Pengaruh Pemberian Ekstrak Etanol Biji Mahoni (Swietenia mahagoni) terhadap Penghambatan Pertumbuhan Escherichia coli dengan Metode Difusi Cakram
Abstract: Escherichia coli is
commonly known as nonpathogenic bacteria, but some strains are pathogenic and
cause diarrhea, urinary tract infections, and meningitis. Escherichia coli is
initially sensitive to antibiotics, but lately began resistant. Alternative antibacterial
can be obtained from extracts of certain plants, such as mahogany (Swietenia
mahogany). This research aimed to determine the effect of various
concentrations of ethanolic extract of mahogany seeds to growth inhibition of Escherichia coli FNCC 0091 and determine the
concentration that could optimally inhibited the growth of Escherichia coli
FNCC 0091. Mahogany seeds extract was prepared by maceration method with 96%
ethanol. Antibacterial activity was done by disc diffusion method. Data
obtained were diameter of clear zone. Data were analyzed using one-way analysis
of variance followed by Duncan's test. Results showed that the ethanolic
extract mahogany seeds could inhibited the growth of Escherichia coli FNCC
0091. The best treatment was ethanolic extract of mahagony seeds at
concentration 100% and 80% with clear zone of 2.33 mm and 2.13 mm.
