Research on the modification of electrooptic instruments has been carried out. This study aims to design a digital-based automatic polarization angle measurement system that can be applied to determine the quality of cooking oil. The optical properties used as indicators to determine the quality of cooking oil using the polarization angle are relatively small, so a tool that can measure accurately is needed. A digital analyzer has been used with manual intensity determination, so that parallax errors can occur. In this research, an automatic polarizer will be made to determine the quality of cooking oil. The tool uses a light sensor as a minimum intensity detector and a stepper motor as an actuator which is connected to an analyzer using gears and uses Arduino due as a controller and data processor. The test results show that measurements have an accuracy of 0.033% in the malus law test. In the application of a tool to determine the quality of cooking oil, the results show that the change in the polarization angle for expired cooking oil is greater than the polarization angle for unexpired cooking oil.
