Abstract

Workload can be defined as the difference between a worker's ability and job demands. Based on observations that have been made, it is known that madukismo sugar companies get an increasing demand value in each season of production, so this causes an increase in the number of working hours that apply to the company, which has the potential to increase their mental work. This study investigated the mechanical mental workload of workers at Madukismo Sugar Company using the NASA-TLX method, a multidimensional assessment tool. The NASA-TLX method is a multidimensional assessment method that can measure the overall mental workload to determine the mental workload felt by each worker. The results indicate a very high mental workload in some operators and suggest the need for operational adjustments. The recommendations are additional manpower and improved ergonomic levels to reduce stress and increase productivity. Keywords: Mental Workload, NASA-TLX, Job Demands

Abstract

PT. Bakrie Autoparts produced BT-1804 products for 12 months, and of the 9537 units produced, there were 3572 product defects with various types of defects. Therefore, Six Sigma with DMAIC is used to minimize defect problems. In stages, define used Critical to Quality (CTQ), where 16 types of potential defects were found in the BT-1804 product. At stage Measure, the Pareto diagram measures the highest frequency of defects and the improvements needed. At stageAnalyze used the Fishbone Diagram, where this method focuses on repairing 1 type of defect in BT-1804, which is the type of machining defect that is the dominant defect. At stageImprove, correcting the root of the problem with FMEA (Failure Mode and Effect Analysis), where it was found that inaccurate machine settings had the highest RPN value of 100. So, suggestions were given by providing knowledge in the form of training related to production mechanisms and providing supervision of operator performance during the machine setting process. Keywords: Quality Improvement, Six Sigma, DMAIC; Failure Mode and Effect Analysis
