Method: True experimental laboratory with a post-test only control group design and 24 samples. Cherries were extracted by using maceration. Then, the phytochemical test was conducted to discover antibacterial substances. The antibacterial test was done by using the dilution method to know Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC). Results: Minimum Inhibitory Concentration (MIC) could not be seen, and Minimum Bactericidal Concentration (MBC) showed that all concentration 6,25%, 12,5%, 25%, and 50% and positive control were able to kill a bacterium L. acidophilus. Conclusions: There is an influence of cherry extract on the grow
