Perancangan Proses Produksi Kursi Belajar Adjustable

Abstract

Production process design is a critical stage in product development to ensure time and cost efficiency. This study designs the production process of an adjustable study chair intended for elementary school students. The approach includes process modeling using an Operation Process Chart (OPC), cost estimation with the full costing method, and process flow simulation using Promodel. The OPC reveals 27 operation activities and 20 inspections required to assemble one unit. The total production time recorded is 1 hour and 34 minutes. The estimated production cost per unit is IDR 515,806, covering raw materials, labor, machinery, and overhead. Simulation results indicate workload imbalance at the assembly station, which may become a production bottleneck. These findings serve as a basis for improving work scheduling, resource allocation, and overall production efficiency
