    Abstract
    Parepat/pidada putih (Sonneratia alba) is a type of mangrove plant that is used by the traditional tribe for natural medicine. This study uses leaves and stem bark extracted with ethanol. Antibacterial assay uses Ralstonia Solanaceaerum and Streptococcus sobrinus by diffusion agar method. The concentrations used were 5000ppm, 10000ppm, 20000ppm with positive control (Chloramphenicol), and negative control (Ethanol 40%). The results of this study obtain the moisture factor of S. alba leaves has a humidity of 0.31 and stem bark of 0.49. The yield showed that the amount of S. alba leaf extract was 23.86% and the bark was 7.31%. S. alba leaf extract was able to inhibit the bacteria R. solanacearum at concentrations of 5000ppm, 10000ppm and 20000ppm with inhibitory values of 27.46%, 34.34% and 37.78%, respectively. While bark extract can inhibit R. solanacearum at concentrations of 5000 ppm, 10000 ppm and 20000 ppm with inhibitory values of 35.38%, 38.47% and 41.92%, respectively. S. alba leaf extract is able to inhibit S. sobrinus bacteria only at concentrations of 10000 ppm and 20000 ppm with inhibitory values of 28.07% and 48.51%. Whereas S. alba bark extract was able to inhibit S. sobrinus at a concentration of 5000 ppm, 10000 ppm and 20000 ppm with inhibitory values of 16.18%, 49.02% and 61.27%
