NOISE-INDUCED WORK STRESS DURING A TRAIN OPERATION

Abstract

Train is a transportation that produces a high level of noise. Cabin crew as a person who work on the train will always be exposed to noise and have a greater chance to get work stress due to noise that will affect his work so that it can endanger passengers and the occurrence of train accidents. This study’s objective is to determine the impact of noise level toward work stress of cabin crew KA Kaligung Loco CC 201 DAOP IV Semarang. Noise level was measured using Noise Dosimeter and work stress was measured using DASS 21. The relationship between variables was analyzed using SPSS program with chi square method. Respondents were taken 30 cabin crew of KA Kaligung Loco CC 201 and as a comparison were taken 30 workers of Station Pocol as control variables. The result shown that there is a correlation between the increase in work stress level with noise (sig ,000). Based on noise sampling with case control methode for 3 days at KA Kaligung Loco CC 201 produces a noise value above the threshold 87 dBA during 4 hours 47 minutes that is 88 dBA, 93 dBA and 90 dBA. Station’s noise level as control is 74,78 dBA and this is result in under the threshold 85 dBA during 8 hours. While the average increase on cabin crew’s work stress reached 3,6 point. Whereas, Station Poncol’s workers have decrease work stress level until 3,3 point, From 30 cabin crew there were 26 respondents experienced an increase in work stress level, 3 respondents experienced a decrease in work stress level and 1 respondent had a constant stress level.
