Abstract

In this research, we propose hybrid Coarse Wavelength Division Multiplexing/Time Division Multiplexing (CWDM/TDM)-Passive Optical Networks (PON) scheme for optimizing the new technology of Gigabit-PON (GPON) called Next Generation-PON Stage 2 (NG-PON2). The simulation of using this scheme proved that Q-Factor increase and Bit Error Rate (BER) decreased, significantly. We use CWDM scheme for downstream while TDM is used for upstream, and we assimilate both of them with new configuration in bidirectional cable setting. CWDM is used due to low nonlinearity effect like Kerr effects. It has the same working principle based on (Time Wavelength Division Multiplexing-PON) TWDM-PON by differentiating the use of wavelength, it can be easily implemented on existing PON technology, and can be used in single-mode optical fiber (SMF) with greater bandwidth and much cheaper operational costs. From the calculations and simulations, it can be analyzed that the network Hybrid of CWDM / TDM-PON able to work on bit rate of 40/10 Gbps on the number of users 32, 64, and 128, with Q-Factor value is above 6 equal to International Telecommunication Union of Telecommunication (ITU-T) standard. The number of users 32 with two cable lengths of 10 and 20 km have value of Q-Factor 25.960 and 14.815 respectively, while64 users with the same cable length have Q-Factor value of 15.808 and 13.046 respectively. In addition, 128 users with the same cable length have BER value of 17.778 and 12.944 respectively.

Abstract

Next Generation Passive Optical Network Stage 2 (NG-PON2) have to resolve the problem like demand each user, for example, HDTV, 3DTV, Hologram and Telemedicine. The research designed Passive Optical Network (PON), which is meet requirements of NG-PON2. Using stacked 4 Optical Line Terminal (OLT) with an aggregate 40 Gbps transmitted on fiber Single Mode Fiber (SMF) and Dispersion Compensation Fiber (DCF) by comparing the system without DCF cable. On the condition of minimum standards, the range of 40 km with a power splitter 1:64 only 9:01% power difference while the increased in the Q factor of 65.5%. With these results, it can be said that systems using DCF can be used optimally. In addition, with the power splitter 1: 4 and a lower power worth 0 dBm can produce a range of 150% further. With the same distance as far as 40 km, this research increasing power splitter 6 times increase compared with previous research.

Abstract

A predictive model can be learned using historical information. Thereafter, information about a running case is combined with a predictive model to estimate the case's remaining flow time. The predictive model is based on data from past events, which can be used to make predictions for current operating situations. For example, the case of coronavirus disease 2019 (COVID-19), which is currently infecting the whole world, including Indonesia, have influenced various aspects, ranging from the educational environment, business, economy, to the companies. Data scientists are urgently needed who can help organizations improve their operational processes. Therefore, this journal discusses the prediction of the peak number of COVID-19 cases in Indonesia, using two prediction models, logistic and Gompertz. The results obtained show that the Gompertz model has higher accuracy than the logistic model, with an accuracy of 99.85%. This journal's results are expected to help organizations estimate the time to rebuild themselves after being affected by COVID-19.

Abstract

This research detects the random position with received signal strength (RSS) method based on the received power in the room with a size of 5×5×3 cubic meter and several numbers of light emitting diode (LEDs). The first scenario uses 4 LEDs, the second scenario uses 6 LEDs and the third scenario uses 8 LEDs. Random points as the detector are placed spread at the room as many as 25 points. The simulation result shows that the use of more LEDs reduces the positioning error and increases the accuracy. If the accuracy reduces, the positioning error increase and affect the detection results. Using 8 LEDs, the number of the detected random point increases 30%, the positioning error is 47%, and the accuracy increase from 33%.  In addition, our research is useful for finding the locations of small items such as sensors that are scattered in a closed room.

