SUMMARY The aim of this study was to determine the ability of Zingiber officinale and Alpinia galanga rhizome aquoeous extract as reducing agent of silver metal to nano-sized silver metal. Microwave was used in order reaction time. Silver nanoparticles was synthesized by mixing the water extract with 10-3 M silver nitrate solution. Various ratio of Zingiber officinale rhizome aquoeous extract …
