Abstract
The synthesis of silver nanoparticles using matoa leaf extract as a bioreductant has been
successfully carried out. In this study, AgNO3 samples were synthesized by varying
the heating time at 0, 30, 60, 90, and 120 seconds using microwave irradiation. The
optical properties of AgNO3 samples were characterized using Ultraviolet-visible
(UV-Vis) spectroscopy. The peak of UV-Vis absorption that occurs is at a wavelength
of 400-460 nm. This result shows that the peak characteristic of silver nanoparticles
with 90 seconds is the most optimum because it produces the highest absorption peak
