The entomopathogenic fungi B. bassiana local is an effective biological agent to control pests among of them Oryctes rhinoceros. O. rhinoceros is a pest of palm oil plantation in Indonesia which causing any problem therefore need to control. Increases the mortality level of entomopathogenic fungi B. bassiana local can be done by forming a better formulation, for example flour formulation with the addition of bran flour as a carrier. Bran flour can encourage the entomopathogenic fungi B. bassiana to germinate faster and produce a higher number of conidia so that it can control O. rhinoceros larvae more quickly. This research was conducted using a completely randomized design (CRD) consisting of 5 treatments and 4 replications obtained 20 experimental units each infested ten O. rhinoceros larvae in star 3. The treatment is additional bran flour into 30 g B. bassiana starter made into flour formulation. Additional some of level bran flour to one kilogram empty fruit bunch (EFB) were 0 g. kg - 1 EFB, 0.45 g. kg - 1 EFB, 0.6 g. kg - 1 EFB, 0.75 g. kg - 1 EFB, and 0.9 g. kg - 1 EFB. The result showed of this research B. bassiana flour formulation and additional bran flour 0.90 g. kg - 1 EFB causing total mortality of O. rhinoceros larvae increasing starter from is 77, 50% becomes flour formulation 82, 5%.
