Productivity improvement by fundamental of hand motions : a case study of assembly line in an electronics company

Abstract

The purpose of this research is to study productivity improvement at electronic parts’s assembly line, finding the work stations with work station time longer than takt time. This research applied the 5W1H technique as a tool to problem analysis, fundamental of hand motions to improve productivity. The study found that the assembly line consisted 15 work stations and a cycle time of 12.0 seconds which greater than the takt time, which was 10.5 seconds. The work station time no.6 took longer than the takt time. The fundamental of hand motion technique was applied. By separating or eliminating, the fundamental of hand motion did not affect the performance of the work stations. By being integrated the fundamental of hand motion with previous work station or next work station. As a result of research is the new cycle time of this production line is 10.0 seconds, the production line capacity increased from 300 pieces per hour to 360 pieces per hour , 20 percent increase
