This study presents capacitor installation to reduced losses line, moreover improve voltage profile and power factor improvement. Capacitor optimization installed using modified backward forward sweep with the result that installation point and capacity appropriate. The modified backward-forward sweep have been tested on 15 BUS Kota Calang 20 kV feeder distribution, Aceh Barat. Initial simulation of feeder was result 0,85 kW line losses with 19,9753 minimum voltage. After capacitor installation on BUS 4, BUS 6, BUS 8 and BUS 13, the minimum losses line is reduced to 0,66 kW.

Currently there are several tools that can be used for the process of measuring vertical and horizontal distances in one tool, but the process of use is still difficult for the layman to use. The main objective of this final project is to design vertical and horizontal measurement tools with 2 sensors for the horizontal and vertical measurement process into 1 tool only to make it easier for the layman to use as well. This tool is equipped with Incremental rotary encoder as horizontal distance meter, Infrared sensor as vertical distance meter, and seven segment as measurement data viewer by Incremental rotary encoder and Infrared in centimeter(cm)

Design and simulation Multilevel inverter three-phase fifteen-level in this research using modulation technics of sinusoidal pulse width modulation (SPWM) in which input voltage sources that used was arranged as symetrical and separate for each phase by using free DC source in form of battery 12 Volt, 24 Volt, and 48 Volt as well as uses seven MOSFETs for switching in each phase. To produce fifteen levels, it can be done by using a combination method of battery arrangement by activating the MOSFET switching circuit according to the results of the comparison between the reference wave in the form of a three-phase sinusoidal wave and the carrier wave in the form of a free DC source by using SPWM modulation circuits. SPWM modulation circuits15level in this research was constructed by using an Op-Amp as a comparator, AND, NOT and OR gates as well as several other electronic components.The H-Bridge circuits is used to reverse the direction of the electric current so that it can to produce alternating current on the load side which is resistive and arranged in a star connection (Y), by using the PSIM simulation program, the THD value that produced for each phase was relatively the same at 5.6%.

The house light control system is manually operated, tends to forget turn off the lights when leaving the house, house owner must return to turn off the lights or leave the lights on until the houseowner returns. The use of NodeMCU ESP8266 is currently favored by internet of things based developers, other reason is the price of the module was quite cheap and programmed using the Arduino IDE allowing NodeMCU be the preferred choice. The study uses Telegram Messenger Bot as a message sender and message recipient to control home lights, using NodeMCU as a Relay controller to turn 0n - off the home lights remotely. This system can be controlled from any distance, according to tests that have been carried out this system can operate from a distance of 100 meters, 5 kilometers, even from outside the area with a distance of 2193 kilometers.

One of the topics studied in the Power Electronics course is the three-phase AC to AC converter, where the output frequency remains the same as the source voltage frequency, but the output voltage magnitude can be adjusted according to the requirements, this circuit is often referred to as a three-phase AC voltage regulator. The SCR trigger circuit functions to control the three-phase AC voltage, using six SCRs in total. The components used include an LM324, which functions as a comparator, MOC3063, diodes, and several other analog electronic components. The three-phase AC voltage source in this study uses a low-voltage supply, which is also used as a reference point for the comparator circuit, therefore, a three-phase step-down transformer circuit is required. The measurement of the output waveforms Van, Vbn, and Vcn is conducted using a digital oscilloscope with SCR triggering delay times of 1.6 ms (28.8°), 2.5 ms (45°), 3.5 ms (59.4°), 5 ms (90°), 6.6 ms (118.8°), and 7.5 ms (135°). The measured waveform characteristics align with the results obtained using computer simulations. However, the differences between the measurement results and mathematical calculations are relatively small. This is due to the manual method used to determine the triggering time by adjusting the potentiometer, which introduces the possibility of errors during measurements performed by different individuals.
