An alternative energy source that can be used is biodiesel. Used cooking oil as the basis of biodiesel because of its abundant availability and is considered a waste that is not useful. Intemperate utilize of biodiesel has issues in long-term engine execution in consequence of the high viscosity of biodiesel and moo volatility, it also affects the fuel droplet size and poor fuel atomization. Butanol has a higher cetane value. lower latent heat value as well as lower viscosity value consequently reduce exhaust emissions better. The results of the research showed that the physicochemical properties of the fuel in the form of compound B100 components, namely methyl oleate with a peak area of 60.22%, functional groups in the form of alkenes, aromatics, ethers. The highest density is B20 biodiesel with a esteem of 0.8 kg/L. The highest viscosity is at B20 with a value of 5.5875 cSt. The highest flash point by sample B20 is 98. The highest calorific value is at D100 with a value of 10745.8551 kcal/kg. The performance of the diesel engine is in the form of torque with the highest value of D100 with 8.9 Nm at 1000 rpm. Maximum power by B10nbu10 with a value of 16.4852 PS at 1400 rpm. The smallest fuel consumption is sample B20nbu20 with a value of 2.4523 kg/hour at 1000 rpm. The greatest thermal efficiency is owned by B10nbu10 with a value of 41.5218% at 1400 rpm. The highest smoke opacity by D100 1000 rpm with an opacity value of about 82%. The lowest smoke opacity value is B20nbu20 2200 rpm with a value of 4%. © 2024 American Institute of Physics Inc.. All rights reserved.
