Determining process variation via statistical process control

Author:Abdul Talib Bon, Anizah Mohd Yunus, Berhanuddin Mohd Salleh and Asri Selamat

Abstract:
This research is carried out to study the used of SPC tools towards identifying the variation in quality finished product at Bio-organic fertilizer company. The objectives of this research are to analyze and monitor quality of finished product using Xbar R chart and identify the relationship between variables using scatter diagram. Data was obtained from Quality Department through finished product of 5.5.5PE from January 2008 until December 2008. This finished product can be measure according to pH, moisture, and crash. SPSS version 11.5 software has been used to analyze and interpret the data into control chart and scatter diagram. The unstructured interview with respective workers was done in order to support the data analysis. The finding revealed that the SPC tools can determine process variation in finished product through systematical analysis with more accurately. Since All Cosmos has no specific tool to analyze the data, it is suitable for them to implement this tool.
