Abstract

Inverter is an electronic circuit that convert electric voltage with direct current (DC) to alternating current (AC). One of the commonly used inverter configuration is H-Bridge circuit. Inverter with H-Bridge circuit does not need voltage-balanced diode or capacitor to operate and can be cascaded to obtain multilevel output voltage. H-Bridge circuit works by adjusting the combination of switches that were enabled. One of the commonly used switches is Metal Oxide Semiconductor Field Effect Transistor (MOSFET). The advantages of MOSFET as switching components are its fast switching speed and it did not cause current tail. Therefore, the writing of this paper aims to design a 12V DC to 220V AC 50Hz single-phase inverter with H-Bridge MOSFET circuit. The design stage begins with determining the specifications of the inverter, creating a block diagram of the inverter, determining the required components, and calculating the required parameters of the inverter. The designed inverter is simulated using Proteus 8.4 software. Simulation results are in accordance with the desired specification.

Abstract

 An environmentally friendly technological system that can be utilized as a food source is the aquaponic system. Aquaponics is a way of farming that combines aquaculture and hydroponics, the goal is to raise fish and plants in a circulated environment and interconnected system. The advantage of the aquaponic system is that fish waste can be used as a source of organic fertilizer that is good for plant growth and the products produced are organic products because they only use fertilizer from fish waste that has gone through a biological process. Aquaponics applies a natural ecological system in which there is a mutually beneficial relationship between fish and plants. The application of aquaponics on Cemara beach can improve the economy of the community and as one of the sources of attraction of this tourist spot.

Abstract

The development of automotive technology, especially in electric vehicles, is accelerating. Electric vehicles utilize batteries as the main power source, making batteries a very vital component. Batteries function to store energy, but can experience a discharge if used without recharging. Therefore, a battery charging system is needed to reduce the possibility of discharge. One charging method that can be applied is constant voltage, where the voltage is kept constant from the beginning to the end of the charging process. To keep the voltage constant, a rectifier circuit and buck converter are used. The rectifier circuit functions to convert alternating voltage (AC) into direct voltage (DC), while the buck converter reduces the direct voltage (DC) and maintains it constant with control to regulate the switching on the MOSFET. In this research, the system is designed with an input voltage of 220 V which produces a constant output of 12 V. Control using PID allows duty cycle settings to reduce the direct voltage (DC). In a hardware test using a VRLA battery load, the test results showed that after charging for 25 minutes, the battery voltage increased from 11.49 V to 11.65 V.

Abstract

The application of magnetic levitation that is currently developing is on land transportation in the form of maglev trains.Magnetic levitation is a system that uses an electromagnetic field to work against the force of gravity. The common point in application the magnetic levitation is used is the lack of contact and thus no friction this increases efficiency and system life. Magnetic levitation technology is still developing today. The magnetic levitation ball requires a good control method to maintain the ball's position on the mat against the earth's surface. This research implements Hybrid Proportional Integral Derivative (PID) control with fuzzy as a control system on magnetic levitation ball. The research for magnetic levitation ball uses Auto Tuning PID and Fuzzy–Takagi Sugeno controls. In the PID system, an auto-tuning system is carried out on simulink MATLAB R2019, and in fuzzy the function is designed to store input in the form of error (e) and delta error (de) while the function displays output in the form of effective height distance. Then defuzzification on fuzzy uses the Center of Area (COA) method. In magnetic levitation research, objects can experience ideal service conditions at a distance of 0.006 m from the end of the solenoid. in the transfer function test to reach a steady state, the risetime is 0.007817 s, the overshoot is 157.051%. then the PID tuning test to reach a steady state obtained a risetime of 0.214371 s, an overshoot of 0.460%. and in the fuzzy-PID hybrid test to reach steady state, the risetime is 0.044902 s and the overshoot is -0.357%.

Abstract

In some cases of Solar Power Generation System (PLTS) optimization, AI algorithms can be used to solve complex problems such as efficiency problems. In this research, a hybrid approach that combines Artificial Neural Network (ANN) and Particle Swarm Optimization (PSO) algorithms is used to optimize the Maximum Power Point Tracking (MPPT) system for solar panels. The hybrid technique seeks to maximize power output by precisely determining the ideal voltage and current points, which will increase the efficiency of solar panels. This study includes the measurement of parameters such as current (I), voltage (V), and power (W) in the MPPT system. The research shows that the hybrid ANN-PSO approach performs better than the traditional ANN method, producing mean squared error (MSE) and root mean squared error (RMSE) values that are lower. Moreover, research results show that the hybrid system maintains a load efficiency of approximately 51% in real-world measurements and about 67% in simulation data, indicating better performance and implementation ease.

Abstract

The Helical Type H-rotor turbine is a modification of the Darrieus turbine by Alexander Gorlov to improve the design of the H-Darrieus so the turbine can self-starting in low wind speed conditions. The purpose of this study is to analyze the pitch angle (5°, 0°, and -5°) when using the symmetrical airfoil (NACA 0018) on the performance of coefficient of power (CP), tip speed ratio (TSR) and coefficient of torque (CT) produced by Helical Type H-rotor turbine. The method used in this research is experimental investigation using wind tunnel.  The Helical Type H-rotor wind turbine is subjected to wind speed of 6 m/s. The results obtained show that the use of 0° pitch angle produces better CP, TSR and CT values than other pitch angles due to the angle of attack produced. this is due to the 0° pitch angle produces an angle of attack that is able to make a more optimal lift force on the turbine blade. At 0° pitch angle the CP value is 0.0337, TSR value is 1.5073 and CT value is 0.0224. While wind turbine that use -5° pitch angle produce better performance than wind turbine that use 5° pitch angle. However, the performance value of both (-5° and 5° pitch angle) is still below the wind turbine with 0° pitch angle.

Abstract

Lithium-ion (Li-ion) batteries are one of the most widely used energy storage technologies due to their advantages in high energy density, fast rechargeability, and efficiency. However, behind these advantages lie the weaknesses of lithium-ion batteries, namely that their performance and lifespan are greatly influenced by factors such as C-rate and lithium-ion battery temperature. A high C-rate can increase temperature and accelerate battery degradation, while a low C-rate tends to result in lower temperatures and more optimal capacity. This study aims to design an Internet of Things (IoT)-based State of Charge (SoC) monitoring system capable of real-time battery condition monitoring. The system uses an ESP32 microcontroller connected to a voltage sensor, an ACS712 current sensor, and an LM35 temperature sensor. The collected data is sent to Firebase and displayed through an Android application based on MIT App Inventor. The study focused on discharge cycles with varying C-rates: 1C, C/2, C/5, C/10, and C/20. SoC estimation was performed using the coulomb counting method. The results showed that as the C-rate decreases, the obtained capacity tends to increase, even exceeding the nominal capacity at C/20. Accuracy evaluation using RMSE yielded error values ranging from 0.12% to 4.04%. This system can serve as an effective solution for IoT-based battery monitoring
