Abstract

The objective of this research was to detect the quality of mangostaan fruit based on its calyx wholeness using image processing method. Sixty samples of fresh local mangostaan fruit was used for experiment. Samples were consisted of three categories: diameter >65 mm (A),55-65 mm (B), and <55 mm (C), Fruit properties parameters measured are weight, volume, and diameter. Parameters of image measured are area projection of fruit and calyx, and its radius. The result showed that the calibration equation of area projection was Au = 0,0029 Ap + 0,3106 (R2 = 0,99). For all categories, there is a closely relation between weight and volume of fruit with coefficient of determination about 0,53- 0,97. Area of projection can be used to determined volume of fruit, furthermore diameter of image can be well explained by diameter of object (R2 = 0,89). Area projection of calyx and fruit ratio can be used to classify the quality of fruit. The ratio values of each category are 0,479; 0,696; and 0,774 for A, B, and C category respectively.
