Abstract
Seiring dengan perkembangan dunia industri dan jaminan
perlindungan terhadap keselamatan pekerja dan lingkungan, maka
diperlukan studi mengenai hazard dan managemen risiko. Salah satu
perusahaan yang peduli pada isu keselamatan kerja adalah
PT.Petrokimia Gresik yang merupakan salah satu produsen pupuk
terbesar di Indonesia. Dalam proses produksi PT. Petrokimia Gresik,
boiler merupakan salah satu equipment yang memiliki risiko bahaya
paling tinggi. Analisis bahaya dalam penelitian ini dilakukan
menggunakan metode HAZOP. Node yang dipakai adalah economizer,
steam drum, superheater, dan burner yang merupakan beberapa
komponen utama penyusun boiler. Berdasarkan hasil analisis,
diperoleh hasil bahwa komponen yang memiliki risiko bahaya paling
besar adalah pressure indicator inlet steam drum, temperature
indicator (TI-6211) dan temperature indicator outlet superheater (TI6214),
dengan risiko bernilai 5 (extreme) menggunakan standard
AS/NZS 4360:2004. Masing-masing node pada boiler memiliki SIL 1,
dengan risk reduction factor bernilai 50 untuk economizer, 39,1 untuk
steam drum dan 30 untuk superheater dan burner, yang menunjukkan
rendahnya tingkat reliability sistem. Untuk menurunkan risiko dan
meningkatkan reliability sistem, maka dilakukan perawatan dan
kalibrasi secara rutin, penambahan redundant transmitter, serta test
kinerja sensor,transmitter dan final control element setiap 1 bulan
sekali. Bahaya paling besar pada seluruh node adalah kebakaran. Oleh
karena itu, dilakukan analisis emergency response plan untuk
kebakaran yang mencakup tanggungjawab tiap divisi, langkah
pencegahan, serta langkah penanganan

In line with the advancement in the industry and protection assurance of
health, safety and environment for the workers. Thus necessary to held
the study about hazard and risk management. One of the company
concerns with the health safety and environment issues is PT.Petrokimia
Gresik, which was one of the biggest fertilizer producer in Indonesia.
During production process in PT. Petrokimia Gresik, boiler become one
of highly risk equipment. Hazard analysis in this research using
HAZOP method. Node study that have been identified is economizer,
steam drum, superheater, and burner, which was the main component
composing boiler. According to analysis result, some components
having highest hazard risk are pressure indicator inlet steam drum,
temperature indicator (TI-6211) and temperature indicator outlet
superheater (TI-6214), which had extreme risk with tehe value of using
AS/NZS 4360:2004 standard. Each node in the boiler having SIL 1
criteria, with the value of risk reduction factor 50 for economizer, 39,1
for steam drum and 30 for superheater and burner, means that there
having low level of system reliability. Treatment can be applied to
decrease hazard risk and increase system reliability are arranging
maintenance and calibration routinely, adding transmitter redundant,
and arranging proof test interval in the sensor, transmitter, and final
control element once a month. Highest hazard risk in the whole node of
boiler is fire. Thus have been done emergency response plan analysis
for fire condition to identifying the responsibilities of each division,
preventing, and also handling step.
