Abstract

5G New Radio (NR) services can provide high data rates and low latency. The existence of 5G technology, especially in Indonesia, has been implemented by several cellular operators in the 2300 MHz and 1800 MHz frequencies. Therefore, a more detailed planning analysis is needed, especially in urban areas. In this study, planning for the 5G network needed in one of the urban areas in Cimahi City, West Java. This research was carried out for a frequency of 2300 MHz using the coverage planning analysis method. The propagation model used in this study is 3GPP TR38.900. Based on the analysis and calculations performed, obtained 26 sites for the area of ​​Cimahi City which has an area of ​​about 40.3 km². The location of the site is arranged based on the coverage conditions in the area and also based on the distribution of the 4G network that previously existed in the area, because the 5G planning used is the Non-Standalone 5G type. Based on the results of the coverage analysis carried out, the condition of the Synchronization Signal Reference Signal Received Power (SS-RSRP) signal level above -90 dBm reached 27.3% of the total area. This shows that the 5G network planning in this area can only cover an area of ​​up to a quarter of the total area.

Abstract

The occurrence of a malfunction at the substation results in power outages and losses in the electrical energy distribution system to consumers. Many tests are carried out to see the performance of the protection system, including the parameters of the over current relay (OCR) and ground fault relay (GFR) in the electrical energy distribution system. This research aims to analyze OCR and GFR values, analyze OCR setting, drop-off, and pick-up values, and analyze OCR time characteristics using DigSilent Power Factory 15.1 software based on existing equipment specification data at the Braga substation. The results show an OCR accuracy level of around 94% on the 20 kV and 150 kV sides. Meanwhile, 92.39% on the 20 kV GFR side and 94.87% on the 150 kV side. The setting value for the pick-up current is 0.92 A on the 20 kV side of the GFR and the drop-off current is 0.85 A on the 150 kV side with a pick-up current of 0.39 A and a drop-up current of 0.37 A. Setting a value on the 20kV side is greater than on the 150 kV side due to the difference in current transformer ratio values. The simulation results show that the OCR and GFR characteristic curves on both sides meet the criteria for a protection system with good performance.

Abstract

Kebutuhan akan layanan komunikasi dan informasi meningkat pesat. Teknologi 4G diharapkan memenuhi kebutuhan akan kecepatan jaringan yang optimal, tetapi menghadapi kendala yang mempengaruhi kualitas jaringan. Namun, teknologi 4G ini memiliki beberapa kendala yang menyebabkan kecepatan jaringan tidak optimal sehingga perlu dilakukan optimasi untuk memperbaiki hal tersebut. Penelitian ini mengoptimalkan kondisi level sinyal Reference Signal Received Power (RSRP) di Jalur Tol Cikopo-Palimanan (Cipali). RSRP adalah indikator penting untuk menilai kekuatan sinyal dari base station, dimana nilai rendah menunjukkan sinyal yang lemah atau terganggu. Proses optimasi dilakukan dengan menganalisis nilai RSRP berdasarkan data antenna beserta parameter dan disimulasikan di Atoll Planning Software dengan menggunakan metode physical tuning. Berdasarkan hasil data yang didapatkan terdapat beberapa 4 area spot yang memiliki coverage yang kurang baik dengan level RSRP dibawah -90 dBm. Optimasi dilakukan di 4 spot yang mempunyai kondisi level sinyal dibawah -90 dBm dengan menggunakan metode physical tuning, yaitu berupa pengaturan dan perubahan derajat tilting dan arah antenna agar mendapatkan level sinyal dan daya pancar yang lebih baik. Setelah dilakukan optimasi, terdapat perbaikan level sinyal RSRP dimana terjadi kenaikan persentase untuk level sinyal diatas -90 dBm dari 88,73% menjadi 90,67% dan penurunan persentase untuk level sinyal dibawah -90 dBm dari 11,27% menjadi 9,33%.   Abstract The rising demand for communication and information services necessitates optimal network speeds, typically met by 4G technology. However, impediments often hinder network quality. This study focuses on optimizing the Reference Signals Received Power (RSRP) along the Cikopo-Palimanan (Cipali) Toll Road. Using data analysis and simulation in Atoll Planning Software, the physical tuning method is employed to enhance RSRP signal levels. Results reveal several areas with subpar coverage, indicated by RSRP levels below -90 dBm. Optimization efforts concentrate on these areas, adjusting antenna tilting and direction to improve signal strength. Post-optimization, signal levels improve, with a rise in levels above -90 dBm from 88.73% to 90.67%, and a corresponding drop in levels below -90 dBm from 11.27% to 9.33%. This optimization aims to ensure superior communication services for users.
