Comprehensive Study

Purpose – The purpose of this paper is to present the current status of a quality management practice in Serbia, in terms of the development and application of integrated managements systems (IMS), and research and implementation of Six Sigma and the related techniques. Design/methodology/approach – Two main aspects of total quality management (TQM) have been considered: institutional (organisational or strategic) aspect that corresponds to standardised management systems and their integration, and technical (quality engineering) aspect whose main contributor is Six Sigma. The findings of a comprehensive study on IMS implementation in Serbia have been presented, based on the results of a questionnaire that was sent to 54 organisations during 2013. Also, the significant technical improvements and tangible benefits of a recently conducted Six Sigma project were shown, including the application of the advanced quality engineering techniques within DMAIC method. Findings – Good QM practice in Serbia is improving, both in terms of the organisational (IMS) and technical (Six Sigma) aspect, that server as a good basis for the adoption of TQM in manufacturing companies from various sectors. It could be anticipated that these results will facilitate the adoption of an overall TQM culture in Serbia and leverage its future sustainability. Originality/value – This paper offers key insights into IMS and Six Sigma implementation in Serbia. This could encourage manufacturing organisations in developing countries to adopt IMS and Six Sigma, in order to boost the overall TQM culture and gain a competitive advantage.

Abstrak. Dunia industri yang semakin berkembang akan mengakibatkan banyaknya persaingan. Perus-ahaan yang dapat bersaing adalah perusahaan yang dapat menjaga  kualitas produknya dengan baik sehingga dapat memenuhi kepuasan konsumen. Maka dari itu diperlukan pengendalian kualitas. Penelitian ini difokuskan pada penurunan cacat pada produk batu bata merah di CV. Ghatan Fatahillah dengan metode Six Sigma-DMAIC (Define, Measure, Analyze, Improve, dan Control). Dari hasil penelitian didapatkan DPMO sebesar 36.212 dengan nilai sigma 3,29. Jenis cacat yang paling sering terjadi pada batu bata merah yaitu pecah/patah yaitu sebesar 4.327 atau 59,81% dari total keseluruhan produk yang cacat.  Hasil dari tahap analyze dengan fishbone diagram, ditetapkan penyebab dari pecah/cacat, yaitu: pekerja kurang paham standar kualitas, tidak adanya pemeriksaan produk, pekerja kurang paham prosedur kerja, kinerja mesin tidak stabil, pekerja kurang teliti,  jumlah penggilingan tidak menentu, dan komposisi batu bata tidak menentu. Maka perlu dilakukan usulan perbaikan agar dapat mengurangi jumlah produk yang cacat pada batu bata merah. Kata kunci: DMAIC, DPMO, Pengendalian Kualitas, Six Sigma Abstract. The growing industrial world will result in a lot of competition. Companies that can compete are companies that can maintain the quality of their products well so that they can meet customer satisfaction. Therefore, quality control is needed. This research is focused on reducing defects in red brick products at CV. Ghatan Fatahillah with the Six Sigma-DMAIC method (Define, Measure, Analyze, Improve, and Control). From the research results obtained DPMO of 36,212 with a sigma value of 3.29. The type of defect that most often occurs in red bricks is broken / broken, which is 4,327 or 59.81% of the total defective products. The results of the Analyze stage with the fishbone diagram showed that the causes of breakage / defects were determined, namely: workers do not understand quality standards, lack of product inspection, workers do not understand work procedures, unstable machine performance, workers are not careful, the number of mills is erratic, and composition erratic bricks. So it is necessary to make improvement proposals in order to reduce the number of defective products in red bricks. Keywords: DMAIC, DPMO, Quality Control, Six Sigma

ABSTRAKPenelitian ini dilakukan pada salah satu produsen spare part otomotif PT. XYZ memiliki permasalahan dan menjadi perhatian serius pada bagian pengelasan adanya produk cacat yang dapat menurunkan nilai dan kualitas produk sehingga banyak produk yang ditolak oleh konsumen karena tidak sesuai dengan standar, dimana banyak terdapat kotoran las (Spatter) yang menmpel pada Joint Exhaust produk Half Outer Comp merupakan bagian komponen dari knalpot sehingga mengurangi produktifitas produksi pada bagian inspeksi akhir, permasalahan di atas dianggap perlu dilakukan penelitian untuk mencari penyebab hal tersebut. Beberapa langkah dilakukan guna memperbaiki cacat yang ada yaitu langkah awal dilakukan observasi dan wawancara ke bagian produksi, metode yang digunakan untuk pengolahan data hasil observasi menggunakan metode DMAIC (Define, Measure, Analisys, Improve, Control), kemudian dilakukan optimalisasi dan modifikasi Jig Welding dengan mendesain ulang menggunakan perangkat software Solidwork versi 2018, kemudian mengubah posisi Jig sebelumnya vertikal menjadi horizontal agar supaya pada saat pengelasan Spatter tidak langsung jatuh ke Joint Exhaust dan memberikan penahan tambahan pada Jig guna mengurangi jumlah Spatter menempel pada Half Outer Comp. Pada penelitian ini diperoleh hasil dimana jumlah Spatter yang menempel pada Joint Exhaust sangat berkurang dan memperoleh hasil produk yang lebih baik sehingga meningkatkan produktivitas pada bagian inspeksi akhir sebelumnya 58,33% menjadi sebesar 83.33%.  Kata Kunci :  Optimalisasi, Spatter, DMAIC, Desain, Solidwork 2018 ABSTRACTThis research was conducted at one of the automotive spare part manufacturers PT. XYZ has a problem and is a serious concern on the welding part of the presence of defective products that can reduce the value and quality of the product so that many products are rejected by consumers because it does not comply with standards, where there is a lot of welding dirt (Spatter) which attaches to the Joint Exhaust Half Outer Comp product is a component of the muffler so as to reduce production productivity at the final inspection, the above problems are considered necessary to do research to find the cause of it. Several steps were taken to correct existing defects, namely the initial steps carried out observation and interviews to the production department, the method used for processing the observation data using the DMAIC method (Define, Measure, Analysis, Improve, Control), then optimization and modification of Jig Welding with redesign using the 2018 Solidwork software tool, then changing the position of the previous vertical jig to horizontal so that when welding Spatter does not directly fall into the Joint Exhaust and provide additional support to the Jig to reduce the number of Spatter attached to the Half Outer Comp. In this study the results obtained where the number of Spatter attached to the Joint Exhaust is greatly reduced and obtain better product results thereby increasing productivity in the previous final inspection section of 58.33% to 83.33%. Keywords : Optimization, Spatter, DMAIC, Design, Solidwork 2018

Purpose The purpose of this paper is to apply the Six Sigma DMAIC methodology in order to reduce the rejections experienced in the manufacturing of the doors belonging to a telecommunication cabinet. Design/methodology/approach The process involved joining of sheet metal and hinge using welding operations with the help of a fixture. The methodology used is the structured DMAIC method in order to identify the root cause for the rejections and solve it. Findings The paper provides insights about the identification of the root cause for the defects and the solution to overcome it, and also the benefits that were obtained as a result of the application of the solution. Research limitations/implications This methodology has been applied to the variation observed in the dimensions of a particular component to be welded with a main part. This approach can be used to find such dimensional variations. Practical implications This study has been successfully carried out in a medium-scale industry which has total quality management in practice. Originality/value Six Sigma DMAIC was necessary for the identification and reduction of the defects which arose in the sheet metal and welding operations, and had to be resolved in order to increase the bottom-line.
