SUMMARY
Hyacinth (Eichhornia crassipes) is one of the plants that can has the potential to be used as a deterrent to particle agglomeration for photocatalyst synthesis in wastewater treatment. In this study, catalyst ZnO/Bentonite using hyacinth plant extract (E.E.G) have been synthesized by carrying out the reaction between ZnCl2, KOH, bentonite and water hyacinth extract functioning as template using precipitation method. The composite was characterrized by X-ray diffraction (XRD), Fourier transform infrared (FTIR) and diffuse reflectance-Ultraviolet (UV-DRS). The XRD results indicated that the crystal sizes of ZnO and ZnO/Bentonite-EEG composites of variation bentonite 1 ; 5 and 10 g are 45.47 nm; 15.961 nm; 23.397 nm and 3.981 nm. The characterization using UV-DRS showed that the composite had a smaller band gap 1.98 eV compared to ZnO. The ZnO and ZnO/Bentonite-E.E.G composites are applied as catalysts for the degradation of methylene blue. The optimazation process was conduted by the variation of irradiation time, composite mass and methylene blue concentration as well the type of composite. The optimum degradation was 92.01% obtained in the initial concentration of metylene blue 10 ppm variation of composite ZnO/Bentonite-E.E.G 10 g at a mass of 100 mg within 105 min.
