Background Dental and oral health is a part of body health that cannot be separated from each
other because dental and oral health can affect the overall health of the body. The risk posed
by poor oral and dental hygiene conditions can increase the occurrence of dental plaque.
Staphylococcus aureus bacteria are most often found, so it is said that this bacterium has an
important role in the formation of dental plaque. Utilization of the decoction is used as an
effort to deal with health problems or diseases that attack. One of the efforts to reduce the
amount of dental plaque in the community requires an inhibitor that can inhibit
Staphylococcus aureus bacteria. One of the natural antibacterials that can be used as medicine
is red ginger (Zingiber Officinalle Var Rubrum). Red Ginger (Zingiber Officinalle Var
Rubrum).Objective: Among this group of bacteria, Staphylococcus aureus is the most
common, so it is said that this bacterium has an important role in the formation of dental
plaque. Staphylococcus aureus is a cariogenic bacteria that can ferment carbohydrates and
produce acids. Usually, the use of red ginger is used as an effort to deal with the problem of
dental plaque formation.Method: This research is an experimental laboratory research
conducted from July to August 2022 at the Central Health Laboratory (BBLK). The method
in this study was to observe and measure the diameter of the inhibition zone of
Staphylococcus aureus bacteria using the paper disc diffusion method. From the calculated
data, the Shapiro-Wilk normality test was carried out, because based on the number of
samples less than 50 samples. If the data were normally distributed, bivariate analysis was
performed using the One Way Anova test or the Kruskal-Wallis test if the data were not
normally distributed.Result: based on the results of statistical tests using the One-way Anova
test obtained p-value 0.000 so that p-value <0.05, which means that the concentration of
boiled water from red ginger tested affects the growth of Staphylococcus aureus (p-value
<0.05) indicates that red ginger boiled water at concentrations of 40%, 50% and 60%
effectively inhibited Staphylococcus aureus bacteria.Conclusion: Based on the results of the
research that has been done, it can be concluded that there is a test of antibacterial activity of
lemongrass (Cymbogopon Citratus) boiled water at concentrations of 5%, 10% and 15%.
