Abstract

Semua kekuatan militer di seluruh dunia saat ini memiliki ketergantungan yang sangat penting pada data Positioning,  Navigation & Timing (PNT) yang diperoleh dengan menggunakan Global Positioning System (GPS). Ketersediaan data PNT yang diperoleh dari perangkat GPS pada kapal Perang Republik Indonesia (KRI) akan sangat berpengaruh pada penentuan posisi kapal, data navigasi serta ketersediaan referensi waktu yang digunakan oleh perangkat navigasi dan SEWACO (Sensor, Weapon and Command). Dalam penelitian ini kami merancang suatu sistem pertahanan terhadap GPS jamming pada kapal perang Republik Indonesia dengan menggunakan perangkat gyro inersial sebagai backup data PNT apabila GPS dalam kondisi terjamming melalui Data Distribution Unit (DDU). Analisa dan percobaan sistem tersebut dilaksanakan secara langsung di KRI sehingga hasil dari penelitian ini dapat diterapkan secara langsung pada sistem sewaco. Dari hasil percobaan, DDU dapat melakukan auto switching data PNT dari perangkat GPS ke perangkat gyro inersial apabila GPS dalam kondisi terjammer dan mendistribusikan data tersebut dengan format NMEA-0183. Dari analisa terhadap akurasi dan presisi terhadap gyro inersial, data PNT gyro tersebut memiliki nilai HDOP sebesar 0,695 dengan peak of error horizontal sebesar 2,62 meter dan standar deviasi (latitude/longitude) sebesar 0,742 meter / 0,861 meter.

Abstract

The need for LCD projectors is very urgent, so even though they often experience shortcomings, it is impossible to continue to make purchases when needed to repair LCD projectors that require high costs such as buying a new device. Software development from the results of this study is not only beneficial for educational institutions but also for personal or specific institutions and institutions who want to conduct seminars, presentations, or other activities that involve many audiences. The advantage is that the audience will not experience problems such as when using an LCD projector, such as limited visibility, location or space, and the viewpoint of the audience on the Projector LCD / Screen. Another contribution that can be given from this research is a model of the teaching and learning process in real-time without using an LCD and only using a PC/ Laptop connected to the same LAN. It is a development of research that supports the concept of green computing because it also reduces the use of equipment LCD projector, but the usage function remains the same even more effective and interactive even without the device. Presentation model like this is the development of new models in the learning process using LAN networks but without using the internet connection and is the cross-platform model. This research can be the answer to the need for using LCD projectors that often occur in the process of education, meetings, or seminars that continue to increase every time. Also, the lack of LCD compared to the number of teaching needs in each class and the unstable electricity conditions and the low electricity ratio in East Nusa Tenggara, have resulted in frequent blackouts suddenly, so that makes the device LCD vulnerable to damage. The test results showed an increase in RTT along with the increasing number of servers conducting presentation activities. Testing on LAN networks with the same number of clients on each test shows that there was an increase of 18% and 75% in each addition to the number of servers. The best performance of Powerplan is still shown when the number of servers that present several five, with the response time of each client connected under two seconds.

Abstract

In this paper, we present a mathematical analysis on the performance and behavior of uniformly distributed and non-uniformly distributed backoff timer based on binomial algorithm by using two standards which is the conventional DSRC and the latest Wi-Fi Direct. DSRC is a well-known technology being considered as the most promising wireless standard in VANET. On the other hand, as the latest wireless networking standard, the potential of Wi-Fi Direct technology should be concerned. We evaluates these standards using uniform and binomial distribution for contention window under mathematical modelling in order to analyze the average throughput and collision probability performance. The results show that binomial distribution in Wi-Fi Direct standard is 7.05% and 97.13% better than uniform distribution, in terms of average throughput and collision probability, respectively. Thus we can defer that Wi-Fi Direct is feasible to be used as an alternative standard since it has been considered as potential competitor of DSRC in VANET.

Abstract

When disasters occurs, cellular network might be down and cannot serve subscribers anymore. Meanwhile, many victims trapped in a wreckage might still have access to their mobile phone. An OpenBTS-based cellular network has been long before known as an ideal solution to rapidly deploy emergency GSM cellular network in situation after disaster. In this work, the methods which enable OpenBTS to assist the search for victims was developed. On the other hand, OpenBTS can also provide phone and SMS services so that victims can communicate with rescue teams who are conducting the search process. The voice and SMS services between victim’s mobile phone and SAR team’s smartphone were tested. As a result, phone service can be done by routing calls from victim’s cell phones in OpenBTS network to SAR team’s smartphone in wireless LAN networks. Thus, the SMS data from victim’s mobile phone can be stored in the database system. SMS data can then be accessed using a database browser.

Abstract

The study of surface wind characteristics in the airport area is needed to support flight operations in terms of safety and economy. Surface wind data is required during the aircraft take-off and landing phases. The information on surface wind characteristics is used for flight operational planning or the construction and expansion of an airport runway. To be able to know the description of the monthly surface wind profile in the airport area, the frequency distribution method is very appropriate to use. Research on surface wind patterns with the frequency distribution method in the Soekarno-Hatta Airport area over the past ten-year period shows that January - April the surface wind direction is dominated from the west, May - September is dominated from the east. The months of October, November, and December are a transition from the east to return to the west which is dominated from the south and southwest. This is in line with the general pattern of Indonesia's climate which is influenced by the west monsoon and east monsoon phenomena.
