Oil palm is a plant that has high economic value because it can produce vegetable oil. In the cultivation of oil palm can be attacked by pests or diseases. One of the main pests that attack is Oryctes rhinoceros or commonly known as the horn beetle. This beetle can attack the top of the oil palm so that it can affect the growth of the oil palm and ultimately result in low yields. If the damage has reached 90%, it can cause a decrease in production by up to 70%. The action that is considered effective is to use control by utilizing the entomopathogenic bacteria Bacillus thuringiensis. This bacterium is considered good for eradicating pests because this bacterium contains protein crystals that can destroy the digestion of insect pests. The method used in this study was a completely randomized design using 5 treatments including a control with 4 replications. The solid waste used plays a role in the growth of B. thuringiensis bacteria bran as a carbon source, while palm oil cake, tofu dregs, peanut meal and corn husks are a nitrogen source. This research was conducted for ± 6 weeks and was carried out at static temperature in the Entomology Laboratory, Faculty of Agriculture, Sriwijaya University. It was obtained from the analysis data that the treatment using rice bran as a carbon source and oil palm cake as a nitrogen source had the highest bacterial colony density so that the resulting toxicity could affect the mortality of O. rhinoceros larvae. This is characterized by characteristics such as changes in color on the bodies of the larvae, body textures that become flabby and larvae that emit a foul odor.
