Abstract

Pemanfaatan drone merupakan salah satu use cases 5G. Penggunaan teknologi seluler seperti LTE untuk komunikasi drone dapat menawarkan koneksi lebih baik dengan cakupan luas. Penelitian ini menguji kelayakan LTE sebagai sarana komunikasi drone, melalui simulasi NS-3. Reference Signal Received Power (RSRP) dan Signal-to-Interference Ratio (SINR) dianalisis dalam dua skenario. Skenario pertama, pengujian dengan menghubungkan satu drone ke satu base station (BS), dan melihat efek perubahan jarak dan ketinggian terhadap RSRP. Skenario kedua, pengujian SINR downlink dan SINR uplink pada ground User Equipment (UE) akibat adanya perubahan jumlah drone dan ketinggian drone. Simulasi dijalankan pada situasi rural, dengan frekuensi 880 MHz (uplink) dan 925 MHz (downlink). Hasil uji konektivitas single-drone memberikan RSRP yang baik hingga jarak yang cukup jauh, yaitu 60% probabilitas untuk memiliki RSRP >-80 dBm, pada jarak 1000 m. Hasil pengujian studi interferensi ialah pada saat drone berada di ketinggian 200 m, SINR drone lebih buruk dibandingkan saat berada di ketinggian 100 m. Hal tersebut dikarenakan drone mendapatkan interferensi dari BS lain dengan probabilitas Line-of-Sight (LOS) yang lebih tinggi. Sedangkan, nilai rata-rata uplink SINR untuk UE yang berada di daratan tidak terpengaruh dengan perubahan jumlah drone. Drones application is one of use cases of future 5G. LTE networks could assist drone to serve better with a wider coverage. We analyze the feasibility of LTE network for drone communication, in a NS-3 simulator. Reference Signal Received Power (RSRP) and Signal-to-Interference (SINR) was analyzed in two scenarios. For Scenario I, we study the connectivity performance between one drone and one base station (BS), and see the impact of changing distance and altitude. For Scenario II, we study the SINR with changing number of drones and its altitude. Different altitude was analyzed to study the drone’s downlink SINR to serving BS, and different number of drones was studied to analyze the performance of average uplink SINR of ground UE. We use rural scenario, 880 MHz for downlink and 925 MHz for uplink. The single-drone connectivity test provides good result, with 60% probability to have RSRP >-80 dBm at 1000 m distance. For the interference study, the downlink SINR on 100 m height is better than 200 m, since higher drone has higher probability of Line-of-Sight (LOS) communication between drone and interfering BS. The average uplink SINR of ground UEs have no significant impact to the number of drone changes.

Abstract

Deploying network in rural is not attractive for commercial based broadband network providers. However, it is important to provide internet access for villagers since internet may give positive impacts on social development. A failure to forecast traffic demand might lead to a sloppy network design which is inefficient and costly. The mobile traffic demand forecast method needs wider perspectives other than technical records of network providers only. This research introduces a multidimensional model to predict data traffic demand in the future, by combining government spatial planning, demography statistics, and network records. Two different areas were studied and analyzed: Panimbang and Leuwidamar districs, in Banten Province, Indonesia. The main parameter to compare single- and multi-dimensions model is the areal traffic demand. For Panimbang, the areal traffic demand for multi-dimensions model has 24 Mbps/km2 higher, compared to the single-dimension model. For Leuwidamar, the demand for multi-dimension is 10 Mbps/km2 lower, compared to the single-dimension. In case of Panimbang, a pessimistic forecasting might not be a big problem since adding cells in a dense area is not costly, however for the case of Leuwidamar, multi-dimensions models could help to design a more efficient network since the single-dimension model is too optimistic and leads to a high capital investment for providers. This multidimensional model suits best for remote and sparsely distributed users (Leuwidamar). However, it might give no high impact for residential or urban areas (Panimbang).

Abstract

The wide implementation of fibre optic transmission cable supports the increasing demand of datacommunication, due to its reliability and its fast connectivity. However, optical fibre communicationmight experience an outage condition, which could degrade the overall network performance. Thisstudy analyses an eight months data recording of outage tickets for three region networks by usingTableau. We study three main parameters: age of nodes, device models and the number of tickets thataffect the number of outages in each region. Based on these parameters, we identify the top prioritymaintenance nodes in each region that affect the performance the most. We classified the outagecondition based on internal (e.g. breaker down, maintenance), and external (e.g. electricity blackout,cable bitten by animals). Study shows that most outage causes are the “Electricity blackout” whichaccount of 33.33% of total cases. Meanwhile, the region that suffered by outage the most is Jakarta-Central, with only 99,74% Network Availability (NA), compared to Jakarta-Bekasi-Karawang withNA 99,85% and Jakarta-NorthEast with NA 99,86%.

