Abstract

Development technology of computer programs caused to produce novelty from the development of these technologies. Besides to education, the development of technology can be utilized in working, even all. Digital image processing is a part the development of it. This research develop of identification system of red and white meranti by using color detection method. The program used in this research is a Matlab program. In this research, database made by 25 pieces red meranti and 25 pieces white meranti. Image of woods captured side by side using webcams. Then taking the values of primary colors RGB (red, green, blue) to be used as database. Identification system will test 5 times for every red and white meranti with different positions. Success rate of identification system red and white meranti using color detection method is 90.83%.

Abstract

During spring valve release process of the car cylinder head, workshops experiencing difficulties due to the released manually. The release is done by hitting the outside of the valve spring retainer which can cause damage to the valve spring retainer and also may reduce the stiffness the valve spring. It is designed tools for release spring valve on the cylinder head car. In this paper is conducted for the initial phase to design a tool, and then carried out the calculation of the force required to remove the workpiece spring valve. Tools will be made in accordance with the calculations have been done then proceed with testing tools. Once the tool has been tested, the evaluation and study of literature that will be used for the selection of materials. From the data calculation, the force required to depress the valve spring is 1942.4 N and material using the steel SC-42. Mechanism of action of the tool using a lever or a lever in order to facilitate suppression valve springs.
