Improving Ergonomic Work Attitudes Reducing of Musculoskeletal Disorders, Workload and Increasing Work Productivity of Pande Besi in Gubug Village Tabanan, BaliIndonesia

Abstract

One of the processes in the making household tools such as small knives, large knives, sickles, and machetes is a tool in the form of a gerida that weighs approximately 1.5 kg. Working on the floor with the base can cause several musculoskeletal disorders such as pain in the back, waist, neck, shoulders, buttocks, legs, and knees. The purpose of this study was to determine the effect of Ergonomic Work Attitudes in Reducing of Musculoskeletal Disorders (MSDs), Workload, and Increasing Work Productivity of Pande Besi in the Gubug Village of Tabanan. This study is an experimental study with treatment by subject design. The population is 40 people from 10 industries. Selection of sample using random sampling with a table of random numbers. The minimum sample size is calculated using the Colton formula so that the sample size is 16 people. Data processing and analysis: descriptive test for data on the subject's condition includes age, weight, height, and body mass index. The difference test for data work productivity was analyzed using a Wilcoxon test with α = 0.05, and the data MSDs and workload were analyzed using a paired samples t-test with α = 0.05) in Period I and Period II. The mean age of the subjects was 49.19 ± 12.24 years, body weight was 67,25 ± 7,10 kg, body height was 162,3 ± 0,07 cm, and the subject's body mass index was 25,48 ± 1,64 kg / m2. There was a decrease in musculoskeletal disorders by 18,37%, a decrease in workload by 34,6%, an increase in productivity by 47.06%. There is a significant decrease between musculoskeletal disorders, workload before and after the redesign (p <0.05), and a significant increase in work productivity before and after work attitude improvement
