Abstract

Strategi pemeliharan berbasiskan risiko seperti Risk-Based Inspection (RBI) adalah suatu proses penilaian dan manajemen risiko yang fokus pada pelepasan fluida dari peralatan pada fasilitas pengolahan dikarenakan kerusakan material dengan menganalisis probabilitas dan konsekuensi kegagalan. Sehingga untuk industri petrokimia seperti PT. Pupuk Kalimantan Timur khususnya peralatan heat exchanger 1-E-501 SG Waste Heat Boiler dan 1-E-502 SG Boiler Feed Water dilakukan analisis dengan metode semi-kuantitatif dalam menentukan tingkat risiko, interval dan metode inspeksi. Dari hasil yang didapatkan tingkat risiko tertinggi berada pada peralatan 1-E-501 dengan tingkat medium risk (1E). Interval inspeksi ditentukan dari MTTF dengan mengunakan distribusi Weibull pada 1-E-501 dan 1-E-502 adalah setiap 2.3 dan 2.6 tahun. Metode inspeksi yang tepat adalah PT, AUBT, VT, dan Impact Testing. Sedangkan konsekuensi finansial 1-E-501 WHB dengan spesifikasi yang lebih tinggi dan dimensi yang lebih bebas namun memiliki risiko finansial yang lebih kecil yaitu Rp. 854.474.736 dibandingkan dengan peralatan 1-E-502 SG BFW sebesar Rp. 1.715.575.158. ========================================================== Risk-based maintenance strategies such as Risk-Based Inspection (RBI) is assessment processes and risk management that focused on the loss of the fluid in processing facilities due to material damage by analyzing the probability and consequences of failure. So, for the petrochemical industry such as PT. Pupuk Kalimantan Timur especially heat exchanger equipment 1-E-501 SG Waste Heat Boiler and 1-E-502 SG Boiler Feed Water were analyzed by using semi-quantitative methods in determining risk level, intervals, and inspection methods. From the results obtained, the highest risk level is in 1-E-501 equipment with a medium risk level (1E). Inspection intervals determined from MTTF by using Weibull distribution on 1-E-501 and 1-E-502 are every 2.3 and 2.6 years. The appropriate inspection methods are PT, AUBT, VT, and Impact Testing. While the financial consequences on 1-E-501 WHB with the higher specifications and dimensions but also have the smaller financial risk that Rp. 854,474,736 compared to 1-E-502 SG BFW equipment of Rp. 1.715.575.158.
