Abstract
In tire manufacturing companies in Indonesia, there is a tire production process consisting of Material, Building, Curing and Final Inspection. The curing process is the process of changing green tires into tires which takes place in a mold segment at temperature and pressure according to predetermined specifications. In the BOM 63.5 curing press machine there is a segment cylinder which functions to press the mold segment. The problem that often occurs in curing machines is that the segment cylinder breaks. This causes quite high machine downtime. The number of cylinder segment bolt holes influences the strength of the bolt connection. Therefore, it is necessary to redesign the segment cylinder mounting bolt holes so that the bolts can support the cylinder load. The method used is using Finite Element Analysis by simulating the loading on the bolts. The results of this redesign can reduce curing machine downtime problems and can increase company productivity. Based on the results of this research, it can be concluded that 6 bolts are safer than 4 bolts. The downtime problem of the cylinder segment after modification decreased by 94%. The previous 253,019 hours became 17,3 hours. Key Word : Curing machine, cylinder seat, bolt holes, downtime Pada perusahaan manufaktur ban yang ada di Indonesia, terdapat proses produksi ban terdiri dari Material, Building, Curing dan Final Inpection. Proses curing merupakan proses mengubah green tire menjadi tire yang berlangsung di dalam mold segment dengan dengan suhu dan tekanan sesuai spesifikasi yang telah ditentukan. Pada mesin curing press BOM 63.5 terdapat silinder segment yang berfungsi untuk menekan mold segment. Problem yang sering terjadi pada mesin curing yaitu silinder segment jebol. Hal ini menyebabkan terjadinya downtime mesin yang cukup tinggi. Jumlah lubang baut silinder segment berpengaruh terhadap kekuatan sambungan baut. Oleh karena itu diperlukan redesain lubang baut dudukan silinder segment agar baut dapat menahan beban silinder. Metode yang dilakukan yaitu menggunakan Finite Element Analysis dengan melakukan simulasi pembebanan pada baut. Hasil redesain ini dapat menurunkan downtime problem mesin curing dan dapat meningkatkan produktivitas perusahaan. Berdasarkan hasil penelitian ini, dapat disimpulkan bahwa baut berjumlah 6 lebih aman dibanding dengan baut berjumlah 4. Hasil downtime problem silinder segment setelah modifikasi mengalami penurunan sebesar 94%. Yang sebelumnya yaitu 253,019 jam menjadi 17,3 jam. Kata Kunci : Mesin curing, dudukan silinder, lubang baut, downtime
