dc.description.abstractThe aim of this study was to determine the ability of Alpinia galanga rhizome aquoeous extract as reducing agent of silver metal to nano-sized silver metal. Microwave was used in order reaction time. Various ratio of Alpinia galanga rhizome rhizome aquoeous extract and 10-3 M silver nitrate solution (v/v) were 1:1; 1:5; 1:10 and 1:20 for the reaction time of 30; 60; 90; 120; 150 and 180 s. Color changing was to started at 60 s reaction and the color was darker by the increasing of incubation time. These biosynthesized silver nanoparticles were characterized by using UV-Vis spectrophotometer. UV-Vis spectra showed that the compounds were silver nanoparticles because they produced peaks at 405-500 wavelength. Among those various of ratio, it ws found that the ratio of 1:10 produced the best spectra at 120 s reaction time. Antimicrobial activity of silver nanoparticles was better than Zingiber officinale and Alpinia galanga rhizome aquoeous extracten_US
