Abstract:
The objective of this research was to reduce the proportion defect of aluminium foil strip, which are the most defects in tablet packaging strips due to incomplete sealing. The research was started by analyzing the causes of problems and related factors with a Cause and Effect Diagram and screening the factors by using the Cause and Effect Matrix scores and Analysis of defects and their Effects Failure mode and Effect Analysis by assessing the Risk Priority Number (RPN). It was found that the factors that resulted in incomplete sealing were temperature of sealing roller, speed of sealing roller, the tension of the print foil and the unprint foil. Using one factor at a time to test adjusting the tension of the foil on both sides equally resulted in less defect than adjusting the different tension levels. Therefore, only 3 factors were filtered, namely Sealing Roller temperature, speed of sealing roller, foil tension on both sides, and applied the general full factorial design experimental. To find the appropriate level of factors. From the experiment it was found that the optimum factor level was the temperature of the sealing roller equal to 130 0C, the speed of sealing roller was 14 rpm, the tension of the foil on both sides was level 7. When the factor level applied in the process was applied in tablet packing process, the average daily proportion of Defect reduced from 4.82% to only 1.38%.
