Abstract

This study is about the industry that produces wooden doors for export needs. The problems is the occurrence of defects in the production process and non value-added process. Type of defect commonly found on the wooden door is the assembly, gluing and coloring. This study aims to improve the quality of doors produced by reducing the number of defect products and reduce waste in the production floor. Lean Six Sigma is used to focus on reducing lead time and failure in the production process. Result shows that the main cause of defect products is low skill operators and machine during operation so that the product does not comply with the specified quality, The proposed improvement is to provide job training for operators, machine maintenance plan and make the procedure of operation activity on the Laminating, Glazing and assembly.

Abstract

This research addressed the issue of the PT. XYZ production line balancing which produces powder and ceramic. The completion time of the production line is important because there are differences in the capacity of the machines, especially on powder machine and press machines. This approach is done by using the Helgeson and Birnie method by considering the activities processing time on the production floor. This method increase Balance Delay of powder process at point 0.3333 and Balance Delay of ceramics process in Press A1 and A2 in the Press is 0.1968 and 0.2185. The level of powder process efficiency is 65.82%, while level of powder process efficiency is in Press A1 is 80.31%. The level of efficiency in the production of ceramics in Press A1 is 74.07%
