Abstract

PT. Aneka Timber & Furniture merupakan perusahaan yang bergerak di bidang industri pengolahan kayu. Dalam proses produksinya, Sisa-sisa kayu hasil produksi tidak dibuang melainkan disatukan kembali dengan mesin finger joint. Pada finger joint terbagi menjadi 2 mesin yaitu mesin shaper wood dan juga mesin press. Pada mesin shaper wood terdapat 9 silinder pneumatik. 3 silinder pneumatik sebagai feeder, 4 silinder pneumatik sebagai clamp dan 2 silinder sebagai penarik/pendorong meja konveyor. Pada sistem pneumatik 9 silinder mesin shaper wood ini membutuhkan kapasitas standart sebesar 0,5026 m³/menit dengan tekanan absolut sebesar 901.325 Pa atau 9,013 bar. Total pressure drop yang dialami oleh 9 silinder pneumatik yaitu sebesar 0,12Bar. Untuk memenuhi tekanan tersebut terdapat 2 pilihan air receiver yaitu dengan kondisi air receiver diisi tetapi air receiver tidak me-supply udara ke sistem pneumatik sebesar 38 m³. Untuk air receiver dengan kondisi air receiver diisi tetapi air receiver juga me-supply udara membutuhkan volume air receiver sebesar 0,4m³ dengan kapasitas kompresor 0,55286 m³/menit . Untuk kompresor dengan kapasitas 0,55286 m³/menit membutuhan daya motor listrik sebesar 11,8kW dengan kompresor Shark H-250. Pada pemiilhan Directional
Control valve (DCV) direkomendasikan dengan nilai flow coefficient (Cv) sebesar 0,289 sehingga dipilih double solenoid DCV tipe VS4210-03 port 3/8” dengan brand SMC.

=====================================================================================================

PT. Aneka Timber & Furniture is a company engaged in the wood processing industry. In the production process, the remnants of wood produced are not discarded but are put back together with a finger joint machine. The finger joint is divided into 2 machines, namely a Wood Shaper machine and a press machine. The wood shaper machine has 9 pneumatic cylinders. 3 pneumatic cylinders as feeders, 4 pneumatic cylinders as clamps and 2 cylinders as pullers/pushers on the conveyor table. In the 9 cylinder pneumatic system this wood shaper machine requires a standard capacity of 0.5026 m³/min with an absolute pressure of 901.325 Pa or 9.013 bar. The total pressure drop experienced by 9 pneumatic cylinders is 0.12 Bar. To meet this pressure, there are 2 air receiver options, namely with the condition of the air receiver being filled but the air receiver not supplying air to the pneumatic system of 38 m³. For the air receiver with the air receiver condition being filled but the air receiver also supplying air, it requires a volume of 0,4 m³ of air receiver with a compressor capacity of 0.55286 m³/minute. To drive a compressor with a capacity of 0.55286 m³/min requires an electric motor of 11,8kW with Shark H-250 compressor. In the selection of the directional control valve (DCV), it is recommended with a flow coefficient (Cv) value 0,289. So that the DCV is double solenoid type VS4210-03 Port 3/8” is selected with the SMC brand
