PT. ZXY merupakan perusahaan yang bergerak dalam produksi alas kaki yang tidak terlepas dari permasalahan efisiensi dan efektivitas pada mesin (peralatan) yang diakibatkan oleh six big losses. Masalah yang terjadi pada mesin laser di departemen cutting kurang optimalnya proses pemotongan komponen alas kaki, oleh karena itu perlu dilakukan langkah-langkah untuk mencegah atau mengatasi masalah tersebut dengan bertujuan untuk mengetahui tingkat efektifitas mesin laser. Tujuan penelitian ini adalah untuk menghitung efektifitas melalui metode Overall Equipment Effectivenes (OEE) yang kemudian dilanjutkan dengan pengukuran OEE pada six big losses untuk mengetahui besarnya efisiensi yang hilang pada ke enam faktor six big losses, selanjutnya diperoleh faktor yang paling tinggi pada six big losses di mesin laser yaitu Equipment Failure Losses sebesar 53,97%. Dengan diagram pareto dan analisa sebab akibat dapat dianalisis masalah sebenarnya yang menjadi penyebab utama rendahnya efektifitas yang mengakibatkan rendahnya produktivitas mesin laser adalah punching head di sebabkan faktor manusia, mesin dan material.Hasil kesimpulan yang dapat diambil pada penelitian mesin laser ini setelah dilakukan perbaikan adalah dengan meningkatkan availability mesin laser dari rata-rata 96,2% menjadi 96,4% berdampak pada meningkatnya OEE dari 91,9% menjadi 92,1%.Kondisi ini sangat ideal (≥85%). Sehingga yang mempengaruhi nilai OEE dan menjadi prioritas utama dengan kontribusi terbesar terjadi pada Equipment Failure Losses dapat diatasi.

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.

Every company, especially manufacturing companies are required to make efficiency in each line to increase productivity in order to compete with other companies. With the increasing demand for new products from customers, or usually called a New Project, companies are challenged to utilize the work area as much as possible with the existence of new production lines to meet the customer's demand. To do that, the company should immediately make improvements on all lines so that free space will be obtained which will be used for new projects. To reduce the Lead Time on the line in the production department with the expectation to get an optimal working area which creating space to be used for a New Project. Using the Value Stream Mapping method as a first step to mapping the entire process from upstream to downstream to identify Lead Time and lead to waste in each process. High waste occurs in the inventory lead time. Non-value added activities are mostly found in the inventory part after platting in receiving and finished good parts. It also found in the information flow of the finished good parts. While developing the future state map, it decreased the total lead time by about 5% so that it creating a workspace for the new projects.

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.
