Abstract
PT. Petrokimia Gresik merupakan salah satu perusahaan penghasil pupuk terbesar dengan bahan baku utamanya adalah ammonia. Terdapat beberapa proses dalam pembuatan ammonia, salah satunya pada proses penghasil steam. Adapun komponen penting pembuatan steam adalah superheat burner karena memiliki potensi bahaya dan resiko yang menjadikan sistem bersifat hazardous. Pada penelitian tugas akhir ini dilakukan analisis untuk mengetahui peluang risiko bahaya yang terjadi. Besarnya risiko bahaya harus diimbangi dengan adanya sistem pengamanan (SIS). Sistem superheat burner dianalisis bahayanya dengan metode HAZOP serta dihitung tingkat keamanan SIL melalui metode optimisasi. Berdasarkan penelitian yang dilakukan, superheat burner memiliki risiko bahaya tinggi pada komponen TT-1005 dan PT-1018. Optimisasi dilakukan menggunakan genetic algorithm dengan variabel meliputi PFDavg, STR, dan LCC. Dari hasil perhitungan didapatkan nilai LCC aktual sebesar USD 6.171.713 dengan nilai SIL aktual adalah SIL 0. Hal ini akan berdampak pada peningkatan nilai SIL yang semula SIL 0 menjadi SIL 2 dengan peningkatan nilai PFDavg menjadi 0,004723, nilai STR sebesar 3,283x10-5, dan adanya penurunan nilai LCC sebesar USD 4.408.186. Sedangkan untuk vote arsitektur yang optimal dalam perancangan SIS ialah 1oo1 dengan teknologi smart transmitter untuk sensing element dan air operated untuk final element.

PT. Petrokimia Gresik is one of the largest fertilizer producing companies with the main raw material being ammonia. There are several processes in making ammonia, one of which is in the steam producing process. The important component of making steam is the superheat burner because it has potential hazards and risks that make the system hazardous. In this final project, an analysis is carried out to find out the chance of the danger that occurs. The amount of hazard risk must be balanced with the existence of a security system (SIS). The superheat burner system analyzed the danger with the HAZOP method and calculated the level of SIL security through the optimization method. Based on the research carried out, the superheat burner has a high hazard risk in the TT-1005 and PT-1018 components. Optimization is done using genetic algorithm with variables including PFDavg, STR, and LCC. From the calculation results obtained the actual LCC value of USD 6,171,713 with the actual value of SIL is SIL 0. This will have an impact on increasing the value of SIL which originally SIL 0 becomes SIL 2 with an increase in PFDavg value to 0.004723, STR value of 3.283x10- 5, and a decrease in the LCC value of USD 4,408,186. While for the optimal vote architecture in the design of SIS is 1oo1 with smart transmitter technology for sensing element and air operated for the final element.
