Abstract

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.

Abstract

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.

Abstract

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.

Abstract

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.

Abstract

This study aims to optimize the performance of the distribution substation in maintaining the stability of the electricity network, especially in reducing the effects of voltage drops in the Kuta-cane Customer Service Unit (ULP). Significant voltage drops can affect the quality of electricity supply and cause instability that impacts the performance of customers' electrical equipment. This study includes data collection on distribution substations and network conditions, voltage drop measurements at critical points in the network, and voltage distribution simulations using electrical analysis software. Based on the results of the analysis, optimization of the distribution substation was carried out by adjusting the transformer capacity, installing load balancing devices, and rearranging the load distribution to reduce voltage drops. The optimization results showed an increase in voltage stability in the Kuta-cane ULP electricity network, as indicated by a decrease in voltage drops in previously problematic areas. This optimization has proven effective in maintaining distribution stability and improving the quality of electricity supply to customers. This study produces technical recommendations that can be implemented by the Kutacane ULP in maintaining the performance of distribution substations sustainably, so as to improve the reliability of the electricity network in the region.

Abstract

After the Covid pandemic, ecotourism is a tourism concept that prioritizes environmental sustainability and wise use of natural resources. One important aspect in ecotourism development is the use of renewable energy, such as solar panels, to meet energy needs without damaging the environment. This research aims to analyze the potential for renewable energy that can be produced by solar panels to support ecotourism development planning. This research includes collecting secondary data from relevant literature, measuring the intensity of sunlight at selected locations, as well as computer simulations to predict the energy output of solar panels. The analysis is carried out by considering factors such as weather conditions, orientation and tilt angle of the solar panels, and energy conversion efficiency. Please note: The research results show that the potential for renewable energy from solar panels in the selected locations is very significant. With optimal sunlight intensity and proper panel angle adjustment, ecotourism can produce most of its energy needs from this renewable energy source. The use of solar panels also has a positive impact in reducing carbon footprints and long-term operational costs. and the integration of solar panels in ecotourism development planning is a strategic step that can increase sustainability and energy efficiency. Recommendations from this research include wider implementation of solar panel technology, increased education about the benefits of renewable energy, as well as supporting policies from the government to encourage the adoption of green energy in the tourism sector.

Abstract

There are several things that happen when customers use electricity with prepaid Kwh meters. One of the problems now is an error in the Kwh meter or commonly called Kwh tempering. This study uses an observation method by taking a sample of 2 houses that have tempering problems in their Kwh. The results of the study of the first house with 900 VA electricity power found a current leak of 0.3 A, and in the second house with 1300 VA electricity power found a grounding cable connected to the neutral cable which caused a limping load of 0.85 A.
