Abstract

Water apple (Syzygium aqueum Alst.) from the Myrtaceae family is native to Malaysia and Indonesia. Chemical content of water cashew leaf is flavonoid, tannin and phenolic. The aim of this research is to know the antibacterial activity of ethanol extract, fraction of n-hexane, ethyl acetate and water from water leaf (Syzygium aqueum Alst.) and to determine the minimum concentration of concentration (KHM) and Minimum Slew Concentration (KBM) from active fraction to bacterium Staphylococcus aureus ATCC 25923. Water apple leaves using maseration method using 70% ethanol solvent, continue fractionation with n-hexane, ethyl acetate, and water solvent. Test antibacterial activity of ethanol extract, n-hexane fraction, ethyl acetate fraction and air fraction on Staphylococcus aureus ATCC 25923 using diffusion and dilution methods. The fraction concentration used for the diffusion method is 50%; 25%; 12.5. The fraction concentration used for the diffusion method is 50%; 25%; 12.5%; 6.25%; 3.12%; 1.56%; 0.78%; 0.39%; 0.19%; 0.09%. The results of ethanolic extract of water apple leaves extract showed fraction of n-hexane fraction of ethyl acetate and water fraction have antibacterial activity against Staphylococcus aureus ATCC 25923. Ethyl acetate fraction has the most active antibacterial activity against Staphylococcus aureus ATCC 25923 with minimum killing concentration of 6.25%.
