Abstract

Dadap serep stems contain secondary metabolite compounds of flavonoids, saponins, isoflavonoids, alkaloids and lectinswhich can act as reducing agents in the biosynthesis of nanosilver.This research aims to determine the effect of the concentration of liquid extract of dadap serep stem on the green synthesis silver nanoparticle (AgNPs)process.The aqueous extract of dadap serep stemreactedwith onemM AgNO3in a ratio of volume 1: 1 (FI), 1: 2 (FII), and 2: 1 (FIII). Characterization of AgNPs includes Surface Plasmon resonance (SPR) using UV/Vis spectrophotometer at wavelengths of 300-700 nm, particle size,and zeta potential using a particle size analyzer (PSA).The result showed that the SPR of AgNPvalues is 429-436 nm.AgNPs FI, II, and III particle sizeswere 66.13 nm, 75.76 nm, and 75.96 nm, respectively. The PDI values below 0.5 confirmed that the distribution of nanoparticles was uniform.Themost stable nanoparticleis Formula I.
