ABSTRACT This research aims to synthesize silver nanoparticles (Ag-NPs) using red betel leaf extract (Piper crocatum), which is used as a catalyst to degrade methylene blue. The extract of red betel leaf contains flavonoids and tannins, was used as bioreductors of Ag+ to Ag0 and stabilize silver nanoparticles. The volume ratio of red betel leaf extract to solution of AgNO3 0,1 M was varied by …
