PT Burangkeng Maju Tehnik (BMT) is a company engaged in steel fabrication. This company falls under the job-order industry, where the production process takes place after receiving orders from customers. Currently, PT BMT employs a fixed position layout, in which the production process is carried out in a single location until completion. The components of the products need to be transported to the workshop at a considerable distance. This leads to a high material handling cost of Rp24,480,000 per month. Furthermore, the current machine layout is irregular, there is unused land that is not optimally utilized for production space. Furthermore, this existing layout has 9 units per month for its capacity and cannot reach the demand as many as 13 units per month. It happened because the lack of assembly area in the existing layout. The objective of this research is to create a layout design that minimizes relocation costs and optimized land utilization. The layout design will be accomplished by determining the appropriate layout type for PT BMT's industry and utilizing the Systematic Layout Planning (SLP) method. This method requires input data such as product information, quantity, routing, and time. Evaluation for the layouts using the analytical hierarchy process (AHP) to select the best layout. The research yields four layout design proposals. The proposed layouts result in material handling costs of Rp21,267,000, Rp22,301,790, Rp19,960,890, and Rp22,017,040 per month for layouts one, two, three, and four, respectively. AHP is then utilized to determine the best layout based on criteria such as flexibility, material handling effectiveness, flow effectiveness, space utilization, material handling cost, and rearrangement cost. The AHP results indicate that layout 1 is the best, providing a material handling cost saving of Rp3,213,000 and improved space utilization. Layout 1 also gives additional room for assembly process.
