Abstract

This study examines the efficiency of electric power in BLDC motors as electric motorcycle drivers with various load and speed experiments. Electric motorcycles are one of the vehicles that are in great demand by the public. BLDC motors are the main drivers of electric motorcycles where motor capacity planning includes motor power and torque which greatly affect the acceleration and speed of the motorcycle. Motor capacity planning is obtained by calculating the total weight, the location of the motor's center of gravity, the desired acceleration, tire rolling resistance to asphalt, air resistance and road slope angle. From the calculations and analyses that have been carried out, the required motor power is 2.5 kW. Testing the motor's ability to carry loads is carried out by providing variations in passenger and goods loads of 58 kg, 98 kg and 135 kg, and driven with a target speed of 10 km / h, 20 km / h and 30 km / h.

Abstract

Solar energy is a renewable energy source (EBT) that will not run out. One of the uses of solar energy is as a source of energy for solar-powered public street lighting (PJUTS). Public street lightingCampus Area of Panca Budi Development Universityaims to help improve road safety at night. In this study, planning will be carried out for solar-powered Public Street Lighting (PJUTS) located inCampus Area of Pancasila Development Universitywith a road width of 5 m and a road length of 320 m. Planning for solar-powered public street lighting (PJUTS) requires 14 lighting points with a load of 24 Watt LED lights. With a pole height of 7 m and a distance between poles of 25 m, the lighting intensity is 6.72 lux for manual calculations. Meanwhile, according to applicable standards, the lighting intensity value is 3-7 lux. The solar module used has a capacity of 75 Wp. PJUTS operates 12 hours a day and is able to continue operating for 3 days without a solar energy source. The total cost that must be incurred for this solar-powered public street lighting is IDR 1,224,500,000

Abstract

This study focuses on determining the capacity of the solar power plant (PLTS) components used as an energy source at a public electric vehicle charging station (SPKLU) to charge the batteries of electric cars at Universitas Pembangunan Panca Budi Medan. Calculations are carried out to obtain the area of the solar module, the power required, the number of solar panels, the SCC capacity, the backup battery, and the charging time of the electric vehicle. The research method used is a research method with an approach calculation by comparing several similar references related to planning in building a PLTS. The battery data collection method is carried out by observation, literature study and collection of weather condition data through the BMKG of Medan City. The results of the study show that with a solar intensity of Gav 4.42 kWh/m2/day, a module array area of 42,071 m2 is required. With a sunlight intensity of 1000 W/m2, the power generated by the area is 6,731 Wp. By using a 120 WP solar module, the number of panels used is 60 units consisting of 15 strings of 4 units in each string. The system can produce 8,333 Wp, 71 V 103 A of power. The SCC produces 128.73 A. The charging time required is 8.63 hours or 8 hours 37 minutes.

Abstract

Insulation resistance testing is an important part of electrical installation system maintenance to ensure system safety and reliability. This study aims to analyze the condition of low-voltage cable insulation in the PT. PLN (Persero) UPP Sumbagut 1 building through insulation resistance testing using a megger. Measurements were conducted at several distribution panel points by comparing the results with the 2011 PUIL standard. The test results showed a decrease in insulation quality at several points, especially in the generator panel area, which has the potential to cause disruption to the power distribution system. The decrease in insulation resistance can be influenced by various factors such as cable age, environmental humidity, and installation conditions. This study provides recommendations for preventive measures in the form of cable replacement at critical points and the implementation of periodic testing to maintain the performance of the electrical system. In addition, evaluation of installation design and environmental control is also needed to increase cable service life and overall system efficiency.
