ABSTRACTWhite galangal rhizome (Alpinia galanga (L.) Willd's) scientifically proven has properties as antibacterial, antifungal, anticancer, antitumor, antioxidant and cytotoxic. In nano size, the contact surface area of the particle becomes larger which can increase the amount of active substance which is isolated more so that the antibacterial activity is stronger. This study aims to determine whether the white galangal extract nanoparticles have antibacterial activity against the bacteria Klebsiella pneumoniae and measure the inhibitory ability of white galangal extract nanoparticles against bacterial growth and compared with white galangal ethanol extract. White galangal was extracted using maceration method with ethanol solvent and nanoparticle formulation made of white galangal extract by ionic gelation method. The antibacterial activity test was carried out using agar diffusion method and observations were made 1x24 hours incubation period, with inhibition zones measured using a millimeter ruler. The results showed that the white galangal extract nanoparticles had antibacterial activity to inhibit the bacteria Klebsiella pneumoniae, with the results of inhibition zone measurements of 22.5 mm. Keywords : Antibacterial, Extraction, Klebsiella pneumoniae, Nanoparticles, White galangal. ABSTRAKRimpang lengkuas putih (Alpinia galanga (L.)

Skin infections most often found in developing countries, especially in the tropics, are purulent skin inflammation (pyoderma), the main cause of Staphylococcus aureus. The increasing number of cases of bacteria that are resistant to antibacterial can encourage the extraction of sources of antibacterial drugs from natural ingredients. One of the plants that is thought to have the antibacterial activity of Staphylococcus aureus is the Neem plant. In this study an antibacterial activity test was carried out with the well diffusion method from 96% ethanol extract of Mimba leaves extracted by percolation method. Previously 96% ethanol extract from Mimba leaves had been identified by secondary metabolites by phytochemical screening and standardized extract testing. Standarization using non-specific parameters (moisture content, ash content and drying losses) found that 96% ethanol extract of Mimba leaves entered a range of standard parameters and in phytochemical screening tests obtained 96% ethanol extract of Mimba leaves containing alcaloid, saponins, tannins, steroids / terpenoids and flavonoids. The results of the study on the antibacterial activity test showed a concentration of 75% ethanol extract of 96% Mimba leaves classified as having strong activity, at a concentration of 50% and 25% classified as having moderate activity. Based on this study it can be concluded that the three concentrations of 96% ethanol extract of Mimba leaves were able to inhibit the growth of Staphylococcus aureus bacteria.
