This study aimed to synthesize PPy membranes using polyphenol oxidase (PPO) isolated from white oyster mushrooms as a biocatalyst for processing textile wastewater. The membranes were produced through the electropolymerization of pyrrole (Py) using the electrodeposition method. The raw materials comprised 0.05 M Py and crude PPO white oyster mushroom extract at 35% v/v in citrate buffer pH = 6.8. The electrolysis process was performed at 6.00 V and 1.063–1.142 A using 16.57-48.97% immobilized PPO in PPy, PPO activity of 1.640–4.160 U, and 0.35 mM phenol as a substrate. The results showed that the use of the membrane in textile wastewater with a discontinuous flow caused a decrease of pH by 14.86%, phenol by 6.80%, Chemical Oxygen Demand (COD) by 81.30%, Biological Oxygen Demand (BOD) by 78.25%, and Total Suspended Solids (TSS) by 20.65%. Meanwhile, using the sample with a continuous flow caused a decrease of pH by 23.97%, phenol by 26.09%, COD by 88.50%, BOD by 78.00%, and TSS by 65.70%. The physical performance of membrane application to textile wastewater with discontinuous (flow rate = 48.19–51.50 L/h, flux = 3191.6–3387.5 L.m -2 .h -1 , and permeability = 319.2–338.7 Lm -2 .h -1 .bar) and continuous flow (flow rate = 48.19 L/h, flux = 3191.6 Lm -2 .h -1 , and permeability = 319.2 Lm -2 .h -1 .bar) was also assessed in this study. The Scanning Electron Microscopy (SEM) image was used to assess the morphology of the membrane before and after its application.}, issn = {2597-9914}, pages = {83--90} doi = {10.14710/jksa.27.2.83-90}, url = {https://ejournal.undip.ac.id/index.php/ksa/article/view/59928} }
