Green Synthesis Silver Nanoparticles (AgNPs) Utilizing Ari (Pithecellobium jiringa) Skin Waster Extract as a Bioreductor

Abstract

In this study, silver nanoparticles (AgNPs) are widely applied as antibacterials and can be composited with polymers for automotive components. Pithecellobium jiringa epidermis waste extract contains several secondary metabolite compounds that can act as bioreductors to produce AgNPs. This research aims to synthesize silver nanoparticles (AgNPs) using P. jiringa epidermis waste extract as a bioreductant. The volume ratio of P. jiringa epidermis extract and 1 mM silver nitrate (AgNO₃) solution is 3:7 at 25℃. Characterization of AgNPs using U-Visible (UV-Vis) Spectrophotometer, Particle Size Analyzer (PSA), Scanning Electron Microscopy (SEM), Energy Dispersive X-ray Spectroscopy (EDX), Fourier Transform Infrared Spectroscopy (FTIR), and X-Ray Diffraction (XRD) The results of UV-Vis, PSA, and SEM-EDX analyses, respectively, obtained AgNPs with an adsorbance of 2.121 at a wavelength of 430 nm at a reaction time of 96 hours, an average size distribution of 46.6 nm with a round shape, the element content of AgNPs, namely Ag, C, and O. wave number 2867.74 cm^-1, and the C=C functional group at wave number 1613.18 cm^-1.
