Result obtained by means parametric statistic test, that is one way-ANOVA, obtained p value 0.001 (p<0.05), so there is a significant difference in the inhibition zone of the three groups. Result of Post Hoc Test, that is Least Significant Difference (LSD) obtained p value 0.001 (p<0.05), there is significant difference in the measurement of inhibition zone between groups. Piper betel leaf extract is 25% more effective than lemongrass extract 25% and amoxicillin 500 mg against the growth of Staphylococcus aureus.
