  • Molecularly imprinted polymers (MIP) is a technique to produce a polymer having cavities as a result of the removing of specific template. MIP endosulfan is MIP with endosulfan template, one of pesticide types. MIP can be applied to the electrodes. This study aimed to obtain optimum conditions of MIP endosulfan manufacture with cooling and heating methods, characterize MIP endosulfan using SEM, and test the performance of aluminum-carbon-based electrodes MIP endosulfan as a potentiometric sensor. Stages of generating electrodes of MIP endosulfan were MIP endosulfan generating, MIP endosulfan coating on the surface of the aluminum-carbon electrodes and electrode potentiometric testing. The obtained MIP endosulfan by washing and without washing were characterized using SEM. The results showed differences in the number of pores between MIP without and with washing. The test results of electrode performance indicated that MIP endosulfan-based aluminum-carbon electrode as sensor had detection limit of 0.02 mM, sensitive in the concentration range from 0.02 to 0.12 mM with Nernst factor> 0.059 V / decade and had good stability and repeatability.
