Abstract

Currently, the use of energy sources as fuel for power plants still heavily relies on fossil fuels or, in other words, non-renewable energy sources that will gradually deplete and undoubtedly have environmental consequences. This research is conducted in an area that is geographically distant from the PLN (State Electricity Company) grid. Recognizing the need for increased use of Renewable Energy (EBT) and in line with the national target for 2025 set by the Ministry of Energy and Mineral Resources (ESDM), it is expected that the use of EBT can reach 23%. One of the efforts in developing EBT in areas that are not covered by the PLN electricity network is through Solar Power Plants (PLTS). The objectives of the upcoming research include calculating the cost per kilowatt (kW), determining the investment cost for the planned PLTS, and assessing the PLTS capacity to meet the energy demand in Dusun Molo, Bengkayang Regency. Based on the calculation results, the estimated daily electricity demand in Dusun Molo, Seren Selimbau Village, supplied by the PLTS, is 224,223 kWh/day. The power generated by the PLTS to meet the needs of Dusun Molo is 53,283 Wattpeak, while the planned power generation by the PLTS to meet Dusun Molo's requirements is 76,000 Wattpeak. The investment cost for the construction of the PLTS in Dusun Molo is IDR 3,213,751,000, including an 11% Value Added Tax (VAT). After the calculations, the Cost of Energy (COE) or price is determined to be IDR 2,972.00/kWh. This research provides an estimate of the investment cost for the construction of a PLTS in Dusun Molo, Bengkayang Regency.

Abstract

The 7 In 1 Building at Tanjungpura University, located in Pontianak, along the equator, faces frequent lightning strike risks, necessitating the installation of a reliable external voltage protection system. This study aims to determine the configuration of a conventional protection system using the electrogeometry method, comparable in reliability to the Early Streamer Emission (ESE) protection system. Considering a lightning current of 16 kA and a lightning strike distance to the ground of 60,63 meters, the required number of conventional protection systems for optimal reliability is determined: the Library Building needs 104 rods, the Conference Building 62 rods, Joint Lecture Buildings A and B at Tanjungpura University 59 rods each, and the Integrated Laboratory Building 17 rods. The use of conventional voltage protection systems with the electrogeometry method has proven to achieve good reliability, equivalent to that of Early Streamer Emission (ESE), despite generating a smaller protection radius and requiring a higher number of finials.

Abstract

Internet availability must be sufficient to meet the needs of the era, supported by extensive coverage and robust network stability. Every provider competes in the current internet market, especially in Pontianak City. This research aims to analyze the Quality of Service (QoS) of the 4G LTE networks provided by three widely-used providers in the community. The research results indicate that the Quality of Service of the 4G LTE network in the Waterfront area of Pontianak City falls into the good category. Measurements in the afternoon show good quality, supported by the close proximity between the research location and the Base Transceiver Station (BTS) without interference. However, data transfer speed experiences a decline in some measurements, especially during cloudy weather and busy visitor periods, affecting network jitter parameters. In the evening measurements, despite obtaining fairly good values on some parameters, throughput still receives a poor rating. The decrease in quality in jitter parameters occurs on the first and second nights due to the density of visitors and excessive queuing in the network. The reasons for the poor quality of the cellular network include obstacles from tall buildings, longer transmission distances due to river expanses, and bad weather. Internet user density also affects signal strength. Furthermore, the distance between the BTS and devices plays a crucial role in network propagation, so an efficiently designed 4G network should provide even coverage and consistent quality.

Abstract

This study aims to evaluate the performance and capacity of the Solar Power Plant (PLTS) system that has been installed on charging batteries for street lighting. Before cleaning the surface of the solar panel, the energy produced only reached 707.46Wh, and after cleaning, the energy produced increased to 859.77Wh. However, these results still do not meet the daily energy requirements for a 12-hour battery charge. The research methodology includes analyzing the impact of dust on solar panels, evaluating the performance of PLTS, and calculating daily energy requirements. Based on the PLTS battery capacity of 9600Wh, the maximum energy obtained from charging the battery is still insufficient to power two street lighting lamps for 12 hours. Therefore, an evaluation of the installed PLTS was conducted, resulting in several findings. First, it is necessary to add 11 units of solar panels with a capacity of 455Wp so that the required energy can be met. Second, the capacity of the installed battery is sufficient to meet the energy needs of the lighting. Third, the capacity of the Solar Charge Controller (SCC) needs to be increased to 150Ampere due to the addition of solar panels. Finally, the inverter that has been installed with an output of 1000Watt is adequate for the needs of the system. The results of this evaluation can serve as a basis for improving the performance of the PLTS in order to meet the desired energy needs.

Abstract

First Person View (FPV) technology is used, where real-time video signals from drones are transmitted to ground stations, and provide a more realistic experience through FPV display through the monitor screen. This research focuses on designing and analyzing the performance of Cloverleaf and Helix antennas as FPV video receivers on Racing Drones with a frequency of 5,8 GHz which are capable of having a greater receiving power range from transmitters than the default antennas on FPV. The simulation results in CST Studio Suite 2019 show that the Cloverleaf antenna with a wire diameter of 1,5 mm and a bend angle of 105 ° has a VSWR value of 1.463, return loss of -14.508 dB and Gain of 10.74 dBi. While the Helix antenna diameter of 0,8 mm has a VSWR value of 1.081, return loss of -28.101 dB and Gain of 15.54 dBi. Testing on the monitor screen, both types of antennas have been successfully realized on the FPV video monitor screen and are able to capture real-time images from the transmitter on Drone Racing. The longest distance reached is 454 m for Cloverleaf antennas, 425 m for Helix antennas, and 374 m for Cloverleaf and Helix antennas combined. Cloverleaf and Helix antennas on monitors are better for near-medium ranges, but the signal decreases and can be lost at longer distances.
