ABSTRAK/ABSTRACT
Tugas Akhir ini berfokus pada pengembangan sistem otomasi pada mesin strip packing Chentai di PT Hexpharm Jaya untuk mengatasi risiko tinggi human error selama penyortiran manual produk yang mengandung sambungan foil. Saat ini, mesin belum dilengkapi sistem deteksi dan penolakan otomatis, sehingga operator harus mengandalkan inspeksi visual yang rentan terhadap kesalahan akibat kelelahan dan sifat pekerjaan yang monoton. Tujuan dari proyek ini adalah merancang dan mengimplementasikan sistem auto-reject otomatis yang diintegrasikan dengan struktur mesin yang ada (retrofitting) untuk memastikan hasil produksi zero-defect sesuai standar Good Manufacturing Practice (GMP).
Sistem otomasi ini menggunakan sensor kontras SICK KTX Prime untuk mendeteksi lakban merah pada sambungan foil, yang diintegrasikan dengan PLC Siemens S7-1500 untuk pemrosesan logika secara real-time. Mekanisme aktuator pneumatik yang dikendalikan oleh solenoid valve digunakan untuk membuang produk cacat secara otomatis. Sistem ini juga menerapkan logika shift register di dalam program PLC untuk menyinkronkan sinyal deteksi dengan kecepatan mekanis mesin, memastikan waktu penolakan yang presisi. Overhaul pada panel utama juga dilakukan untuk meningkatkan keandalan sistem dan kemudahan perawatan. Hasil pengujian menunjukkan bahwa sistem berhasil mendeteksi dan membuang produk cacat secara otomatis, secara signifikan mengurangi beban kerja operator serta meningkatkan produktivitas dan jaminan kualitas mesin.

This Final Project focuses on the development of an automation system for the Chentai strip packing machine at PT Hexpharm Jaya to address the high risk of human error during the manual sorting of products containing foil splices. Currently, the machine lacks an automatic detection and rejection system, forcing operators to rely on visual inspection, which is prone to error due to fatigue and the monotonous nature of the work. The objective of this project is to design and implement an automatic “auto-reject” system integrated with the existing machine structure (retrofitting) to ensure a zero-defect output in accordance with Good Manufacturing Practice (GMP) standards.
The automation system utilizes a SICK KTX Prime contrast sensor to detect the red tape used for foil splicing, integrated with a Siemens S7-1500 PLC for real-time logic processing. A pneumatic actuator mechanism controlled by a solenoid valve is employed to reject defective products automatically. The system also incorporates a shift register logic within the PLC program to synchronize the detection signal with the machine’s mechanical speed, ensuring precise rejection timing. Overhaul of the electrical panel was also conducted to improve system reliability and maintenance. The results demonstrate that the system successfully detects and rejects defective products, significantly reducing the burden on operators and improving the machine’s overall productivity and quality assurance.
