ABSTRAK / ABSTRACT

PT Supernova Flexible Packaging merupakan perusahaan yang bergerak di bidang industri kemasan fleksibel. Salah satu proses penting dalam kegiatan produksinya adalah proses rewinding, yaitu proses penggulungan ulang material untuk menghasilkan gulungan yang rapi dan sesuai spesifikasi. Permasalahan yang ditemukan pada mesin rewinder adalah ketidakstabilan tegangan material (web tension) yang menyebabkan terjadinya kerutan pada material dan menurunkan kualitas hasil gulungan. Kondisi tersebut terjadi karena sistem pengaturan tegangan masih dilakukan secara manual sehingga tidak mampu mengkompensasi perubahan diameter gulungan selama proses rewinding berlangsung. Tugas akhir ini bertujuan untuk mengembangkan sistem kontrol tegangan material berbasis dancer pada mesin rewinder. Sistem yang dirancang terdiri dari dancer roll, aktuator hidrolik, potensiometer, inverter (Variable Frequency Drive), dan motor AC sebagai penggerak utama. Potensiometer digunakan untuk mendeteksi perubahan posisi lengan dancer yang merepresentasikan kondisi tegangan material. Sinyal dari potensiometer kemudian digunakan sebagai umpan balik bagi inverter untuk mengatur kecepatan putaran motor secara otomatis sehingga tegangan material dapat dijaga tetap stabil selama proses rewinding. Metode yang digunakan dalam penelitian ini meliputi identifikasi masalah, perancangan mekanis dan elektrikal, perakitan sistem, serta pengujian kinerja alat. Hasil pengujian menunjukkan bahwa sistem yang dikembangkan mampu melakukan koreksi kecepatan motor secara otomatis berdasarkan perubahan posisi dancer. Sistem juga berhasil meningkatkan kestabilan tegangan material dan menghasilkan gulungan yang lebih rapat dibandingkan kondisi sebelumnya. Namun, pada beberapa kondisi operasi masih ditemukan hasil gulungan yang kurang rapi sehingga diperlukan pengembangan lebih lanjut untuk mengoptimalkan performa sistem.

PT Supernova Flexible Packaging is a company engaged in the flexible packaging industry. One of the important processes in its production activities is the rewinding process, which involves rewinding material to produce neat rolls that meet quality specifications. The main problem identified in the rewinder machine was the instability of material tension (web tension), which caused wrinkles in the material and reduced the quality of the final roll. This condition occurred because the tension control process was still performed manually and could not compensate for changes in roll diameter during the rewinding process. This final project aims to develop a dancer-based material tension control system for a rewinder machine. The designed system consists of a dancer roll, hydraulic actuator, potentiometer, inverter (Variable Frequency Drive), and AC motor as the main driving unit. The potentiometer is used to detect changes in the dancer arm position, which represent the material tension condition. The signal generated by the potentiometer is used as feedback for the inverter to automatically regulate the motor speed, thereby maintaining stable material tension throughout the rewinding process. The methodology used in this project includes problem identification, mechanical and electrical system design, system assembly, and performance testing. The test results show that the developed system is capable of automatically adjusting motor speed based on changes in the dancer position. The system also improves material tension stability and produces tighter rolls compared to the previous condition. However, under certain operating conditions, the roll quality is still not completely uniform, indicating that further development is required to optimize system performance.
