Abstract
This research aims to synthesize silver nanoparticles (NPAg) using red betel leaf extract (Piper
crocatum). The extract of red betel leaf contains flavonoids and tannins, which function as
bioreductors of Ag+ to Ag0 and stabilize silver nanoparticles. The volume ratio of red betel
leaf extract to a solution of AgNO3 0,1 M was varied by 1:1, 1:5, and 1:10. The reduction was
monitored from the emergence of absorbance at 418 nm, 412 nm, and 416 nm using a UV-Vis
spectrophotometer. The optimum volume ratio was obtained at a ratio of 1:10 with an
absorbance intensity of 2.139 a.u.
