Abstract

Public street lighting (PJU) is a public lighting installation and is usually installed on roads, bridges and certain places, such as parks and other public places. Public Street Lighting Lamps (LPJU) are lamps used to illuminate roads at night to make it easier for pedestrians, cyclists and vehicle drivers to see more clearly the road/terrain that will be traversed at night, thereby increasing traffic safety and user comfort. roads and provide security from criminal activities. On the highways in Sungai Betung, Bengkayang and Ledo sub-districts in Bengkayang Regency, in the existing condition, 84 PJUs are installed with single ornament light points, the lights used are 150 watt SON-T with an illumination of 15.67 lux, and 60 watt LEDs with an illumination of 7 .69 lux, with a road width of 4-5 and a distance between poles of 45-50 meters requires energy of 109.08 kWh/day.

Abstract

Continuing water flow rates over time can lead to sedimentation and erosion at the base of the river, potentially damaging ecosystems and infrastructure around the rivers. Monitoring of water flow speeds below the surface of a river needs to be done for monitoring in order to analyze the speed of the water flow that is in the surrounding river. The study develops a monitoring device for water flow speed under the surface using Modbus RS485 communications that are integrated with Internet of Things (IoT) technology to provide water flow information. The research method involves the use of water flow sensors and NodeMCU ESP32. The water flow sensor is capable of accumulating data with measurement accuracy of 96.92% with comparison of a digital flow meter. Tests in the pool are carried out with valve adjustments of 10% to 90% at depths of 15 cm and 45 cm. The pulse generated by the water flow sensor is seen using the Instrustar oscilloscope with the help of the Multi VirAnalyzer application. The test results showed that current speeds range from 0.05 m/s to 0.36 m/s, with pulses increasing as the flow rate increases. As for testing in rivers, sensors can measure current speed up to a depth of 60 cm, with an average speed of 0.06 m/s at a dependency of 15 cm to 0.27 m/s at 60 cm. Test results show that the more in the sensor placement, the higher the measured current speed. The data is displayed on the LCD and Blynk platform, as well as stored in the micro SD.

Abstract

This research discusses a comparative analysis of Cold Rolled Grain Oriented (CRGO) material as the core of a 3-phase 200 kVA distribution transformer using Ansys Maxwell software. CRGO material has several grades, namely M-3, M-4, M-5, and M-6, which differ in lamination thickness and core loss characteristics. The study aims to analyze and compare the flux density and core losses of the transformer with each CRGO grade. Simulations were conducted using Ansys Maxwell to compare flux density and losses for each CRGO grade to determine the most efficient material for use as a transformer core. The simulation results show that flux density increases over time across all tested CRGO grades, with grade M-3 exhibiting the highest flux density, followed by M-4, M-5, and the lowest being M-6. The simulation results for core losses are as follows: 226.2172 W for grade M-3, 242.1566 W for grade M-4, 259.2061 W for grade M-5, and 298.1239 W for grade M-6. Hysteresis and eddy current losses tend to be lower in lower-grade CRGO (M-3) compared to higher-grade CRGO (M-4, M-5, and M-6) due to the smaller lamination thickness in lower grades and larger lamination thickness in higher grades.

Abstract

Electricity is a very important need and the most important economic resource for humans. One of the important factors in fulfilling electrical safety is the installation of electrical installations that meet the provisions and standards regulated in the 2020 General Requirements for Electrical Installations (PUIL) as a reference for installing electrical installations. This is the problem of this research, namely the level of feasibility of electrical installations and the causal factors. inadequacy of electrical installation. This research aims to determine the percentage of feasibility of electrical installations and determine the causes of unfeasible electrical installations. The method used is descriptive analytic. The sample in this study was Temuyuk Village, Bunut Hulu District with a power limitation of 450 VA -900 VA for 79 houses. The sampling technique uses proportional random sampling technique. Data collection techniques use observation, interviews and documentation. In this research, there are five references for feasibility parameters, namely: feasibility of equipment, feasibility of conducting cables, feasibility of installation safety (MCB), feasibility of input voltage and feasibility of insulation resistance. The results of the percentage of feasibility of electrical installations for households in Temuyuk Village, Bunut Hulu District over the age of 15 years were 77.22% feasible (amounting to 61 houses) and 22.78% not feasible (amounting to 18 houses).

Abstract

Solar Power Plants (PLTS) are one of the environmentally friendly energy sources that utilize sunlight which at the same time reduces dependence on PLN energy which is not only expensive but also often harms the environment. Although building a solar power plant requires a large investment cost, technical planning such as the location of solar panels, system capacity and integrity to the existing power grid are important to consider. This solar power plant was built on the roof of the school's main building. This solar power plant was built using monocrystalline solar panels with a capacity of 670 Wp as many as 14 units, inverter with a capacity of 5000 Watts as many as 2 units, solar charge controller as many as 1 unit and batteries with a capacity of 400 Ah as many as 15 units. This solar power plant is planned to operate for 25 years with 9,306 Wp of energy generated.

Abstract

The Tanjungpura University Hospital building is located in the city of Pontianak, which is situated on the equator and often faces the potential of lightning strikes, thus requiring the installation of an external lightning surge protection system. This study aims to design an external lightning surge protection system capable of protecting the Tanjungpura University Hospital building using the rolling sphere method. In the rolling sphere method, calculations will be made for the lightning strike distance (R), protection radius (Rp), protection area (Ax), and determination of protection angle (α). The University Tanjungpura Hospital building is at protection level IV, with a current strength of I = 16 kA and a lightning strike distance to the ground of 60.63 meters. The results obtained for using finials with the same height, hp = 1 meter, require hundreds of finials, while using a combination of finials and towers requires 68 finials. In the case of tower finials with a height hp = 10 meters, additional conductor wires are added or the catenary method is used with 14 conductor wires connecting 28 tower finials with a height of 10 meters, due to the areas outside the protection zone between these 28 final towers, necessitating the addition of conductor wires to expand the protection area of the rolling sphere method to protect the areas of the Tanjungpura University Hospital building.

Abstract

The Hajj Dormitory Building in Pontianak City is a new four-story facility designed as a transit hub for Hajj pilgrims in West Kalimantan. This study aims to design a safe, reliable, and standard-compliant electrical installation to support the building's operations. The planning process is based on SNI 03-6197-2020 for lighting installations and PUIL 2020 for cable sizing, protective devices, and voltage drop requirements. The methods used include manual calculations for power requirements, voltage drop simulations using ETAP 21, and electrical installation design using AutoCAD software. The results indicate that the building requires a total power of 310,151 VA. The installation utilizes 2x(4x150 mm ²) cables and a Circuit Breaker (CB) with a 630A rating. A 400 kVA generator set is needed to provide backup power. Voltage drop simulations using ETAP 21 show a value of 0.163% from PLN to the Main Distribution Panel (MDP), which is within the maximum limit set by PUIL 2020 (≤ 4%). This electrical installation plan ensures that the electrical system of the Hajj Dormitory Building operates efficiently and meets safety and reliability standards. The findings of this study can serve as a reference for implementing the building"™s electrical installation.
