  • Electrolyte solutions used in potentiometric cells from ion-selective electrode (ISE) sensors urea contribute to a good enzymatic reaction. This study aims to obtain electrolyte solutions that have the best response to ISE on the electrode modification membrane electrode 35 mg PVA-enzyme coating 35 mg PVC-500 mg KTpClPB. Solution analysis begins with the characterization of ISE electrode membranes using UV-vis, SEM-EDX, and XRD, the best results on electrode membranes are used as ISE. Analyzing the solution sequentially is a phosphate buffer solution, KCl phosphate buffer solution and phosphate buffer KCl injection with urea using a potentiometer, power lab, and computer to see the solution response. Based on the results of the computer response obtained a phosphate buffer solution pH 5.5, 0.001 M, 0.001 M KCl, and 0.001 M urea.
