The main disease in chili is fusarium wilt caused by Fusarium oxysporum f. sp. capsici that can cause losses up to 100%. The aim of this study was to obtain a solid formula for the endophytic bacterium Bacillus cereus strain SLBE3.1AP with a carrier that can be stored longer and is effective for controlling Fusarium oxysporum f. sp. capsici. This research was an experimental study to see the ability of the solid formula of Bacillus cereus bacteria strain SLBE3.1AP in controlling Fusarium oxysporum f. sp. capsici using Completely Randomized Design consisting of 15 treatments and 3 replications. The treatments consisted of carrier material for the formula bagasse, rice straw, bran, fungicide and control. Each solid formula of Bacillus cereus strain SLBE3.1.AP was introduced to chili seeds and seedlings. The results showed that the best formula for controlling Fusarium oxysporum f.sp. capsici and increasing the growth of chili plants was a solid formula of B. cereus strain SLBE3.1AP with 6 weeks storage of bagasse, 4 weeks of storage of rice straw, and 6 weeks of storage of rice bran.
