One method in the field of physics to determine the quality of cow oil and palm oil is to use changes in the angle of light polarization from electro-optical properties. This research uses a green diode laser light source with a wavelength of 532 nm. The sample which had been heated for 2 hours, 4 hours, 6 hours, and 8 hours was applied at a voltage from 0 to 9 kV to obtain an electrooptical effect in the form of a change in the polarization angle ?? as a function of the voltage V. The results of the study showed that the relative dissociation energy would decrease due to heating the sample because triglyceride molecules would continue to form so that the molecular bonds became loose and the angle rotated. polarization. Palm oil has a dissociation energy that is relatively greater than animal oil, and increases after the sample is heated. It is concluded that electrooptical effects can potentially be used to obtain relative dissociation energy as a single parameter in distinguishing various oil qualities. This method can be further developed on other materials and provides good prospects as a preliminary test to determine oil quality.
