Electrical energy is a primary need at this time, which almost all human activities require electricity. The electrical energy we use today is a conversion from other energy, partly derived from fossil energy, which is energy that cannot be renewed and will run out if it is continuously explored and exploited. Solar energy is a renewable energy source that has the potential to be converted to electrical energy using solar panels or so-called photovoltaics. Photovoltaic has a drawback in its use, namely the output value is very dependent on environmental conditions. To maximize the power efficiency between the photovoltaic output and the power to be used by the load, a method is needed, namely Maximum Power Point Tracking (MPPT). In the application of this MPPT DC-DC Zeta converter is used with a hill climbing algorithm to achieve the value of the output voltage and current at maximum power. With this method, it is expected that MPPT control is reliable and easy to apply. In this study, the type of photovoltaic module used is the 60 Wp monocrystalline type with sampling data once an hour from 09.00 - 17.00 WITA, the tracking speed data obtained by the modified hill climbing algorithm is 0.142 seconds on average with an average efficiency of 99.969 %.

Resulting output voltage is not constant due to light intensity and surface temperature of the solar panels. To overcome the output voltage of solar panels that tends to fluctuate, is to add a DC-DC converter to the output side of the DC-DC Converter used in this study is the Quadratic Boost Converter type which has a role to increase the output voltage of the monocrystalline type solar panel so that it remains constant at 24V DC. using Mamdani Fuzzy Logic Control as a method of controlling PWM switching. The results obtained from this study are that the quadratic boost converter can keep the output voltage of the solar panel constant at 24V, with low ripple voltage and overshoot. The Mamdani fuzzy logic method used can produce a constant output voltage value with a rise time of ± 5 seconds. The efficiency obtained from this converter hardware is quite good, ranging from 76% - 88%.

Electricity demand is increasing with the development of technology in various fields, such as agriculture, medicine, automotive and others. But for controlling electricity in a room or building there are still found to be less efficient. In controlling electricity or remote control using SMS need to pay attention to the signal that is on the SIM800L sms module. The way to get a signal is the need for power supply above 2 amperes for this SIM800L module. This final project produces a tool that can control electricity in a room that is connecting and disconnecting the electricity supply using an RFID card which can turn on and off each room, even more than two outputs at once, and use SMS media for remote control.

The 3 phase induction motor in its use is increasingly growing, so research on the speed regulation of the 3 phase induction motor is also increasingly being studied. This is because the use of 3 phase induction motors in industry and especially hybrid vehicles is increasingly being developed. But there are some disadvantages of induction motors, one of which is the characteristics of non-linear parameters, especially rotor resistance which has varying values for different operating conditions, so it cannot maintain its speed constantly if there is a change in load. This of course can affect the performance of an induction motor. To get a constant speed and better system performance on load changes a controller / controller is needed. This study aims to model the parameters used in Direct Field Oriented Control (DFOC) using Matlab SIMULINK. With the controlled dq parameter, the induction motor will be more stable, because the dq parameter determines the stability of the changes in torque and flux in the induction motor. In the results of implementation, it can be seen that the use of DFOC can be used as an approach in the speed regulation of the induction motor. and with the use of PI controls it can help the output response get better with a shorter response time to reach the reference value.

One of the main components of wind power plants that can be developed is the Permanent Magnet Synchronous Generator (PMSG). In this research, PMSG design will be carried out using Finite element method software with Geometry Variations of Permanent Magnet Synchronous Generator with a combination of 12 8-pole slots which will then be modeled on Finite element method software. In one variation of this generator geometry has been successfully created with good efficiency. This model will argue for the specifications of variations 1, 2 and 3 and are analyzed by comparison test scenarios and loading with load R. The generator with a no-load test simulation produces between variations in variation 1 of 10.93 volts, variation 2 of 12.67 volts, variation 3 of 13.77 volts. When testing load with load resulted in an efficiency of variation 1 of 20.5%, variation 2 of 19.6%, and variation 3 of 33.4%.

Electrical energy is one of the basic needs for humans today, almost every activity we do is inseparable from the use of electrical energy, the use of electrical energy must be paid according to the amount and duration of electricity use in electricity management authorized by state-owned companies, namely PT. PLN Persero using kWh meter. In the postpaid type kWh Meter (Kilo Watt Hours), we cannot know the amount of electrical power that has been used in real-time.This research aims to design a system that can acquire power consumption in kWh andpower consumption costs (Watts) real-time by utilizing the ACS712 current sensor and voltage sensor circuit as input current and voltageand then processed by Arduino Uno for processing. The data is in an application interface, then the usage data is stored automatically in the data base local by the MySQL application.The results of this study are by comparing the calculation of power consumption (Watt) and the nominal cost of electricity in anapplication interface. After the data is obtained, it can be concluded that the readings from input the current and voltage sensor in this system are not accurate and unstable, so that the comparison of the value by the kWh meter is 4.8 kWh with a nominal cost of Rp. 7,745.76, while in this system design the power value obtained is 9.08 kWh with a nominal usage fee of Rp. 14,652.39. Then the difference in value between the calculation of kWh and the design of this system is 4.28 kWh, with a nominal difference in the cost of using it of Rp. 6,906.63.