Penelitian ini berfokus pada skema manajemen sumber daya pada sistem Long Term Evolution yang tidak hanya mengejar parameter performansi dasar seperti e?siensi spektral dan fairness sistem, tetapi juga mempertimbangkan aspek e?siensi energi. Penambahan skema kontrol daya water?lling digunakanpadaalgoritmaalokasimeangreedyuntukmengaturdayapadatiap-tiapresourceblock(RB).2Skema yang digunakan adalah normal water?lling (NWF) yang memberikan daya lebih pada user dengan kondisi kanal buruk dan Inverse Water?lling (IWF) yang mengalokasikan daya lebih pada user dengan kondisi kanal baik. Dari hasil simulasi didapatkan skema NWF menaikkan fairness sistem sebesar 10% tetapi menurunkan nilai e?siensi spektral sebesar 1,02 bps/Hz, dan menurunkan e?siensi energi sebesar 68,75 kbps/Watt. Sebaliknya, skema IWF meningkatkan e?siensi spektral sebanyak 1,42 bps/Hz, dan meningkatkan e?siensi energi sebanyak 205,67 kbps/Watt, tetapi fairness sistem menurun sebesar 11%. Dapat disimpulkan, skema NWF baik untuk sistem yang mengedepankan keadilan sistem dan stabilitas koneksi,sedangkan skema IWF lebih sesuai diterapkan pada sistem yang mengedepankan efisiensi.

Abstract

Kebutuhan akan data rate yang tinggi semakin meningkat dalam jaringan telekomunikasi untuk dapat melayani aplikasi high bandwidth yang memuaskan. Dengan meningkatkan kebutuhan data rate, isu konsumsi daya membutuhkan solusi untuk energy efficiency. Energy efficiency telah menjadi aspek yang sangat penting dalam network design karena meningkatnya konsumsi energi pada saat transmisi berkaitan dengan perfomansi dari sistem. Evolusi teknologi Gigabit Passive Optical Network (GPON) ke Next Generation Passive Optical Network stage 2 (NGPON2) merupakan langkah dalam memberikan layanan yang lebih baik karena mampu memberikan peningkatan bandwidth dan quality of service (QOS) untuk layanan konektifitas best-effort high speed dengan lebih banyak split ratio dan jangkauan yang lebih jauh. Dalam penelitian ini akan merancang dan mensimulasikan jaringan Bidirectional NGPON2 dengan teknik TWDM yang memiliki total bitrate 40 Gbps untuk downstream dan 10 Gbps untuk upstream dengan menggunakan kombinasi passive splitter 3 stage pada jarak 30 km. Pendekatan untuk mendapatkan hasil menggunakan perhitungan link power budget, BER dan Q-Factor serta mengacu kepada standar ITU-T.

Abstract

Keterbatasan bandwidth merupakan salah satu permasalahan pada teknologi GPON. Pengembangan teknologi ini terus dilakukan hingga ditemukannya teknologi NG-PON2. NG-PON2 merupakan teknologi yang menggunakan Time and Wavelength Division Multiplexing (TWDM) sebagai solusi utamanya karena mampu meningkatkan bandwidth hingga 40 Gbps. Pada Tugas Akhir ini, dilakukan perancangan dan simulasi jaringan bidirectional menggunakan penguat SOA. Digunakannya empat stacking Optical Line Termination (OLT). Bitrate yang digunakan adalah 10 Gbps untuk downstream dan 2,5 Gbps untuk upstream. Jenis penempatan penguat SOA adalah booster amplifier pada arah downstream dan pre-amplifier pada arah upstream.Berdasarkan dari hasil simulasi, didapatkan bahwa semua nilai parameter performansi berada pada standarnya masing-masing setelah digunakan penguat SOA yaitu pada -28 dBm sampai dengan -7 dBm. Pengaruh pada Power Received adalah meningkakan nilai Power Received yang tanpa menggunakan penguat pada tiap panjang link yang digunakan. Sedangkan pengaruh pada OSNR adalah adanya ketidaklinieran penguatan daya sinyal dan daya noise pada arah downstream yang membuat menurunnya nilai OSNR setelah digunakannya penguat, walaupun masih berada diatas standar OSNR yaitu minimal 30 dBm. Sedangkan pengaruh pada nilai Q-Factor meningkatkan Q-Factor secara efektif yaitu di atas nilai 6 yang membuat nilai Q-Factor dari tiap kanal dinyatakan ideal untuk dijadikan link komunikasi. Sedangkan pengaruh pada nilai BER adalah sama seperti Q -Factor, yang membuat peningkatan dan mengangkat nilainya menjadi di atas standar untuk NG-PON2 yaitu 10-9 karena nilai BER mengikuti nilai Q-Factor-nya. Jarak terjauh yang dapat digunakan setelah menggunakan penguatSOA adalah 65 km.
