Abstract

Teknologi yang semakin canggih menyebabkan kebutuhan manusia akan kecepatan data sangat tinggi untuk memberikan keseimbangan terhadap teknologi. Upaya untuk menunjang teknologi tersebut menggunakan teknologi Fiber to The Home (FTTH) sebagai transmisinya. Lokasi wilayah yang menggunakan teknologi FTTH tersebut berada di daerah Padalarang, Bandung Barat. Penelitian ini menganalisa serat optik dengan penggunaan splitter 1:8 melalui metode perhitungan Power Link Budget, pengukuran alat menggunakan Optical Power Meter (OPM), serta digunakan aplikasi simulasi Optisystem dan Google Earth. Hasil penelitian didapatkan receive sensitivity Power Link Budget sebesar -16,78 dBm untuk ODP dan -18,79 dBm untuk ONT. Terdapat selisih sebesar 9,18% antara hasil pengukuran dan perhitungan menggunakan metode Power Link Budget pada ODP, sebesar 7,5% antara pengukuran dan perhitungan menggunakan metode Power Link Budget pada ONT, sebesar 3,78% antara pengukuran dengan hasil simulasi Optisystem pada ODP, sebesar 1,97% antara pengukuran menggunakan OPM dengan hasil simulasi Optisystem pada ONT. Berdasarkan pemantauan kelayakan performansi jaringan yang dilakukan selama 2 minggu, didapatkan nilai rata-rata receive sensitivity untuk ODP sebesar -18,32 dBm. Pada ONT dilakukan pengukuran pada port 4,6, dan 8 di perangkat ODP menghasilkan nilai receive sensivity sebesar -19,35 dBm, -20,26 dBm, dan -20,95 dBm. Hal ini menunjukkan bahwa nilai telah memenuhi standar ITU-T G.984, yakni Pr lebih dari -27 dBm. Performansi jaringan Fiber to The Home yang dilakukan di daerah Padalarang, Bandung Barat sesuai PT. Telkom berdasarkan pengukuran yang dilakukan.

Abstract

Banjir adalah bencana alam yang sering terjadi di wilayah Jakarta dan sekitarnya. Salah satu permasalahan yang menyebabkan bencana banjir adalah adanya sumbatan pada saluran air yang menyebabkan air meluap dan menimbulkan genangan. Kegiatan pengabdian kepada masyarakat ini memberikan solusi dengan memberilkan kegiatan pelatihan pembuatan deteksi dini bencana banjir menggunakan deteksi ketinggian air yang diletakkan pada saluran pembuangan air di wilayah Perumahan Jatibening, Bekasi yang mengalami bencana banji diawal tahun 2021. Alat yang dirancang menerapkan teknologi tepat guna dengan memanfaatkan pelampung water level control yang dikoneksikan dengan power supply dan relay sebagai sakelar otomatis. Informasi ketinggian air direpresentasikan menggunakan indicator lampu LED dan jika air sudah meluap maka sirine akan berbunyi untuk memberikan informasi kepada warga sekitar agar dapat segera mengevakuasi barang-barang berharga dan lainnya. Hasil dari kegiatan ini didapatkan bahwa pemahaman masyarakat terhadap deteksi bencana banjir meningkat menjadi 98% dan alat deteksi ketinggian air berhasil diterapkan dan ditempatkan di saluran pembuangan air di wilayah perumahan jatibening, bekasi.

Abstract

MTS Tarbiyatul Falah is a junior high school educational institution that organizes a madrasah-level education program that follows the curriculum set by the Ministry of Education and Culture of the Republic of Indonesia where one of its extracurricular activities is the introduction of basic electronics to students. For that, the urgency of this community service activity is to provide training to teachers at MTS Tarbiyatul Falah to be able to design and realize a temperature control circuit based on Arduino Uno. The purpose of this community service activity is to provide training in the use of tinkercad for basic Arduino programming in order to improve teachers' knowledge in providing materials, especially in the field of electronics. From this activity, the ability and understanding of the training participants increased from 56 to 90 based on the pre-test and post-test. In addition, the satisfaction of the training participants was also very high as shown based on the results of the questionnaire where the average satisfaction was 95%. Therefore, this activity is very useful especially for improving the ability of MTS teachers in designing electronic circuits using Arduino Uno.

Abstract

The increasing number of users in a Long Term Evolution (LTE) network often decreases network performance. A cell that has high traffic experiences a decline in network performance due to unavailable resources for certain users, while in cells with low traffic, the use of resources in these cells is inefficient. The mobility load balancing (MLB) algorithm balances the intercellular loads in an LTE network and improves the performance by distributing part of the load in a high traffic cell to neighboring cells that have low loads. An activated MLB will detect the network load and calculate the available resource for each cell to determine which cells are overloaded. The MLB will consider the candidate cell where the load could be distributed. MLB simulation results show that the application of MLB has succeeded in reducing the percentage of unsatisfied users by 9.4% and increasing throughput system to 5.617 Mbps.

Abstract

One of the most favorable frequency bands for 5G technology is the 27.5 - 28.5 GHz band which has been used by Fixed Satellite System (FSS) service in the uplink direction. This potentially causes interference between the two systems. This study aims to analyze the interference that occurs between satellite earth stations and 5G access points (AP), and between 5G AP and satellite sky stations. The analysis is carried out based on simulations using the Spectrum Engineering Advanced Monte Carlo Analysis Tool (SEAMCAT) software, with two scenarios. The first scenario is to analyze interference between the 5G AP and the FSS sky station. With the C/I interference criterion of 40.2 dB, the simulation results show that the 5G AP will not interfere with the FSS sky station. The second scenario is the interference simulation between FSS earth station and 5G AP. The simulation is carried out by varying the distance between the earth station and the 5G AP, the height of the earth station, and the height of the 5G AP. Based on the simulations, it is shown that the FSS earth station can interfere with 5G AP with a probability of up to 60%, so it is necessary to adjust the distance between systems and the height of the antenna to minimize the interference. The shortest distance needed to minimize interference is 36 km with an earth station height of 5 meters.
