Abstract

Safety merupakan syarat penting dalam menjalankan kegiatan produksi pada industri. Keamanan dalam pabrik perlu diperhatikan terutama terhadap node berbahaya seperti superheater dan burner. Besarnya risiko bahaya harus diimbangi dengan adanya sistem pengamanan seperti Safety Instrumented System (SIS). Sistem pada superheater dan burner dianalisis bahayanya dengan metode Hazard and Operability (HAZOP) serta dihitung tingkat keamanan Safety Integrity Level (SIL) melalui metode Layer of Protection Analysis (LOPA). Berdasarkan penelitian yang dilakukan pada tugas akhir ini, superheater dan burner memiliki tiga kategori resiko diantaranya high sebesar 25%, sedangkan hasil yang sama pada kategori low dan medium sebesar 37,5%. Perhitungan nilai SIL yang telah dilakukan dengan metode LOPA menunjukkan angka SIL 0 untuk loop sistem yang mewakili jalannya proses kecuali pada TV-1020 yang bernilai NR (Not Required). Rekomendasi yang diberikan untuk meningkatkan nilai SIL atau reduksi resiko maka ditambahkan alarm HH LL pada (XV-1421-A & XV-1241-B), (PV-1018-A & PV-1018-B) dan PV- 1013. ================================================================================================================== Safety is a important requirement in carrying out production activities in the industry. Safety in the factory need to be considered, especially against malicious nodes such as superheater and burner. The magnitude of the risk of harm must be balanced with the system of safeguards such as safety instrumented system (SIS). So the system in superheater and burner analyzed by the method of Hazard and Operability (HAZOP) and the safety level is calculated Safety Integrity Level (SIL) through the method of Layer of Protection Analysis (LOPA). Based on research conducted in this thesis, superheater and burner has three categories of such high risk by 25%, while the same results in the category of low and medium of 37.5%. SIL value calculation has been done by the method LOPA showed SIL 0 for loop systems that represent the course of the process except the TV-1020 is worth NR (Not Required). Recommendations are given to increase the value of SIL or risk reduction then added LL HH alarm on (XV-1421-A & XV-1241-B), (PV-1018-A and 1018-B PV) and PV-1013.
