Analisis Stabilitas dan Kapabilitas Proses Spinning Benang Katun dengan Metode Six Sigma (Studi Kasus PT. Primissima)
Abstract: As a textile company
which produces grey, PT. Primissima surely needs high quality yarn which is
also produced in its factory as its main basic material. Decline in yarn
quality that significantly happened on May until August 2004 causes negative
effects to the company, especially in customer satisfaction. Analysis of
process stability and capability is should be done to prove and explain the
problem, particularly on the existing spinning III process. Analysis using Six
Sigma method begins with identifying customer needs, then mapping customer
needs into the critical to quality characteristics (CTQ), determining CTQ
priority level based on customer importance rating and customer satisfaction
rating, and last, measuring sigma value, process stability and process
capability of the CTQ top priority level. The result that focused on unevenness
yarn CTQ shows, with sigma value of 4.07 sigma, process condition isn’t stable
and capable enough to meet the company’s specification target. From the process
analysis is also obtained information that many factors like environment,
machine, tool, process, material, employee, and measurement system are supposed
causing the problem. Improvement and control suggestions are also given here.
