Abstract

The rainy season is an obstacle for everyone, especially drying shoes, because rain can hinder the process of drying shoes. Currently, shoes are still dried using the conventional method, namely by utilizing the sun's heat. The next development is a system for drying shoes using gas fuel, but it has the potential for fire. In this final project, a shoe drying system is designed which is controlled using PI control according to a specified setpoint to dry shoes when exposed to rain or at night. To get the appropriate room temperature, the output voltage from the heater needs to be controlled using the Digital Firing Angle. The ignition angle is regulated by the Digital Firing Angle circuit. To maintain the temperature conditions in a stable condition, namely 65°C, this tool is controlled using PI (Proportional Integral) control. This dryer is designed for a maximum of 1 pair of wet shoes. With final humidity results in the drying room ≤ 20%RH. With this final project, it can dry shoes in rainy conditions in 94 minutes for synthetic leather shoes and 104 minutes for leather shoes.

Abstract

Ship transportation is the primary mode of trade and transportation at sea in the maritime industry. Initially, humans employed ships as a method of pursuing and capturing fish or animals in aquatic environments. As the ship era progresses, it actively engages in all aspects pertaining to ships. Presently, the ship is propelled by its engine, which is a significant improvement over its initial reliance on wood or oars. In addition to engines, propellers are employed to transform the rotational motion of the engine into propulsive force in the marine environment. Propellers are also present on aircraft, serving the same purpose but positioned at various locations in the air. A thruster is a hybrid device that combines an engine and a propeller. This sort of thruster is specifically designed for use on tiny boats or prototypes, for the purpose of simulating, exhibiting, or participating in contests. ESC is a component that facilitates the alteration of the input value to the intended velocity. In addition to their primary function of fulfilling food requirements, ships are presently employed in diverse capacities, including military vessels, tourist vessels, submarines, passenger ships, and more.

Abstract

ABSTRAKKetika charging, baterai lithium-ion seringkali terjadi overheat dan overcharge. Begitu pun ketika discharging juga terjadi overdischarge, overheat dan overcurrent apabila tidak sesuai kurva karakteristik (T=-8.75*I+60). Hal tersebut menyebabkan kerusakan sel baterai sehingga megurangi lifetime baterai. Penelitian ini dibuat sistem battery management system (BMS) yang memantau suhu dan arus melalui pembacaan sensor. Apabila suhu saat charging melebihi batas maksimum (45°C), sistem akan diproteksi dengan menonaktifkan MOSFET (switch). Proteksi ketika discharging terjadi jika suhu atau arus melebihi batas kurva atau safety factor (p). Dari hasil data charging, sistem mampu memproteksi overheat dengan error 0.43% dan menghitung nilai state of charge (SoC) dimana akan beralih ke mode discharge jika melebihi 85% dengan error 0.01%. Saat discharging sistem mampu memproteksi ketika besaran suhu dan atau arus melebihi safety factor yakni 60 dengan error 1.74% serta mampu beralih ke mode charge jika SoC kurang dari 40% dengan errror 0.018%.Kata kunci: Safety factor, Battery Management System, State of Charge ABSTRACTDuring charging, lithium-ion batteries risk overheating and overcharging, while discharging may lead to overdischarge, overheating, and overcurrent if deviating from the characteristic curve (T=-8.75*I+60), causing battery cell damage and reducing lifetime. This study introduces a Battery Management System (BMS) that monitors temperature and current using sensors. If the charging temperature surpasses the limit (45°C), the system protects by deactivating the MOSFET switch. Discharging protection triggers if temperature or current exceeds the curve or safety factor (p). Analyzing charging data, the system defends against overheating with a 0.43% error, calculates State of Charge (SoC), shifting to discharge mode if exceeding 85% with a 0.01% error. During discharging, the system safeguards against temperature and/or current surpassing the safety factor of 60 with a 1.74% error and switches to charge mode if SoC falls below 40% with a 0.18% error.Keywords: Safety factor, Battery Management System, State of Charge

Abstract

Utilization of electrical loads in predominantly inductive single-phase low-voltage power grids, the quality of electrical power becomes poor due to reactive power consumption resulting in a lack of power factor resulting in power loss, voltage drop, and decreased service life of the power grids. equipment. The research on reactive power compensation using TCR-FC aims to make improvements in improving the power factor in single-phase low-voltage electrical networks so that they have flexible control, do not experience excess compensation, have fast dynamic responses, and are space-saving. And can monitor voltage, current, and phase difference parameters through sensor readings to process data mathematically. When using electrical loads, the reactive power value is larger and the power factor is low below 0.85, the system controls the ignition angle of the TRIAC so that the current flowing into the reactor can be controlled by the reactive absorption measure of the fixed capacitor. So, it can improve the power factor. Simulation results can increase the power factor that exceeds the average value of 0.9 by 0.9797 with an error of 0.0288%. Hardware test results can increase the average power factor to exceed 0.9 by 0.9758 with an error of 0.1373%. in conclusion, reactive power compensation devices that use thyristor-controlled reactors and fixed capacitors can be more efficient than capacitor banks.

Abstract

The research discusses the implementation of a fast charging system on Lithium-Ion batteries by comparing the performance of conventional Buck Converters and Synchronous Buck Converters. Charging is carried out using constant current (CC) and constant voltage (CV) methods with set points of 4A and 16.8V as the targets used, and is equipped with sensors to monitor voltage and current during the charging process. The system is controlled by the Adaptive Neuro Fuzzy Inference System (ANFIS) which is useful for maintaining charging stability at one battery specification with a full capacity of 4.2V voltage and 4A current. Test results show that ANFIS is able to maintain filling parameters within safe limits. In addition, the Synchronous Buck Converter provides better efficiency than conventional Buck Converters in terms of efficiency and controlling voltage fluctuations, so it is more optimal for use in Lithium-Ion battery fast charging systems.
