Abstract

The domestic fruits demand has increased during last ten years and is predicted that it will continoustly increase in the future. Indonesian fresh fruit export has also increased with a little fluctuation in the last five years. Meanwhile there are some constrains in the developing Indonesian fresh fruit export which ore low in quality homogeneity, inconsistent or discontinuity in supply. Ihe objective of this research was to evaluate the external qualities of pineapple fruit such as skin color, shape, and size at different stage of maturity and type of cultivation using image processing method. The results showed that the method can be used to determine the maturity of pineapple fruits accurately from their properties of skin color. This research found that there was a strong relationship between maturity and red color index (RCI) of pineapple fruit skin. The relationship equations were RCIclone= 0.026 T + 0.351 (R2 = 0.9456) and RCIratoon = 0.0347 T + 0.3182 T (R2 = O.9208) for clone and ratoon pineapple fruits, respectively. The method was also able to determine the size of fruit (diameter and volume of pineapple fruit) conclusively. The correlation equations between the image parameters and the measured unit are: Dukur = 0.7679 Dcitra - 21.181 (R2 = 0.8885) for ratoon pineapple fruits and Dukur = 0.5166Dcitra + 16.118 (R2 = 0.9861) for clone pineapple fruit. Whilst the prediction equations of fruit volume from projected area of the fruit are V = 4x10-6.Acitra - 0.0003 cm2 (R2 = 0.9917) for clone pineapple fruit and V = 4x10-6.Acitra - 0.0004 cm2 (R2 = 0.9939) for ratoon pineapple fruit.
