- Research on renewable energy has become an interesting topic in the era towards industry 5.0. This was because the world's energy needs continue to increase every year, especially during the industrial revolution. The use of biodiesel as an alternative fuel began to be developed along with the emergence of policies for adding biofuels to fossil fuels. Kepuh oil has the opportunity to be developed as an alternative fuel as biodiesel feedstock. This was because kepuh oil contains triglycerides. The purpose of this study was to determine the effect of catalyst concentration on density, viscosity and heating value. The catalyst used to produce biodiesel was KOH. The concentration of the catalyst used was K-0.8%; K-0.9%; K-1.0%; K-1.1% and K-1.2%. Biodiesel production was carried out at atemperature of 600C for 1 hour in the esterification and transesterification processes at the same temperature and time. The best production of kepuh biodiesel was obtained at acatalyst concentration of K-0.8% with a density value of 0.83 gr/ml, a viscosity of 2.8 cstand a heating value of 9,847 cal/gr, while the best results were obtained from mixing purediesel with kepuh biodiesel at a catalyst concentration K-0.8%. The test resulted in adensity value of 0.82 gr/ml, a viscosity of 2.24 cst, and a heating value of 10,658 cal/gr. Thehighest yield was 77.3% at 1.2% catalyst concentration
- Research on renewable fuel energy sources and the use of catalysts in increasing their production has always been an interesting topic in this era towards industry 5.0. This is because the world's energy needs are always increasing every year, especially during the industrial revolution. It requires more sources and other types of energy to convert. Based on that need, alternative energy sources that are renewable and abundant were always needed. One form of renewable alternative energy source is biodiesel. Biodiesel is environmentally friendly, clean, biodegradable, and produces low exhaust emissions. One of the raw materials for biodiesel can be obtained from Kepuh seeds (Sterculia foetida). The manufacture of biodiesel goes through five stages, namely pressing, degumming, esterification, transesterification, and purification. Then, the biodiesel that has been produced is added to bio solar in a ratio of 8:2 (biodiesel: bio solar). Additions were made to five samples of the fuel mixture based on the amount of catalyst used (0.8; 0.9; 1.0; 1.1; 1.2%). Based on the results of the biodiesel quality test, the average value for the density test was 0.85 kg/m3, the viscosity was 3.24 CST and the calorific value was 11,090 cal/gram.
