Pendekatan Konsep Lean Manufacturing untuk Meminimasi Waste pada Sistem Produksi (Studi Kasus PT. XYZ)

Abstract

Every company wishes to provide the best possible service to their customers by

delivering their products on time, for which quality and production lead time are the key factors

that need continuous improvements by way of adopting the right internal strategy. This research

applies the concept of lean manufacturing to identity wastes along the value stream to find out

non added value activities. In the initial stage, Big Picture Mapping is used to describe the

whole stream entirely, than Process Activity Mapping is used to find value added, non value

added and necessary-but-non-value added activities, whilst Quality Filter Mapping is used to

find the defects of the quality of defect type. In the last stage, Total Product Maintenance

(TPM) is applied to minimize defects by means of Overall Equipment Effectiveness (OEE). The

OEE Sensitivity analysis is applied to the operating time, cycle time and defects to find out the

most influential factor for the improvement of OEE. The result of this research has identified

cycle time as the influential factor that affects the OEE value. The 10% decrease in cycle time

will improve OEE by 10,20%
