One of the state-owned companies in the electricity sectors, located in South Bandung with the main function of managing distribution installation assets (Transmission and Substation) and maintenance of distribution installation assets to maintain the continuity of efficient and reliable distribution of high voltage electrical energy. In substations, PMT is the most important component, coordination between PMT divisions must be paid more attention. One of the disturbances in PMT is the high value of contact resistance and it is not synchronous during the Open-Close process. The research was aimed to identify how much the value of contact resistance at each PMT, and how much loss of conductivity of PMT and also carried out simultaneous testing to observe the level of synchronization between phases. After various tests were carried out, by looking at the results of these tests, it could be concluded that the PMT 7A1 had no damage, and could still operate normally. Then, the purpose of maintaining high voltage electrical equipment is to ensure the continuity of electricity distribution and ensure reliability, and to extend the life of the equipment by reducing equipment damage.

Angkasapura II is a State-Owned Enterprise (BUMN) that serves air traffic travel using airplanes which cannot be separated from the need for electricity. Almost all services use electricity, without exception the PKP-PK Building or the fire fighting building. This is because this building has an integrated fire detector that is connected from every room throughout the Angkasapura II area directly with the PKP-PK Building or the fire department building. The problem is because the PKP-PK power source is still sourced from the TNI AU base and has not been sourced from PT Angkasa Pura II. It is feared that if the main source of PKP-PK electricity is interrupted, there will no longer be a backup power supply in the PKP-PK area. From the results of this study, a backup power supply line for the PKP-PK area was made from Angkasapura II, with this if the main electricity had problems, the area could operate smoothly because it had been backed up by the electricity supply from PLN and the Angkasapura II Genset. .

Uninterruptible Power Supply (UPS) is an important component that is useful for temporarily storing electrical energy. This storage is done in the UPS battery itself, the capacity of each battery is different. Indirectly this UPS is also useful in order to avoid flickering when the electric current from the PLN goes out. This is done in order to avoid damage to the electronic device. In Angkasapura II Bandung as well, UPS is used to avoid flickering which causes damage and even crashes on the plane due to a communication failure between the Pilot and the AFL. Another obstacle is the cubicle control panel circuit. This happens because when there is a blackout from the PLN UPS, the active UPS does not back up this circuit, the bad thing that happens is that the electrical control at Angkasapura will stop because the cubicle control circuit does not receive electricity supply. From the results of this study resulted in a new circuit that can read-up power automatically with the existing UPS.

The fuzzy logic method is a method that is not much different from the case that resembles the level of thinking of people's logical reasoning. It has two inputs from two different sensors with linguistic values or called membership degrees and the resulting voltage is 0 - 5.5 Volts. The PIR sensor will work optimally at a distance of 4 meters where for the sensitivity of the PIR sensor itself it can react in a time range of 3-4 seconds and for its own range of approximately 4 meters and on the LM35 sensor test that this sensor is better for temperature due to the sensitivity of detecting temperature when compared to a thermometer, this sensor will be able to stabilize the room temperature which is less precise, so that in making the room for automatic cooling the sensor works optimally in a room measuring 4 x 4 meters. ABSTRAK:Metode fuzzy logic merupakan metode tidak beda jauh dengan halnya yang menyerupai pemikiran tingkat penalaran logika orang. Memiliki dua inputan dari dua sensor yang berbeda dengan nilai linguistik atau disebut derajat keanggotaan dan tegangan yang dihasilkan dengan sebesar 0 - 5,5 Volt. Sensor PIR akan bekerja optimal pada jarak 4 meter dimana untuk sensitivitas sensor PIR sendiri dapat bereaksi pada rentan waktu 3 – 4 detik dan untuk lebar jangkauan sendiri pada kurang lebih 4 meter dan pada pengujian sensor LM35 bahwa sensor ini terhadap suhu lebih baik dikarenakan sensitivitas mendeteksi suhu apabila dibandingkan dengan termometer, maka sensor ini akan lebih dapat menstabilkan suhu ruangan yang kurang tepat, sehingga pada pembuatan ruangan untuk pendingin otomatis agar sensor bekerja secara optimal pada ruangan yang berukuran 4 x 4 meter.

The electric power system consists of several components, namely generation, distribution, transmission and load. Along with the rapid development of technology in the field of electricity today, a protection system is installed at substations, one of which is a powerbreaker (PMT) at each substation. In the event of a disturbance, the protection relay will detect and instruct the breaker to open or disconnect the circuit from the disturbance, then a circuit breaker will receive a signal from the relay and in the end will decide the circuit according toits current rating. Based on the type of PMT isolation media, PMT is divided into 4 types, one of which is the SF6 gas isolation media type. This type of PMT can be used to cut currents up to 40 KA and in circuits with a voltage of 765 KV. It must be noted that if the current is very large at the time of short circuit, then the thing that must be considered is the capacity of thebreaker itself. To determine the breaker capacity, it is sought from the largest short-circuit current, namely a three-phase short circuit. In finding a three-phase short circuit current can be simulated using the ETAP (Electric Transient Analysis Program) program. ETAP can simulatepower flow and short circuit current. The results of the calculation of the PMT capacity on the 70 KV bus are 0.324 KA and from the results of the calculation and analysis of the PMT it is included in the rating of 12.5 KA where the PMT with the rating value can decide the fault current from 0.9 KA -7.74 KA
