Electricity is a fundamental source of energy that supports daily human activities across residential, commercial, and industrial sectors. As urban development and population growth continue in cities like Binjai, the demand for electricity is steadily increasing. Efficient management of electrical energy usage is crucial to ensure sustainability, reduce environmental impact, and maintain cost-effective energy supply systems. This study aims to analyze the level of electric power usage and the total duration of electricity consumption across various consumer categories in Binjai City. A descriptive quantitative approach is applied by collecting data from utility consumption records, calculating average power usage (kW), total energy consumed (kWh), and determining usage intensity based on national standards. The results indicate that household consumption accounts for the highest usage time, while industrial consumers exhibit the highest average power demand. Several households fall into the high Energy Consumption Intensity (ECI) category, suggesting potential energy inefficiencies. The study emphasizes the importance of awareness, consumption monitoring, and load management strategies to promote energy savings. The findings of this research can be used by local authorities and energy providers to improve electricity distribution planning, encourage responsible usage behavior, and support the development of sustainable urban energy systems.

In power generation, voltage stability is a very important thing to consider because it can affect the electrical system. Changes in the output voltage of a generator are influenced by various factors including dynamic load and magnetic amplifier voltage (excitation voltage). In this final project, a 3-phase synchronous generator excitation voltage control system is created to maintain the stability of the generator voltage according to its rating of 380 volts. By implementing a PID controller, the size of the excitation voltage can be adjusted by changing the duty cycle of the PWM for switching the IGBT in the DC-DC converter power circuit of the buck-boost converter type. With the PID controller parameters Kp = 3, Ki-0.001, Kd = 0.001 and the excitation voltage that can be provided by the power circuit up to 130 volts dc, the system can be stable when there is a change in load. The recovery time to reach steady state is 1.3 seconds when loaded and 1.1 seconds when the load is removed.

The problem of limited energy and high household electricity consumption in Indonesia encourages the importance of implementing energy-efficient lighting technology. The still high use of energy-wasting incandescent lamps indicates the low energy literacy of the community in choosing efficient types of lamps. This study aims to analyze and compare the energy efficiency of three generations of lamp technology, namely incandescent lamps, compact fluorescent lamps (CFLs), and LED lamps, with an experimental approach. Testing was carried out using a wattmeter, lux meter, and infrared thermometer in a closed room with controlled conditions. Each type of lamp was tested with a light output equivalent to ±800 lumens. The test results showed that LED lamps had the lowest power consumption of 10 watts with the highest efficiency of 80 lumens per watt and a surface temperature of 45°C. CFLs have a power consumption of 15 watts with an efficiency of 53.3 lumens per watt and a temperature of 70°C. Meanwhile, incandescent lamps consume 60 watts with an efficiency of only 13.3 lumens per watt and a surface temperature of 120°C. Simulation of household use shows that the use of LEDs can save electricity costs of up to 112,500 rupiah per month compared to incandescent lamps. The results of this study provide empirical evidence that LEDs are the most efficient lighting solution in terms of energy, cost, and safety of use for the household sector.

The need for stable electricity supply is a major challenge for Micro, Small, and Medium Enterprises (MSMEs), especially when disruptions occur in the main grid. This study examines the utilization of a small-scale Solar Power Generation System (PLTS) as a backup energy source to operate a donut mixer machine at CV Youlanda. The system consists of two solar panels with a combined power of 40 Wp, two 12V 8Ah batteries, a 1000W inverter, and a 20A charge controller (SCC). The research was conducted through direct field measurements to assess the performance and efficiency of the system under varying weather conditions. The observations show that in sunny weather, the system can generate about 200 Wh per day, which is sufficient to run two cycles of the mixer. The actual energy consumption per cycle was measured at 65.61 Wh. The total system efficiency was 2.63%, including panel efficiency of 8%, battery storage efficiency of 77%, and load efficiency of 42.71%. However, in cloudy weather, the available energy is only enough for about 8 minutes of operation. These findings indicate that, despite its limitations, small-scale PLTS remains a viable alternative energy solution that is cost-effective, environmentally friendly, and suitable for light operational needs in the MSME sector.

Disruptions in the electricity distribution network are one of the main problems that can reduce the reliability of electricity supply to customers. PT PLN ULP Balige as a customer service unit has the responsibility to ensure the continuity and quality of electricity distribution services in its operational area. This study aims to analyze the main causes of electricity distribution network disruptions using the Fault Tree Analysis (FTA) method. This method is used to identify the root causes of disruptions with a deductive approach arranged in the form of a fault tree. The data used in this study were obtained from disruption reports over the past year that occurred in the medium and low voltage distribution network at PT PLN ULP Balige. The results of the analysis indicate that several dominant factors causing disruptions include equipment component damage (such as transformers and cables), weather disturbances, and other external factors. With FTA modeling, logical relationships between causes can be systematically mapped, thereby facilitating the evaluation process and technical decision-making. This study is expected to be a basis for PT PLN ULP Balige in formulating prevention strategies and improving the reliability of the electricity distribution system through a more structured analytical approach.

Low grounding resistance is an important factor in ensuring the safety and reliability of electric power systems, especially on High Voltage Overhead Lines (SUTT). This study aims to analyze and improve the grounding resistance values on 150 kV SUTT towers on the Glang–Namorambe line using the three-point measurement method. Measurements were conducted to determine the actual condition of the grounding system and evaluate the effectiveness of the improvements made. Initial measurements showed that several towers had resistance values exceeding the maximum PLN standard limit of 10 ohms. To address this, improvements were made by installing additional electrodes, adding conductors, and using ground enhancement materials. After the improvements, remeasurements were conducted for each tower. The analysis results showed that the applied improvement method succeeded in reducing the grounding resistance value significantly, with an average reduction of 40–60%. The final resistance values of all towers were below the specified threshold, so that the grounding system can function properly in protecting equipment and personnel safety from overvoltage disturbances caused by lightning and ground faults.
