Evaluation of Machinist’s Fatigue at PT. Kereta Api Persero DAOP II Bandung

Abstract:

Machinists have a big
responsibility in controlling trains and maintaining the safety of trips. When
a machinist has an irregular work schedule, monotonous and long schedules, he
may experience fatigue while on duty. Fatigue can cause a decrease in
performance and lead the machinist to make mistakes that can later be the cause
of railway accidents. Fatigue assessments, then, become an important program
that can be used by management to improve railway safety. In this study, a
fatigue evaluation was conducted among 30 machinists working at the Indonesian
Railway Company (PT. Kereta Api Indonesia or PT. KAI). The evaluation consists
of assessing the quality of sleep with The Pittsburgh Sleep Quality Index
(PSQI), the measurement of subjective sleepiness with Karolinska Sleepiness
Scale (KSS), the measurement of secondary work performance with Psychomotor
Vigilance Test (PVT), and heart rate measurements employing a heart rate
monitor (Beurer PM-18). Results of this study showed that most of the
machinists experienced sleep quality problems. Also, the sleepiness level of
the machinists continued to increase at work and the reaction time was worse at
the end of his shift, although levels of physical fatigue were not substantial.
Suggestions were proposed to the management, including new work schedules using
shift rotations in order to reduce fatigue.
