One of the plants is Persea americana Mill. In this research, part of the Persea americana Mill used was leaf. The purpose of this research were to determine the effect antibacterial compounds ethanol extract and to know the minimal inhibitory concentration of ethanol extract of Persea americana Mill. leaves on the growth of Staphylococcus epidermidis. This research was an experimental research laboratory and the methods used in this research was difussion method. The concentation used in this research were 0,05%, 0,1%, 0,2%, 0,3%, 0,4%, 2%, 4%, 6%, 8%, and 10%. The result of this research were analysed by using SPSS One Way ANOVA test and the results showed that the ethanol extract of Persea americana Mill had significant effect in inhibiting the growth of Staphylococcus epidermidis with significance 0.000. The minimal inhibitory concentration of ethanol extract of Persea americana Mill leaves on the growth of Staphylococcus epidermidis was 0,2% with the diameter zone of 0,50 mm.
