Abstract

Digital era demands all thing could be done in computerized system to solve problems in easier way. So do with verification and identification system that continues to evolve with technology development. One of the implementations of it is face recognition. Human faces were taken as verification and identification system because they have unique characteristic and identity between one and others. Face recognition implementation on computerized system could be done with eigenface algorithm. Eigenface is one of face recognition’s algorithm based on Principal Component Analysis. Based on the best threshold value prospecting, it’s obtained for 2400, that value obtained for 100% of face recognition success rate. The image that can’t be detected and recognized as someone’s face is an image that has image distance error greater than predetermined threshold value and due to significant difference in light intensity of training images and test image.Keywords: Eigenface, Image, Euclidean Distance, and Face Recognition

Abstract

The using of alternative energy as a power source is intended to solve the problems of electricity supply which has not reached the entire region of Central Sulawesi province, especially in Sigi regency. The utilizing of hybrid system of solar and wind power is a solution that can be considered as a source of electrical energy which the solar cell is used as the primary source, whereas wind turbines can be used as a complementary source when solar irradiance cannot meet load requirements. This research aims to design and build alternative sources of electrical energy which is based on hybrid system of solar and wind power by taking into account the geographical factors of place where the system is built.Keywords: hybridsystem of solar and wind power, solar cells, wind turbine.

Abstract

The development of control systems has now reached a level that better facilitate the work of man. Most of control systems have been used in industrial companies.However, there is another thing that also have important rule in making easier the human's assignment which is in form of manual control, namely the simulation display system, installed on a device that is used to control theequipment using display on PC (Personal Computer) without facing them directly.This system has started to be implemented and applied by some modern industries. One example of the use of simulation display system is the construction of the simulation of reverse osmosis systems on PLTU (steam power plant) in order to facilitate the operator to run the simulation test. The problem statement created in this research was how to design the simulation display of reverse osmosis systems using the programming language of Macromedia flash 8, Delphi,ISIS Proteus, and Micro Pascal and then communicate it with the simulation of microcontroller based reverse osmosis systems. The result of this research is the simulation display of reverse osmosis systems which iscreated manually and automatically. The systemis communicated with the simulation of microcontroller based reverse osmosis systems where there are five motors and three tanks.The motors will drain the water of each tanks through the filtration process. Later on, the pure water as the final result of the filtration process will be used for steam cycle process in the boiler. Keywords: Simulation display, Reverse Osmosis Systems, Macromedia flash 8, Delphi, ISIS Proteus. I. P
