Biosintesis Nanopartikel Perak Menggunakan Ekstrak Kulit Buah Nanas Untuk Deteksi Hidrogen Peroksida Berdasarkan Metode Kolorimetri

---

The biosynthesis of silver (Ag) nanoparticles has been carried out by reacting pineapple
peel extract and AgNO3 solution. Ratio of the composition of the extract and the
AgNO3 solution, namely, 1: 1 by varying the AgNO3 concentration of 1 mM, 2.5 mM,
and 5 mM. The nanoparticle synthesis process was carried out at 80oC for 30 minutes.
The nanoparticles obtained were characterized using UV-Vis, FTIR, and XRD to study
their physical properties, functional groups, and crystalline properties. Furthermore,
the Ag nanoparticle sample was tested for sensitivity to Hydrogen Peroxide (H2O2).
Characterization with the UV-Vis spectrophotometer showed the formation of
nanoparticles which is indicated by the absorbance peaks of each sample of 1 mM, 2.5
mM, and 5 mM at a wavelength of 403 nm, 405 nm, and 406 nm. XRD pattern shows
that the diffraction peaks have a Miller index of each diffraction peaks (111), (200),
(220), and (311). FTIR characterization of each sample showed the optical uptake of
the functional groups O-H, C=O, and C≡C, which are the polyphenol content of
pineapple peel extract. H2O2 sensitivity examined using AgAC 2.5 mM, there is still a
solution of Ag nanoparticles. The optimum sensitivity test found in the 1 mM AgNO3
sample which was characterized by a significant change in the color of the solution in
a short time.
Keywords: Biosynthesis, Pineapple peel, Silver nanoparticles, H2O2
