Antibacterial Efficacy of Susu Banana (Musa paradisiaca L.) Peel Methanol Extract and The Total Contents of Flavonoid and Phenolic Compounds

Abstract Banana peels contain antimicrobial properties. The objectives of this study are to determine the antibacterial efficacy methanol extract susu banana and quantify total amount phenolic flavonoid components present. Maceration techniques were used for extraction. agar diffusion method was applied efficacy. UV-Vis Spectrophotometry technique performed amounts flavonoid. S. aureus E. coli severely inhibited by extract. With an increase in concentration, activity increased. Minimum Bactericidal Concentration (MBC) 4 15%, but Inhibitory (MIC) 3 10%, respectively. had a 1883,73 mg QE/100 g extracts flavonoids 273,09 GAE/100 phenolics,
