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 1:1, 1:5, and 1:10. Optical properties of green synthesis AgNO3 was characterized by a UV-vis spectrophotometer, which shows absorption peaks at 418, 412, and 416 nm. The optimum volume ratio was obtained at a ratio of 1:10. XRD analysis shows that the nanoparticles produced were silver nanoparticles with a Face Centered Cubic (FCC) crystalline structure which is characterized by the presence of diffraction peaks at angle 2θ of 27,82° (111), 32,21° (200), 46,25° (220), 54,83° (311), 57,44° (222) dan 77,39° (420). SEM analysis showed that the morphology of silver nanoparticles is non-homogeneous. In addition, the presence of Ag was confirmed by the EDX spectrum of the sample that observed 66,5%. This study showed that higher contact time of degradation will increase the percentage of methylene blue degradation. The degradation activity of methylene blue at a concentration of 25 ppm in an optimal time of 8 hours resulted in degradation values of 66,51%.
Key words : Bioreductor, Silver Nanoparticles, Red Betel Leaf, Methylene Blue, UV-Vis, XRD, SEM.
