Abstract

Abstract: Nyiri ( Xylocarpus granatum ) thrives in the mangrove areas of Indonesia, especially Tarakan, North Kalimantan. X. granatum is one of many species found in the Tarakan mangrove forest and belongs to the Meliaceae family. This plant has been utilized by communities for pesticides and health care. So, the purpose of this study is to determine the potential of X. granatum in inhibiting the growth of Ralstonia solanacaerum and Propionibacterium acnes. This study we used well agar diffusion methodology with a concentration of 5000 ppm, 10, 000 ppm, 20, 000 ppm. Positive controls in this study were Chloramphenicol and 40% ethanol as negative control. The determine variables are the percentage of inhibition diameters (DDH). The percentage of DDH shows that the ethanol extract of leaves and bark X. granatum against R. solanacearum and P. acne at a concentration of 5000 ppm was not able to inhibit, whereas the concentration of 10, 000 ppm and 20, 000 ppm was able to inhibit the R. solanacearum with a percentage of 31.09 respectively % and 34.46%. Whereas, the bark extract was able to inhibit R. solanacearum with the percentage of DDH at a concentration of 10, 000 ppm was 35.73% and 20, 000 ppm was 39.94%. Furthermore, ethanol extract of X. granatum leaves against P. acne was able to inhibit the concentration of 10, 000 ppm with a value of 33.83% and 20, 000 ppm with a value of 38.01%. The percentage of DDH for X. granatum bark is able to inhibit P. acne at all concentrations, namely at concentrations of 5000 ppm (35.34%), 10, 000 ppm (39.59%) and 20, 000 ppm (41.63%).
