Abstract

T XYZ adalah perusahaan manufaktur ban yang berfokus pada peningkatan kualitas produk. Di Plant C, yang memproduksi Automobile Tube dan Bladder, proses extruding sering mengalami kendala pada tahap marking line. Pengadukan dan penyaringan cement dan solvent dilakukan secara manual, menyebabkan postur kerja tidak ergonomis dan berpotensi menyebabkan rework pada green stick tube. Dengan metode RULA, diidentifikasi risiko tinggi pada postur operator). Posisi badan membungkuk, jika dilakukan secara berulang tentu akan mengakibatkan musculoskeletal disorder apabila tidak dilakukan penanganan ataupun pencegahan. Untuk solusi, dirancang alat pengaduk cement marking menggunakan Motor Pneumatic Rotary yaitu air grinder yang di kontrol dengan sistem kontrol elektro pneumatik sehingga alat pengaduk akan bekerja secara otomatis mengaduk selama 15 menit dan mati secara otomatis selama 8 jam ketika push button on di tekan, hal tersebut akan terus berulang sampai push button off atau emergency switch di tekan. Jumlah total energi yang di habiskan oleh alat ini dalam satu hari yakni 1,54 Kwh..

Abstract

At PT XYZ, the Bias cutting process plays a crucial role in tire production, particularly in the handling ofTreatment rolls involving the Air Brake Roll Treatment system. Currently, pressure adjustment on the Bias cutting machine at the Let Off section is performed manually by operators, often leading to inaccuracies in pressure reduction. These inaccuracies result in uneven compression of the Treatment rolls, leading to increased scrap rates and reduced production efficiency. This study aims to modify the pressure system by replacing the manual method with an automated system using the IFM O1D100 Distance Sensor. This modification involves automatically adjusting pressure based on the distance of the Treatment roll, thereby reducing the risk of unwanted compression and enhancing the consistency of the Bias cutting process. The study results show that using an electro-pneumatic system controlled by the Distance Sensor allows for more precise pressure adjustment, contributing to reduced scrap rates and improved production efficiency.
