Abstract

Work fatigue is a common problem in the work area, but it is often ignored in the interest of the company's smooth production. Uncontrolled work fatigue can have a negative impact on workers both physically and psychologically. In this study, workers were given a workload of up to 35 kg hours, often they worked overtime for up to 12 hours per day, causing work fatigue. The purpose of this study was to determine the category of work fatigue and the factors that affect work fatigue of warehouse workers at PT Nok Fredeunberg Batam Batam. The method used in this study is a subjective self-assessment test method, which can be used to measure the subjective level of work fatigue of the workforce. The results of this study are the fatigue category of warehouse workers at PT Nok Fredeunberg Batam is in the high fatigue category, followed by the moderate fatigue category. Spearman correlation test results show that working hours (sig = 0.00), workload (sig = 0.00) affect work fatigue. In order to be able to advise warehouse workers to carry out their duties or workloads in accordance with their physical abilities and work abilities, it is expected that there will be a break. Then it is hoped that the leadership of PT Nok Fredeunberg Batam Batam can add mechanical equipment to lift and move goods and rotate working hours ideally.

Abstract

In all industrial activities, the role of humans as a source of labor remains dominant. Unlike cars that can be repaired and replaced. Whoever is an employee still has limitations. In manual labor, people are at a greater risk of contracting MSD, which can lead to unsafe working conditions. Practice lifting a drink box in your CV. The AUDIO NEW LIGHT can be dangerous when lifting drawers due to manual and unsanitary working positions. The study has an average REBA occupational risk score of 8 in the high category for neck, back, waist, larynx, thigh, left arm, left and right wrist, right, indicating that immediate action is required. An approach to avoiding these risks when designing trolleys is to use EFD technology based on ENASE ergonomic considerations. The trolley element to reduce operator discomfort with its weight (0.306) is the highest priority in product development acquired by Efd, and above all, the target specification of the trolley created according to the anthropometric measurement of the operator is the highest priority for production. function. shoulder width (LB, Standing elbow height (TSB), and handlebar width are anthropometric data used for design (GT).

Abstract

ABSTRACT Many work error that occur are caused by human themselves, which are called human error. Human error that often occur in production activityes can harm thet company in achieving production effectivenes and eficiency. Therefore, it’s necesary to improve the performance of workers in order to reduce work error that often occur. Several methods for identifying human errors in clude the SHERPA and HEART methods. SHERPA is a qualitative human errors analysis method that uses task level as the basic input. HEART, on the other hand, is a quick, easy and accessible way to determine the risk of human error. PT Duta Logistik Asia is one of the companies that produces activated carbon in the city of Batam. The activated carbon process goes throuh several stages, namely the heating proces, the sieving process, and the packaging process. Based on the information obtained from the company, errors often occur when doing work which greatly affects the safety of workers and production output as a result of human error. Finding recommendations that are needed to reduce error in the activated carbon production proces using the SHERPA method are to carry out regular and thorough inspections and work on each process and provide periodic training to employees. The probability of error in every work activity in the activated carbon production process using the HEART method wherye the largest nominal human error probability value is 0.16. The process that may occur in human errors in the activated carbon production stage at PT Duta Logistik Asia is through the highest Human Error Probability (HEP) value of 0.544 which is found in the heating and packaging process of activated carbon.
