Abstract

The management of packing material inventory in flexible packaging often faces high investment value, inaccurate demand planning, and inefficient ordering, creating a research gap in selecting an integrated optimization method. This study aims to determine material requirements and optimal order quantities to minimize total inventory cost. The methodology integrates ABC Analysis for material classification, forecasting techniques to predict demand, and Economic Order Quantity (EOQ) to determine the most economical order size. The results show that Plywood is classified as category A due to its dominant investment value. Forecasting evaluation using MAPE and Tracking Signal indicates that the 3-period Weighted Moving Average provides the highest accuracy with the lowest error. The EOQ calculation produces an optimal order quantity of 3,304 units for Plywood Multi 0280x0280x09 dia 77, significantly reducing inventory cost. The integration of ABC, forecasting, and EOQ improves inventory efficiency and supports more reliable production planning

Abstract

AbstractUD Darmaji is one of the SMEs that accepts orders for making sandals and shoes. In the last few years, UD Darmaji has experienced a decline in production, there are several causes for the decline in production from UD Darmaji, including the lack of demand and inaccurate formulation of marketing strategies in marketing strategies. There are several methods and analyzes used, namely SWOT analysis (Strength, Weaknesses, Opportunities, Threats), IFE matrix (Internal Factor Evaluation Matrix) and EFE (External Factor Evaluation Matrix) and AHP (Analytical hierarchy process) which is used for weighting and QSPM ( Quantitative Strategic Planning Matrix) to determine what strategies to choose. The results of the analysis show that the strategy of selling online using both social media and online buying and selling sites has the highest TAS (Total Attractive Score) value of 5,614, the strategy to improve the quality of the packaging is better and more attractive, with a TAS value of 5,336, and a strategy to make the workplace more comfortable by rearranging the factory so that it looks tidier and cleaner and implementing the 5R TAS value of 5.242, which will be used as a suggestion for UD Darmaji.
