Abstract:
This study aims to investigate the optical properties of silver nanoparticles (NPP)
using kecapi fruit skin extract (Sandoricum Koetjape). Silver nanoparticles with
kecapi fruit skin extract have been successfully synthesized using biosynthesis
method. Synthesis was done by mixing AgNO3 solution as much as 2.5 mM and
harp skin extract that has a volume ratio of 1:4, 2:3, 1:1. The optical properties of
the sample were analyzed using UV-Vis spectroscopy. UV-Vis spectroscopy
analyzes the absorption of samples. This study resulted in the highest absorption
occurring in the wavelength range of 350-450 nm. The highest absorbance is in a
2:3 comparison sample with a wavelength of 376 nm.
