TES INHIBISI PADA DAUN SIRIH MERAH (Piper crocatum) TERHADAP Staphylococcus aureus DAN Salmonella typhi
Abstract: The red
betel leaves (Piper
crocatum) has many
benefits such as
antioksidant, antidiabetic, antineoplastic, antiseptic, and
antiinflammation. This research
aims to investigate
the antibacteial activity
on red betel
leaves againsts
Staphylococcus aureus and
Salmonella typhi with
determine the red
betel leaves extract
minimum resist concentrate which
capable to inhibit
the growth of
bacteria. This research
was held on
October 2014 at Microbiological Laboratory
of Lampung University
Medical Faculty. The
red betel leaves
extract obtained from Organic
Chemical Laboratory of
Lampung University with
maceration technique. The
sirih merah leaves
activity performed with in vitro particularly with Kirby bauer method
which is done by making the well. The results of this research presented that
all concentration of red betel leaves such 3,125%, 6,25%, 12,5%, 25%, 50% and
100%, has antibacterial activity towards
Staphylococcus aureus and
Salmonella typhi bactery,
with the highest
