Abstract

Nowdays the application of wireless communication system at the airport area is very important as it is used to support the services and savety of people. In the beginning the communication is done by using Handy Talkie (HT) and the communication is limited on voice. To increase the working operation and savety of public the data communication, besides the voice, is needed. This research is designed to use wireless communication using TETRA technology on frequency 450 MHz by counting the linkbudget and are coverage of the airport. The calculation shows that the more the distance between Tx and Rx, the bigger the pathloss will be. When the distance is 5 km, the pathloss reaches 144,46dBm on the antenna receiver 1,25m. Menwhile the Rx heigh antenna does not have any significance effect on the pathloss. The coverage area for the plan can reach the distance 3,3 km when the power of transmission is 33 dBm which is enough to cover the whole area of the airport.Keywords: TETRA, Link Budget, Pathloss, Airport

Abstract

Deploying femtocells that have low power level in LTE with small coverage area is an alternative solution for mobile operators to improve indoors network coverage area as well as system capacity. However deploying femtocells (HeNB) that were used co-channel frequency, can be brought about interference problem to the Macro BTS (eNB). Close Subscriber Group (CSG) of HeNB allows only User equipment (UE) to access HeNB. HeNB is the source of interference for UE who cannot access it. Therefore it is necessary for interference coordination methods among the HeNB and eNB. The methods are ICIC (Intercell Interference Coordination) and eICIC (enhanced Intercell Interference Coordination).  This paper proposed performance analysis of scheduling schemes for Femto to macro interference coordination that allocated resource in the frequency and time domain using LTE-Femtocell suburban and urban deployment scenario. Simulation result using ICIC methods can improve SINR performance 15.77 % in urban and 28.66 % in suburban, throughput performance 10.11 % in urban and 21.05 % in suburban. eICIC methods can improve SINR performance 17.44 % in urban and 31.14 % in suburban, throughput performance 19.83% in urban and 44.39 % in suburban.The result prove using eICIC method in time domain resource have better performance than using ICIC method in frequency resource. However using eICIC method in suburban deployment scenariocan increase the performance of SINR and throughput more effective than using eICIC method in urban deployment scenario.

Abstract

The cellular subscribers’s growth over the years increases the traffic volume at Base Stations (BSs) significantly. Typically, in central business district (CBD) area, the traffic load in cellular network in the daytime is relatively heavy, and light in the daynight. But, Base Station still consumes energy normally. It can cause the energy consumption is wasted. On the other hand, energy consumption being an important issue in the world. Because, higher energy consumption contributes on increasing of emission. Thus, it requires for efficiency energy methods by switching BS dynamically. The methods are Lower-to-Higher (LH) and Higher-to-Lower (HL) scheme on centralized algorithm. In this paper propose cell zooming technique  which can adjusts the cell size dynamic based on traffic condition. The simulation result by using Lower-to-Higher (LH) scheme can save the network energy consumption up to 70.7917% when the number of mobile user is 37 users and 0% when the number of mobile user is more than or equal to 291 users. While, Higher-to-Lower (HL) scheme can save the network energy consumption up to 32.3303% when the number of mobile user is 37 users and 0% when the number of mobile user is more than or equal to 292 users. From both of these schemes, we can analyze that by using Lower-to-Higher (LH) scheme reduces energy consumption greater than using Higher-to-Lower (HL) scheme. Nevertheless, both of them can be implemented for energy-efficient method in CBD area. Eventually, the cell zooming technique by using two schemes on centralized algorithm which leads to green cellular network in Surabaya is investigated.

Abstract

Over time, cellular communication technology developed significantly from year to year. This is due to increasing the number of users and the higher needed. To overcome this problem, many providers increase the number of new base station installations to fill up the customer's needed. The increase number of base stations does not take into account the amount of power consumption produced, where in the cellular network Base Stations (BS) are the most dominant energy consuming equipment estimated at 60% - 80% of the total energy consumption in the cellular industry. In addition, energy waste often occurs in the BS where the emission power will always remain even if the number of users is small. Power consumption and energy savings are important issues at this time because they will affect CO2 emissions in the air. This paper proposes to save energy consumption from BS by turning off BS (sleep mode) if the number of users is small and distributed to other BS (neighboring BS) which is called cell zooming technique. The cell size can zoom out when the load traffic is high and zoom in when the load traffic is low. To determine the central BS and neighboring BS, a sequential to better signal (SBS) scheme is used where this scheme sorts neighboring BS based on the SINR value received (user). The results of this research, base station can be able to save energy 29.12% and reduce CO2 emission around 3580 kg/year. It means saving energy consumption which is also reducing air pollution occurs and this term can be named as green cellular network.

Abstract

In the case of an accident, a prompt response is needed to prevent accidents or provide assistance to traffic accident victims. Several ways can be carried out to address this problem. One of them is by developing several smartphone applications for accident detection and accident notification that provide aid in traffic accidents. The existing application to assist the victims merely presents the shortest route from the respondent to the victim’s location without any features that help the respondent find a route to the nearest hospital and police station. Therefore, this study develops a smartphone application for accident alerts for victims’ relatives and respondents, which assists in locating the victim’s position and the closest hospitals and police stations. This accident notification app for smartphones utilizes open-source software and is very scalable. The outcome of this study is an Android application capable of sending accident notification broadcasts, allowing the victim’s relatives and respondents to get accident notifications and drive to the accident place using the route given by the application. In addition, the developed app also provides information about the location of the nearest hospital and police station, allowing respondents nearby the location to help the victim promptly. The results of testing the application using the black box method on the Android platform indicated that 100% of the features of this application were running well. The shortest route with the Floyd-Warshall algorithm was 4.199 km, with no route deviations from the distance testing scenario. The average speed of notification delivery response from victims to respondents was 27.86 ms.

Abstract

Sektor pertanian memegang peranan strategis dalam pembangunan nasional di Indonesia karena berfungsi sebagai penyedia bahan pangan, instrumen pengentasan kemiskinan, penyedia lapangan kerja, dan sumber pendapatan masyarakat. Aspek yang penting di sektor pertanian adalah sistem irigasi. Saat ini monitoring saluran irigasi yang dilakukan masih menggunakan cara manual. Akibat dari lokasi sawah dan rumah petani yang jauh, hal ini dapat menimbulkan kerugian materil dan mengganggu pertumbuhan tanaman. Pengabdian masyarakat ini melakukan implementasi prototipe sistem berbasis teknologi yang mampu memonitor informasi debit air pada saluran irigasi. Prototipe sistem dikonfigurasi menjadi sebuah web server yang juga menyimpan data volume air dalam rentang waktu yang telah ditentukan dan dapat dikomunikasikan menggunakan wireless. Komponen yang digunakan dalam pengujian ini adalah sensor dan mikrokontroler ESP32 sebagai inti yang menggunakan bahasa pemrograman php serta menggunakan protokol M2M untuk melihat kondisi air secara realtime. Sehingga informasi debit air untuk irigasi disimpan pada database dan ditampilkan melalui website. Hasil output yang ditampilkan pada website adalah data debit air dalam bentuk angka dan grafik yang akan memudahkan pembacaan. Hasil tersebut diharapkan dapat berfungsi sebagai monitoring informasi debit air agar dapat memudahkan para petani dalam memonitor dan mengontrol masuknya air dalam saluran irigasi sehingga dapat meningkatkan produktivitas pertanian khususnya di wilayah pedesaan.
