Abstract
Computer-based Test (CBT) is a form of assessment method using a set of Multiple Choice Questions (MCQs). CBT has been applied by many educational institutions to evaluate their student’s competencies, one of those institutions is medical school. The standard of the CBT examination in medical school is arranged according to the Indonesia Medical Licensing Examination which listed that the examination must be contained of 200 MCQs in 200 minutes without a break session. This standard causes academic stress on the CBT participants and able to affect the CBT score. Aims: demonstrated the total ergonomic approach CBT redesign in reducing academic stress and improving participant’s CBT score compare with the Indonesia Medical Licensing Examination CBT design. Method: this was an experimental study employed a two-period cross-over design. The study variable was the academic stress measured by the salivary cortisol level and participant’s CBT score. Result: the salivary cortisol level in the middle of CBT was decrease significantly (p<0.05) as much as 9.88 (38.98%) from the initial salivary cortisol level of 25.34 ng/mL on the Indonesia Medical Licensing Examination CBT design becoming 15.46 ng/mL on the total ergonomic approach CBT redesign. The CBT score also increase significantly as much as 5.23 points (p<0.05) or increasing 16.20% from the 32.28 points on the Indonesia Medical Licensing Examination CBT design which become 37.51 points on the total ergonomic approach CBT redesign. Conclusion: the total ergonomic approach CBT redesign was able to reduce 38.98% of the academic stress and improving 16.20% participant’s CBT score compare with the Indonesia Medical Licensing Examination CBT design.

Highlights
Computer-based Test (CBT) is assessment method conducted by answering a set of Multiple Choice Questions (MCQs) in a computer workstation
The independent variables were the Indonesia Medical Licensing Examination CBT design and the total ergonomic approach CBT redesign, while the dependent variable was the academic stress measured by the salivary cortisol level after the end of the CBT session on each period
Group 1 on the period I was participated in the Indonesia Medical Licensing Examination CBT design, while group 2 on the period I participated in total ergonomic CBT redesign
Summary
Computer-based Test (CBT) is assessment method conducted by answering a set of Multiple Choice Questions (MCQs) in a computer workstation. The redesigning of CBT in UNIZAR medical school with the total ergonomic approach consisted of re-setting the workstation computer brightness according to participant brightness preference This modification can decrease the level of fatigue and improve the focus during the CBT examination. The redesigning of the CBT in this study were including some aspects, they were (1) modifying the explanation before the CBT session by motivating the participant to take enough rest before the examination, (2) manage an ergonomic posture during the examination, and (3) doing 15 minutes active stretching on the break session. This is required to decrease the musculoskeletal and fatigue complaint after the CBT examination. This could be done by redesigning the CBT using the total ergonomic approach
