Abstract

The trend of tofu consumption in West Sumatra, based on Badan Pusat Statistik (BPS), particularly in Padang City, increased from 2022 to 2024, as reflected in Tahu Sumedang CC. Currently, regular daily production reaches 29.120 units, but 2,98% of the 336 working hours in February 2025 were allocated to overtime. During the two-week observation period in the same month, 6,04% of demand experienced distribution delays due to difficulties in meeting high demand. Observations also revealed inefficiencies in production activities, such as 19,69% delay at workstation IV by the first worker while the second worker is preparing the tofu before they continue to complete the transferring to the pressing station together. This study aims to increase production capacity through work method improvements and workload balancing. Work method improvements are carried out by applying the principles of the motion economy, while the balancing is conducted using the workload balancing approach. The evaluation results are then followed by capacity planning to assess whether the proposed improvements are sufficient to meet future demand projections. Based on the work method improvement calculations, the delay time by the first worker while the second worker is preparing the tofu at workstation IV was successfully reduced to 2,25% allowing the remaining time to be used to assist other workstations. Workload balancing also succeeded in reducing 41,48 minutes/shift, equivalent to 1 hour and 22,96 minutes/day. In addition, the balancing process increased production capacity by 3.640 tofu units/day, or approximately 12,5% of the current production. This additional capacity is expected to meet future consumer demand without the need to purchase additional machines or hire more workers.
