RANCANG BANGUN PENGUPAS BIJI LADA MENGGUNAKAN SISTEM CRUSHER

Abstract

<em>Processing of post-harvest pepper includes threshing pepper from its stem, soaking and paring of pepper seeds. Paring of pepper seeds is still traditional. Pepper put into sacks and soaked for 10-14 days then trampled using human power. Using the traditional system takes a long time and the peel is not perfectly flaked and the energy required is huge. Therefore, it is necessary to design and manufacture the machine to replace the human power function, process and  time of paring. The tool will be made by using a crusher system where 2 pieces of rubber-coated disks are rubbing against each other and flooded with the goal of shifting the pepper's peel meet the rubber. The disc consists of one dish in permanent and another will rotate that is transmitted by the bevel gear and the source of energy is electric motor. The dimension of the dish is 400 mm in diameter, the dimensions of the hole to put pepper is 30 mm and rotating speed of dish 15 rpm. The pepper used in this research is freshly picked pepper without soaking. Variables measured by time and exfoliation results. The research was found that 89% of the pepper was flaked perfectly, 11% did not exfoliate perfectly, the machine capacity is 1 kg/hour.</em>
