Banana (Musa paradisiaca L.) as famous tropical fruit around the world. The one important and destructive disease of banana is Fusarium wilt caused Fusarium oxysporum f.sp. cubense (Foc). Foc as soil-borne pathogens and movement of pathogen through the rhizome and water, capable survive in waste crops at the field. The purpose research is to study physiological character of Bacillus sp. such as : ability of bacteria produced IAA (Indole Acetic Acid), gibberelin (GA3), ability phosphate solubilizing and produce salicylic acid as biological control against Foc. The research was conducted from March to November 2018 located in The Agricultural Biotechnology Laboratory, Center of Research Hasanuddin University, Makassar Indonesia. The result was showed Bacillus sp. at PAA 2 produced the highest concentration of IAA in the range approximately 3.26 mgl-1, followed by PAA 3 (2.67 mgl-1). However, PUA and PKT 3 isolates produced the lowest IAA with a value of 1.093 mgl-1 and 1.037 mgl-1. Based on the analysis results was showed that the highest concentration of GA3 at PAA 3 (4.17 mgl-1), followed by PBT (4.16 mgl-1) and PMT 1 (4.15 mgl-1) while the lowest concentration of GA3 was produced by PUA (4.03 mgl-1). Based on the results showed that PBT isolates containing Bacillus sp. from the soil giving highest number in phosphate solubilizing (10.89 mgl-1), followed by PUA 2 (8.96 mgl-1) and PMT (8.47 mgl-1). The lowest result in phosphate solubilizing showed at PAA 3 (4.19 mgl-1). Based on the result, the concentration of Bacillus sp. the highest was found in PAA 3 (9.42 mgl-1), followed by PMT (7.79 mgl-1) and PKT1 (6.13 mgl-1). The lowest salicylic acid concentration was shown by PKA 3 (3.39 mgl-1). The presence Bacillus sp. as endophytic microbe living at rhizosphere and roots of banana giving important information for management Foc.
