Abstract

Tenaga matahari merupakan energi alternatif yang paling banyak digunakan karena mudah di dapatkan dan tidak memiliki resiko yang berbahaya bagi mahluk hidup dibumi, salah satu contohnya adalah solar tracker yang merupakan salah satu solusi untuk mendapatkan energi listrik dari tenaga matahari.  Solar tracker juga sudah banyak dikembangkan baik itu solar tracker satu axis maupun solar tracker dua axis tetapi dari permasalahan yang ada, sistem penggerak solar tracker masih menggunakan motor penggerak yang menyebabkan energi yang dikonsumsi motor penggerak lebih banyak dibandingkan energi yang tersimpan. Berdasarkan permasalahan tersebut dibuatlah suatu alat solar tracker dua axis dengan menggunakan penggerak air dengan menggunakan MPPT dimana penelitian ini adalah pengembangan dari penelitian sebelumnya, yaitu solar tracker dua axis menggunakan penggerak air tanpa menggunakan MPPT. Berdasarkan hasil pengujian dari pukul 07.00 wib s/d 17.00 wib daya yang dihasilkan solar tracker menggunakan MPPT menghasilkan daya maksimum sebesar 17,1 Watt. Hasil ini menunjukkan terjadi peningkatan daya sebesar ± 2 % dibandingkan solar tracker dua axis menggunakan penggerak air tanpa menggunakan MPPT. Pengujian dilakukan dengan menggunakan solar sel yang sama yaitu 20 wp

Abstract

The frequent use of three-phase induction motors in the factory continuously can cause the motor to experience disturbances. One of them is a short circuit current that causes a decrease in motor speed and increases the motor temperature. To overcome this problem, a protection system is designed that protects the motor from short-circuit currents in phase-neutral. The protection system is designed using the ACS712 30A sensor as a short-circuit current reader with a minimum reading of 2A and a maximum of 25A. When a short circuit occurs, the SSR 25DA will disconnect the source from the mains circuit. The results of the demonstration, the short-circuit current measurement values ​​are 3.20A and 2.22A with 56Ω and 68 resistance. The short-circuit current with a resistance of 1.5Ω is not read by the ACS712 sensor due to overload, therefore the short-circuit current value obtained from the calculation is 146.7A. From the demonstration, it can be concluded that the resistance on the resistor affects the short circuit current value that is read. This is justified by Ohm's Law which reads that the electric current in an electric load is directly proportional to the voltage and inversely proportional to the resistance.

Abstract

In the current global climate, humans will feel a big impact, especially in terms of energy. We must be more efficient in the use of energy, especially in the use of electrical energy. In Indonesia itself, household goods and equipment that are often used are generally inductive in nature. This inductive nature makes the use of electrical energy more wasteful and less efficient. The purpose of this research is to design a control system to improve the power factor of household loads using a capacitor bank. When the load is operating, the current, voltage, and power factor values ​​will be read by the sensor which is then sent to the microcontroller. After the cos phi value is known, the microcontroller will process the control program and give a command to the relay module to activate the capacitor bank. After activating the capacitor, the sensor reads the current, voltage, and power factor values ​​again to determine the change in cos phi until it reaches the desired cos phi value. Based on the test results on 4 types of loads that were measured cumulatively, the average initial power factor value of 0.74 rose to the ideal power factor value of 0.95.

Abstract

A water pump with a low power factor results in an increase in the value of the current and reactive power, this can result in an increase in the reduction of the water pump efficiency. The purpose of this research is to design a control system to improve the power factor (cos phi) of the water pump automatically using a capacitor bank. When the motor operates, the current, voltage and power factor are read by the PZEM-004T sensor which is then sent to the Arduino. The data from the sensor is used as a basis for calculations to determine the value of the capacitor required by the water pump. Once the capacitor value is known, the Arduino processes the control program to activate the appropriate capacitor bank. This process will take place automatically when the load changes. Based on the test results on one single-phase water pump, the average water pump power factor can be fixed automatically to above 0.9 and the working current of the water pump drops from 0.96 A to 0.73 A as well as the reactive power. There is a difference in the reading from the measuring instrument and the calculation result with an average percentage of 0.2% due to the rounding of the calculation value in the program and also influenced by the accuracy of the reading of the measuring instrument used.

Abstract

Controlling equipment using voice commands is still not widely applied to electric cars. Generally, electric car equipment is still mostly controlled electrically. To optimize the control of this equipment, it is necessary to develop control via voice commands via smartphones. The purpose of controlling equipment using voice commands is to increase the ease and safety of users in controlling electric car equipment. The methodology used in this research involves changing voice commands through the speech recognizer contained in the SKMML application that has been developed and testing the response of electric car equipment when given a voice command based on a predetermined command code. From the test results, when the wiper electric car equipment is given a voice command, the percentage of success is 100% in the no-noise condition and the success percentage is 96% in the noise-inducing condition, with a duration of response to the voice command of 4 seconds. The failure of the tool response is due to poor articulation and intonation of voice commands, which makes it difficult for the speech recognizer to recognize voice commands that have been spoken.

Abstract

 A generator is a machine that is needed to produce energy that is almost used all over the world. There are two kinds of generator magnetic field generators, there are those that use permanent magnets and non-permanent magnets with generation using an excitation system. From the two magnetic sources above, I conducted research using non-permanent magnets aimed at knowing the magnetic flux produced. Because the magnetic flux produced is not constant, a study is needed to find out a good excitation source to produce a constant magnetic flux and produce electrical energy as desired. The generator has two main parts, namely the satator and the rotor where the stator is a stationary part and has the function of generating energy while the rotor is a moving part and has the function of generating a magnetic field. In my research, I changed the sator part as a generator of electrical energy. The results obtained from testing this non-permanent magnet generator are 6 experiments using different stator coils. From the results of these tests, the results of the AC power supply were obtained using a coil with the lowest inductance value (225uH) 0.049Vac and using a coil with the highest inductance value (49.8mH) 1.58Vac. From the test results, it can be concluded why the resulting voltage is too small for the magnetic flux generated because the value is not constant, it can affect the load, as well as rpm rotation and other things.

Abstract

This study designs an electric car battery charging system using solar panels and calculates the cost or tariff charged from the charging. The method used in making this research is data collection, testing and data analysis. Solar panels as a source of supply absorb sunlight and convert it into electrical energy. Then the buck-boost converter regulates the voltage that will enter the battery to match the required charging voltage. The test was carried out using a 12 Volt 7 Ah battery, so the required voltage was at least 13 Volts to be able to carry out the charging process. The length of charging time depends on the current generated, the greater the current flowing, the faster the charging process will be. The current sensor and voltage sensor INA219 are used to read the current and voltage that enter during the battery charging process and are controlled by Arduino Mega 2560. When the battery is full the current will be cut off automatically using a relay. This tool is also equipped with inputs in the form of start, stop and reset buttons so that the charging process can be more efficient. The calculation of the cost or tariff for charging an electric car follows the regulation of the Minister of Energy and Mineral Resources (ESDM), which is Rp. 1,650 per kWh. The cost calculation in the electric car charging process is displayed on the display using an 20x4 LCD.
