  • Background: One of the infectious diseases that increased morbidity and mortality rate in hospital was nosocomial infection. Pseudomonas aeruginosa was one type of microorganism that often caused nosocomial infections. The banana peel had traditionally used orally or topically as a medicine to treat diarrhea, dysentery, intestinal colitis, pain and snakebite. Purpose : To determine the antibacterial effect of banana peel extract (Musa paradisiaca L.) on the growth of Pseudomonas aeruginosa in vitro. Methods : Experimental post test only with control group design, used tube dilution test with concentration of banana peel extract 100%, 50%, 25%, 12,5%, 6,25%, 3,125%, 1,56%, 0,78% , 0.39%, 0%. Data were analyzed using Saphiro-Wilk, Kruskal-Wallis and Post Hoc Mann-Whitney Discuss and Results: MIC (Minimal Inhibitory Concentration) couldn’t be observed. MBC (Minimal Bactericidal Concentration) at concentration 1.56%. Data analysis with Saphiro-Wilk at 0% concentration had significance of 0.000 (p <0,05) and continued with Kruskall-Wallis because data was’nt normally distributed. Kruskal-Wallis test showed a significant difference between treatment groups with a significance value of 0.001 (<0.05). The Mann-Whitney Post Hoc test showed that all treatments given banana peel extract when compared with positive controls showed significant results (p <0.05). Conclusion: The banana peel extract (Musa paradisiaca L.) has the effect of decreasing the growth of Pseudomonas aeruginosa in vitro.
