COMPARATIVE ANALYSIS OF WORK EFFICIENCYMEASUREMENTS IN THE WIRE HARNESS INDUSTRY

Abstract

PT XYZ is a company engaged in the wiring harness assembly industry that supplies
products to automotive companies in Indonesia. The product of this company is a
variant of the part number wiring harness, each of which has a different processing
time and employee needs in the assembly process. In the production process for Part
No 22-66779-00, PT XYZ divides the work line into three parts, namely the head
assembly process (assembly of the product head), the body (assembly of the product
body), and the end (assembly of the product tail). The work is conducted based on
these parts by many manpower. The problem is that because social distancing is
applied, work efficiency in each production line becomes less than optimal. Work
productivity decreases and the finished product is past its delivery deadline. In this
study, we analyze two scenarios of assembly work on wire harness products. The first
scenario is to assemble the head, body, and end separately as PT XYZ has done in the
field. While the second scenario is to assemble the heads separately and then carry out
the assembly process with the assembly results from the body and end lines (mix body
and end). It is resulting in a more efficient assembly process with a lack of time used.
The transformation makes improved total time in all the activity processes faster in
2756.38 seconds. The productivity has an increase of 10% than using scenario 1.
