Abstract - The ‘kerem’ production process is the earliest process of the entire process in iron casting. The brake itself is a mandatory thing in an iron foundry company because it functions as a limiter of the inner diameter of an iron casting product or more simply as a hole in iron casting products. With the analysis carried out using seven tools, it is expected to be able to obtain actual data to improve the quality of brake production, look for factors that affect brake quality, control the number of rejects, countermeasures, repairs, and standardization. The biggest problems with defects in the production of brakes are porous, broken, cracked and not full sand. From the aspect of 4M + 1E, the Man factor is the dominant cause of brake defects. Meanwhile, the number of rejects outside the 2.5% AQL limit was 6 times, namely on 8 July 2021 as many as 16 pcs (AQL 2.5% was at 10 pcs). Then on July 17, 2021 as many as 15 pcs (2.5% AQL at 13 pcs) on July 18 2021 as many as 30 pcs (2.5% AQL at 2 pcs) on July 20 2021 as many as 25 pcs (AQL 2.5% was at 12.63) on 27 July 2021 as many as 20 pcs (AQL 2.5% was at 19 pcs) and finally on August 5, 2021 as many as 30 pcs (AQL 2.5% was at 12.6 pcs).

The quality of remanufacturing products, which is always restricting the development of remanufacturing industry, is one of sixty-four-dollar questions. By detecting the cores, process control in remanufacturing production and certificating remanufacturing products, quality control of remanufacturing products is studied. Because of cores different in original states, remanufacturing is in low-volume on the whole. Based on Bayesian posterior analysis, the paper improves the control chart and uses the previous data to monitor the production process. Finally, some advances are given to remanufacturing product certification.

The aim of this study was to demonstrate the application of Statistics Quality Control in fierce industries. By observing Batik production process at PT XYZ as a case in this work, we applied Six Sigma Method to analyze defective product and their cause while also measure overall quality goodness. Six Sigma is a method to improve a process and reduce defects in productions into 3.4 defects per million productions. We use handprint batik productions at PT XYZ as a case in this study. The method is involving Define, Measure and Analyze (DMA) phases. By using Six Sigma, it was obtained that the quality of handprint batik are quite good with sigma of 3.105 and defect rate of 54.269 million production (DPMO). There are four defect causes of handprint batik namely: ripped fabric, shallowness, perforation, and mispattern which contribute 41,7%, 35,8%, 15%, 7,5% respectively from overall defects. The main cause of defects is the carelessness of workers in production process. Therefore we need to reduce the carelessness to  improve production quality.

AbstractThe publication analyses the way of managing and improving the quality of the production process of aluminum pistons for internal combustion engines. The aim of the article is to propose a method of analysis of the effectiveness of individual control methods used in the process of controlling the aluminium piston. Thanks to the location of a control point with the highest share of product non-compliance detection in the production process, it is possible to reduce quality control points by less effective points, which will contribute to lower costs or shorten the time of production processes. In view of the increasing demands on the efficiency of the checkpoints for components in internal combustion engines, the issue is important and topical.

Quality control at all stages of the polygraphic process will allow to establish a feedback between technological processes of printing. The validity of the selected criteria, technological effectiveness and objectivity of the quality assessment methods will allow to organise technically accurate modelling of the processes as well as to promptly interfere with the production process if necessary. The tendency of the development of technologies and control tools as well as computer expansion are the reasons why the objectivity and impartiality of the assessment become the main criteria for the choice of method for quality assessment of the polygrafic product. Methodological purpose of the quality control is to make the polygrafic process technologically driven and stable, and the quality of the received print - more predictable.

ABSTRAKBayam Jepang adalah komoditas unggulan yang diproduksi oleh PO. Sayur Organik Merbabu dengan tingkat penjualan tertinggi mencapai 1018 kg/bulan. Salah satu faktor yang perlu diperhatikan dalam proses produksi adalah kualitas produk, karena akan berdampak terhadap kepuasan konsumen. Akan tetapi terdapat kendala dalam proses produksi, yaitu sifat tanaman yang sangat rentan rusak dan patah jika tidak diperlakukan secara tepat. Sehingga perlu dilakukan analisis kualitas terhadap Bayam Jepang untuk menekan tingkat kerusakan. Tujuan penelitian ini adalah mengetahui jenis cacat dan faktor-faktor yang mempengaruhi kualitas Bayam Jepang.  Penelitian ini dilakukan pada 16 Januari sampai 20 Februari 2020 dengan metode deskripstif kualitatif dan menggunakan alat pengendalian mutu seperti lembar periksa, histogram, peta kendali, pareto dan fishbone. Jumlah informan yang digunakan terdiri dari pemilik usaha, tenaga kerja, petani mitra dan distributor. Setelah dilakukan penelitian ditemukan lima jenis cacat yaitu daun cacat, batang patah, daun kuning, tanaman kerdil dan busuk batang atau daun. Persentase cacat yang paling tinggi adalah daun cacat. Faktor-faktor yang mempengaruhi kualitas Bayam Jepang adalah faktor manusia, metode, dan lingkungan yang didukung dengan pembuatan diagram fishbone.ABSTRACTJapanese spinach is a superior commodity produced by PO. Sayur Organik Merbabu with the highest level of sales reach 1018 kg / month. One factor that needs to be considered in production process is product quality, because it will have an impact on customer satisfaction. However, there are obstacles in the production process, namely the nature of plants that are very susceptible to damage and broken if not treated properly. So it is necessary to conduct a quality analysis of Japanese spinach on an ongoing basis to reduce the level of damage. The purpose of this study is to determine the types of defects and factors that affect the quality of Japanese spinach. This research was conducted on January 16 to February 20, 2020 with qualitative descriptive methods and using quality control tools such as check sheets, histograms, control maps, pareto and fishbone. The number of informants used consisted of business owners, workers, partner farmers and distributors. After doing the research, five types of defects were found, namely defective leaves, broken stems, yellow leaves, dwarf plants and stems or leaf rot, with the highest percentage of defects being defective leaves. While the factors that influence the quality of Japanese spinach are found, namely human factors, methods, and the environment supported by making fishbone diagrams.

The increasing number of bag factories throughout Indonesia that have well-known brands and every manufacturer is required to provide products of good quality. Poor product quality will cause consumers to move to other similar products. So in the production of bags, the thing that must be considered by the company is the quality of its products. In this study the authors aim to analyze quality control in a production process and identify several factors that cause disability in the product, PT. MAG is a bag company that is demanded to control the quality of the production process. This study uses a six sigma analysis tool consisting of five steps, namely using the DMAIC method (Define, Measure, Analyze, Improve, and Control). Based on the results of the study there are three types of disabilities in the production process, including cutting, zippers and broken bag straps with an average sigma value of 2.48 with a DPMO value of 20256.92. Factors affecting the production process are human, machine, environment, equipment, raw materials, and methods. In this case the company can use the Six Sigma method because it is still in the medium category.
