ABSTRACT
Silver nanoparticles are produced by chemical method, but this method can have a negative
impact on the environment due to the use of toxic substances. So, green synthesis is more desirable
for producing silver nanoparticles that has the minimum envioronmental hazard. Biosynthesis of
silver nanoparticles was mixed using ketapang leaf extract (Terminalia Catappa) as a bioreductor to
potential of methylene blue degradation. Silver nanoparticles is a good semiconduktor materials used
as photocatalists to methylene blue degradation. The synthesis process was carried out at a
temperature of 80oC for 10 minutes. The analysis of UV-Vis spectra found that the most stable silver
nanoparticles were synthetized using a mass ratio 1:7 with maximum wavelength absorbtion which is
characteristic of the formation of silver nanoparticles at a wavelength 424 nm. 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 37,46o
(111), 41,64o (200), 60,49o (220) dan 72,51o (311). SEM characterization indicates that the silver
nanoparticles had a morphology of nanofibers and show that sample is still aggromerated. In addition,
the presence of Ag was comfirmed by EDX spectrum of sample that observed 15,86%. In 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 6 hours resulted in degradation values of 86.13%.
Key words : Bioreductor, Silver Nanoparticles, Ketapang Leaf, Methylene Blue.
