Abstract
PT. Pertamina RU V Balikpapan akan diintegrasikan sumber listrik dengan PT. PLN. Maka akan terjadi perubahan pola operasi generator pada sistem sehingga perlu dilakukan analisis sistem proteksi ulang. Sistem proteksi bertujuan untuk untuk mengisolasi gangguan secara cepat, selektif, dan koordinatif sehingga kerusakan pada sistem dapat diminimalisir dan kontinuitas tenaga listrik dapat terjaga dengan baik. Hal penting yang harus diperhatikan dari koordinasi proteksi khususnya pada rele arus lebih adalah pengisian parameter TDS (Time Dial Setting). TDS mengatur waktu operasi rele dalam mengamankan suatu gangguan. Umumnya nilai TDS ditentukan menggunakan perhitungan manual untuk mendapatkan nilai TDS minimum. Namun untuk mendapatkan nilai TDS yang tepat dalam pengkoordinasian dengan rele lain masih menggunakan metode trial and error. Pada tugas akhir ini akan dibahas tentang cara perhitungan time dial setting inverse time overcurrent relay dengan metode adaptive modified firefly algorithm pada sistem kelistrikan di PT. Pertamina RU V Balikpapan mempertimbangkan integrasi dengan PLN untuk mendapatkan nilai TDS yang minimum. Hasil dari tugas akhir ini adalah mendapatkan nilai TDS minimum pada beberapa kasus jenis tipikal seperti saluran terpanjang, pertimbangan waktu operasi LVCB, dan saluran yang pendek agar dapat teteap terkoordinasi dengan baik dengan saluran panjang yang terpasang pada bus yang sama.

PT. Pertamina RU V Balikpapan will be integrated with electricity sources with PT. PLN. Then there will be a change in the generator operating pattern on the system so that the protection system needs to be analyzed again. The protection system aims to isolate the interference quickly, selectively, and coordinatively, so that the damage to the system can be minimized and the continuity of electric power can be maintained properly. The important thing that must be considered from protection coordination, especially in overcurrent relays is filling the TDS (Time Dial Setting) parameter. TDS regulates the relay operation time in securing a disturbance. Generally, the TDS value is determined using a manual calculation to obtain a minimum TDS value. However, to get the right TDS value in coordinating with other relays it still uses trial and error methods. This final project will discuss how to calculate the time dial overcurrent relay inverse setting with the adaptive modified firefly algorithm method in the electrical system at PT. Pertamina RU V Balikpapan considering new integration with PLN to obtain a minimum TDS value. The result of this final project is to obtain a minimum TDS value in some cases typical types such as the longest channel, consideration operation time of LVCB, and short channels so that it can be well coordinated with long channels installed on the same bus.
