This research aims to investigate&nbsp; effect of variation radiation times, pH, and concentrations doping PEG (polyethylene glycol). The absorbance of samples was measured by a UV-Vis spectrophotometer. The result showed maximum time of irradiation to degradate methylene blue at 120 minutes, with&nbsp; percentage degradation is 94.55%. The effect of pH showed maximum pH at 7 with&nbsp; percentage degradation is 96,83%. Meanwhile, the effect of variation concentration doping PEG showed maximum result at ZnO-PEG 15%, with percentage degradation is 87,12%. Sample was characterization by&nbsp; XRD, FTIR and UV-DRS. The XRD pattern showed&nbsp; wurtzite (hexagonal) structure and has crystal size of 47-88 nm. FTIR spectrum showed that 425,33 cm<sup>-1</sup>&nbsp; vibration strain for Zn-O. Analysis UV-DRS obtained band gap value is&nbsp; 3.19 eV.</p>}, number={02}, journal={EKSAKTA: Berkala Ilmiah Bidang MIPA}, author={Sanjaya, Hary}, year={2017}, month={Nov.}, pages={21-29} }
