Sintesis Nanopartikel Perak Dengan Menggunakan Bioreduktor Ekstrak Kulit Kecapi (Sandoricum Koetjape)

ABSTRACT
Silver nanoparticles (Ag) are materials that have extensive applications with
diverse synthesis methods. The process of biosynthesis using plant extracts shows
satisfactory results with a unique shape. Silver nanoparticles have been
successfully synthesized by biosynthesis method using kecapi extract
(Sandoricum Koetjape). This study aims to analyze the effect of AgNO3 precursor
concentration comparison and harp skin extract on it’s physic and chemical
properties by varying its volume comparison by 1:4, 2:3, 1:1, 3:2, and 4:1.
Synthesis of silver nanoparticles is performed at a uniform temperature and pH of
80oC, and 10. Optic fibers, particle sizes and function groups are analyzed based
on the characterization of UV-Vis Spectroscopy (Ultraviolet-Visible), TEM
(Transmission Electron Microscopy) and (Fourier Transform Infra Red). UV-Vis
spectroscopy shows the peak absorption characteristic of Ag nanoparticles at
wavelengths ~ 390-412 nm. The highest absorption occurred in the 3:2 sample at
0.329 a.u. The results of the FTIR (Fourier Transform Infra Red) analysis show
that the carbonyl group (C=O) acts as a reduction and caping agent. The results of
TEM (Transmission Electron Microscopy) analysis showed the average diameter
size of the sample 1:1, 3:2, 4:1 which is 14.4 nm, 10.8 nm, 8.6 nm and standard
deviation ±7.07 ; ±4.17; ±3.95. The results prove that kecapi extract can reduce
Ag2+ ions to Ag0. The size and absorption of optic nanoparticles is also influenced
by the composition of the excretion with its precursors where the average size of
the smallest silver nanoparticles with the most uniform particle size distribution is
found in the 4:1 sample.
Keywords: Silver Nanoparticles, Sandoricum Koetjape, Biosynthesis.
