Abstract

The palm companies typically consist of the oil palm plantations and the palm oil mills. Besidesproduced from their own plantations, they also buy the palm oils, CPO, and the kernel (palm kernel) fromthe farmers or other processing plants. The productions of the oil palm plantations of the farmers sold tothe collectors, and the collectors sell the palm oils to a processing plant. According to the collectors, whosell the palm olis to the factory, the price is cheap though the palm oil is in a good quality. They think tocultivate oil palm themselves, but the price of oil palm processing machines cannot be reached by them.This study will make the palm fruit crushing machine capacity of 50 kg/h, which is expected to be used bythe oil palm farmers in order to increase the sales value of the plantation. The method adopted to solvethis problem is starting with the preparation of the list of requirements necessary products, manufactureand concept selection, component design, manufacturing of image detail engineering, manufacture andassembly and test tool functions. The trial results of the palm fruit crushing machine with capacity of 50kg/h can be chopping the palm fruit with a specific gravity of 0.8245kg/liter.

Abstract

Minimum surface roughness results are a desirable objective in the CNC NLX 2500 Y process, a precise adjustment of CNC NLX 2500 Y process parameters should be obtained in order to obtain minimal roughness of the workpiece surface. The research has been conducted to determine the contribution ofCNC NLX Y 2500 process parameters to reduce the variation of the work surface roughness response simultaneously. And the determination of the exact setting of CNC NLX Y 2500 process parameters in order to obtain minimal roughness of the workpiece surfaces. parameters of machining process are variedspindle rotation, cutting speed, the dept of cut. The experimental design is based on the Taguchi method and is an orthogonal matrix L8 (2³). The optimization method used is Taguchi. The experiment was conducted randomly with replication 2 times to overcome the disturbance factor that occurred during machining process. The results showed that to reduce the variation of the response simultaneously, the the dept of cut has the largest contribution, that is 82.6%, the spindle speed has a contribution percentage of 61.9%, the cut rate has a contribution percentage of 9.2%. To obtain a surface roughness of the workpiece is minimal, the spindle rotation is set at 2866 rpm, the cutting speed is set to 0.40 mm / rotation, the dept of cut is set to 1 mm.
