The Quality Of Brick Products In Brick Production Process Using Six-Sigma Method At A Brick Factory In Deli Serdang Regency

摘要

Increasingly tight competition in a business world drives companies to further develop ideas to obtain an effective and efficient way in order to achieve organizational goals and objectives that have been set. The same case lies with a Brick Factory in Deli Serdang regency, as one of the companies in plastic manufacturing industry. This paper aims to measure the level of quality of brick production process by using Six Sigma method. Six Sigma is a vision in improving quality to reach a target of up to 3.4 DPMO (Defect per Million Oppurtunity) through Six Sigma phases, namely: Define, Measure, Analyze, Improve, Control (DMAIC). At the measure phase, the results showed the defect of 23,239 DPMO that produces 3.44 sigma level, while the provision of six sigma is 3.4 DPMO or 3.6 sigma level. By using the six sigma meth od through a series of activities of Define, Measure, Analyze, Improve, Control (D MAI C), it is expected that solutions are provided to achieve the defects target particularly that of the most critical one.
