As time goes by, quality becomes one of the most important things. Indicator good
products, resulting from the good quality control. The product result from packaging industry varies
so as to cause analysis and control processes quality becomes unequal and not maximal. In this case,
the reseacher using the Six Sigma method with DMAIC’s phase (De ine, Measure, Analyze, Improve,
Control). There are many tools that the reseacher used, like project charter, SIPOC’s diagram, Voice
of customer (VOC), control chart, Fault Tree Analysis (FTA), Failure Mode Effect Analysis (FMEA).
From the results project charter is obtained that is the problem regarding how to reduce customer
complaints against BT products 8251 (42%) to (15%). Then the results of the control chart (u-chart)
that reject of the product sent to customer has not been controlled. After that, the causes were
analyzed using Fault Tree Analysis (FTA). Improvements are recommended to reduce defects based
on RPN (Risk Priority Number) from Failure Mode Effect Analysis (FMEA). There are several
suggestions that are tried to be applied in the industry but it still cannot be seen being followed up.
