Abstract
Dalam proses berjalannya industri, kontinuitas pasokan listrik menjadi faktor penting untuk menjaga efisiensi dan keandalan proses produksi. Sistem kelistrikan yang handal merupakan sistem kelistrikan yang kontinuitasnya baik dan dapat diandalkan. Untuk menjamin kontinuitas tersebut, sistem kelistrikan harus memiliki sistem koordinasi proteksi yang baik. Salah satu perangkat proteksi yang umum digunakan adalah Overcurrent Relay (OCR) jenis waktu invers, yang berfungsi memutus arus saat terjadi gangguan arus lebih. Namun, pengaturan Time Dial Setting (TDS) pada OCR secara manual seringkali tidak optimal dan memakan waktu. Penelitian ini bertujuan untuk menghitung nilai TDS secara optimal dengan menggunakan metode Adaptive Modified Firefly Algorithm (AMFA). Dari penelitian yang telah dilakukan diperoleh kesimpulan bahwa nilai TDS yang dihasilkan oleh metode AMFA sesuai dengan nilai TDS minimum dari hasil perhitungan manual. Kemudian nilai TDS yang dihasilkan oleh AMFA disimulasikan pada perangkat lunak ETAP dan didapatkan hasil yang sesuai dengan batas keamanan yang diatur pada AMFA yaitu rele beroperasi pada waktu minimal 0.1 detik dan CTI antar rele 0.2 detik. Dari hasil penelitian terbukti bahwa metode AMFA berhasil dalam menghitung nilai TDS yang optimal.

In industrial operations, the continuity of power supply is a crucial factor in maintaining the efficiency and reliability of production processes. A reliable electrical system is one that ensures continuous and dependable power delivery. To guarantee this continuity, the electrical system must have a well-designed protection coordination scheme. One commonly used protection device is the Inverse Time Overcurrent Relay (OCR), which functions to disconnect the circuit when an overcurrent fault occurs. However, manually setting the Time Dial Setting (TDS) of OCRs is often inefficient and time-consuming. This study aims to calculate the optimal TDS values using the Adaptive Modified Firefly Algorithm (AMFA) method. From the research conducted, it was concluded that the TDS values generated by the AMFA method correspond to the minimum TDS values obtained through manual calculations. These AMFA-generated TDS values were then simulated using ETAP software, and the results complied with the safety limits set by AMFA, namely that the relays operate with a minimum time of 0.1 seconds and a coordination time interval (CTI) of 0.2 seconds between relays. The results of the study shows that the AMFA method successfully calculates optimal TDS values.
