摘要

Mentawai islands of West Sumatra province have a fairly extensive coastal areas and stored wealth of the sea has high economic potential, one of which is Teripang (Sea cucumbers).

In the field of dentistry, Streptococcus viridans is one of the main bacteria that cause dental health problems in oral cavity. This bacterium is normal flora in oral cavity that can cause dental caries. This study aims to determine antibacterial activity of extract of Sea Cucumber (Stichopus variegatus) of Mentawai Islands against Streptococcus viridans. Results of the study tested using ANOVA with a significance level of 5%. The study revealed an average diameter of inhibitory zone gamat extract of sea Cucumber (Stichopus Variegatus) of Mentawai Islands against Streptococcus viridans. The highest concentration was 2.5% to the value of 8.45 mm in the medium category. P-value of the ANOVA test was <0.05 (p=0.012). Based on the results of the study concluded that there are antibacterial activity of extracts of Sea Cucumber Stichopus Variegatus of the Mentawai Islands against the bacteria Streptococcus viridans.
