Abstract

PT. XYZ merupakan salah satu perusahaan manufaktur yang bergerak di bidang industri sepatu. Produk sepatu yang diproduksi oleh PT. XYZ memiliki model sepatu PDH, PDL dan Casual. Ketiga model sepatu terdiri dari terdiri dari dua bagian utama yaitu bagian upper yang merupakan bagian atas sepatu dan bagian bottom merupakan bagian bawah sepatu dan model-model sepatu tersebut melewati proses produksi yang sama sehingga jika salah satu model sepatu mengalami keterlambatan maka model yang lain akan berdampak dan mengalami keterlambatan juga yang disebabkan oleh keterlambatan pencapaian target produksi upper dan bottom sepatu. Keterlambatan pencapaian target produksi tersebut disebabkan tidak seimbangnya waktu kerja setiap stasiun kerja pada lintasan perakitan departemen assembling. Pada penelitian ini dilakukan penyeimbangan lintasan perakitan menggunakan metode RPW-MVM dan perancangan simulasi dengan menggunakan aplikasi Promodel. Setelah dilakukan penyeimbangan lintasan perakitan diperoleh hasil, penurunan jumlah stasiun kerja menjadi 13 stasiun kerja, peningkatan line efficiency bottleneck situation menjadi 88,28%, balancing efficiency meningkat menjadi 91,76% dan pertambahan output rata – rata 117 pasang sepatu.

Abstract

This research began with the company's losses due to numerous product defects. The dominant defects in body puckering originated from the body press finishing process, which is a finishing process using an automatic press machine. In the pressing process, there are several influential parameters, namely temperature settings, time, and pressure. In addition, the type of fabric to be pressed also has an effect. Currently, the company does not have a reference for the press machine settings, so workers in carrying out the pressing process only rely on intuition. Therefore, the purpose of this research is to determine the settings for the body press finishing process using an automatic press machine that are appropriate based on temperature settings, vacuum time, and pressure in the body press finishing process using the Taguchi experiment method to help reduce the number of body puckering defects. From observations and interviews, it was concluded that the control factors that can be controlled that affect the occurrence of defects in jacket products are the temperature factor of 125°C and 130°C, the vacuum time factor of 15 seconds and 20 seconds, and the pressure of 25Psi and 15Psi. The experiment was conducted three times, namely the actual condition experiment, the proposed experiment, and the confirmation experiment. Each experiment was conducted with 24 replicas and 600 products. The results of data processing obtained the best settings, namely a temperature factor setting of 125°C, a vacuum time setting of 15 seconds and a pressure setting of 25 Psi with a defect percentage of 5.89% to 1.67% per day.
