Abstract

Jaya Abadi Motor Workshop business does motorbike servicing work with bad working postures, which are standing while bending, sitting, and squatting, causing muscle injury(Musculoskeletal Disorders) for 4 mechanics. For this reason, it is necessary to design a work facility for efficient motorbike service. The Nordic Body Map (NBM) questionnaire was used to find out the percentage of body parts that experienced no pain, sufficient pain, pain and evaluation. With NBM comparisons before and after, this will be a reference to improve operator work posture for the better. The results of the design of the tool in the form of a motorcycle lift that is useful to position the height of the motor as set with the needs of the operator (calculation of anthropometry with 5% percentile of 855 mm from the ground), there is a dynamo as an additional automation of the propulsion and there is still a hydraulic lever for backup when the dynamo switch is broken , so that helps in the process of setting the motor high and low. Based on testing the NBM results are lower (down 50% and partly down 25% from 100%), so that the working posture is better and the facility can be utilized to service motorcycles only for the type of motorcycle.

Abstract

The high number of product defects in the manufacturing industry has a significant impact on the products quality and productivity of the enterprise. The research was conducted at manufacturing companies that produce drums, pail cans, and other can packaging. In the production process, they found a high defect rate in the drum production process, which resulted in a decrease in the quality and productivity of the factory. This research is aimed at assisting companies in reducing the defect rate of drum production; improving process efficiency; providing proposed process improvements; and minimizing existing waste. This study used the Lean Six Sigma approach, using SIPOC and CTQ to define problems, and measure process efficiency and product quality, obtaining a process cycle efficiency value of 8.06% and a sigma value of 4.6%. Based on the pareto diagram, the dominant defects are abrasions, paint top/body damaged, and screen printing top/body damaged, while based on WAM, the dominant defects are defects, inventory, and waiting. Based on this stage, analysis was carried out on all three defects using fault tree analysis, why-why analysis, and FMEA. In the future, improvements will be implemented to reduce the number of defects and increase productivity so that there is an increase in the value of PCE of 9.23% and a sigma value of 5.04 after improvements.
