PT. XYZ merupakan salah satu perusahaan yang bergerak di bidang sektorproduksi otomotif yang memproduksi kendaraan roda dua (sepeda motor),dan ingin terus melakukan inovasi serta memberikan kualitas pelayanan yangterbaik kepada pelanggannya walaupun PT. XYZ memimpin pangsa pasarkendaraan roda dua (sepeda motor). Untuk mengetahui tingkat kepuasanpelanggan pada seksi workshop, dilakukan analisis dengan menggunakanmetode servqual dan six sigma. Pada metode servqual atribut pernyataanpelayanan dibagi menjadi 5 dimensi kualitas yaitu tangible, reliability,responsiveness, assurance dan empathy. Sedangkan metode six sigma merupakansuatu metode pengendalian kualitas dengan tahapan define, measure, analyze,improve dan control. Hasil analisis servqual menunjukkan bahwa tingkatkepentingan pelanggan melebihi tingkat kepuasan, hal tersebut dilihat darinilai gap yang negatif. Gap terbesar adalah dimensi reliability sebesar -0.36 dandari hasil importance-performance analysis menunjukkan atribut no 8, 11, 14, 16,22, 25 dan 35 sebagai prioritas utama perbaikan. Selanjutnya dari hasil analisissix sigma berdasarkan dimensi dan atribut yaitu rata-rata pada level 2.26sigma. Usulan yang diberikan berdasarkan 5W+1H yaitu SOP JO, memberikantraining dan membuat jadwal pengantaran part.

PT. B is one of the manufacturing company engaged in the field of plastic packaging. One of the products produced by companies that bottle Yamalube to customer PT. Yamaha. Based on daily reports of production companies, found that the percentage of disability have an average of 14% per month in which the company standard is 5% per month. It is necessary for Six Sigma to improve the quality of the bottles with the steps Define-Measure-Analyse-Improve-Control (DMAIC). In the define phase diagram created SIPOC and Quality Plan Yamalube bottle production process. In the measure phase created Sigma level. At this stage the known value of 0.16 DPU, DPMO of 250, 000 and the results showed that the conversion DPMO sigma level Yamalube bottle production process is equal to 2.17. In the analyze phase using a decision tree is known that bottles attributes that influence the decision of rejection is the position of the label, the number of labels, colours and perforated. By using FMEA method is known that improvements will be prioritized on the label of disability are not two sides to the root cause of the wear rubber. Repairs carried out by making the inspection SOP rubber, checksheet and proposals in the form of anti-static vacuum tool.

Business intelligence systems participate to deliveran accurate and useful information to decision makers in marketing division of bakeries manufacture. The purpose of this study was to design business intelligence model to analyze the marketing product, design the data mining model, measure and analyze the marketing process of the product they sell. The methodology of this research wasto analyze system requirements, design unified modeling language, make process extract, transform, and load, designdata warehouse, and data mining that integrated with the on line analytical process cube webbased. The business intelligence model produced was a marketing data mining model and on line analytical process cube. The result from on line analytical process cube was the data warehouse of transaction in R Bakery. In designing the data mining, Kmeans clustering method was used. The results from data mining k-means clustering were there were 83% cluster 1 and 17% cluster 2. Cluster 1 wasthecategorize for low leftover breads and cluster 2 was the categorize for high leftover breads. The model cube recency, frequency, and monetary and customer lifetime value resulted ranked out of the most amount of sales in R Bakery.

An electric cable is a medium that is in the form of a conductor and insulator to deliver electric current from the area of origin to the destination. The quality of a cable is very much determined by the medium of transmission, the delivery material can be copper or aluminum. PT XYZ Tbk is one of the companies engaged in the electrical cable that produces bare conductors. One type of product produced by PT XYZ Tbk is medium voltage cable. Medium voltage cable is a type of cable that can deliver electricity to 35 kV. But among various types of medium voltage cables, NFA2XSY-T products have the highest fail rate among other types of medium voltage cable, which makes the frequency of rework and repair of these products higher. Based on historical data for three months, from June to August 2018, it is 21%, while the company’s target is 1%. Therefore, in this study a quality improvement was carried out to minimize the level of defects with the six sigma method with the Define Measure Analyze step. Improve Control. In the Define stage, it is done by identifying the type of defect, step Measure evaluates the stability of the process and identifies the quality costs associated with defects that occur, in the Analize stage, by analyzing the causes of the dominant defect, in the Improve phase, improvements are made by making standard operating procedures, then at the control stage, it is attempted to compare between DPMO and Sigma Level before and after implementation. Based on data processing obtained DPMO of 77,585, and Sigma Level of 2.9, with total quality costs of Rp. 21,260,413 / day, after implementation DPMO was obtained at 55,556 and Sigma level of 3.9 with a total cost of Rp. 14,049,757 / day
