## Abstract
Abstract We have been synthesis silver nanoparticles by using chemical analysis and successfully reduce silver nanoparticles by femtosecond laser fragmentation method with various silver nanoparticles size ranges from 60 - 75 nm, 10 - 35 nm and 9-17 nm. Characterization is carried out by Modular UV-Vis Spectrometer (MayaPro200, Ocean Optics) and Transmission Electron Microscope (TEM FEI Tecnai G20 S-Twin 200kV). Based on the results, silver nanoparticles (particles size are 9-17 nm) is high potential for detection of ammonia residues by ammonia PPM enhancement (10 PPM, 100 PPM, 150 PPM, 200 PPM, 250 PPM, 300 PPM, 350 PPM, 400 PPM, 450 PPM, and 500 PPM) and a maximum shift of absorbance at a wavelength of 433.39 nm, while TEM characterization have the structure is round.
