Analisa Kinerja Mata Pisau Mesin Pengiris Kulit Kelapa Muda

Abstract

Young coconut is generally presented naturally with the cone shape above. This coconut formation process has been done manually in the home industry using a machete. This process has a high risk of work accidents. Coconut produced in this process has a shape that is less attractive, not uniform, and difficult to open. Therefore, it takes a young coconut skin slicer that can produce a better, uniform, and safe form to use. To design young coconut skin slicer, it is important to analyze the cutting mechanism of young coconut skin. The purpose of this study was to analyze the cutting mechanism of young coconut skin, build a mathematical model for estimating the specific style of cutting, and get the maximum cutting power of young coconut skin. Variations in sharpness angle, cutting angle, and blade side are optimized to produce the lowest cutting force. A mathematical model has been constructed to estimate the maximum cutting force for a one-sided blade sharpening and two sharpened edges with cutting angles 00, 150, and 300. From the results of the study concluded that the type of knife that produces the lowest cutting force is a two-sided blade sharpening with an angle sharpness of 100 and angle of cut 300. The lowest power for cutting perpendicular to young coconut skin is 0.12 kW which is produced using a sharpened two-sided knife with a sharpness angle of 100 and a cutting angle of 300. The maximum playback power needed to cut young coconut skin is 0,75 kW.
