Proposed Strategies for Improving Productivity in the Wagon Painting Process Considering the Worker's Health Level

Abstract

Productivity can be expressed as the quantitative relationship between the output generated and the input utilized. The evidence of high worker productivity signifies the workforce's capacity to meet the company's production targets effectively and efficiently. As one of the inputs in the production process, the workers must have proper physical, mental, and social health conditions to carry out their work activities well. A developing train manufacturing company in East Java has several stages of the production process, one of which is the painting process. Chemicals are supposed to be a potential hazard in the painting process, which can harm workers' health, primarily if the work is carried out over a long time. Health issues resulting from exposure to spray paint and the failure to meet production targets indicate the need for in-depth investigation. Therefore, this research aims to determine the effect of health on worker productivity and design strategies for improving worker's productivity. The methods employed are the Work Limitation Questionnaire (WLQ) and Time and Motion Study. The findings indicate that there is a partial relationship between time management and productivity. It is critical to put out recommendations aimed at minimizing the duration of paint exposure experienced by workers. The proposed strategies demonstrate the capability to decrease the standard time required for the flat-top wagon painting process by 1.11 hours (41.11%). This improvement is achieved by reducing the number of work motions from 20 to 14, and finally, productivity is improved by 3.6.
