Abstract

Material inventory plays an important role in supply chain management because it affects the continuity of the production process and the quality of the products produced. The main problem faced by UMKM Rinjanni Ciamis is the high cost of inventory due to excessive ordering frequency. In addition, this UMKM has not implemented reorder points or safety stock as part of inventory control. One method that can be used to reduce total inventory costs is Economic Order Quantity (EOQ). The EOQ method is a mathematical approach that aims to determine the optimal order quantity so that total inventory costs, both ordering and storage costs, can be minimized. Based on the calculations, the total inventory costs of this UMKM using the conventional method were Rp 4.422.000, while the application of the EOQ method reduced the costs to Rp 278.795, resulting in savings of 94% or Rp 4.143.205. In addition, the EOQ method was also able to determine a safety stock of 258 kg and a reorder point of 790 kg, whereas in the previous conventional method, these two parameters had not been applied. Thus, the application of EOQ can improve inventory control efficiency and reduce operational costs at UMKM Rinjanni Ciamis.

Abstract

This study aims to design a business model for Washer Car Wash in Tebet using the Product-Service System (PSS) approach as a strategy to enhance competitiveness in the vehicle wash service industry. A descriptive qualitative method was employed through observations, questionnaires, and interviews with the business representative. The PSS analysis was conducted to identify the current business model (existing), desired development (desire), and the most feasible recommendation (eligible). The findings indicate that the current model operates as a pure service business, with development potential toward product related service and pay per service unit. Based on the quadrant analysis, product pooling emerges as the most feasible development, implemented through the concept of a “One Stop Care Hub” that integrates multiple automotive services within a single location. This recommendation is expected to enhance customer value, operational efficiency, and the competitive positioning of Washer Car Wash.
