Abstract

This research employs the Economic Order Quantity (EOQ) method to optimize procurement practices for welding wire in boiler manufacturing. With a focus on reducing storage and inventory costs, the study aims to determine the optimal order quantity. Findings reveal that the calculated total inventory cost using the EOQ method significantly reduces compared to the company's existing policy. The optimal order quantity of 407 boxes, purchased four times per year, coupled with a safety stock of 181 boxes, ensures efficient procurement management. This research underscores the importance of implementing quantitative analysis techniques in procurement strategies to enhance cost-effectiveness and operational efficiency in manufacturing industries. Highlight : The study determines the optimal order quantity of K71T welding wire, reducing storage and inventory costs. The Economic Order Quantity (EOQ) method is applied, resulting in a total inventory cost of Rp. 89,060,000,- compared to the company policy of Rp. 290,840,000,-. The findings can be used as a reference for other manufacturing companies facing similar procurement challenges to optimize their inventory management and reduce costs. Keywords: welding wire, optimal order quantity, inventory management, procurement challenges, manufacturing companies

Abstract

UD Coba Dirasa adalah perusahaan yang memproduksi beberapa jenis mie mentah sebagai bahan baku untuk membuat mie pangsit, mie ayam dan mie goreng. Kendala yang dihadapi oleh perusahaan tersebut adalah penentuan harga jual produk, hal ini disebabkan alokasi biaya tidak tercatat dengan baik. Penelitian ini bertujuan untuk menentukan harga jual produk yang kompetitif dengan tetap mempertahankan kualitas produk. Penelitian ini merupakan penelitian deskriptif dengan menggunakan metode cost plus pricing, yaitu suatu metode yang digunakan untuk menentukan harga jual dengan menjumlah biaya total dan margin. Hasil penelitian ini adalah perusahaan dapat mencapai persentase keuntungan mie basah (putih) sebesar 16%, mie basah (kuning) sebesar 18%, mie gepeng sebesar 25% dan kulit pangsit sebesar 83%.

Abstract

General Background: Warehouse layout plays a critical role in supporting material handling efficiency and operational performance in industrial systems. Specific Background: The studied company experienced excessive travel distance and disorganized item placement, leading to inefficiencies in retrieval and storage activities. Knowledge Gap: The existing warehouse arrangement had not applied a systematic storage classification based on item movement frequency, resulting in suboptimal space utilization and material flow. Aims: This study aims to redesign the warehouse layout using the Class Based Storage method to minimize travel distance and improve storage organization. Results: The analysis classified items into movement-based categories and proposed a new layout configuration that reduced total travel distance compared to the initial condition. The redesigned layout also improved accessibility for high-frequency items. Novelty: The study demonstrates the practical application of Class Based Storage in a specific industrial warehouse context supported by quantitative travel distance analysis. Implications: The findings provide a structured reference for warehouse management strategies focused on layout planning, storage classification, and operational efficiency improvement within industrial engineering practices. Keywords: Warehouse Layout, Class Based Storage, Travel Distance, Material Handling, Industrial Engineering Key Findings Highlights Storage classification based on movement frequency reorganized item placement systematically. Proposed configuration lowered total material transfer path compared to the initial arrangement. High-rotation products were positioned closer to access points to streamline retrieval activities.
