Abstract
In the Building section of a tire manufacturing company, the machine consists of three main parts, namely the ply up drum, building drum, and belt tread drum, where one of the process stages involves transferring material from the ply up drum to the building drum using a vacuum system equipped with flat suction pads. This system is designed to lift and transfer tire components without causing deformation. However, in actual operational practice, the vacuum system frequently encounters issues related to suction pad damage, particularly on the rubber wall edges, which are prone to wear and tearing due to repeated use and uneven material surface conditions. This damage results in reduced suction performance, causing the material to be lifted improperly and potentially disrupting the production process. Based on operational data from March to June 2025, the total machine breakdown time caused by suction pad damage reached 4,694 minutes, significantly affecting work efficiency and production line productivity. Therefore, this study was conducted using a parametric approach by modifying the suction pad design from a flat configuration to a folded suction pad. The analysis was carried out numerically using SolidWorks Flow Simulation to evaluate the fluid flow characteristics and the performance of the vacuum system. The results indicate that after the modification to the folded suction pad design, the head loss value decreased significantly by 79%, demonstrating a substantial reduction in head loss within the system. Furthermore, comparison of the goal plot graphs shows that the folded suction pad produces more stable flow characteristics, indicated by faster convergence of velocity, total pressure, and fluid temperature, as well as smaller fluctuations. This improvement in flow stability directly enhances system reliability, which is clearly reflected in the reduction of total breakdown time from 4,694 minutes to 2,380 minutes, or approximately 49%. Thus, the folded suction pad modification has proven to be effective in improving the efficiency and productivity of the tire manufacturing process. Keyword : Machine Building, Vacuum, suction pad, breakdown, Solidwork flow Simulation Pada bagian mesin Building di perusahaan manufaktur ban, terdiri dari tiga bagian utama, yaitu ply up drum, building drum, dan belt tread drum, di mana salah satu tahapan adalah pemindahan material dari ply up drum menuju building drum menggunakan sistem vakum dengan bantalan hisap berbentuk datar. Sistem ini dirancang untuk mengangkat dan memindahkan material penyusun ban tanpa menimbulkan perubahan bentuk. Namun, dalam praktik operasional di lapangan, sistem vakum sering mengalami kendala berupa kerusakan bantalan hisap, khususnya pada bagian dinding karet yang mudah mengalami keausan dan robekan akibat penggunaan berulang serta kondisi permukaan material yang tidak selalu rata. Kerusakan tersebut menyebabkan penurunan daya hisap sehingga material tidak terangkat secara optimal dan berpotensi mengganggu proses produksi. Berdasarkan data operasional periode Maret hingga Juni 2025, total waktu breakdown akibat kerusakan bantalan hisap tercatat mencapai 4.694 menit, yang berdampak signifikan terhadap efisiensi kerja dan produktivitas lini produksi ban. Oleh karena itu, penelitian ini dilakukan dengan menggunakan metode parameter melalui modifikasi desain bantalan hisap dari bentuk datar menjadi bantalan hisap berlipat. Analisis dilakukan secara numerik menggunakan perangkat lunak SolidWorks Flow Simulation untuk mengevaluasi karakteristik aliran fluida dan kinerja sistem vakum. Hasil analisis menunjukkan bahwa setelah dilakukan modifikasi dengan menggunakan bantalan hisap berlipat, nilai head loss mengalami penurunan yang sangat signifikan, yaitu sebesar 79%, yang menunjukkan berkurangnya headloss dalam sistem. Selain itu, hasil perbandingan grafik goal plot menunjukkan bahwa bantalan hisap berlipat menghasilkan karakteristik aliran yang lebih stabil, ditandai dengan konvergensi kecepatan, tekanan total, dan temperatur fluida yang lebih cepat serta fluktuasi yang lebih kecil. Peningkatan kestabilan aliran tersebut berdampak langsung pada meningkatnya keandalan sistem, yang secara nyata ditunjukkan oleh penurunan total waktu breakdown dari 4.694 menit menjadi 2.380 menit, atau berkurang sekitar 49%, sehingga modifikasi bantalan hisap berlipat terbukti efektif dalam meningkatkan efisiensi dan produktivitas proses produksi ban.
