Streptococcus mutans is a known bacterium that can cause dental caries and is a serious problem in the oral cavity. The purpose of this study was to determine the inhibition of Bandotan leaf extract and siwak stem powder extract on the growth of the S mutans bacteria. This research used the descriptive method, with the design of this study was experimental. The research subject used was the bacteria S mutans, the design in this study was by making a solution of Bandotan ( Ageratum Conyzoides ) leaf extract and siwak stem powder with a concentration of 100%, 75%, 50%, 25% and 10% and 4 times repetition, then made suspense bacteria S mutans i.e. bacteria grown on PCA media were given a paper disk that had previously been dipped in a Bandotan ( Ageratum Conyzoides ) leaf extract solution and siwak stem powder, then incubated for 1x24 hours in the incubator, the results were observed and measured (posttest) in the oligodynamic region of the inhibitory area diameter growth of bacterial mutans by using calipers (mm). The data obtained were analyzed using quantitative descriptive analysis methods and then performed iji annova. The results showed that both extracts were able to inhibit the growth of the bacteria S mutans, although it has a very weak inhibitory power that is an average of 4x experiments is 9.32 mm and it is hoped that this research can be developed again with other methods so that the results obtained are optimal.
