The increase in Government policy from B20 to B30 towards Jatropha biodiesel tends to increase every year but the current condition is constrained by low yields both in quality and quantity, so that improvement efforts are needed to increase the yield of Jatropha biodiesel. The dosing of Arbuscular Mycorrhizal Fungi (AMF) with Jatropha cultivar and cytokinin concentrations is expected to increase the yield of Jatropha biodiesel in two different locations based on altitude, where the research was verificatived. The experiment starts from January to August 2019 at an altitude of 0-50 masl (lowland) and an altitude of 750-850 masl (medium land). The combination trial evaluated the Jatropha cultivar and the best AMF dosage and cytokinin concentrations that were repeated 3 times. The results of the experiment showed that there was an effect of the best interaction between AMF, cultivars, and cytokinin concentrations on the increased yield of fruit per plant (55.33 g), number of seeds per plant (124.17 g), fruit fresh weight per plant (208.55 g), Fresh weight of 100 seeds (70.22 g), seed fresh weight per plant (39.28 g) and biodiesel oil yield that was increased in Cirebon (42.66% - 47.50%) compared to Jatinangor (35.44%-44.10%).
