Abstract

Lithium-ion (Li-ion) batteries are one of the battery technologies widely used in electric motorcycles (EVs) because they have high efficiency and good durability. This battery functions as the main energy source for electric vehicles and is an important component in supporting vehicle performance. This study aims to analyze the characteristics of Lithium-ion batteries in electric motorcycles by considering factors such as operating temperature, voltage, and the influence of speed and terrain. Tests were carried out on flat and uphill tracks with speed variations of 10 km/h, 30 km/h, and 50 km/h. The results showed that Lithium-ion batteries tend to experience a faster increase in temperature when used at high speeds, but the battery voltage remains stable during the Discharge and Charging process without any significant spikes. These findings provide insight into the performance of Lithium-ion batteries in electric vehicles, as well as the importance of temperature management to maintain optimal battery performance.

Abstract

Voltage transformers are one of the important components in an electric power system that functions to reduce the voltage from the transmission network to a lower level for measurement and protection purposes. The quality of the insulation of the voltage transformer greatly affects the reliability of the operation of the electric power system. Therefore, periodic insulation resistance testing is needed to ensure optimal insulation performance and avoid electrical interference. This study aims to analyze the results of the insulation resistance test on the voltage transformer used in the Bay Banda Aceh 1 and Bay Banda Aceh 2 conductors at the Ulee Kareng Substation. The test was carried out using a megger test tool with a method of measuring the insulation resistance between the primary winding and the ground and between the primary winding and the secondary. The measurement data were compared with applicable standards to determine the insulation condition of the voltage transformer. The results of the study showed that the insulation resistance values ​​obtained from both conductors had variations that were influenced by environmental factors such as temperature and humidity. Based on the analysis carried out, most of the test results were still within safe limits according to IEEE and SPLN standards. However, there were several test values ​​that were close to the minimum limit, which indicated insulation degradation that needed further attention. With this research, it is expected to provide information on the condition of voltage transformer insulation and recommendations for preventive actions needed to maintain the reliability of the electric power system at the Ulee Kareng Substation.

Abstract

Three-phase motors are one of the main equipment in the electric power system used to drive various industrial machines, including the Blang Pidie Substation. One of the problems that often occurs in three-phase motors is the loss of voltage in one phase (single phasing), which can cause current imbalance, motor temperature increase, and the potential for greater damage. Therefore, a protection system is needed that can detect the loss of single-phase voltage and automatically stop motor operation to prevent further damage. This study aims to design and build a single-phase voltage loss protection relay system on three-phase motors at the Blang Pidie Substation. This system uses a voltage relay as the main component to detect voltage loss in one phase, which will then activate the current breaking mechanism to protect the motor. Testing is carried out by simulating various voltage loss conditions to analyze the response speed and effectiveness of the relay system in protecting the motor. The results of the study show that the designed relay system is able to detect single-phase voltage loss with high accuracy and fast response time. When a disturbance occurs, the system immediately cuts off the electricity to the motor to prevent overheating and permanent damage. The implementation of this system is expected to improve the reliability of three-phase motor operations and reduce the risk of failure at the Blang Pidie Substation.

Abstract

Indoor air quality is an important factor affecting human health and safety, especially in industrial and laboratory environments that are at risk of hazardous gas leaks. To overcome this problem, a system is needed that is able to monitor air quality in real time and detect gas leaks with a high level of accuracy. One of the artificial intelligence methods that can be used in air quality control systems is fuzzy logic, which is able to process sensor data with a high level of uncertainty and produce optimal decisions.This study aims to design and develop an air quality control system with fuzzy logic-based gas leak detection. This system uses various sensors, such as gas sensors (MQ-series), temperature sensors, and humidity sensors, whose data is processed using a fuzzy algorithm to determine the level of air quality and detect gas leaks automatically. If a gas leak or a decrease in air quality is detected below the set threshold, the system will activate a warning alarm and control ventilation to maintain safe air conditions.The test results show that the developed system is able to detect gas leaks with a high level of accuracy and provide a quick response to changes in indoor air conditions. The use of fuzzy logic allows the system to adjust actions based on the severity of the leak or air pollution, thereby increasing efficiency and reliability in air quality control. Thus, this system can be an effective solution in improving indoor safety and comfort, especially in environments that are vulnerable to gas leaks.

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

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.

Abstract

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.
