Replacing alcohol with herbs could avoid this side effect. Cloves have been proved to have antibacterial properties. However, most researches used complex extraction methods that might not be applicable on a household scale. Objective: To prove that clove extracts have ability to inhibit and to kill S. aureus and E. coli . Methods: This is an experimental study by using post-test only control group design. Clove extract was obtained with simple aqueous maceration. Samples were Staphylococcus aureus ATCC 25923 and Escherichia coli ATCC 25922 allocated into six groups: clove extracts at concentrations of 12.5%, 25%, 50%, 100% respectively; 70% alcohol as a positive control; and aquadest as a negative control. Each group was given 5 repetitions of intervention. MIC was measured with dilution method, while MBC with streak method. Negative controls were only used to monitor the quality of this work. Results: MIC of S. aureus was started at 50% concentration of clove extract, while MBC of S. aureus was started at 25 % concentration of the same extract. MIC and MBC of E. coli was both started at 25% concentration of clove extract. MIC and MBC of 100% concentration of clove extract were equal with 70% alcohol. Conclusion: Concentration of 100% clove extracts have similar ability with 70% alcohol to inhibit and to kill S. aureus and E. coli.
