ABSTRACT
In Vitro Antibacterial Ability of Metanolic Extract of Red Ginger
(Alpini purpurata K. Schum) Root Against Staphylococcus aureus And
Escherichia coli.

The red ginger was used as cooking spices, but it was also used as traditional medicine to treat skin fungus, ringworm, fever, fatigue, diarrhea, toothache, and as aphrodisiac. The purpose of this research was to know the antibacterial ability of metanolic extract of red ginger root in different concentration against the growth of Staphylococcus aureus And Escherichia coli In Vitro. This researh was laboratoric experimental using Completely Randomized Design and Kirby-Bauer disk diffusion method. The sterilized red ginger root extract was devided into 4 different concentrations 100%, 50%, 25%, and 12,5% using aquadest, amoxiclav as positive control and aquadest as negative control. The data was analyzed using analysis of variance then continued with Duncan New Multiple Range Test (DNMRT) p<0,05. The result showed that all of tested concentrations have the ability against S. aureus and E. coli which the largest clear zone was the 100% extract, but smaller than amoxiclav. Observed from the effectiveness, metanolic extract of red ginger root was more effective against S. aureus than E. coli.
