Abstract

This research has developed some jig designs for plug assembly line. The design is based on number plugs per jig (3 or 4), orientation of jig design (vertical or horizontal) and screwing process (no flip or flip). To find the most efficient design of jig, an experiment has been conducted based on Design of Experiment. Design of experiment 24 with two levels of each factor is used. Two subjects were employed to conduct the plug assembly experiment. 36 experiments for each level of factors were conducted and each subject conducted total 288 for 8 different sets of combination factor. With using Analysis of Variance (ANOVA) the most efficient design were identified. The results shows that number plug per jig in this research have most significant effect to the assembly time. Orientations of jig design and screwing process also show have significant effect to assembly time. Interaction combinations of two and three factors do not show any significant effect to assembly time. The most productive with lowest assembly time achieved at factors: number plugs per jig are 4, orientation of jig design is vertical and screwing process is flip.
