Minimize inventory deviations in the Konimex technical warehouse through the implementation of the DMAIC concept

Abstract

PT Konimex is a manufacturing company that focuses on the pharmaceutical sector and is supported by an Engineering warehouse for machine maintenance during operation. However, during its run, there were problems in the form of discrepancies between the stock stored in the warehouse and those recorded in the company’s system which had a negative impact in the form of losses for the company. Therefore, a step-by-step analysis is carried out to provide solutions that are in accompanying circumstances using the DMAIC (define-measurement-analyze-improve-control) concept. The data collection method carried out is carried out directly and produces data in the form of primary data and indirect data collection, which uses the company’s historical data and produces secondary data. Data processing using the DMAIC concept then obtained the root of the problem and improvement solutions in the form of container redesign and the application of 5S as well as the addition of warehouse personnel which is expected to reduce the company’s stock-taking discrepancies.
