This research is geared by the depletion of the availability of fossil fuels in nature. This is inversely proportional to the level of fossil fuel consumption, which is getting higher from year to year. Thus, there is a need for alternative fuels. One of which is biodiesel. The existence of an assessment in preparing biodiesel as an alternative fuel is significant. This study aims to determine the effect of the addition of bioaditive essential oil (eucalyptus) on the performance of diesel engines. The method used in this research was the manufacture of biodiesel through esterification and transesterification steps, then testing the diesel engine to determine the performance and gas emissions were also carried out. The results show that brake torque has decreased along with the loading at each engine speed. The value of brake power increases from 1700 rpm to 1900 rpm and then decreases to 2300 rpm. Brake fuel consumption increases with increasing engine speed, and thermal brake efficiency decrease with increasing engine speed. The CO emission is constant, but in the B20 biodiesel sample with 0.1% eucalyptus oil additive, the CO emission increases to 2100 rpm. CO 2 and HC emissions fluctuate with an increasing trend with increasing engine speed. O 2 emissions fluctuate with a decreasing trend along with the increase in engine speed, the O 2 content produced by pure biodiesel B20 is lower than B20 with additives
