Abstract

The implementation of 5G cellular technology in Indonesia needs to be studied in several aspects. So that several cellular operators in Indonesia have experienced difficulties in implementing 5G cellular technology in Indonesia, especially in Pontianak City. Therefore, the analysis of pathloss values in cellular systems is an approach to large-scale fading aspects to calculate service coverage. This research calculates the pathloss value with a case study in Pontianak City with micro urban cell characteristics. In this research, ABG (Alpha-Beta-Gamma) prediction model is used with working frequency of 3.5 GHz and 28 GHz with bandwidth of 100 MHz. The calculation results of the ABG prediction model at a frequency of 3.5 GHz has a value of 91.78 dB for LOS conditions and in NLOS conditions has a value of 123.26 dB. While at a frequency of 28 GHz the pathloss value generated is 110.71 dB in LOS conditions, while in NLOS conditions the value is 140.42 dB. The 28 GHz working frequency has a slightly higher pathloss value than the 3.5 GHz frequency and has a difference in value of 18.99 dB for LOS conditions while in NLOS conditions it has a difference in value of 17.16 dB.

Abstract

Solar Power Plant is a plant that uses solar energy as a renewable source and converts solar energy into electrical energy. To maximize the intensity of sunlight, solar panels need an optimal tilt angle to receive high sunlight intensity. This research aims to determine the optimal tilt angle of solar panels and azimuthal angle so that solar panels obtain maximum output energy. The type of solar panel used is the monocrystalline type with an installed power of 1.51 MW with a total of 2800 panels using a nominal panel power of 540 Wp and 12 units of 1.1 kW inverters. At the research location, Tanjungpura University Solar Power Plant with coordinates 0 °3'37.486" LU 109 °20'34.633" BT (-0.060410, 109.342969). With a simulation method using PVsyst software to determine the optimal tilt angle and solar radiation data on meteonorm 8.1 in PVsyst software. The results showed that the optimal panel tilt angle and azimuth angle in producing maximum output energy at Tanjungpura University Solar Power Plant is at a panel angle of 5 ° with the azimuth angle facing northeast (-45 °) with an output energy of 2365 MWh/year, specific production of 1564 kWh/kW/year, and normalized production of 4.29 kWh/kWp/day.

Abstract

The development of wireless network technology, particularly WiFi 6 at 5GHz, offers greater reliability and data transfer capacity. Antenna design is a crucial aspect in optimizing WiFi 6 networks in complex wireless environments. The study examined a rectangular patch 2x2 MIMO Antenna for WiFi 6 at 5GHz with a focus on improving network parameters such as return loss, bandwidth, VSWR, and gain. The use of various methods and references from Balanis (2005) and Webster (2021) supports the development of antenna technology, while previous research by Ni Putu Kartika Dewi (2019) strengthens the understanding of microstrip antennas for LTE applications. The main objectives of the study were to design and simulate a rectangular patch 2x2 MIMO Antenna for WiFi 6, as well as analyze simulation data using CST Studio Suite 2019 software. This research uses hardware in the form of Acer Aspire laptops and CST Studio Suite 2019 as simulation software and antenna design. The simulation results show that this antenna is able to work in the frequency range of 4.5-5.2 GHz with a bandwidth of 55.4 MHz and return loss of -20.677981 dB, VSWR 1.2038357, and gain 3.429 dBi with omnidirectional radiation patterns. However, the addition of antenna patches has an impact on decreasing gain. This study provides an in-depth understanding of MIMO antenna design to support WiFi 6 performance in complex wireless environments.

Abstract

The development of electricity at Tanjungpura University, especially in the Faculty of Engineering, is very rapid in line with the development of new buildings and facilities in the campus environment which require a large electricity supply. The increasing use of electrical energy on the user side results in inappropriate loading. If this situation persists for a long time it will result in overload. For this reason, the researchers planned a centralized transformer based on minimal voltage drops and ideal transformer loading which refers to SPLN 72.1987. Determining the optimal location of this transformer uses literature study methods, field observations and descriptive analytics. In determining the location of a centralized transformer, several calculations are carried out, namely full load current calculation, distribution transformer loading calculation, manual voltage drop calculation and voltage drop simulation, transformer capacity calculation, voltage drop analysis over network area, voltage drop condition over network area, transformer layout calculation. , and calculate the type of cable to be used. By carrying out this study to determine the optimal location of the transformer, based on calculations and analysis, it can be determined that the ideal transformer capacity is 3000 kVA (3000000 VA), the loading results are 19,7%, the voltage drop is 0.44%, and the cable cross-sectional area is 150 mm2.
