Abstract

Effective planning to manage the procurement of raw materials is crucial for maintaining productivity in production activities and controlling costs. Indonesian enterprise UD. XYZ is dedicated to the manufacturing of fried onions. However, between April 2022 and June 2023, there have been regular fluctuations in the raw material availability for the production process, which has resulted in subpar output levels and unmet demand. To solve this problem, this study will use time series forecasting techniques to estimate the demand for fried onions and the Economic Order Quantity method to control raw material supply. Furthermore, this study uses the Just In Time approach to determine the minimum inventory cost. Both systems are anticipated to lessen the effects of changes in raw material availability. Based on the research results, the linear regression method was used for forecasting, which predicted an average demand of 1354 Kg of fried onions with a MAPE value of 2,79%, MAD 27,59, and MSD 1317,81. Then, an EOQ value of 1992,85 kg was calculated using the Economic Order Quantity (EOQ) and Just In Time (JIT) methods. This resulted in a total minimum storage cost of Rp. 2.989.271.

Abstract

There are shipyard industry companies that provide measuring instrument calibration services. In 2022, the calibration service experienced a decline in marketing and a lack of external market segments compared to internal ones. This research aims to identify the factors that contributed to this decline, analyze marketing strategies using the SWOT analysis approach, and prioritize calibration service marketing strategies using the AHP method. The results of the SWOT analysis revealed four alternative strategies: SO (Strength-Weakness), WO (Weakness-Opportunity), ST (Strength-Threats), and WT (Weakness-Threats). In the IFAS and EFAS matrix, two influential factors were identified: licensing to enter the calibration laboratory location, which involves too much bureaucracy and makes customers hesitant to return (score of 0.45), and damaged calibrator standards that may lead to the suspension of calibration scope (score of 0.70). Based on the hierarchical structure, the AHP method prioritized the WT strategy with a weight of 5.11. This strategy includes conducting periodic checks, forecasting the calibrator to ensure good maintenance, and establishing cooperation with agencies that require calibration services. These prioritized strategies aim to increase sales and improve the marketing of calibration services for shipyard industry companies.
