UJI AKTIVITAS ANTIBAKTERI EKSTRAK CANGKANG KELAPA SAWIT (Elaeis guineensis Jacq.,)
Abstract: The active
components of palm oil shell were succesfully extracted by methanol. The
methanol extract was, then, subjected to investigate its antibacterial
properties. The phytochemical screening demonstrated the presence of
triterpenoid and flavonoid compounds. The methanol extract was also tested for
antibacterial activity against Staphylococcus aureus (Gram positive bacteria)
and Escherichia coli (Gram negative bacteria). The triterpenoid and flavonoid
compounds are more sensitive in inhibiting the growth of Gram positive bacteria
(Staphylococcus aureus) than Gram negative bacteria (Escherichia coli). Further,
the concentration of the methanol extract (1%, 5%, 10%, 25%, 50%, 75% and 100%,
respectively), were tested against the Staphylococcus aureus and Escherichia
coli. Inhibition zone was formed starting at a concentration of 5% and above,
while the largest inhibition zone was at a concentration of 100%, as expected.
Minimum Inhibition Concentration (MIC) and Minimum Bactericidal Concentration
(MBC) tests were performed by the method of dilution with concentration of 2%,
4%, 6%, 8%, 10%, 12%, 14%, 16%, 18% and 20%, respectively. The methanol extract
was as effective as bacteriostatic (according to MIC test) against
Staphylococcus aureus and Escherichia coli at concentration 6% and is also
considered effective as bactericidal (according to MBC test) at concentration
14% and 12%, respectively.
