UJI EFEKTIVITAS ANTIBAKTERI EKSTRAK DAUN KERSEN (Muntingia Calabura L) TERHADAP BAKTERI STAPHYLOCOCCUS AUREUS

ABSTRACT Background :Kersen leaf contain secondary metabolite substance such as flavonoid, tannin and saponin, which combining them could use as antibacterial. purpose : The Purpose of this research to recognize effectiveness of Kersen leaf as antibacterial (Muntingia Calabura [L]) towards Staphylococcus Aureus. Research method :This research is a experimental study with posttest only control group design. This research was conducted on May 2015. In this research there are two group namely intervention and control, sample is Staphylococcus aureus culture. This research using five concentration extract of Kersen leaf namely 12,5%, 25%, 50%, 75% dan 100% and two control : positive control (Amoxycilin) besides negative control solvent, each treatment repetitive 5 time for each group. KHM value determine by measure inhibition zone diameter on blood agar media which has streak bacterial suspension from each concentration than incubate for 24 hours. Then data were inhibition zone diameter were analyze used one-way ANOVA with P scor
