Productivity Analysis Using the Objective Matrix and Fishbone Diagram Methods in SMEs of Airplane Replicas

Abstract

Aircraft Replica SMEs have never known the level of productivity achieved because they have not carried out productivity measurements and analysis. This study aims to determine the level of productivity, the factors causing the decline in productivity, and provide suggestions for corrective actions. The methods used are OMAX and fishbone diagrams. There are five productivity ratios used. Ratios 1 and 4 are dominated by a very large number of bad productivity ratios. The lowest total productivity achievement occurred in July at 0, while the highest total productivity achievement occurred in February at 601.13. The index value of change in the achievement of total productivity to the best standard productivity occurred in February at 100.38%, while the worst value occurred in July at -100%. The best index value of changes to productivity in the previous period occurred in August at 395.15%, while the worst value occurred in July at - 100%. Corrective actions include optimizing rest hours so that at work they can concentrate even more, optimizing working hours so that no working hours are wasted, increasing the comfort of the workplace, optimizing all employees so that the results obtained can also be optimal, ensuring that production results achieved are always controlled, and motivating employees by giving bonuses to employees who perform well.
