Abstract

Averrhoa bilimbi contains active compounds in the form of saponins, polyphenols, flavonoids, danglycosides which provide anti-microbial effects that can be used as inhibitors of the growth of Streptococcus pyogenes bacteria. Streptococcus pyogenes is one bacterium that can cause infectious diseases. In general, Streptococcus pyogenes can cause pharyngitis (sore throat) and impetigo (skin infection).Then, the purpose of this study was to analyze the effect of various concentrations of Averrhoa bilimbi in the formation of inhibitory zones of the growth of Streptococcus pyogenes bacteria. The population in this study was the whole of Streptococcus pyogenes bacteria, and the sample of this study was pure culture of Streptococcus pyogenes bacteria. This research was conducted at the Biomedical Laboratory of the University of Muhammadiyah Malang, on October 1 to 11, 2018. The data analysis techniques used were the Kruskal Wallis Test and the Mann Whitney Test. The results showed that there was an effect of giving various concentrations of Averrhoa bilimbi to the inhibition zones of the growth of Streptococcus pyogenes bacteria. The concentration of Averrhoa bilimbi which has the best effect on the inhibitory zone diameter of Streptococcus pyogenes bacteria which is 25% with an average inhibition zone diameter of 1,392 mm. The deriving results of this study can be developed as a learning resource for biology in the form of posters.
