AKTIVITAS ANTIBAKTERI EKSTRAK METANOL BUAH KETAPANG (TERMINALIA CATAPPA LINN.) TERHADAP PERTUMBUHAN STAPHYLOCOCCUS EPIDERMIDIS DAN SALMONELLA TYPHI
ABSTRACT: The most commonly
found disease causing microorganisms are the Staphylococcus epidermidis and
Salmonella tyhpi bacteria. These bacteria can be controlled by using natural
antibacterial ingredients, one of which is the fruit of ketapang (T. catappa).
This research aimed to find out the antibacterial intensity of methanol extract
of the T. catappa fruit in inhibiting the growth of S. epidermidis and S.
typhi. This research used the disc diffusion method. The extract was given
treatments with 25%, 50% and 75%, both positive and negative control
treatments. Each treatment was inoculated with a bacterial suspension, and then
the filter paper that had been soaked in the extract was aseptically placed on
the surface of the media, incubated with a temperature of 370C for 24 and 48
hours, then the area of clear zone around the filter paper was observed and
meassured. The research findings showed that the fruit of T. catappa had an
inhibitory effect against both bacteria tested. The extract of the fruit of T.
catappa at the concentration of 50% was found to be the optimum concentration
for inhibiting S. epidermidis and S. typhi.
