This paper investigates the application of eight color models for automatic palm oil Fresh Fruit Bunch (FFB) ripeness classification with multi-class Support Vector Machine (SVM).  Ripeness classification is important during harvesting to ensure that they are harvested during the correct ripe stage for optimum oil production.  Since color is a significant indicator for agriculturists to determine the ripeness of FFB, it is critical to determine the right color model. Eight color models have been investigated namely, HSV, I1I2I3, LAB, XYZ, YCbCr, YIQ, YUV and RGB. Color moments were extracted from each of these color models for the classification of four stages of FFB ripeness that are unripe, under-ripe, ripe and over-ripe.  A database of five hundred images of palm oil FFB has been constructed and experiments showed that YCbCr and YUV outperform the other color models.

Method Analysis

Oil Palm fresh fruit bunch (FFB) transportation is a vital step in post harvest process. Transportation condition mayaffects the quantity and quality of FFB as a palm oil factory raw material. Due to many estate roads are not at idealcondition, this research was addressed to explore the relationship between road damage level and position of FFBin truck bin to transportation performance. Transportation performance indicator were leftover fruit, level of releasedfruitlets, fruits bruise index, and free fatty acid (FFA) content. The research divided into two stage. The first wason transportation performance in collection road. The second was FFB transportation from fruit collection point tofactory, which was treated on good, moderate, and bad road. Observation was done to the FFB at bottom, middleand upper layer of truck bin. The transportation performace indicators were analized by Anova, and continued byTukey method analysis if there were differentces among treatments. Result showed that level of road damage wassignificantly affect transportation performace indicator i.e level of leftover fruits, but it was not significantly affectlevel of released fruitlets, fruits bruise index, and FFA content. Meanwhile, FFB position in truck bin influenced levelof fruitlets releasing, and significantly influenced fruits bruise index.Keywords: Palm oil transportation, leftover fruits, released fruitlets, bruise index, oil Pal FFB ABSTRAKPengangkutan tandan buah segar (TBS) kelapa sawit merupakan satu tahap penting dalam proses pascapanen.

Cocoa bean (Theobrama cacao) is an essential raw material in the manufacture of chocolate, and their classification is crucial for the synthesis of good chocolate flavour. Cocoa beans appear to be very similar to one another when visualised. Hence, an electronic device named the electronic nose (E-Nose) is used to classify the odor of cocoa beans to give the best cocoa bean quality. E-nose is a set of an array of chemical sensors used to sense the gas vapours produced by the cocoa bean and the raw data collected was kept in Microsoft Excel, and the classification took place in Octave. They then underwent normalisation technique to increase classification accuracy, and their features were extracted using mean calculation. The features were classified using CBR, and the similarity value is obtained. The results show that CBR's classification accuracy, specificity and sensitivity are all 100%.
