Mental stress can stem from uncontrolled physical demands, environmental factors, and social situations. In academic environments, this stress often impacts student performance, notably during lecture activities. This study aims to analyze the mental workload experienced by the 2020 class of Industrial Engineering students at a private university. Its goal is to identify factors contributing to students' mental workload and propose suggestions to address these challenges. The Subjective Workload Assessment Technique (SWAT) was utilized to assess mental workload through respondent evaluations. Additionally, a Fishbone Diagram was employed to pinpoint factors leading to increased mental workload in students. Questionnaires were distributed to all students enrolled in at least 18 credits during the odd semester of 2022-2023. The findings indicate that students of the 2020 class experience mental burden during both class and practicum activities. Specifically, class activities accounted for 46.78% in the time dimension and 25.77% in the effort dimension, while practicum activities accounted for 55.34% in the time dimension and 20.39% in the effort dimension. Stress levels were recorded at 27.45% for class activities and 24.27% for practicum activities. The analysis identifies various stress-inducing factors in teaching and learning activities, including challenges in studying quiz and practicum materials, active participation in practicum activities, completion of practicum reports, and effective communication with practicum partners. To address these challenges, several recommendations are proposed, such as restructuring lecture schedules, equitable distribution of assignments and quizzes throughout the semester, fostering effective time management, aligning credit loads with individual capacities, among other strategies.
