Public Street Lighting (PJU) is a means used to improve the function of the road so that it can illuminate the road at night, improve safety, security, traffic comfort and make road users more comfortable in the campus environment. PJU lights in the Tanjungpura University environment already exist on Jalan Prof. Dr. H. Hadari Nawawi, especially around Tanjungpura University Currently, these lights use 250 watt SON lamps with a pole height of ± 9m and produce an average light intensity of 2188.38 cd with a light intensity of 16.69 lux. The average energy consumption per day is ± 170 kW, but the lighting intensity is not in accordance with SNI standards. The recommended improvement effort is to replace them with 120 watt LED lamps, which can meet SNI standards for secondary collector road classes with an illumination intensity of 3-7 lux. Evaluation and recommendations are needed to improve lighting conditions in the neighborhood. After being replaced with 120 watt LED lights, the average pole height is ± 9m, the light intensity is 954.52 cd, and the illumination intensity is 7,28 lux, the results meet the SNI standards for secondary collector road classes. Although the monthly electrical energy consumption reaches Rp.4,721,640, LED lights produce a clearer contrast of light on objects, although the intensity is lower than SON lamps which have a greater intensity, but the color and contrast on objects become clearer

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.

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.

Wind power plants are a type of power plant that uses wind energy as the main source to produce electrical energy. This research analyzes the effect of wind power generation on voltage and power losses under light load, peak load, and average load conditions in the distribution system. The data that will be used is 33 bus distribution system data and distribution system network data. Then thoroughly calculate the voltage and power losses of the distribution system using MATLAB software version R2016A. This research obtained the results that the lowest voltage in the 33 bus distribution system occurred on bus 18, so that bus would be connected to the PLTB. As the mechanical power of the turbine increases, the system voltage profile for various load conditions improves. In the distribution system, before the PLTB was connected, the best voltage profile at light load was 0.9378 pu and the worst voltage profile at peak load was 0.8671 pu. After the system is connected to the PLTB, the light load becomes 0.9466 pu, the peak load becomes 0.8771 pu, and the average load becomes 0.9131 pu. By connecting the system with PLTB, power losses at light loads are reduced to 184.8918 kW (Pm = 2.0200 pu), peak loads are reduced to 807.7297 kW (Pm = 3.6880 pu), and average loads - the average decreases to 437.8619 kW (Pm = 2.7709 pu).

LoRa is a long-range communication technology with the advantage of wide coverage but faces challenges in single-hop communication. This issue arises because the communication occurs in Non-Line of Sight (NLOS) conditions. The method used to address this is by testing a multi-hop LoRa communication system, where relays act as intermediaries between the transmitter and the gateway. The results from this study show that communication between the transmitter and relay 1 maintains a consistent RSSI of -94 dBm with an SNR ranging from 8.25 dB to 10 dB. Communication between relay 1 and relay 2 has an RSSI ranging from -83 dBm to -86 dBm and an SNR between 7.50 dB and 9.50 dB. For communication between relay 2 and relay 3, RSSI ranges from -105 dBm to -116 dBm with an SNR between 3 dB and -8 dB. Communication between relay 3 and the gateway shows an RSSI between -94 dBm and -97 dBm with an SNR between 2.00 dB and 2.50 dB. The multi-hop LoRa system successfully detected and transmitted fire data in real-time, including smoke concentrations rising to 85 ppm, with smoke and fire indicators both showing a value of 1, indicating the presence of a fire, as well as changes in temperature and humidity. The system consistently detected and transmitted fire data accurately under various conditions, with sensor data from the transmitter reaching the gateway without loss or damage.

Power transformer is a vital equipment in the electric power system that plays an important role in distributing electrical energy from the generator to the load center. Transformers require a protection system that is able to detect an internal or external disturbance with a very fast time to prevent widespread blackouts. Transformer protection generally uses differential relays that require settings in determining their working parameters. On this basis, the authors conducted a study of the Siemens 7UT86 percentage differential relay as a 60 MVA power transformer protection at the 150 kV Dayeuh Kolot GIS, by taking data to perform mathematical calculations to obtain working parameters and testing. The results of mathematical calculations obtained the rating current value used to select the ratio of installed CT to differential current. The relay is set using slope 1 of 30% and slope 2 of 80% and a differential current of 0.3 I/IrObj to prevent unnecessary blackouts due to the appearance of differential currents by magnetizing currents, inrush, tap changers, CT saturation and as a safety factor. Tests using Omicron test equipment obtained results in the form of actual differential current values of both slope areas, angular stability, current and angular ramping and relay operation delay times. Testing the working parameters of the relay obtained the result that the relay works by commanding the circuit breaker to trip when it exceeds the pick up value. During internal faults and at faults below the pick up value and during external faults the relay standsby.

Battery charging is the process of charging a battery from low to full capacity. In this study, the battery used is an 18650 48V 21Ah lithium-ion battery that is charged using an 18650-lithium charger that has an auto cut off feature when the battery is full. This feature is important to prevent overcharging and overcurrent, which can damage the battery. However, this charger is not equipped with a temperature sensor and cannot display voltage and current values. Monitoring the temperature, voltage, and current is very important, especially since battery temperatures exceeding 60 °C can cause damage and risk fire. Charging the battery to 80-90% of full capacity can also extend battery life by reducing chemical degradation. The system developed in this research includes an auto cut off feature that is activated based on temperature, a voltage regulated between 47.1V to 53.5V, and control via IoT Blynk. The system uses ESP-32 as the microcontroller, MAX6675 thermocouple temperature sensor, PZEM-017 sensor for DC voltage and current, and 16x2 LCD keypad shield to set the set point and display the sensor results. The results show that auto cut off works well, with voltage sensor accuracy reaching 99.85% and PZEM-017 sensor accuracy of 97.68%.
