of bioethanol, the effect of operating conditions for 5 days of good fermentation to produce large bioethanol and bioethanol levels produced by fermentation of banana kepok skin using yeast bread (Fermipan) and tape yeast, from both yeast to fermentation, which ones produce more bioethanol. This study of banana kepok peel dried into a powder. Banana skin powder was tested by FTIR, SEM, and XRD. The hydrolysis process with 0.5 N sulfuric acid in 500 mL with 25 grams of banana kepok peel powder. The hydrolysis process with temperature variations of 60ºC, 80ºC, and 100ºC. The hydrolysis solution is fermented with yeast variations, namely Fermipan and yeast tape (4 grams, 8 grams, and 12 grams) with the addition of NPK 4 grams and 5 gram urea. Results glucose levels were obtained at 60ºC, namely 33.0%, at 80ºC, 41.2% and temperatures of 100ºC, 56.0%. The results of fermentation solutions obtained by the concentration of ethanol in Fermipan with a weight of 4 grams, 8 grams and 12 grams respectively 0.264%, 0.630% and 0.786% while the concentration of ethanol in the tape yeast weighs 4 grams, 8 grams, and 12 grams successively which are 0.015%, 0.006% and 0.017%.
