Abstract
The objective of this research is to increase the efficiency of the rotor assembly line by reducing machinery downtime. This is mainly due to procedures for startup and inspection that occur every day together with inappropriate working positions by applying 7 QC tools, production line balancing, and plant layout to analyze and improve the production process. From the implementation of the proposed method, it was found that the machine downtime can be reduced from 24.14 minutes to 10.76 minutes, equivalent to 55.43%, resulting in an increase in the production of 10,512 pieces per year. Moreover, the efficiency of the startup work and inspections process, increased from 41.53% to 63.62%, resulting in the machine utilization rate increasing from an average of 75.62% to 80.13%.
