ABSTRACT Indonesia has a remarkable biodiversity that has been widely processed into traditional medicine. One of the plants that efficacious as a medicine is cherry. Cherries are efficacious as antioxidants, type 2 antidiabetes, analgetic, and antibacterial, because it contains flavonoids, saponins, and tannins. Sulaiman in 2017 examined the antibacterial properties of cherry leaves against the colony of Streptococcus viridans, but no one has examined the inhibitory test of cherry leaves for Streptococcus mutans. The purpose of this study was to determine the inhibitory test of cherry leaf extract against Streptococcus mutans. This research is purely experimental. The first stage of the study was extracted from cherry leaves, the second extract of cherry leaves was tested for its inhibitory power against Streptococcus mutans. Extracts were made in 4 groups namely 3 test concentrations namely K1 (15%), K2 (30%), and K3 (60%), and K0 as the control norm. After the cherry leaves extract was made, it was evaluated. Then tested the inhibition against Streptococcus mutans by diffusion method on blood agar media. Data analysis with one-way ANOVA with p value <0.05. The conclusion is the third concentration of cherry leaves extract gives inhibitory power against Streptococcus mutans and the best is K3 of 13.00 mm.
