The need for electricity in Bali is increasing along with the growth of technology and developmentin Bali, so the quality of electricity distribution to customers must also be improved. This study took anexample from the 2018 case, Palapa Feeder used 2 reclosers which had an index value that did not meetthe standard of the reliability index value. When the Palapa Feeder only used LBS, SAIFI value was2.1055 and SAIDI was 7.2960, when the LBS was changed to recloser the SAIFI value was 1.203 andSAIDI was 4.091. When a recloser was added again the SAIFI value became 1.016 and SAIDI became3.4088. The use of 2 reclosers on a feeder is less effective, because if they are placed at a close distance,then there will be two devices work simultaneously when there is a disturbance so that the area which isnot affected by the disturbance will also experience a power outage. Therefore it is necessary to design arecloser placement point in order to obtain lower reliability index value in order to meet the PLN standard(SPLN) No. 68-2: 1986, World Class Company standards, World Class Service standards, and alsoobtained the optimum recloser location and more efficient.The design of recloser placement is carried out using the Quantum Genetic Algorithm method,which is an evolutionary algorithm based on the concept of quantum bits (qubits). The purpose of thismethod is to minimize the SAIDI and SAIFI value in order to obtain lower reliability index and meet thestandards in order to obtain an optimum recloser location. The results of the recloser placement designusing the QGA method show that the local optimum recloser location is in section 2 at point 56 with thehighest fitness value is 4.9715 and a SAIDI value is 1.8951 decreased by 44.4% and SAIFI value is 0.9978decreased by 1, 78%, and it is proven that the recloser placement design using the QGA method hassucceeded in obtaining local optimum with better SAIDI SAIFI index results and has met the PLN (SPLN)standard No. 68-2: 1986 with SAIDI 3,33 and SAIFI 1,2 and also meets World Class Company and WorldClass Service standards with SAIFI 3 (times/customer/year) and SAIDI 1,66 (hours/customer/year).

In everyday life we often use the name LPG gas even as basic needs. However, in its use itcan pose a threat because of a large enough LPG gas. The occurrence of gas leaks when there areno people around the leak is very difficult to detect especially lethal substances contained in LPG gas.To reduce fires caused by LPG gas leaks, a monitoring system is needed to monitor if a leakoccurs.The prototype method for monitoring room temperature and gas detector leak using theArduino uno 328 mitrocontroller by connecting ESP8266 for wifi connection. ESP8266 will send datawhen the MQ2 sensor reads a gas leak, as well as changes in room temperature that is read by theDHT11 sensor by sending the sensor reading data to Arduino ATmega 328 first to be processed intothe response data of the device and data that will be displayed on the blynk application.The result ofthe achievement of this research is that the measurement of leaky gas using the MQ2 sensor canalready be displayed using the avo meter by obtaining the voltage results. Real gas leakagemeasurements in the field can be displayed on mobile phones through the Blynk application media.The leaked gas graph can be displayed in the Blynk application by getting the minimum andmaximum results. The ESP8266 module must be located in an area or location that has a Wi-finetwork in order to send notifications properly according to the instructions on Arduino ATmega 328.

This research was conducted to obtain the optimal DG location with the aim of minimizing power losses in feeders. Penyulang Abang has a length of 207,946 kms with power losses of 1,105 MW. One way to reduce power losses is to install distributed generation. Distributed generation is installed in four Abang feeder locations. Optimization is done by using the Quantum Genetic Algorithm (QGA) method. Quantum Genetic Algorithm is an evolutionary algorithm. Genetic Quantum Method Algorithms are based on the concept of quantum bits (qubit) and the superposition of quantum mechanical forms. The purpose of this method is to select the best results from the results obtained. The final result of the QGA method is the most efficient distributed generation and capacity placed in several Abang feeder locations, namely buses 1, 5, 7 and 302 with capacities of 0.374 MW, 1,894 MW, 1,988 MW and 0.500 MW, respectively. So that the power losses are reduced to 0.234 MW.
