ANALYSIS RELATIONSHIP OF NOISE AND HOT WORK CLIMATE WITH FATIGUE OF WELDING WORKERS ON INFORMAL SECTOR (STUDY CASE : BOGOR STREET WELDING STALLS, BANDUNG)
Fatigue is a condition when a worker feels tired physically or mentally. Fatigue can be caused by several factors such as physical factors of the work environment factors like work climate and noise, determining factors in workers such as age, nutritional status, medical history, smoking habits,...

| Summary: | Fatigue is a condition when a worker feels tired physically or mentally. Fatigue can be
caused by several factors such as physical factors of the work environment factors like
work climate and noise, determining factors in workers such as age, nutritional status,
medical history, smoking habits, sleep quality, marital status, and amount of drinking
water consumption, or occupational factors such as work duration and years of
service. One of the jobs that exposed to hot working climate and noise is welding. Jalan
Bogor welding workshop is one of the center of welding workshop industry in Bandung
City. The purpose of this research is to identify noise and hot working climate level in
Jalan Bogor welding workshop, then to determine its relationship and risk factors to
work fatigue. This research conducted on 4 groups of welding types, there are electric
welding, plasma welding, acetylene welding, and iron cutting. The research method
used a cross-sectional design. The data collection method was done by distributing
IFRC (Industrial Fatigue Research Committee) questionnaire as a measurement of
fatigue levels with the number of samples used in this research were 50 workers using
random sampling method, noise intensity measurement using Sound Level Meter (SLM)
in the morning, afternoon, and evening, and hot working climate measurement with
QUESTemp in the afternoon because that is the time when the workers feel the hottest.
Then, all datas were analyzed descriptively and statistically with chi-square test, and
multiple linear regression. The result showed that hot working climate (p=0,004),
noise (p=0,019), nutritional status (p=0,025), sleep quality (p=0,004) and the amount
of drinking water consumption (p=0,023) have a significant relationship with the
incidence of work fatigue and are included to risk factors of work fatigue. The results
of F test using multiple linear regression showed that the physical factors of work
environment, host factors, and work factors had a simultaneous influence on fatigue. |
