Abstract
Fuel alternative diesel, with efforts to develop environmentally friendly alternative fuels in Indonesia. The purpose of this study was to determine the physical properties and quality of diesel produced from coconut shell liquid smoke, B20, and B40. The test of the quality and physical properties of diesel in question is the Calorific Value, Viscosity, Density, and Cetane Number test. From the engine performance testing, the parameters sought are torque, power and specific fuel consumption, for testing the physical properties of diesel from the comparison of the fuel used, among others, the highest torque value was obtained at 32.415 Nm on diesel fuel for the engine shaft rotation of 1980 rpm with the mass load is 9.6 kg. Fuel consumption specific was obtained from diesel fuel with the largest rotation of 3548 rpm using 337.4 g/kWh while the lowest value was obtained from diesel B40 with a torque value of 24,702 Nm with a mass fuel consumption specific (SFC)) lowest was found in coconut shell oil mixture with the largest rotation of 1520 rpm using 40.9 g/kWh. The conclusion is that the addition of coconut shell oil in diesel can reduce energy because the calorific value is decreasing, as evidenced by the addition of coconut shell oil the engine performance is decreasing.
