Abstract

petroleum fuel is predicted to run out if used continuously. One of the renewable energy sources that is an alternative fuel is biodiesel. More than 30 kinds of plants in Indonesia can produce vegetable oil. One of the potential sources is rubber seed oil as a diesel fuel blend. The researcher had the idea to conduct a performance test on the use of biodiesel for a Jeep Willys brand motorized vehicle with Mitshubishi 4DR5 engine using biodiesel based on rubber seed oil. The composition of the mixture used is B30, B40, and B50.

The type of research used includes experimental method research. In this research, experimental testing of diesel fuel + biodiesel blends from rubber seed oil will be carried out and continued with dynotest and road show tests on diesel vehicles. The test variables used in this research are B30, B40, and B50 fuel blends. Then the performance test carried out to determine the performance of the results of this biodiesel fuel mixture is using the dynotest test and roadshow test or can be called a road test.

The lowest power value was obtained in the pure diesel test variable of 36.5 HP. Then the highest power value was obtained in the B40 and B50 test variables of 37.5 HP. B30 has a lower power of about 0.8% compared to B40 and B50. The lowest torque value was obtained in the B50 fuel testing variable. Then the highest torque value was obtained in the B40 fuel testing variable. B30 has a lower torque value of 2.3% compared to B40. In the -1st dynamic test during the day, diesel fuel spent 1 liter of fuel can travel 8.8 Km, B40 fuel spent 1 liter of fuel can travel 9.5 Km. In the 2nd test during the day, diesel fuel spent 1 liter can travel along 8.7 Km, B40 fuel spent 1 liter of fuel can travel along 9.3 Km. In the -1st night test, diesel fuel consumes 1 liter of fuel can travel a distance of 8.5 Km, while B40 fuel consumes 1 liter of fuel can travel a distance of 8.7 Km. In the 2nd test at night, diesel fuel spent 1 liter of fuel can travel a distance of 8.6 Km, while the B40 fuel spent 1 liter of fuel can travel a distance of 9.0 Km.
