Abstract
PT. Pupuk Sriwidjaja Palembang (Pusri) merupakan salah satu produsen pupuk terbesar di Indonesia. Sebagai salah satu pelopor produsen pupuk urea di Indonesia tingkat produktivitas Pusri harus tetap terjaga. Salah satu faktor yang mendukung hal tersebut adalah kontinuitas suplai daya dan lingkungan kerja yang aman bagi para pekerja Pusri. Salah satu penyebab terputusnya suplai daya yaitu terjadinya gangguan hubung singkat. Gangguan hubung singkat juga dapat menyebabkan fenomena busur api yang berbahaya bagi manusia maupun peralatan itu sendiri. Hal ini tentu berdampak langsung pada produktivitas Pusri. Oleh karena itu koordinasi proteksi yang baik dan Personal Protective Equipment (PPE) yang sesuai dibutuhkan. Hasil simulasi menggunakan ETAP 12.6 menunjukkan pada kondisi existing sistem kelistrikan Pusri IB terdapat beberapa kesalahan koordinasi yang menyebabkan nilai incident energy terlalu besar melebihi standar NFPA 70E 2009, sehingga perlu dilakukan penyetelan ulang pada peralatan-peralatan pengaman. Setelah melakukan resetting koordinasi proteksi, dilakukan simulasi dan perhitungan menggunakan standar IEEE 1584-2002 untuk menentukan PPE yang sesuai dengan kategori risiko bahaya pada daerah tersebut. Hasil dari resetting koordinasi proteksi adalah terdapat beberapa perubahan nilai incident energy baik peningkatan maupun penurunan karena pada kondisi sebelumnya terdapat peralatan pengaman yang bekerja terlalu cepat maupun terlalu lambat. Setelah resetting juga pada bus-bus yang memiliki nilai incident energy melebihi standar NFPA 70E 2009 mengalami penurunan yang signifikan.

PT. Pupuk Sriwidjaja Palembang (Pusri) is one of the biggest fertilizer producers in Indonesia. As one of the pioneers of urea fertilizer producers in Indonesia, Pusri's productivity level must be maintained. One of the supporting factors is power supply continuity and a safe working environment for Pusri workers. One of the causes of power supply disconnection is short circuit fault. Short circuit fault can also cause an arc flash phenomenon that is dangerous for human and the equipment itself. This certainly has a direct impact on Pusri's productivity. Therefore a good coordination protection and appropriate Personal Protective Equipment (PPE) is needed. The simulation results using ETAP 12.6 show that in the condition of the existing electrical system Pusri IB there are some coordination errors that cause the incident energy value is too big exceeds the NFPA 70E 2009 standard, so the protection equipment needs to be reset. After resetting the protection coordination, simulations and calculations were carried out using the IEEE 1584-2002 standard to determine PPE according to the hazard risk category in the area. The result of resetting protection coordination is that there are several changes in incident energy values, both increases and decreases because in the previous condition there were protection equipment that worked too fast or too slowly. Also after resetting busses whose incident energy value exceeds the NFPA 70E 2009 have been decreased.
