Ajinomoto Mojokerto using the SWAT method. The method used in this study is the SWAT method. The SWAT method is a method of measuring mental load subjectively based on worker perceptions, using a combination of three dimensions with their levels. These dimensions are time load, mental effort load and psychological pressure load. SWAT as a multidimensional scale carries out 2 (two) stages of work, namely: making a scale and giving values ​​to the research results. Testing of questionnaire data using the Anova Test resulted in a probability value of 0.213. Because the probability value is greater than 0.05, the data states that there is no significant difference in workload on work shifts. It can be concluded that the average mental workload of the morning shift, afternoon shift and night shift only differs by 19%, and to be precise, the night shift workload is higher than the morning shift and afternoon shift workload.
