INCREASING OF THE EFFECTIVENESS TIME AND AVOIDING THE CUMULATIVE TRAUMA DISORDER (CTD) RISK IN BUSHING ASSEMBLY LINE BY DESIGNING SUPPORTING TOOLS IN PT. SINTRA SINARINDO ELEKTRIK

Abstract

This research is focus in the Bushing Assembly Line. Bushing assembly line is a workstation that assemble bushing. There are two problems which are, the operator assembling bushing manually. Which mean the operator hold the bushing load on his left hand while the right hand assembles the bushing. Because of this, the operator feels fatigue and keep on resting and causes inefficient time and ineffective movement. And if the operator keeps on holding the bushing for a long time, the operator will face the risk of cumulative trauma disorder (CTD) on his left hand. Because the load of the bushing is around 3 until 4 kg. The objective of this research is to increasing the effectiveness time and movement in the bushing assembly line and also to avoid cumulative trauma disorder (CTD) risk on the operator by creating a supporting tool in bushing assembly line. The method that is used in this research are Lean Manufacturing, ergonomic, motion study, and quality function deployment (QFD). After using the supporting tool, the efficient time increase and some of the ineffective movement has been eliminated and decreased and also by using the tool, the operator no longer feel fatigue on his left hand.
