This study aims to measure the effectiveness of the Stretch Blow machine at PT. X by calculating the Overall Equipment Effectiveness (OEE) value. Stretch Blow Machine is one of the machines used in the manufacturing process of plastic bottles. These machines often suffer damage so that targets and product quality are often not achieved. The purpose of this study was to determine the most dominant factor of the Six Big Losses on the Stretch Blow Machine. The method used in this research is descriptive quantitative. Based on the results of data processing and analysis, it shows that the average value of Overall Equipment Effectiveness (OEE) for the period January 2017-December 2017 is 43.89%, while the Overall Equipment Effectiveness (OEE) World Class Value is> 85%. For that, it is necessary to do research using quality control tools, namely Pareto and fishbone diagrams. The results of the data analysis with the Pareto diagram found that the largest Idling Minor and Stoppage Losses is 39.28%. The causes of Idling Minor and Stoppage Losses based on the results of the fishbone diagram analysis are lack of machine operator skills, unavailable engine spare parts, machine maintenance schedules are not running and the quality of engine spare parts is not suitable. The improvement plan of the factors causing Idling Minor and Stoppage Loses using 5W + 1H have to be implemented so that the Overall Equipment Effectiveness (OEE) value of the Stretch Blow Machine could be increased.

Delivery performance is essential for a manufacturer to meet customer requirement. The only manufacturer with fast, accurate and on time delivery could survive in global competition as a sports shoe manufacturer with the labor-intensive production process, PT. XYZ faced a problem with massive work in process inventory that impacted low delivery performance. This research aims to support the shoe manufacturer company to reduce work in process inventory by applying Kanban System. The manufacturer company can decrease work in process in the production line and cut the lead time of production. Kanban System can be utilized from receiving material process, production process, until the packaging process. By implementing a kanban system correctly and consistently, the company can control material supply, production material usage, and customer order delivery inaccurate process. With controlled those items, the company could monitor and manage material and process from beginning to end of the process, even to monitor distribution to a customer. The result of analysis proves that by applying kanban system can achieve the specified daily production target without work in process inventory.

Untuk meningkatkan volume penjualan dan keuntungan, maka perusahaan perlu memantau kinerja perusahaan secara keseluruhan, bukan hanya berdasarkan tingkat profitabilitas namun juga berdasarkan tingkat produktivitas. Produktivitas merupakan perbandingan antara output yang dihasilkan dan input yang digunakan. Penelitian ini bertujuan untuk mengetahui berapa besar tingkat produktivitas yang telah dicapai oleh perusahaan dengan menentukan indeks produktivitas, indeks profitabilitas dan indeks perbaikan harga dengan menggunakan model pengukuran The American Productivity Center (APC). Indeks produktivitas total yang diperoleh pada periode 2017 yaitu 114,252% dengan  indeks produktivitas input tenaga kerja, material, energi dan modal masing-masing pada periode 2017 yaitu 116,166%, 113,168%, 120,808%, 115,523%. Indeks profitabilitas total yang diperoleh pada periode 2017 yaitu 110,766% dengan indeks profitabilitas input tenaga kerja, material, energi dan modal masing-masing pada periode 2017 yaitu 128,903%, 103,246%, 129,615%, 125,563%. Indeks perbaikan harga dari tahun 2016 ke tahun 2017 diperoleh indeks perbaikan harga tertinggi pada input tenaga kerja yaitu 1,110% dan indeks perbaikan harga terendah pada input material yaitu 0,912%, indeks perbaikan harga energi dan modal masing-masing yaitu 1,073% dan 1,087%. Besar kecilnya indeks perbaikan harga dipengaruhi oleh biaya input yang digunakan untuk menghasilkan sejumlah output.

Shoe industry development in the era of globalization is currently overgrowing. Therefore, every company should be able to compete strictly with other companies that produce the same products. Quality maintenance is having to be done by the company to survive in business competition. PT. ABC is a manufacturer of sports shoes. The company has a problem with bonding shoes not achieved company standard in the year 2017. This paper is focused on the improvement of bonding shoe quality by using a method of Quality Control Circle which applying quality control tools are like check sheet, Pareto diagram, fishbone diagram, and 5W + 1 H. Based on the research results obtained percentage improvements of quality bonding test of 21.15%. Cement stripping on the midsole is the most significant number of the bonding test failure in Laboratory that is as much as 26.33% or 218 prs from the total collapse of the overall bonding shoes. Based on the background, the purpose of this research is to find out the root causes of the failure of bonding test shoes. The limitations of this research are only improving processes in the department, which makes the bonding shoe quality does not achieve the company standard. After doing the analysis using the quality control tools and making the improvement process in the whole areas that the percentage of the bonding test cement stripping on midsole could be increased to 5.18%. Analysis of the results obtained by applying the method of Quality Control Circle is the improvement of the quality of the bonding shoe. So, the trust customers against the company may be obtained that would eventually increase the number of orders to the company.
