A Company

PT. Z is a company engaged in the plastic bag industry. The company produces plastic bags, one of which is a type of ATP 12 x 24 that is often used as plastic wrapping meatballs, sugar and others. A company is certainly required to provide the best quality on its products. To meet the needs and expectations of consumers for the quality of products, the company must improve the quality of existing products. Six sigma is a quality tool that can be used to analyze and process data to maintain or improve the quality of a product based on the process. One of the shorts used in the six sigma method is Define, Measure, Analyze, Improve and Control ( DMAIC). This research focuses on the results of product defects produced for 5 months in 2019. Because of the process analyzed there is data of proportions that are out of control in july and november. So that the data is omitted so that the data can be controlled. The sigma production level of ATP 12 x 24 is currently at the level of 4 sigma so it is necessary to improve to reach the level of 6 sigma. Pareto diagrams and fishbone diagrams can be used as tools to analyze significant factors causing product defects. And it can be known that the causative factor that can be done repair is deflated.

The objective of this work was to study salt reduction in the processing and final product of Iberian dry-cured ham manufacturing. For this purpose, high-barrier plastic bags were used in the salting stage, with salt doses of 2.5 and 3.2% at 10 and 15 d. The following aspects were evaluated: the production and salt content of brine, the analytical determinations of the hams after the salting stage, the changes in the total mass of the hams during processing and the analytical and sensory assessment of the dry-cured product. The experiment results showed that the plastic bag salting minimized the production of brine by 61 and 63% and reduced the salt content in the final product without altering the physicochemical characteristics or the hygienic quality of the dry-cured ham. In the sensory analysis, the samples salted with 2.5% doses were preferred by consumers.

The article evaluated the control of Stencil in the subprocess of Printing of the SMD line of a company located in the Industrial Pole of Manaus (PIM), to provide subsidies to develop a computerized system. With computerization, the focus of employees will be directed to the activities of production and quality of manufactured products, also, the collection of process data, done in real-time, will allow managers to better monitor and take actions in the process. To this end, a case study, bibliographic research of articles, dissertations, and theses involving the theme, and documentary research (forms, records, etc.) with the sectors involved were used. The descriptive statistics method was applied, quality tools were used, aimed at identifying and solving problems such as PDCA, Pareto, Ishikawa Diagram, flow chart, and 5W2H. A study of the activities related to the control of the Stencil was carried out, of the documentation used in the process, as well as of the factors and causes related to the effective Stencil control. Among the results, 24 causes affect the performance of the Stencil control, concluding that the main failures were human, due to the prioritization of production goals by the employees, leaving the other activities in the background, which is why the 24 guidelines proposed for the computerization of this process become relevant, some of which are: defining means to identify each Stencil using a bar code or QR code; do not allow the use of the Stencil if one of the activities unfinished in the process; stop production when an activity is not performed; digitize the documents used in this process; create an automatic notification to those responsible, when an action is necessary, etc.

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.

Quality is a key to be able to compete in the industrial world [16. Quality control is needed to reduce the number of defective products produced by the company, thus reducing losses experienced by the company. The Bima Mandiri Rembang Pasuruan cigarette company is a company that produces cigarettes, one of which is INNO cigarettes. The number of defective products produced by the company so that the company must make an increase in quality by using a method to reduce the number of defects that occur.  The number of defective products causes the company to suffer losses. For that, we need a method that can reduce cigarette defective products which in turn can improve the quality of the company's production[12]. Six Sigma with the DMAIC stage (Define, Measure, Analyze, Improve, Control) is a method used in this research. Based on these steps, defects that often occur are less dense cigarettes as many as 289 sticks with a percentage of 25%, tearing on the cigarettes as many as 227 cigarettes with a percentage of 20% and peeling cigarettes as many as 208 sticks with a percentage of 18%. Factors that cause defects include humans, machines, methods and materials. After calculating using the Six Sigma method, before the improvement, the DPMO value is 113988.1 and the Sigma Level value is 2.722. After the improvements were made, the DPMO value decreased to 76488.1 and the Sigma Level was 2.94715. To achieve the six sigma target, the company is expected to be able to carry out improvements with a focus on the factors that cause product defects and always carry out regular control to reduce product defects. The corrective steps taken in the Bima Mandiri Rembang Pasuruan Regency cigarette company are human: regular training for machine operators and employees; methods: inspection of raw materials, blending machines and glue residue in the teat; engine: inspection of engine components; material: reprocessing less refined raw materials and using better quality glue.

O objetivo deste trabalho foi verificar a qualidade de mudas de Enterolobium contortisiliquum produzidas em sacos plásticos de 1.248 cm³, tubetes de 280 cm³ e tubetes de 180 cm³, e posteriormente avaliar a sobrevivência e o crescimento pós-plantio. Na fase de viveiro, todos os recipientes produziram mudas de qualidade, com destaque para as produzidas nos sacos plásticos. Na fase de campo, as plantas oriundas de saco plástico e de tubete 280 cm³ apresentaram 100% de sobrevivência, enquanto as de tubete de 180 cm³ apresentaram apenas 58%. Apesar de as mudas produzidas em sacos plásticos apresentarem maiores medidas na época de plantio, constatou-se que essa diferença tende a diminuir ou desaparecer com o tempo, pois as mudas produzidas nos tubetes apresentaram maior crescimento relativo. Para produção de mudas de Enterolobium contortisiliquum, podem-se utilizar sacos plásticos com capacidade 1.248 cm³ ou tubetes de 280 cm3.Palavras-chave: Tubetes; sacos plásticos; orelha-de-negro. AbstractSeedlings production and initial growth in fields of Enterolobium contortisiliquum produced in different containers. This research aims to verify the quality of Enterolobium contortisiliquum seedlings produced in plastic bags of 1.248 cm³, tubes of 280 cm³, and tubes of 180 cm³, as well as evaluate their survival and growth after planting. In nursery stage, all containers resulted in quality seedlings, especially those produced in plastic bags. In field phase, plants from plastic bag and tubes 280 cm³ had 100% survival, while to the ones from tube of 180 cm ³ survival was only 58%. Despite seedlings produced in plastic bags present greatest measures in planting season, such difference tends to disappear in time, because the seedlings grown in tubes had higher relative growth. We recommend plastic bags of 1.248 cm³ and tubes of 280 cm³.Keywords: Tubes; plastic bags; orelha-de-negro.

The purpose of this research is to know how big the role of ISO 9001:2000 to a company that has been applied using cost-based approach to six sigma quality. ISO 9001:2000 is a standard on quality management. With the implementation of ISO 9001:2000 is to determine its effect on fee levels of quality. Where quality costs are the costs accrued or incurred to prevent and improve the quality of which occur as a result of not reaching the specifications of products or services that have been set. The analytical tool used in Six Sigma approach is the number of defects each year in each production department so it can know which department has the largest number of product failure as compared with total production in which the department will be the object of research. Besides, the cost of the quality of the department which has the largest defects will be analyzed to determine the total effectiveness of the department. The results of this study is the successful application of ISO 9001:2000 at PT Honda Precision Parts Manufacturing measured using six sigma where sigma approach in the year 2004-2009 has increased. As for the cost of quality is itself an increase in the cost of prevention and appraisal costs. This shows an improvement in terms of quality has been going well. Based on the above information, it can be concluded that the increase in sigma and increased costs of prevention and appraisal costs are not separated from the role of ISO 9001:2000 which has been applied. It is evident that any improvements made as specified in ISO 9001:2000 concept will cause a rise in the cost of some components in the calculation of quality costs, but improvements are made will affect the production of goods falling NG or defect that ultimately reduce overall quality costs.
