The problem of increasing scarcity of petroleum. This encourages researchers to develop alter-native fuels. This study attempts to compare and analyze the volumetric efficiency of the mixture of PER-TAMINA Biodiesel and D70J30 fuel mix (70% Biodiesel PERTAMINA and 30% Jatropha Biodiesel). The purpose of this research is to know the ratio of volumetric efficiency of fuel mixture D70J30 with PERTAMINA biodiesel in 4-stroke direct injection diesel motor, 4-cylinder engine with 2.8-liter cylinder volume, in order to find solution to improve engine performance. The method used in this study is experimental. The results showed the volumetric efficiency of diesel engines when using D70J30 mixed fuel at 25%, 50%, 75% and 100% loads was 83.71%; 83.96%; 83.96%; 83.84% decreased compared to volumetric efficiency of PERTAMINA biodiesel at 25%, 50%, 75% and 100% loads were 89, 5%; 89, 7%; 89, 5%; 89, 7%. The implications of the research results are the power and torque of the diesel engines are also down. In order to improve engine performance there are two ways that can be done, first fix the fuel mixture D70J30, the second modify the engine.
