Abstract:This study aims to analyze the level of service quality and prioritize improvements. The method that used in this study is service quality (SERVQUAL) combined with fuzzy concepts to find out the gap between expectations and consumer perceptions through five dimensions namely tangible, reliability, responsiveness, assurance, and empathy. Fuzzy concepts are used to present uncertainties over respondents' assessment of subjective questionnaires. To determine the priority of improvement, used the Customer Value Index Potential Gains (IPGCV) method. Based on processing data results by using fuzzy-servqual method, it is known that the Tangible dimension has a gap of -0.13, the Reliability dimension has a gap of -0.13, the Responsive dimension has a gap of -0.14, the dimension of Assurance has a gap of -0.12, Empathy dimension has a gap of -0.11. The negative value on fuzzy-servqual assessment can be interpreted that the overall service has not met customer expectations. Achievement of the quality level is equal to 0.8606 which is indicates the quality of services still need improvement because the level of service quality is less than 1 (Q

Abstract:The brick making process has two very critical characteristics / Critical To Quality (CTQ) , namely compressive strength and water absorption. For the quality characteristics of the compressive strength the greater the value, the better (Higher The Better). As for the absorption of water the quality characteristics are getting smaller, the better (Smaller The Better). The quality of the brick used as building material must have good quality that can maintain the strength of existing buildings. The quality in question is the compressive strength and absorbency of water produced must be in accordance with the requirements of SNI (Indonesian National Standard). The WS companies produce concrete blocks which have not good quality. The bricks are brittle. The method used in this study is the Taguchi method. Optimal Level Factor setting is Factor A (duration of stirring), Factor B (Pressure), Factor C (Water), Factor D (Drying) and Factor E (Composition of Sand and Lime). Where the optimal factor setting level factor that is most influential and dominant in compressive strength and water absorption is factor E (composition of sand and lime). For compressive strength factor E (sand and lime composition) level 2, 1: 0.25 and for absorption factor E (composition of sand and lime) level 1, 1: 0.5. and to confirm the results of this experimental design study, a percentage of Quality Loss Function of compressive strength and water absorption was obtained after the optimal level setting had a quality increase of 51.91% and a decrease in the Loss function of 78.5%.

Abstract:PT. Tainan Enterprises Indonesia branch of Cianjur produce various kinds of garment products. One of the most widely product is trousers. The product are still many defects. This is showed from the number of defective products during February 2015 until mid- March 2015 which reached 509 products unit of 10.138 trousers produced. Therefore, appropriate quality control is required to optimize the quality of trousers products. This research method uses Six Sigma approach with DMAIC cycle (Define, Measure, Analyze, Improvement, Control). Based on the results of the research is known the most dominant type of defect is oblique belt loop and skid jump defects. Factors causing of oblique belt loop defects are sourced from human factors (operator does not follow signs and operators are fatigue), engine factor (old machine age and engine setting less than perfect), material factor (needle material less reliable and materials need to be heating which is high), and the method factor (information on working methods is still lacking). While the factors causing of skid jump defects are sourced from human factors (operator is less careful in choosing to sewing needles and operators experience fatigue), machine factor (old machine age and no regular machine maintenance), material factor (needle less reliable sewing), and method factors (production supervision and quality control are still weak). Quality Increasing could be can increase the value of Six sigma from 3.82 to 4.27.
