Abstract
Indonesia merupakan negara agraris yang sebagian besar penduduknya bermata pencaharian di sektor pertanian hal ini didukung dengan jumlah lahan pertanian dengan kesuburan tanahnya.hal ini ditopang dengan industri pupuk yang kuat. Untuk itu dilakukan penelitian untuk menentukan kemungkinan risiko serta bahaya dari kegagalan proses pada steam turbine 103-JT milik PT. Petrokimia Gresik. Serta bertujuan untuk meningkatkan nilai safety integrity level untuk mereduksi setiap kemunginan bahaya. Dari hasil analisa HAZOP didapatkan bahwa kegagalan dengan risiko tertinggi adalah kegagalan yang disebabkan oleh tidak berfungsinya governor valve dan extraction valve dengan baik ditambah keausan pada komponen bearing,nozzle, labyrint dan gasket. Dari perhitungan SIL didapatkan hasil yang menunjukan 40% memiliki tingkat keamanan SIL 0 (governor valve dan extraction valve ), dan 60% SIL 1 (bearing,nozzle, labyrint dan gasket) Dari hasil analisa proses reduksi risiko pada 103-JT dengan menggunakan metode LOPA maka didapatkan hasil rekomendasi perlu ditambahkan adanya loop BPCS pengendalian dan speed alarm low 103-JT.

Indonesia is an agrarian country with a large portion of the population making a living in the agricultural sector, this is supported by the amount of agricultural land with fertility of the land. This is supported by a strong fertilizer industry. For this reason, a study was conducted to determine the possible risks and dangers of process failure on the 103-JT steam turbine owned by PT. Petrochemical Gresik. And aims to increase the value of
safety integrity levels to reduce every possible hazard. From the results of the HAZOP analysis, it was found that failure with the highest risk was a failure caused by the malfunction of the governor valve and extraction valve, plus wear on the bearing, nozzle, labyrint and gasket components. From the calculation of SIL, the results showed that 40% had a SIL 0 security level (governor valve and extraction valve), and 60% SIL 1 (bearing, nozzle, labyrint and gasket). hence the recommendation result needs to be added to the BPCS control loop and speed alarm low 103-JT.
