Implementasi Algoritma Prim Pada Jaringan Distribusi Listrik Primer Dengan Menggunakan Program Berbasis Gis

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 algorith

This expert system also proved to be able to function properly to diagnose problem of the television set based on the type and characteristics of the damage

Efek Penggunaan Scr Motor Controller Untuk Peningkatan Efisiensi Pada Motor Induksi Tiga Fasa

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

Aplikasi Algoritma Prim Untuk Menentukan Minimum Spanning Tree Suatu Graf Berbobot Dengan Menggunakan Pemrograman Berorientasi Objek

In this study, the algorithm used is Prim's algorithm—an algorithm in graph theory to seek a minimum spanning tree for a weighted connected graph. The program used is a program created with Delphi 7 programming language used for searching the minimum spanning tree of a graph model with the weight of each form of distance/length connecting the points/vertices. Then display the information search process sequence of minimum spanning tree, the total number of minimum length and the resulting computing time to determine the efficiency of Prim's algorithm. Based on the results of research, Prim's algorithm computation time in finding the minimum spanning tree of a weighted graph will grow up along with increasing thenumber of points/vertices and the number of sides of the weighted graph
