Penelitian ini juga bertujuan untuk mengetahui potensi-potensi bahaya apa saja yang dapat timbul dari kegiatan pemboran khususnya sumur S-10 yang terletak di lapangan A milik PT X serta tingkat resiko dan setiap potensi bahaya yang mungkin timbul dan kegiatan tersebut Dari studi ini selanjutnya diharapkan dapat memberikan rekomendasi langkah-langkah kontrol yang dapat dilakukan untuk mencegah terjadinya.
Oil and gas industry is the high risk operation. Because of safety reason, oil and gas company should have a good system to Identify and analyze all potential hazards and risks before execute their activities especially in drilling activities.
The objective of this research are to examine the validity of all supporting data such as well interpretation data, drilling equipment performance and well location condition. The approach of this study is to evaluate all potential hazards and calculate the level of its risk which is exist on drilling activities especially at S-10 Well, Filed-A that can practically use to determine the control action to avoid incidents and/or accidents in a workplace.
Tesis ini membahas tentang penilaian risiko yang dilakukan di Stasiun Pengumpul Gas Y PT X. Metode penilaiaan risikonya menggunakan penggabungan 2 (dua) analisis yaitu analisis risiko proses melalui metode Hazops dan analisis risiko peralatan melalui metode risk based inspection (RBI). Penelitian ini adalah penelitian observational dengan pendekatan analisis risiko semikuantitatif. Hasil penelitian ini memberikan gambaran tingkat risiko proses dan peralatan di Stasiun Pengumpul Gas Y, dimana tingkat risiko tertinggi ada pada proses dan peralatan tanki penampung kondensat. Tingkat risiko tersebut diperoleh dari kombinasi kemungkinan kejadian (likelihood) dan konsekuensi/keparahan dampak (severity). Selain itu dihasilkan butir-butir rekomendasi untuk mengendalikan risiko sampai pada risiko yang dapat diterima. Kata kunci : Risiko, likelihood, severity/konsekuensi.
The focus of this research is risk assessment carried out at Gas Gathering Station Y in PT X. Risk assessment method applied are combination between process hazard analysis by using Hazops method and equipment risk analysis by using risk based inspection (RBI) method. The research is observational by semiquantitative analysis approach. The research gives description regarding process and equipment risk level at Gas Gathering Station Y, which is the highest risk level is on the process and equipment named condensate storage tank. Risk level is calculated by combining likelihood and severity/consequence value. The research also recommend several risks control to reduce risk to be acceptable risk. Key words : Risk, likelihood, severity/consequence.

Loading, hauling, and dumping activities are high risk acitivities in mining, based on the literatur review (Kecojevic dan Radomsky, 2004; MSHA, 2018). During the period of 2015 to 2018, there were several accidents related to loading, hauling, and dumping activities that causing fatalities at PT. XYZ. Therefore, detail risk assessment need to be performed of these three activities at PT. XYZ. The failure modes and effects analysis (FMEA) method was used in this study. 71 potential failure modes were identified , consist of 7 failure modes at preparation step, 18 failure modes at loading process, 35 failure modes at the hauling process, and 11 failure modes at the dumping process. About 25% of the 71 potential failure modes were very high risk level. They were dumptruck tire failure due to scattered sharp stones, brake failure while operating dumptruck, tire damage while operating, loader unit crahsed with big stones while maneuvering, loader cabin hit by hanging stones while loading, scratched tire of the loader unit due to scattered sharp stones, the dumptruck caught in the labile surface, and light vehicle fell down from benches. As recommendation, it is important to strengthen maintenance of heavy equipment, improve safe environment, and increase operator competence.
Key words: Failure modes and effects analysis (FMEA), Safety risks, Risk level, Loading, Hauling, Dumping.
