Abstract

Air conditioning is effort to give comfort and freshness. Air conditioning is needed to absorb heat from a room and to create comfort environment in a room. Air Conditioning (AC) Split Duct is used to create comfort environment that AC Split Duct can supply fresh air into the room that needed it. Fresh air supplied to circulating the air in the room to keep quality of air in the room. Source of polluter can be from inside of the room or outside. Polluted air from the room discarded through return then to exhaust duct while polluted air from outside of the room strained through filter media. Conditioned Air by AC Split Duct distributed through supply duct to the room. Conditioned air enter the from via diffuser. Air in the room exit through return grill then some of returned air circulated back to AC Split Duct and the rest exit through exhaust duct. This design will tested through software, Ansys CFX. Ducting system and Simulation of Air Conditioning Process in the Dining Room at Tower-II Dormitory will be tested.

Abstract

Based on the condition nowadays, the lighting systems in electrical power system simulator building has not reached with the standard recommended by Indonesian National Standard (SNI) 03-6575-2001 which the average standard is 500 lux for the laboratory building. To reach the standard, light intensity in electrical power system simulator is necessary to redesign the lighting to fit with the SNI. The theory used in this research is about the theory of lighting, the calculation of lighting levels, etc. In this research, the writer discuss about the design of the lighting in the electrical power system simulator building with recalculate manually using the standard formula in accordance with the SNI, after getting the results of manual calculation, then the calculation is simulated in a Dialux software version 4.12. The output of this Dialux software can display the illumination simulation in the room area and work area. This research is expected to applied immediately so that the intensity of the lighting on the electrical power system simulator building appropriate with the recommended standard lighting by SNI.

Abstract

Many problems in electrical circuit analysis are widely used mathematical models in their completion. The mathematical model is then formulated numerically in the Linear Equation System. The linear equation can be solved using several Numerical Methods, namely the Gauss Elimination Method, the Cramer method, the Inverse Matrix Method, the Gauss-Jordan Elimination Method and others. To calculate m equations with an unknown number of n variables from large and complex systems, it takes a long time and is not efficient. to complete large and complex mathematical calculations with an easy way to use the Scilab program. At this writing the authors limit only the completion of the Linear Equation System using Scilab with the Cramer Method.

Abstract

The Linear Equation System is often used in solving problems - completion of electrical circuits. The linear equation can be solved using the GaussJordan Elimination Method. The procedure for the Gauss-Jordan elimination method is to transform linear into an augmentation matrix (A|B), then convert matrix A to an identity matrix by reducing the augmentation matrix. To calculate m equations and n independent variables by unknown number of a large and complex system, it takes a long time and is not efficient. The implementation of the Gauss-Jordan Elimination method using the Scilab Program can help complete a large and complex Linear Equation System in a fast and accurate way.
