Abstract
Keselamatan kerja merupakan hal pokok yang perlu dipenuhi dalam aspek produksi minyak dan gas bumi. Hal ini tidak terlepas dari karakter minyak dan gas bumi sendiri yang memiliki sifat bertekanan tinggi dan mudah meledak sehingga apabila terjadi kegagalan pada sistem maka akan berdampak buruk pada manusia, lingkungan maupun kegiatan operasi itu sendiri. Untuk mengurangi kegagalan tersebut dipasanglah suatu sistem pengaman berupa pengaplikasian pressure relief device (PRD) yang berfungsi untuk mengontrol dan membatasi tekanan dengan cara mengarahkan aliran kedalam jalur tambahan. Dalam proses pemurnian minyak dan gas bumi pengaplikasian PRD sendiri salah satunya terdapat pada sistem production gas separator. Namun, berdasarkan API 581, PRD juga memiliki risiko kegagalan sehingga setiap perusahaan minyak dan gas bumi perlu melakukan inspeksi secara rutin guna menjamin keandalan dari PRD. Salah satu pendekatan untuk mengevaluasi kritikal dari PRD untuk mengatur program inspeksi dan penjadwalannya adalah dengan
menggunakan metode Risk Based Inspection (RBI). RBI merupakan sebuah pendekatan sistematis tentang metode pengelolaan inspeksi terhadap peralatan atau unit kerja yang
didasarkan kepada tingkat risiko yang dimiliki oleh peralatan atau unit kerja tersebut. Risiko ditentukan berdasarkan perhitungan kemungkinan kegagalan (Pof) dan
konsekuensi kegagalan (CoF). Penilaian risiko untuk PRD sistem Production Gas Separator didasarkan pada API RP 581 edisi ketiga. Setelah mengetahui tingkat risiko yang ada maka dievaluasi terhadap risiko tersebut. Risiko yang masih diterima bisa dijadikan acuan untuk menentukan waktu inspeksi berikutnya sampai mencapai risk target. Dari hasil yang telah dianalisa besarnya risiko pada PSV-1020A/B, PSV-1311, PSV-1312, PSV-2910, PSV-2921 dan PSV 2931 berkisar antara 0.071 m2/year – 0.49 m2/year untuk RBI Date dan berkisar antara 1.915 m2/year – 7.85 m2/year untuk RBI
Plan Date. Risiko tersebut bila dimasukkan ke dalam matriks risiko memiliki kategori risiko medium risk dan medium high risk.

Work safety is the main thing that needs to be met in the aspect of oil and gas production. This is inseparable from the character of oil and gas itself which has high pressure and explosive nature so that if a system failure occurs, it will have a negative impact on humans, the environment, and the operations themselves. To reduce this failure a safety system is installed in the form of the application of a pressure relief device (PRD) which functions to control and limit the pressure by directing the flow into additional pathways. In the process of purifying oil and gas, the application of PRD itself is one of which is in the gas separator production system. However, based on API 581, the PRD also has a risk of failure so that every oil and gas company needs to conduct regular inspections to ensure the reliability of the PRD. One approach to evaluating the criticality of the PRD to manage its inspection and scheduling program is to use the Risk-Based Inspection (RBI) method. RBI is a systematic approach to the management method of inspection of equipment or work units based on the level of risk that is owned by the equipment or work unit. Risk is determined based on the calculation of the likelihood of failure (POF) and the consequences of failure (CoF). The risk assessment for the PRD Production Gas Separator system is based on API RP 581 third edition. After knowing the level of risk there is then evaluated against these risks. Risks that are still accepted can be used as a reference to determine the next inspection time to reach the risk target. From the results that have been analyzed the
magnitude of risk in PSV-1020A / B, PSV-1311, PSV-1312, PSV-2910, PSV-2921 and PSV 2931 ranges between 0.071 m2 / year - 0.49 m2 / year for RBI Date and ranges between 1,915 m2 / year - 7.85 m2 / year for the RBI Plan Date. If the risk is included in the risk matrix it has a medium risk and medium high-risk risk category.
