Abstract

Communication is the process of delivering information from a node to other nodes. In general, communication in the form of voice and data must be understood by both nodes. Flight data communication is used for pilots to collect information from the devices used. In this research, ARINC 429 data communication system is simulated using visual basic 2010 express. By using a GUI, the input data is obtained from the flight radarpro24 application. The data are representation of altitude and airspeed of Lion Air commercial flight JT922. The 32 bits of binary data are converted into decimal format. It was concluded that the altitude and airspeed data can be read and analyzed using this format.

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

In the development o f wireless communications, to provide high-speed data services and wide bandwidth become a challenge. One technique to make it happen is by using Multicarrier Orthogonal Frequency Division Multiplexing (OFDM) modulation, where in OFDM, frequency selective fading channel effect will be perceived flat fading by each subcarrier. One communication system that supports OFDM technology is Long Term Evolution (LTE) with various types of bandwidth configurations provided. To improve LTE performance in capacity building, coverage area and data rate, it can use multi antenna technique both in receiver and sender, and integrate with High altitude platform station (HAPs) system. In this study the estimation used is Linear Minimum Mean Square (LMMSE). The relationship o f the elevation angle and the K factor is directly proportional, but the elevation angle value is inversely proportional to the diameter o f the HAPs coverage area. In addition, the more the number o f used antennas, the greater the capacity served. Based on the simulation results, the system with estimation can be used to expand the coverage area to 215.77 km which is from 0.032 km in QPSK modulation, speed 60 kmpj with 2x2 antennas.

Abstract

Computer network using LAN has limitations in terms of the large number of computers that will be connected to the switch equipment. This limitation can be overcome by connecting the LAN between each other using a router. Networks inter LAN still pose a problem in terms of safety, although the amount can be overcome. To overcome the problem requires a LAN in a small group that is often known as Virtual Local Area Network (VLAN). VLAN can be connected as is often done on the LAN in general with the addition of some equipment that is able to be used as the connecting or known by the name of inter-VLAN. inter-VLAN configuration can be done directly and indirectly. the configuration directly by configuring the network equipment such as switches and routers, while the indirect configuration can be done using packet tracer. In doing inter-VLAN configuration requires a command performed by an administrator. Commands that is configured on the network equipment is a command that is still a command line or a particular script. For people who have not worked as a network administrator needed a software Graphics User Interface (GUI) for ease in studying network administration. Software Graphics User Interface (GUI) can facilitate a person who has worked as an administrator to configure inter-VLAN.

Abstract

Internet needs in education has become a basic requirement, whether it is for faculty, students, complementary components of universities such as bureaus, public relations, TU, and non-academic staff. As the number of Internet users continues to increase, especially in educational institutions, including STTA’s, an observation of the STTA Internet network data stream is conducted. A parameter to be observed is user's load, as it affects the quality of services that will be generated by the STTA Internet Network.This research provides an analysis to measure the size of user load as well as to know the amount of loss so that it can be a reference in subsequent research to reduce the amount of loss in order to fit in the good category traffic. Model sharing system is used to describe traffic data both elastic and stream at flow level.Observation results show that the average arrival rate of STTA is 11 kbps with average service rate of 59 kbps. This research uses the measured throughput of 86 Mbps. Throughput is calculated from the total number of bits of a successful packet arrivals per second via a network system. With the Internet link capacity of 100 Mbps STTA, after the analysis by the method of sharing system, it is seen that the traffic flow loss is 16%. From this traffic flow loss value, it can be concluded that the STTA’s Internet is include in medium category.

Abstract

Today's wireless communication system is a trend for the information society. This is inseparable from communication needs with high mobility and low costs. One of them is the Wireless Local Area network with the IEEE 802.11 standard. Wireless LAN is a communication technology that uses radio wave transmission media by utilizing free space as a transmission line. The transmitted signal is strongly influenced by distance, frequency, transmitter power, receiver sensitivity, and antenna gain. A loss occurs in the process of transmitting data from the sender to the recipien. In order to no loss that occurs, it requires a good performance, and a wide coverage area. The purpose of this study is to analyze the QoS data, calculate the coverage area, receiver power, and compare the results of theoretical calculations with the measurement results. The analysis results show the average throughput for each data rate of 6 Mbps, 15 Mbps and 35 Mbps at 383.8 kbps, 328.2 kbps and 329.8 kbps. The average delay is 5.28 ms, 4.81 ms and 4.66 ms. The average packet loss is 2.83% ms, 2.66% ms and 2.16% ms. The average jitter is 0.036 ms, 0.032 ms and 0.014 ms.
