Proceeding of the Thirteen Annual Conference on Industrial Engineering and Operations Management (IEOM), Manila, Philippines, March 7-9, 2023 © IEOM Society International Bulk Warehouse Layout Design Analysis Using the Dedicated Storage Method (Case Study: PT Krakatau Jasa Logistic) Helshy Azzahra Nur El Islami Logistics Engineering Pertamina University Jakarta, Indonesia 102419036@student.universitaspertamina.ac.id Resista Vikaliana Lecturer in Logistics Engineering Faculty of Industrial Technology Universitas Pertamina mailto:resista.vikaliana@universitaspertamina.ac.id Abstract The warehouse is a place to store goods in the form of raw materials, work-in-process goods and finished goods and a place that provides information about the status and condition of goods stored in the warehouse so that information can be easily accessed by interested people. This study aims to identify and analyze PT Krakatau Jasa Logistics’ warehouse layout problems, provide cargo storage layout suggestions to maximize capacity using the dedicated storage method, and determine the warehouse layout that produces the largest warehouse utility value. A comparison of the current warehouse layout with the dedicated storage method was carried out to choose a warehouse layout by maximizing the free in the warehouse based on the greatest utilization. The results of the study show that the proposed layout has greater utility compared to the current layout, namely 81% and 19% for forklifts and trucks, where the proposed storage layout only has a little free space or has maximized cargo placement, but in the current warehouse, there is a warehouse utility that is equal to 36% where in the storage layout there is still a lot of empty space in the warehouse.

Introduction The warehouse is a place to store goods in the form of raw materials, work in process goods and finished goods and a place that provides information about the status and condition of goods stored in the warehouse so that information can be easily accessed by interested people (Apple 1990, Francis, & White 1992). According to Heizer and Render (2009). The layout is a crucial decision in determining long-term operating efficiency. The layout has many strategic implications for determining a company's competitiveness in terms of capacity, maximizing the use of space in the warehouse, processes, flexibility, minimizing costs, quality of the work environment, customer contact, and corporate image. A practical layout helps a company to achieve a strategy that facilitates differentiation, low costs, or fast response. A layout strategy aims to create an economical layout that meets the competitive needs of the business. A good warehouse layout is by arranging the facilities in the warehouse so that workers can operate it more efficiently and speed up service. Workers no longer waste time looking for goods because they have been placed according to their characteristics. A good layout scheme will improve overall operating efficiency (Zhenyuan et al. 2011). Technology is growing rapidly, resulting in many advances, especially in the design of developments using engineering drawing software. With increasingly sophisticated technology, it can help speed up the completion of a 1145
