Abstract

The development of science and technology, especially information technology, internet use in education continues to grow. Use of the Internet is not just for distance education, but also developed in the conventional education system. E-learning is a learning model that is created in digital format through an electronic device. Purpose of the use of e-learning in the learning system is to expand access to education public, so that learning modules can be accessed easily, without diabatasi space and time, interactive, and effective. In this paper a prototype using a software development methodology that emphasizes the approach to aspects of design, functionality and user-interface. The final product is expected to be a module-based learning application of information technology. Key words: Internet, the quality of education, information technology, e-learning

Abstract

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 the number of points/vertices and the number of sides of the weighted graph.   Keywords:Prim’s Algorithm, Graph model, Minimum Spanning Tree

Abstract

The problem in this study were: (1) how the intensity of pollution sector in the region polluted insulator, (2) how polluted insulator surface conductivity Parent substations in each region, (3) how to profile an appropriate insulators for substations with different levels of intensity of pollution sector in the region. To solve this problem pollutant sampling conducted on ceramic insulators on the channel milestone substation switchyard each region at two different points, namely at the top of the insulator and the bottom fin insulators. The results showed the intensity of pollution for every region of substation at a concentration of 0.50 g / l has a value of ESDD with dissolved heavy pollutant levels (> 0.1 mg/cm2), while the value of NSDD categorized insoluble low-level pollutants.

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.

Abstract

Sigi is one of the youngest district in Central Sulawesi province was divided in 2008. Of the 152 villages, 10 villages are experiencing conflicts between residents. Bora Village and Village Vatunonju which is approximately 20 km from the city of Palu is 2 villages among the 10 villages that are often in conflict. Sources of conflict in general stems from a fight between youth. Increasing the number of teenagers who drop out of school temporarily limited employment is one of the problems that often lead to fights among youth. The low work skills possessed by the youth of this area is an issue that must look for solutions so that they can open up and explore job opportunities. This training aims to provide job skills for young people who are still out of school age. With a working capital given the skills they are expected to open and fill vacancies in areas Sigi continues to build. The training activities carried out for 8 months and was attended by 20 people. After the activity the participants are able to operate Microsoft Word and Excel. Although not all of the material provided can be controlled but this training provides many benefits. Especially for trainee electrical installations are already some people who often help people when there are problems in their electrical istalasi, there's even working at the company electrical installer. Keywords : computer, electricity, conflict

Abstract

This paper presents a method to control Permanent Magnet Synchronous Motor (PMSM) at high speed above the based speed. To control PMSM from zero speed up to base speed, the armature voltage of the motor may be varied up to maximum voltage allowed of the inverter used. In this region the stator voltage will increases with the increases of motor speed reaches the based speed, motor voltage cannot increase anymore because of saturation and consequently motor speed cannot be increase more highly. In order motor to control the motor above base speed, it is can be done by weakening the field flux of the rotor. As the rotor made of permanent magnet, then filed weakening control cannot be done directly. The control of field-weakening effect is done by controlling stator current vector of direct axix, which is variable with speed. Keyword: Permanent Magnet Synchronous Motor (PMSM), field flux, increases of motor speed.

Abstract

Almost people in Indonesia ever seen quiz who wants to be millionaire. That quiz is sometimes using a polling method to get the right answer. Audience at studio must help a quiz’s participant by using keypad to get a right answer. Audience must push the button of   keypad where there is choice of answers. After that the answer will be display in a bar graph of percent. This called electronic polling system. With the aim of the research is to design and build a polling system with 6 slave-based serial RS-485, USB and microcontroller RISC and design and build a control system based serial RS-485, USB and microcontroller RISC efficient. The method used in this research is to study the reference, namely collecting materials that can be used as a reference, observation and study references required, inventory problems and needs in the design and manufacture, design and manufacture of hardware, software design and manufacturing, and perform testing. RS-485 is standard for communication with very long cable. This standard can use cable almost 1,2 Km long. RS-485 is very unique, this standard using master slave method. So only the master can control slave. Slave is using a microcontroller to manage data. AVR ATtiny2313 is a good microcontroller for slave. This is microcontroller very small and very fast. Base from design, implementation and test result indication implement of  RS-485 at polling system can be handle of case distance between master and slave. Beside that not only one slave can be connected to master. Keyword : polling system, USB, RS-485, AVRATtiny2313
