AKTIVITAS ANTIBAKTERI EKSTRAK MAKROALGA Padina australis DAN Laurencia nidifica DI KEPULAUAN SERIBU TERHADAP BAKTERI Staphylococcus aureus DAN Escherichia coli
Abstract: Macro algae are
plants that live in the sea, belongs to the group Thalophyta. These herbs
contain bioactive compounds that have the potential in the health field that is
antibacterial. Antibacterial substances used as drugs in the treatment of
several diseases caused by bacteria. Type of macroalgae used in this study is
Padina australis and Laurencia nidifica of Pulau Penjaliran TimurKepulauan
Seribu, using bacteria Staphylococcus aureus and Escherichia coli as test
bacteria. Antibacterial testing method used is the method of dilution with
extract concentrations of 10%; 20%; 30%. For comparison is used as positive
control in the form of chloramphenicol while the negative control used mueler
hinton broth medium. The design used in this study is completely randomized design
factorial. The results show extracts of P. australis and L. nidifica has
potential as an antibacterial with different abilities to the test bacteria. L.
nidifica extract has antibacterial power capability is higher than P.
australis. Both types of macro-algae extract at a concentration of 10% is able
to inhibit the growth of test bacteria E. coli and S. aureus. Test bacteria E.
coli has a more sensitive response to both macro-algae extract when compared
with S. aureus bacteria.
