Abstract
In a study chair assembly workstation facility at Industrial Engineering Design Practicum 2 (IEDP2), practicum students experienced difficulties, including rotating fixtures, separating bolt and nut components, and changing assembly positions. Kinetics analysis through evaluation of work postures is needed to redesign assembly stations. This paper compares the before and after redesigning of a study chair assembly workstation in IEDP2 based on work posture with kinetic analysis through 3D motion with Kinect and LightBuzz Vitruvius sensors. As many as 20 students were involved, including practicum assistant students and practicum students at the Laboratory of Product Planning and Design (LPPD). Comparison of assembly workstation redesigns was measured using fair and maximum moments, testing through paired t-tests. The significant differences between before and after redesigning a study chair assembly at workstation facilities were statistical (p < 0.001). Kinetic analysis showed an increase in improving students' working posture by redesigning workstation facilities, showing a different workload on the upper limbs when assembling.
