This book consists of three research paper on application of technology in agriculture. It shows the engineering and mechanization concept that flow from laboratory to real application as need in agriculture sector. The testing was performed under laboratory control environment and dummy target point also was established to collect the actual data. To avoid the repeatedly process of training the image data and inefficient of capturing the image value, the colorspace value namely Hue is used as conducted in research paper number three. This study introduced the image based measurement for modeling the oil palm fresh fruit bunches (FFB) maturity prediction which enables the determination of the correct time for harvesting. The images were analysed for optical properties of Hue, using the analysis software that was developed at our research laboratory. The model is used to develop an equation for the software to enable the oil palm planters to determine the time of harvesting the matured oil palm fruit bunches in oil palm plantation.
