The aim of this study is to examine the potential antimicrobiaf activity of seed, bark, root and kedawung leaf. It is expected that the result will give information on characteristics and concentration of kedawung part which have the highest antmicrobial activily. The result showed that the bark has the highest antimicrobial activity on Escherichia coli; Vibrio cholerae, Staphylococcus aureus and Bacillus cereus. Extract made from kedewung plant and water (ratio 1:2, b/v) was better than those made with ratios of 1: 1 or 1: 3 (b/v). Heat did not decrease its antimicrobial activity. Extract concentration of 10% (21.40 mg/ml) with contact time of 24 hour decreased bacterial growth but did not inactivate them.
