One of the medicinal plants commonly used by the public is turmeric. Turmeric has active compounds can inhibit the growth of bacteria. Methods: Type of research True Experimental Laboratories with research design Post Test Only Control Group Design. This research used turmeric extract concentration 100%, 50%, 25%, 12,5%, 6,25%, 3,12%, 1,56%, 0,78%. The extract is created using maseration method, diluting series with dilution method, calculating MIC and MBC. Results: Test Saphiro Wilk and Levene test showed the value of p> 0.05 shows that the normal distribution of data. One Way Anova test results showed that p <0,05 showed that there was a significant difference overall. LSD test results there is a significant difference between the study groups. Conclusion: Turmeric extract (Curcuma domestica) has antibacterial power on growth of Streotococcus mutans bacteria at 3.12% MIC and 6.25% MBC.
