Abstract

Klebsiella pneumoniae is a bacterium that is capable of causing infections in the urinary tract, lungs, respiratory tract, injuries, septiksemin, digestive tract and liver. Inappropriate use of antibiotics in inappropriate dosages can cause resistance to antibiotics. The purpose of this study was to determine the ability of ethanol extract of matoa leaf (Pometia pinnata) in inhibiting the growth of Klebsiella pneumoniae bacteria and the concentration that produced the biggest inhibition zone in the growth of Klebsiella pneumoniae. The method used is Kirby-Bauer with variations in the concentration of 100%, 75%, 50% and 25%. The results of the data obtained were analyzed using Microsoft Excel to obtain a bar chart of the growth of Klebsiella pneumoniae. The results of inhibition zones formed from each extract at a concentration of 100%, 75%, 50% and 25% respectively were 16.4; 15.6; 9.63; and 6.35mm. The ethanol extract of matoa leaf is able to inhibit the growth of Klebsiella pneumoniae and the concentration of 100% is the concentration that forms the largest inhibitory zone to the growth of the Klebsiella pneumoniae by producing an inhibition zone of 16.4 mm.
