Analysis of the Utilization of Refractometer Tools to Test the Quality of Cooking Oil

The study of optics in the industrial field in everyday life is the use of a refractometer to test the quality of cooking oil. The purpose of this study is to analyze the use of a refractometer to test the quality of cooking oil. The variables used are in the form of data from experiments that have been carried out previously by researchers. Tested oil of several different types and brands. The experiment uses the principle of light refraction and uses the value of the refractive index to measure the quality of cooking oil. Data collection is done through a review of journals related to the theme of the article. The results obtained in the form of a large refractive index value indicate that the quality of the cooking oil is poor and vice versa. A small refractive index value indicates that the quality of the cooking oil is good.
