Abstract:
According to the process start on January 2008 to March 2008 was old document before
research. We found to defect in process to 951 pieces or 8.77 percents from production 10,848
pieces. Average per month was in production 3,616 pieces, defect 317 pieces and total 8.77
percent for defect. If we did not correct may be to loss in many products. Also we correct to the
applied QC seven tools for analysis to corrective action and result from analysis we bring to
correct in process on September 2008 to November 2008 for this research.
Result to this research by correct and improve in process on September 2008 to November
2008 found to defect in process to 1,079 pieces or 6.96 percents from production 15,510 pieces.
Average per month was in production 5,170 pieces, defect 360 pieces and total 6.96 percents.
Result from this research we used tools in analysis only 4 case had Check Sheets,
Histograms, Cause and Effect Diagram and Pareto Diagram. It was only for shown to average per
month for percent reduction of defect 8.77 percents to 6.96 percents. That is our objective for
need to reduce defect 1.50 percents from 8.77 percents.
