To ensure the quality of the product, the quality systems and techniques such as quality checking and Andon
system were proposed. Quality checking will be available at the end of each process or cell. One of the quality
tools that can be implemented is check sheet. Andon system can be used as a signal assistant in cell 1 because it
involves machines and operators. The signal when machine was down can be triggered by pushing a button or a
cord or even by the equipments itself.
