Short Communication: Inhibitory effect of Sapindus rarak ethyl acetate extract on Staphylococcus aureus

Abstract

Abstract. Silviani S. 2017. Short Communication: Inhibitory effect of Sapindus rarak ethyl acetate extract on Staphylococcus aureus. Bioteknologi 14:1. The research aimed to know the Minimum Inhibitory Concentration (MIC), the Minimum Killing Concentration (MKC) and the inhibitory fungal zone of Sapindus rarak - ethyl acetate extract on Staphylococcus aureus. The research used an experimental descriptive design by using controlled post-test approach by measuring the value of MIC, MKC and the inhibitory fungal zone. This research was performed in 2016 at the Bacteriology Laboratory of Akademi Analis Kesehatan Nasional (Academy of National Health Analyst) by using dilution method and diffusion disc. The result of this research showed that the value of MIC was not able to be concluded, the value of MKC was 80% and the greatest inhibitory effect zone achieved at 100% concentration was 10.3 mm. The ethyl acetate extract claimed medium to strong inhibitory effect on Staphylococcus aureus.
