Abstract

Carpal Tunnel Syndrome (CTS) is the most common neurological disorder of the hands due to the suppression or "squeezing" of the peripheral nerves through this tunnel with typical symptoms of pain, numbness and tingling in the wrist, thumb, index finger, middle finger and half of ring finger. Any use of the wrist causing narrowing of the carpal tunnel or increasing pressure within this confined space may result in CTS. In the construction sector, iron workers are daily workers who are tasked working on various ironing activities such as making columns. These workers are at risk of having CTS in their hands as a result of their job. The purpose of this research is to analyze the association between repetitive movement, wrist posture, work period and age with CTS incident on iron workers at apartment development by PT X. The type of this research is observational analytic research with cross sectional study approach. This research uses RULA to measure wrist posture, Phalen’s Test and BCTQ Questionnaires to find out and describe incidence of CTS. The population and sample in this study were 36 workers. Based on statistical test using Chi-Square, there was an association between repetitive motion with CTS (p value = 0,018), there was an association between wrist posture and CTS (p value = 0,006), there was no association between work period with CTS (p value = 0,688) and also there was no association between age and CTS (p value = 0,729) on ironworker who made columns. Some recommendation for company are to be able to educate workers working with a good posture and stretch their wrist after working. For workers, always keep the wrist in a neutral position more often, loosen the hand grip and reduce energy used when twisting wire and also stretching after work.

Abstract

Work fatigue can inhibit the work activities of employees of the production section because it results in decreased work power and reduced endurance to work. Preliminary survey results show that 70% of employees experience stiff complaints, 90% had heavy physical activity, 90% require high accuracy and 90% lack of rest. The purpose of this research was to analyze the correlation between individual characteristics, physical workload and mental workload on the employees of the production section at PT. X. This type of research uses quantitative methods, with cross-sectional studies. The population in this study amounted to 120 employees who work on the morning shift using the proportionate stratified random sampling technique obtained a sample of 45 employees. Work fatigue was measured using the Industrial Fatigue Research Committee (IFRC) questionnaire, physical workload was measured using a pulse oxymeter, mental workload was measured using a NASA-TLX questionnaire, nutritional status was measured using microtoise and weight scales. Statistical analysis used was the chi-square test and the Spearman rank test. The results showed that there was a significant relationship between physical workload (p-value 0.006), exercise frequency (p-value 0.021) and nutritional status (p-value 0.014) with work fatigue, there was no relationship between age (p-value 0.196), years of service (p-value 0.107), smoking habits (p-value 0.576) and mental workload (p-value 0.331) with work fatigue. Based on these results the researcher gives a suggestion that is stretching on the sidelines of work and doing exercise at least 3 times a week.
