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

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

ABSTRAKSistem komunikasi dikembangkan untuk peningkatan ekonomi nelayan. Penelitian yang dikembangkan sistem komunikasi antar nelayan dengan pesisir pantai dengan biaya murah serta mempunyai jangkauan jarak yang terbatas. Untuk mengatasi jarak jangkauan jauh maka pada penelitian ini mengimplementasikan sistem komunikasi Lora multihop menggunakan telemetri dengan daya transmisi 24 dBm atau 250 mW. Sistem ini terdiri blok end device berupa telemetri berada pada kapal nelayan, blok gateway pada pinggir pantai, dan blok server application pada end user serta tampilan berupa website nelayan. Hasil pengujian telemetri sebagai transceiver dengan komunikasi multihop mampu digunakan untuk pengiriman data menghasilkan daerah jangkauan 7,2 km menjauhi pantai. Telemetri mengirimkan data ke gateway di pantai kemudian data diteruskan ke server cloud sebagai database. Perancangan database menggunakan model data relasional dan pengolahan data menggunakan algoritma FIFO. Hasil pengujian performansi sistem pada pengujian aplikasi front-end dan back-end menunjukan bahwa performansi sistem mampu menangani permintaan user secara cepat.

Research created an inexpensive distance-restricted communication system for fishermen and coast. This study uses telemetry with transmission strength of 24 dBm or 250 mW to create multihop Lora communication in order to cross great distances. This system comprises of gateway block on coast, application server block on end user, display in form of fisherman's website, and end device block in form of telemetry on fishing boat. Using findings of testing telemetry as transceiver with multihop connection, coverage area of 7.2 km can be employed for data transfer. Data is transmitted from telemetry to coastal gateway and then sent to cloud server where it is stored as database. FIFO algorithm are used relational data modeling and data processing in database design. System's ability to handle user requests rapidly is demonstrated by results of front-end and backend application testing for system performance.Keywords: Telemetri, Lora, Multihop, Application, Coast

Abstract

Permasalahan kualitas udara di kawasan perkotaan semakin serius akibat pembangunan, industrialisasi, dan padatnya jumlah penduduk. Masalah ini berdampak pada kesehatan masyarakat, seperti penyakit pernapasan dan gangguan jantung. Pengabdian masyarakat ini bertujuan memberikan informasi akurat tentang kondisi udara perkotaan dan meningkatkan kesadaran masyarakat akan pentingnya menjaga kualitas lingkungan. Sistem pemantauan kualitas udara berbasis teknologi dikembangkan menggunakan sensor multi-in-one RK300-08, yang mengukur berbagai parameter polusi udara, seperti karbon monoksida (CO), ozon (O₃), sulfur dioksida (SO₂), nitrogen dioksida (NO₂), serta partikel debu halus (PM2.5) dan lebih besar (PM10). Data pemantauan diproses dengan mikrokontroler ESP32 dan ditampilkan real-time melalui dasbor web yang dapat diakses masyarakat. Sensor ini dipilih karena kemampuannya yang komprehensif untuk mengukur parameter udara yang berbahaya bagi kesehatan. Hasil implementasi menunjukkan bahwa informasi yang diberikan cepat, akurat, dan terintegrasi, lebih efisien dibandingkan metode konvensional seperti Indeks Standar Pencemaran Udara (ISPU) yang tidak memberikan informasi waktu nyata. Evaluasi dampak sosial menunjukkan peningkatan kesadaran masyarakat yang lebih proaktif dalam mengambil langkah preventif, seperti mengurangi aktivitas luar ruangan saat udara buruk. Dengan sistem ini, masyarakat dapat berpartisipasi langsung dalam pemantauan lingkungan, mendukung terciptanya lingkungan yang lebih sehat dan berkelanjutan, serta menunjukkan potensi teknologi IoT dalam mengatasi masalah lingkungan di kawasan padat penduduk.
