Abstract

The production of batik experiences an increasing demand every year. This requires an improvement in both productivity and flexibility in the batik production process. Layout becomes one of the crucial factors in enhancing productivity and flexibility since it influences the material handling process. Well-designed facility layouts can improve the smoothness of material transfer operations, reducing material handling distances and, consequently, lowering material handling costs. This research aims to provide the best alternative layout. Several stages are carried out in this research, including classification to group cells based on part family, using the Rank Order Clustering (ROC) and Similarity Coefficient (SC) methods. Next, the calculation of the shortest transfer distance is conducted using Distance-Based Score Calculation, along with the use of Particle Swarm Optimization (PSO) to determine the department sequence. The research results show that the same cell grouping is achieved using both ROC and SC methods, with Cell 1 {Spray paint, proxy paint, Compressor, Welding, Grinding}, and Cell 2 {CNC Milling and CNC Turning}. Based on the distance traveled problem, it is found that the travel distance on the existing intuitive layout and the new suggested flow is 315.75 and 292.96, respectively. Therefore, by implementing group technology to implement cell manufacturing, it can provide a more effective and efficient material flow and Work In Process (WIP). Meanwhile, the results PSO yields a total minimum travel distance of 7,701.851 meters and a total material handling cost of Rp. 220 per meter, resulting in a total material handling cost of Rp 1,694,407.

Abstract

This study explores optimizing Yogyakarta's chocolate production system facility layout to enhance laboratory-scale production to mass production at the UGM Field Research Center laboratory. The laboratory layout was optimized based on expert assessments and the ALDEP algorithm and compared with the current layout using distance-based objective values. Both layouts were compared to highlight the importance of qualitative aspects in determining workstation positions, in addition to quantitative aspects. The distance-based analysis results indicate that the ALDEP layout outperforms the current layout, and the layout was designed with expert assessments, showing the highest efficiency and lowest material handling costs, with an estimated improvement of 23% over the current layout. Although the proposed expert-assessed layout performed worse, it met stakeholder requirements such as safety and ease of observation. Therefore, future research must consider other aspects beyond costs in evaluation metrics to determine the best layout.