Abstract

Penelitian ini menawarkan solusi untuk akses broadband futuristik di daerah terpencil dan pedesaan dengan pilihan: optimasi LTE; dan perkembangan jaringan pita lebar yang diasumsikan sebagai 5G. Teknologi yang digunakan pada sistem 5G masa depan ialah pemanfaatan frekuensi tinggi, UE-Specific Beamforming, dan Skema Carrier Agregation (CA). Lima klasifikasi dalam implementasi jaringan futuristik: Skenario 1, Single Carrier (SC) LTE 1,8 GHz; Skenario 2, CA LTE 1,8 GHz + 2,6 GHz; Skenario 3, SC 5G 15 GHz; Skenario 4, SC 5G 28 GHz; Skenario 5, CA LTE 1,8 GHz + 5G 15 GHz. Redaman hujan diperhitungkan demi mendapat hasil realistis. Pada wilayah Leuwidamar, Skenario 5 memiliki jumlah BS paling sedikit. Sedangkan di Panimbang, Skenario 3 dan 5 memiliki jumlah BS yang paling sedikit. Namun, jika performansi energi diperhitungkan, Skenario 3 merupakan solusi terbaik. Selanjutnya, jika kita mengimplementasikan Discontinues Transmission (DTX), Skenario 3 dapat memberi kita penghematan energi yang mengesankan, dengan masing-masing penghematan sebesar 97% dan 94% pada daerah Leuwidamar dan Panimbang. Maka, hasil studi menyarankan untuk menggunakan jaringan SC 15 GHz sebagai optimisasi jaringan prospektif masa depan di Leuwidamar dan Panimbang, menimbang tercapainya salah satu target teknis teknologi 5G, yaitu ketersediaan 50 Mbps dimana saja dan kapan saja. *****Our work compared the performance of future broadband network solutions: with Optimized LTE system; and a new enhanced Mobile Broadband (eMBB) system, in which assumed to be prospective 5G network. The proposed eMBB system implements three key-techniques: high frequency, a UE-Specific Beamforming, and Carrier Aggregation (CA). We propose five solutions: Case 1, Single Carrier (SC) LTE 1.8 GHz; Case 2, CA LTE 1.8 GHz + 2.6 GHz; Case 3, SC 5G 15 GHz; Case 4, SC 5G 28 GHz; Case 5, CA LTE 1.8 GHz + 5G 15 GHz. Rain attenuation is considered to aim realistic solution. In the remote area (Leuwidamar), the Case 5 gives the least number of BS, with only 1.6 times densification of the current network. For the rural area cases (Panimbang), it is offered by Case 3 and Case 5 with the same number of BS. However, the best solution in terms of energy performance for both areas is Case 3. With DTX implementation, Case 3 gives an impressive amount of energy saving, with 97% in Leuwidamar and 94% saving in Panimbang. Thus, provided that our assumptions about eMBB techniques are fulfilled the Single Carrier 15 GHz link network is the most efficient.

Abstract

Salah satu pelanggaran hak asasi manusia yang angkanya mencapai 348.446 kasus adalah tindakan kekerasan yang korbannya lebih sering terjadi pada perempuan dan anak-anak. Ada banyak faktor yang menyebabkan terjadinya kekerasan terhadap perempuan dan anak. Salah satunya kurangnya pemahaman masyarakat terhadap perilaku menyimpang yang mereka lakukan. Tujuan penelitian ini ialah menyebarluaskan edukasi melalui animasi 2D untuk memberi pengetahuan terhadap masyarakat agar dapat menghindari tindakan kekerasan. Animasi 2D dipilih karena dapat menjelaskan informasi menjadi lebih sederhana sehingga mudah dipahami oleh penonton. Penelitian ini menggunakan metode DDD-E, yang dalam pembuatannya dilakukan dengan 4 tahapan, yaitu : decide, design, developt, dan evaluate. Dalam pembuatan animasi 2D dibuat storyboard sebagai panduan utama untuk membuat scene yang akan di tampilkan dalam animasi. Hasil dari potongan - potongan scene dalam bentuk video yang nantinya akan di lengkapi dengan audio sebagai sound pendukungnya. Penelitian ini menghasilkan video edukasi animasi seperti memukul, membentak, mencubit, bullying, dan kekerasan pada perempuan seperti KDRT dan penelantaran, yang di dukung dengan media sosial yang bisa di lihat di https://youtu.be/gilnA9GapoU.
