ANTIMICROBIAL POTENTIAL OF KEPOK BANANA SHEATHS EXTRACT (Musa paradisiaca formatypica) ON THE GROWTH OF Staphylococcus aureus BACTERIA

Abstract

Banana plant is one of the most famous and beneficial plants in the world. Almost all parts of this plant, namely
fruit, leaves, flower buds, stems, pseudo stems (sheaths and flower stem) can be utilized. This study aims to identify
antimicrobial active substances and the antimicrobial potential of Kepok Banana (Musa paradisiaca formatypica)
sheaths. The study was an experimental laboratory to design a post-test only control group. The maceration method
is used to extract the active substance and identify the levels of the antimicrobial active substance using the TLC
Spectrophotodensitometer and the diffusion method (disc) to test the antimicrobial potential. The research data were
analyzed using the Kruskal Wallis test. The positive qualitative test contains flavonoids, phenol, saponins and
alkaloids. The quantitative content of Kepok Banana sheaths extract contains phenol (1,9 mg/ml) dan flavonoid
(93,3 mg/ml) dan tannin (2,7 mg/ml). The results showed differences in antimicrobial potential at various
concentrations (55%, 70%, 85% and 100%) of Kepok Banana sheaths extract with positive and negative controls
(sig = 0.000). There are no effective concentration in inhibiting the growth of Staphylococcus aureus bacteria with
an average inhibition range of 4.47 mm (resistant category) based on the NCCLS standard.
