Abstract

AC Induction motors are sized for maximum load and are operated at a constant full speed, because they are supplied with power from AC lined at a fixed-sinusoidal voltage and fixed frequency. However, load of motor does not always same at many conditions but the input voltage and power of motor is fixed. Of course, it will influence the efficiency of the motor. One method to improve efficiency of the motor is varying the voltage as loaded its and called Motor Controlled. Motor Controlled is AC Drive that using SCR (Silicon Controlled Rectifier) as the output voltage controller by controlling the firing angle. By employing SCR Motor Controller that adjust the voltage of the motor offers advantageous to improve efficiency of motor and potential for significant energy savings.

Abstract

Optimization problem is the demanding problem for optimum solutions. The optimum (best) solution is asolution with minimum values, or maximum among a set of possible alternative solutions. In electricaldistribution network, problem of demanding achievement of optimum condition of system operationalperformance is essential. One of the factors necessary to consider in the designing of the primary electricaldistribution network is cost. Cost is closely related to length of cable used. It highlights the importance ofcalculating the minimum length of cable required in a network. The cable should be not only with as minimalas possible in length, but also regulated for better arrangement.Actually, in regulating the cable installation, longer path is more frequently selected. One of the ways ofachieving optimization condition is to use algorithm to determine a minimum spanning tree of the primaryelectrical distribution network system. In this study, the algorithm used is Prim’s algorithm.The research was conducted by designing a graph model of primary electrical distribution network inappropriate with the data obtained. Based on the graph, each was weighted for distance or length of networkcable by using the ArcView GIS 3.3. The data were then calculated and simulated by using computer to gaina minimum spanning tree of the primary electrical distribution network using the Prim’s algorithm

Abstract

The robots were the result of technology development which used to help human being, both in industrial orbeyond the industrial. In the beginning, the robots were such automatic machine which the system stillfeature as mechanic automatic with movement which controlled by simple control system. With thedevelopment of microcomputer, control system in the robot being developed by use the computer where themovement control and their sensor handled by the computer. It make the robot more skilled to handle anykind of jobs. In this study, the authors designed a type of arm robot. The planning of control system of armrobot using computer as data processor with interface PPI-8255 and parallel port (LPT1). Theimplementation of this study were one robot which made from iron frame by the prior driver power that weresix DC motors which use transmission system with gear wheel characteristic, and as the movement/positionsensor used encoder plates which will read by optocoupler. The system planning include generally mechanicsystem planning and hardware system planning

Abstract

This study examines in depth about the software requirements to build a public information service system. Inprinciple, this research aims is to develop a plan needs public information service system that can assist andaccelerate the process of public service and reduce errors so that the information will result in services that can beaccounted for. This research is expected to contribute to the academic world is to add insight and knowledgeabout software engineering and information systems of public service.Software public information service system is designed with an interface easy to understand Indonesianlanguage, web application, multiple-login, can be integrated with computer networks, and built with PHPscript programming language, database used is MySQL, as well as web server used is AppServ 2.2

Abstract

This study aims to establish a management information system web-based office stationery which is expected to help accelerate the process of reporting the use of stationery, and reducing the error information that willgenerate reports that can be accounted for.Based on the test results can be proved that the management information system web-based office stationery that is built to run well, it is characterized by the existing menus to work properly, the data entered into the database properly stored, and application update, insert, and select the database has been connected to the well too.
