6. METHOD
A. Measurement parameter
Rice grading is needed to be evaluated from many difference parameters in order to get an accurate result of grading. The parameters are taken from the features of the rice. Every rices will have difference features maybe in term of but length, colour and shape. But the same group of rice will have almost the same range in every feature. From that difference we will classified them in several group namely A,B and C that indicated A as the good quality of rice, followed by group B and the worse class is group C. The first parameter to classify the rice is length. The longer the rice shows that the rice get enough nutrient while growing and have no defect. The ideal length for the rice is 8mm to 10mm which suppose be the range for group A. Group B range of length is 8mm to 4mm and below than that is range for group C. The second parameter used is colour. When we talk about rice, the common colour of rice that will come in mind is always white. There is also rice in other colour but our main concern for this research is the white rice. The whiter the rice shows the better the quality. The third parameter used is the shape. The ideal shape of the robot is shown as the diagram below. If the shape more than 80 percent likes the ideal shape then the rice is categorized as group A. The range for group B is between 79 percent until 50 percent while the rest is group C
