Abstract

The secondary metabolite content of Keampferia galanga i.e essential oil, sesquiterpenoid,flavonoid, fenolic compound, and alkaloid were used as an antibacterial agent. The aimed of this researchwere to isolated Keampferia galanga’s anti bacterial compound using various extraction methods i.e stew,infuse, and maseration using ethanol as solvent. The research was laboratory experimental and designed usingcompletely randomized method with 75 μl volume extract and 3X repetition. The antibacterial activity testwere used wall diffusion methods. The inhibition zone were tabulated and analyzed using one way analysis ofvariance (ANAVA). The result showed that there were signifant differences on S. typhimurium growthbetween stew, infuse, and maseration methods on 5 % significant level, but the the inhibition zone were weak(less than 15 mm in diameter). So it can be concluded that the maseration method using ethanol as a solventshowed weak inhibition activity on S. typhimurium growth.
