Nanotechnology is one of science technology that current interest due to their wide variety of application in fields. Nanoparticle has different characteristic from previous macroscopic characteristic before it is turned to Nano-size. This research aims to get the optimum condition to synthesize silver nanoparticle from ethanol extract of Kawista (Limonia acidissima Groff). Extraction was done by refluxs method. Different variation does the optimization of silver nanoparticle, i.e., with and without incubation, with and without stabilizer, with and without stir, and stirrer time variation. The optimum condition to synthesize silver nanoparticle was conducted based on characterization result from UV-Vis Spectrophotometric method, and particle size from particle size analyzer result. The optimum condition to synthesize silver nanoparticles was done using AgNO3: 1% ethanol extract = (10 :1), 5 hours of stirred and 15 hours of incubation time. Those silver nanoparticles are 130, 4 nm in particle size and 0,295 in polydispersity index. Per SEM characterization, silver nanoparticles have a rod and ellipse in shape.
