Abstract

Central Sulawesi has tropical climate conditions with interconnected rivers caused each of it can experience the impact of the sudden rise of water levels if there is a heavy rainfall in upstream areas which is commonly called “a sent flood”. Therefore, it is needed an early detector flood tool that works based on the height of river water level so that the impact of floods can be minimized. Early detector flood tool can function automatically by giving early warning when water levels reach a certain limit. The detector of height levels of river streams is designed using float magnetic level gauge method. This height level of river streams detector is able to provide information in real time based on the height level of river streams by giving information in the form of warning light indicator and siren alarm as alert and danger sign.

Abstract

Supplier selection is multicriteria problem, since for selecting the supplier who will become partner, decision maker must consider many criteria to measure supplier performance. One of the models that is used to measure supplier performance is Supplier Performance Rating used in Kingston-Warren Corporation. The key aspects related to that model are Quality, Cost and Delivery. One of tools that used by decision maker to select supplier is making a computer system that can interact with decision maker. The system is called Decision Support System (DSS) for supplier selection. The process of supplier selection uses Analytical Hierarchy Process (AHP) model. AHP model conduct supplier selection by making paired matrix comparison from defined criterion. Result of AHP model calculation is in the form of priority value, so that the highest priority value produced by the model is used by decision maker to choose the best candidate supplier.

Abstract

Development of an area, such as Yogyakarta is directly proportional to consumption of power in that area. Transformer of 150 KV Wirobrajan substation, 60 MVA, is one of main equipment in power system. Load forecasting on this research using daily average peak load data during five years that is since 2003 to 2008. Based on the analysis of the result of exponential model approach method, the equation Y = 5.29 e 0.04057X is obtained. By using this model, it is found that average load growth forecasting of the transformer during 2009 to 2025, is suitable to supply 50.89 MVA of load demand (85% of full load). Moreover,model Y = 20.18 + 0.44X1 + 0.07X2 is found using polynomial method. In 2025, the transformer, based on polynomial method,can deliver power 80.07 MVA (about 80.07% of full load). Finally, load current was 230.72 A, in 2025.

Abstract

This research is intended to design software that is able to simulate the basic commands of the computer network. Simulation program is planned to serve for people who do not understand about computer networks and have a strong desirelearning the basics of computer networks. The design result of this research is command of ping, telnet, ftp, route, andifconfig. The design of the simulation program also produces 10 units or classes that contain the components of the specificactivity or program.

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 maximumvoltage 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
