Abstract

This study aims to determine the effect of the composition comparison of the PVA-Enzyme urease coating PVC-Plastisizer KTpClPB membrane with memmbran characterization using FTIR and analyze membrane electrodes with XRD. The method used is the potentiometric method using the Electrode Selective Ion (ISE), where the polymer used is PVA and PVC as a coating with a composition ratio of PVA: PVC is 1: 1. The same PVA and PVC were used, namely 0.0350 g, with 2 mg of enzyme and 0.0500 g and 0.0120 g of KTpClPB plasticizer. The best composition result is the PVA-Enzyme PVC-Plastisizer coating enzyme KTpClPB 0.0500 g membrane electrode characterization using XRD shows the highest intensity value is at an angle of 2θ = 44.020 which is 1,626 count second (cts) and membrane characterization using FTIR shows that there is a functional group OH, CH, C≡C, NH, CO and CH. The addition of PVA-Enzyme coating will reduce or even eliminate the amount of Wolframm and can reduce the amorphous properties of the membrane electrodes.
