Abstract

Induction motors are one type of electric motors that work based on electromagnetic induction. The problem that often arises lately is the occurrence of voltage imbalances. Unbalanced voltage is a voltage value that is not the same in a three-phase voltage system contained in the electrical power system. On the basis of these problems, it is necessary to conduct research that can analyze the dynamics of the performance of an induction motor. Dynamic analysis is done by modeling a three-phase induction motor using an arbitrary reference frame with the direct qudrature transformation method in Matlab/Simulink. In studies with voltage imbalances up to 5%, electromagnetic torque has decreased by 2.89% to 13.83% and stator current in one phase has increased by 29.1% to 245.8%.

Abstract

The library is a place that is used as a study and reading room, so that a comfortable place is needed from disturbances in the library building. Based on the decision of the Minister of Environment in 1996, the standard noise for library environments ranged from 45 to 55 dB. but in fact there is often a commotion caused by visitors. in this study a noise level detection system was created where the noise detection system is expected to be used as a media for comfort control in the library room. The noise level detector uses a sound sensor that is connected to Arduino.The system will be equipped with a warning system in the form of Buzzer and Warning Text sounds that will be displayed on the P10 LED Panel and equipped with Internet of Things technology that allows the supervisor or guard of the library to monitor the noise of the library room real time via Web Server. The test results show that this tool can detect noise levels in the range of at least 41 dB and a maximum of 69 dB with a deviation of 0.6 and an average error of 1.0%. the average sound intensity measured in the library room is 56.24 dB. The average percentage of the success of the system against Buzzer and Warning text warnings is equal to 97.3% and the average percentage of the success of sending data to the web server in the noise level detector is 95%

Abstract

Voice is one of  way to communicate and express yourself. Speaker recognition is a process carried out by a device to recognize the speaker through the voice. This study designed a speaker recognition system that was able to identify speakers based on what was said by using dynamic time warping (DTW) method based in matlab. To design a speaker recognition system begins with the process of reference data and test data. Both processes have the same process, which starts with sound recording, preprocessing, and feature extraction. In this system, the Fast Fourier Transform (FFT) method is used to extract the features. The results of the feature extraction process from the two data will be compared using the DTW method. Calculations using DTW that produce the smallest value will be determined as the output. The test results show that the system can identify the voice with the best level of recognition accuracy of 90%, and the average recognition accuracy of 80%. The results were obtained from 50 tests, carried out by 5 people consisting of 3 men and 2 women, each speaker said a predetermined word

Abstract

The Flight Deck or cockpit is designed to support the prosecution of aircraft mission.  For aircraft with commercial purpose such as passenger transport aircraft, there must be good ?fit? between the human, the machine which composed of various aircraft system and the aircraft mission; and these are what the Flight Deck design process needs to ensure but not limited to display design, aircraft control, automation, HCI on the Flight Deck and pilot?s view to outside through cockpit windows namely external vision. The external vision must satisfy regulatory requirements which intended to ensure that the view is adequate for pilots to operate the aircraft safely and gives them a reasonable opportunity to see and avoid other aircraft that pose a collision threat. Concurrently during critical periods of flight, it is important that the flight crew access information in front of his view with minimal head rotation.  Cockpit-Displays with critical flight information should then be located to these locations.  Compromising both external vision and internal vision as Pilot?s visibility should be attained.

Abstract

Micro Hydro Power Plant (PLTMH) is one way to provide electricity, especially for remote areas far from the PLN network.PLTMH utilizes the flow of water to produce electricity. The purpose of this study is to increase the power produced by utilizing two generators that are installed in parallel with the gear box and pulley positions adjusted.This study uses two generators, namely generator A and generator B with a capacity of 3kVA per generator.Data retrieval is done in two ways, namely by loading and without burden. The method of loading is to add a load of incandescent light.Whereas no load is carried out by measuring the output voltage only.Based on this study, the results obtained were at generator A of 225 volts with pulley rotational speed of 2584 rpm.While the results on generator B amounted to 185 volts with pulley rotating speed of 1765 rpm.

Abstract

The limited ground marshall, yellow line and others at an airport will affect when parking aircraft. Aviation technology has provided solutions, among others, by attaching to aircraft equipment known as the Visual Docking Guidance System (VDGS), is a tool provided by the airport to help a pilot park his plane without the help of a marshaller to direct the movement of planes to the  correct parking. However, not all airports are equipped with sophisticated equipment. So this research aims to create a system that can make it easier for pilots to park aircraft while in Apron. To overcome this problem, a VDGS tool was designed which was designed using a TF Mini Lidar sensor and programmed for aircraft parking systems at pioneering airports. This tool is able to provide information on the distance of the plane as far as 12 meters given a condition that the aircraft will display identification of guidance or collision prevention that will STOP if the aircraft is at a distance of 1-3 meters, and GO identification if the aircraft is at a distance of 4-12 meters so that this tool can serves as a guide to the position of the aircraft when parking right in the designated parking area and prevent aircraft crashes when parking when entering the apron area at the pioneer airport.

Abstract

Optimizing the solar cell output power requires a tracker. The tracker which produce a maximum output power is called a maximum power point tracking (MPPT). In this research, each component in MPPT is modeled into Simulink. By using a perturb and observe (P & O) algorithms, this simulation is designed to optimize the solar cell output power. The output of the algorithm is a duty cycle. This parameter is fed into a buck-boost converter to convert the solar cell output voltage to the output voltage. The simulation results show that MPPT can increase the output power up to 37.82% dispite of the sun irradiation, temperature and load changes.

Abstract

Electricity is one of the basic needs of the community. The ability of PLN to provide electricity to the Indonesian people is still an obstacle and a challenge. On the other hand Indonesia has so much potential for water that has not been utilized optimally, which is around 75,000 MW and which is currently utilized only at 10.1% or 7,572 MW. Micro hydro power (MHP) with each 5 MW MHP in 2014. This study aims to utilize the remaining water flow from the existing mill for the installation of the second wheel to obtain maximum power. Experiments were carried out using equipment such as embedded iron fast pipes, waterwheel 1 and 2, pulleys, and generators. Installation on the end of the pipe against pin 1 uses the over-flow method to obtain optimal power. The average rotation speed of the generator for mill 1 is around 1500rpm and for the mill 2 around 1000rpm. The final result of this study, for generator 1 on wheel 1 can run smoothly and produce the appropriate output voltage of 220V, for generator 2 the generator 2 the output generator cannot be optimized because the generator component we use requires a minimum of 1500rpm to run it.
