2021 Prosiding ICTROPS diana Synthesis of Silver Nanoparticle Using Bioreductor Method from Cempedak (Artocarpus integrifolius l. f) Bark Extract
Abstract
Synthesis of silver nanoparticle using bioreductor method from cempedak (Artocarpus integrifolius L. f) bark
extract has been conducted. Steps in this research performed with synthesis of silver nanoparticle using AgNO3
solution with variation of concentration reacted with bioreductor in form of Cempedak (Artocarpus integrifolius
L. f) bark extract, then characterized with Spectrophotometer UV-Vis, TEM (Transmission Electron Microscope)
and PSA (Particle Size Analyzer). Results of maximum wave length measurements with Spectrophotometer UVVis shows the most stable silver nanoparticle is with AgNO3 0,004 M concentration. TEM analysis results shows
silver nanoparticle morphology as rounded and varies in size and shows average particle size in nanoparticle
using bioreductor is 78,66 nm. PSA result analysis obtained particle size distribution in nanoparticle using
bioreductor from 50-170 nm shows that nanoparticles has formed
