Abstract

Increasingly fierce industrial competition requires companies to continuously improve the quality of their products to meet customer expectations and maintain competitiveness. This research was conducted at PT XYZ, a manufacturing company that produces Bottled Drinking Water (AMDK), with a focus on cup packaging products. The purpose of this research is to identify the types and causes of product defects, and formulate a quality improvement strategy using the Six Sigma method based on the DMAIC (Define, Measure, Analyze, Improve, Control) and Quality Function Deployment (QFD) approaches. The observation results show that the dominant types of defects are frosted cups, mushy cups, striped cups, and cup sizes that exceed the standard. The Defect per Million Opportunities (DPMO) calculation shows a value of 5.755 with a sigma level of 4, which means that the production process still requires significant improvement to achieve the Six Sigma target. Through the QFD stage, customer requirements are translated into technical characteristics that form the basis for the development of the House of Quality (HoQ). The results of this study provide a quality improvement strategy that is more structured and oriented to customer needs, and can be used as a reference for continuous improvement in the mineral water industry.

Abstract

Many sellers of goods through digital platforms (marketplaces) do not have large storage space, so currently logistics companies also provide warehouse services to store goods from these sellers. A good warehouse management system (WMS) must be able to flow goods from input to output effectively and efficiently. Many logistics companies have yet to comprehensively measure key performance indicators (KPIs) for their WMS due to the perception that measurement is difficult and should only be performed by experts. This study aims to design and measure the KPIs of a WMS. This study uses a case study approach in a logistics company that has a storage area for various types of goods from sellers. Data were collected through literature studies, observations, and interviews. The methods used were the Analytical Hierarchy Process (AHP) and Snorm De Boer. The results show that three KPIs fall into the poor category, including: putaway per man-hour, % location and cube occupied, and order lines picked per man-hour. The company needs to create a structured system for storing goods based on their type, set standard storage time limits or even increase storage capacity, and also need to monitor the smooth flow of goods. In the end, it is hoped that all proposed KPIs can be measured periodically for continuous improvement.
