Malang Indah Genteng Rajawali is a manufacture company producing some kind of roof tile, and paving which is located in the town of Malang, East Java. In the current conditions of the production process at the company indicated to make defect arising in the production of roof tile with type Royal. This is detected by an increase in the number of defect that do not meet the quality standard of both the company and consumers. Defects that occur in the production process of the current royal tile types such errors on the long process of soaking and arrangement of tiles on a soaking tub due to a lack of clear working procedures as well as the fault of the operator. The purpose of this thesis is to reduce the number of defects and obtain cost savings for companies using Six Sigma. The stages of this study is the first to define the stage, explained the object of study selection, identify the type of defect, and the flowchart of the production process. While on stage measure, determine the product attributes that are critical to the quality of CTQ (Critical To Quality), measuring the level of defects in the form of DPMO and sigma level that will be the foundation of early performance. Furthermore, the stage of analyzing the types of defects analyze the main pedestal in improving the quality problem and what factors are the cause of defects by using a fishbone diagram. And improve on the stage, using failure mode and effect analysis (FMEA) to assist in determining the corrective action plan that can be implemented to reduce defect levels. The last stage is the control, which document the repairs and make control charts to track and monitor the production process. The survey results revealed that the most dominant defect occurred in the company was broken at the edges, and the hook is not perfect. The corrective actions taken to improve stages, namely the procedural flow of clear and structured activities in the socialization process of soaking through the standard operating procedure (SOP) to workers and provide directions arrangement of tiles on a soaking tub. So the mechanism of production procedures run smoothly and causes defects that occur can be minimized.
