Abstract

The source of energy used in everyday equipment is electrical energy. Starting from a small scale from household needs to a large scale as an energy source for industry, there are two types of voltage commonly used for various purposes, namely alternating voltage or also known as alternating current (AC) and direct voltage or direct current (DC). To get a DC voltage that is in accordance with the voltage standards required by the equipment, a voltage source is needed that can produce a voltage that varies the equipment is to use a converter then the output voltage needs to be controlled. Controlling the output voltage at the buck converter using the Mamdani fuzzy method. This control system is designed and implemented on the Arduino Mega 2560 platform which is programmed using Simulink Matlab. Mamdani fuzzy method is used to determine the duty cycle based on the rules in the rule base, which consists of five membership functions. The proposed system is tested and verified through experiments with an input voltage of 24 Volts and an output voltage varying from 6, 9 Volts to a maximum of 12 Volts. The experimental results show that the buck converter output voltage control system using Mamdani fuzzy successfully controls the buck converter output voltage according to the specified reference value. This can be seen from the resulting output voltage error, with a maximum of only 2 % when the reference voltage is at 12 Volts.

Abstract

The problem with 3-phase induction motors is that when starting the motor, the motor starting current can reach five to seven times the nominal current. This research compares slip, starting current, bus voltage, acceleration torque, motor torque, energy savings, and kVAR from the direct on-line (DOL), variable frequency drive (VFD), soft starting, and autotransformer starting methods in the electrical transient analyzer program (ETAP) software. This research result shows that the fastest VFD slip reaches a steady state, namely at 11+ seconds. The lowest starting/starting current is owned by the VFD method, namely <20% full load amps (FLA) in the first 2 seconds. The lowest decrease in bus voltage at steady state was experienced by the VFD method, namely 0.8152%. The quickest acceleration torque reaches a steady state in the VFD method, namely in 11+ seconds. The soft starting method owns the lowest starting torque, namely 20.75%. The soft starting method has the largest energy savings, namely 148.02 kW. Of the several variables observed, the best starting method is the VFD method.

Abstract

Various electrical equipment uses direct voltage (DC) as its power source, such as electronic equipment, dc motors and so on. Direct voltage (DC) used in electrical equipment usually consists of various voltage ratings ranging from 1.5 volts, 3 volts, 6 volts 12 volts and others. To get a direct voltage (DC) that suits the needs of the equipment, the direct voltage needs to be controlled. Direct voltage control is usually implemented using a power converter. In this research, the buck converter output voltage control based on Adaptive Neuro Fuzzy Inference System (ANFIS) will be implemented using Arduino Atmega 2560. The buck converter output voltage control system made in this research will be tested through experiments with an input voltage of 24 Volts and a maximum output of 18 Volts. The experimental results show that the ANFIS-based buck converter output voltage control system has been able to control the buck converter output voltage according to the desired reference voltage value.

Abstract

Clean water is one of the most vital needs for a mosque. Clean water is generally taken from wells using electric water pumps. The use of water pumps is often a problem in areas where the electricity network is often off, as happened in the Raya Mosque of Nagari Salareh Aia, Palembayan District, Agam Regency. To overcome this problem, a solar automatic water pump is designed which is equipped with a battery as a backup power supply and one phase inverter to convert the solar panel voltage to alternating voltage according to the voltage of the water pump motor. The water pump automation is designed using a floating switch installed in a water tank. This solar water pump is implemented using a 300 wp solar panel, a 90 Ah battery and a 1200 Watt inverter. This solar water pump is also equipped with a solar charger for charging and discharging batteries. Field test results show that the automatic solar water pump proposed in this service program has been working properly according to the plan.

Abstract

This study aims to determine the effectiveness of problem-based learning methods in electrical lighting installation subjects at SMK Negeri 1 West Sumatra. Student learning outcomes are still low due to the methods used that are not suitable, this results in students being less active in the learning process. Therefore, it is necessary to conduct research using problem-based learning methods to see the effectiveness of student learning outcomes. The research design used is Pre-Experimental Design using the One Group Pretest-Posttest design. In this study, the instruments used include initial test questions (pretest), and final test (posttest). Pretest and posttest were used in this study to collect data. Data analysis techniques used in this study are student learning completeness, effect size analysis, and mann whitney test. Based on the research findings, it is proven that the students of class XI TITL 1 SMKN 1 West Sumatra using problem-based learning method in the subject of electrical lighting installation is very effective. Based on the results of data analysis and discussion, it can be concluded that the use of problem-based learning methods is effective in improving the learning outcomes of students in class XI TITL 1 in the subject of Electrical Lighting Installation. This can be seen from the increase in student learning after treatment. Evidenced by the level of completeness of student learning outcomes that increased and the average posttest score of 87% which was higher than the average pretest score of 73,4. In addition, the results of the effect size analysis show that the use of problem-based learning methods has a large impact on student learning outcomes of 0,78. There is a significant difference between the learning outcomes of the experimental and control classes, so the use of problem-based learning methods is said to be effective.
