dc.description.abstractBioactive chemicals in Rhizopora mucronata barks can be exploited in the production of silver nanoparticles. This research aims to ultilize aqueous Rhizopora mucronata bark extract in the preparation of silver nanoparticles, the optimum pH in the silver nanoparticle synthesis step will be determined and characterized. The bioactive chemical predicted to work as reducing agent that will reduce Ag+ to Ag0. The silver nanoparticles synthesized were carried out using 9 mL AgNO3 in 1 mM concentration added 1 mL extract and then incubated for 25 minutes in the optimum pH. The results showed that a optimum pH for the silver nanoparticles synthesized using aqueous extract of Rhizopora mucronata bark is pH 9. Based on UV-Vis spectrum, the peak was shown at 422 nm with 1.866 of absorbance. Alkaloids, tannins and saponins compounds are secondary metabolite that interact as reducing agents in Rhizopora mucronata barks. X-Ray Difraction (XRD) analysis showed that the silver nanoparticles resulted were crystalin and detected with Face Centered Cubic (FCC), average size 23.33 nm and Scanning Electron Microscopy (SEM) analysis showed the surface morphology has cubes shape with homogen distribution and size of area surface in average of 21 nm. It can be concluded that aqueous extract of Rhizopora mucronata bark are potentially used in silver nanoparticles synthesis at optimum pH 9.en_US
