Work Shift Analysis by Using Psycho-Physiological Method

Abstract:

This paper presents a study of work shift analysis on security workload. Six security employees were investigated in this study for two work shift periods (morning and night). T - test was used to determine the differences of psychophysiological fatigue before and after working. Survey was conducted to identify some complaints. Pulse, blood pressure (systolic and diastolic), and skin temperature were also determined to define the physiological fatigue. In addition, motivation, psycho - social, and psychological complaints were identified to define the psychological fatigue by using an independent developed questionnaire. The results then shows some differences about the physical fatigue aspect in which the average are 32,2 before working and 28,2 after working. The average pulses aspects are 65.6 beats/min and 93.2 beats / min before and after working, the average blood pressure are 121,8 mm Hg and 127,7 mm Hg before and after working for systolic aspect. The average blood for diastolic aspect are 71 mm Hg and 75,9 mm H before and after working. Skin temperature is 34.8 C before working and 34.6 C after working. Result of this study also shows some differences on psychological fatigue where the mean work motivation was 21.5 before working and 24.7 after working, psycho-social was 13,5 before working and 14.3 after working, and psychological complaint was 50.8 before working and 40.83 after working.
