One of the efforts company did continuously to compete was to reduce waste or anything that is not adding value to products such as waiting activity that cause unbalance of workload between workstations on a production path. This condition resulted in idle work station, accumulation of intermediate goods, and low work station utility. Companies finds an unbalance workload. This work station are apparently have to wait in a given time after workstations does behind it finished. For that reason, this study aims to balance the workload between workstations and increase the company production capacity. This research uses simulation approach by modelling the initial production with software promodel and evaluate performance the the initial production with an indicator current content, output, and average time in operation. The performance of the initial production line model was the smoothness index of 2007.5, the current content of 10 units, the output of 34 units, and the average time in operation of 35.19 minutes. The alternative model of the selected production trajectory is due to excel in four track performance factors is lowest current content (1 unit), highest output (48 units), lowest smoothness index (461,8) and highest production capacity (9,12 unit/hour).

This paper describes the application of 5S method in welding workshop and to highlight the significant contribution of 5S implementation to organizational progress both in terms of quality, productivity, work safety, and worker moral values. 5S is a work culture includes Seiri, Seiton, Seiso, Seiketsu, and Shitsuke. 5S is used to improve the quality of employees in handling their work activities. Welding workshop at small and medium scale (UKM) usually has a limited work area. Storage of irregular and unclear equipment and materials relates to increase search activity The search activity allows for delay. The key to successful implementation of 5S is the organizational commitment and worker discipline in handling the 5S. The application of 5S in welding workshop requires a storage device in the form of a rack equipment by naming information or information items saved in it. With the implementation of 5s and the procurement of storage rack able to minimize the search activity of 18.75% and the use of space 11.20%.
