Various efforts have been made to operate the system and implement a reliability system to keep the electricity system from experiencing blackout. But the possibility of a blackout still exists. The system blackout incident on Sunday, August 4, 2019 at 500 kV Java Bali is an evaluation and challenge for PLN to be able to maintain system reliability and also find the most effective way to restore the system in a short time when a blackout occurs. There are several things that become priority for recovery, when the Jakarta and Banten systems are in <br>a blackout condition. The first priority is to secure the supplies to the VVIP location and the next priority is to send voltage to the large power plant so that the plant can be operated immediately. Therefore, optimization is needed in the system recovery procedure so that it is expected to restore the system in the shortest possible time. PLTMG Senayan is a generating unit prepared as a backup supply for the MRT, but at the same time it can also be used for black start to the power plant, in this case the power plant in Priok.</p> Tri Ongko Priyono Rayi Prionggo adjie Copyright (c) 2021 2021-01-02 2021-01-02 9 1 45 54 ANALISIS PENGARUH JUMLAH LILITAN KOIL PADA PEMANAS MENGGUNAKAN TERMOKOPEL TIPE K DENGAN METODE INDUKSI https://journal.teknikunkris.ac.id/index.php/elektro/article/view/397 <p>Induction Heater is a technology that has long been made and used in industries that require metal materials in its production, usually in melting metal, a considerable amount of fuel is required because the melting point of the metal itself is quite high.

After the use of the GTO, the officer's job was replaced with an Automatic Vehicle Classification (AVC) electronic device to automatically classify the types of vehicles so that toll rates could be issued according to the type of vehicle. To solve this problem, the AVC device is added with an inframerah sensor as a control system for the direction of a vehicle that is moving backwards. This additional inframerah sensor consists of a transmitter and receiver module to detect the direction of the vehicle, which is installed at a distance of 50 cm from the profile scanner sensor. From the results of the tests carried out, the results of the sample transaction data show that the maximum error percentage before the addition of an inframerah sensor is 0.91% and the maximum error percentage after adding an inframerah sensor is 0.54% so that there is a decrease in error by 0.37%. Thus, optimization of automatic vehicle classification can be achieved.</p> Sri Hartanto Trio Sasmito Copyright (c) 2022 2021-01-02 2021-01-02 9 1 64 71 RANCANG BANGUN ALAT PINTU GESER OTOMATIS MENGGUNAKAN MOTOR DC 24 V https://journal.teknikunkris.ac.id/index.php/elektro/article/view/398 <p>Automatic Doors are often found in many places, such as in malls, banks, companies and many other places.
