Abstract

Thermal Oxidizer (TOX) merupakan alat yang berfungsi untuk membakar limbah gas berbahaya (waste gas) yang memiliki kandungan racun tinggi menjadi gas buang (flue gas) dengan konsentrasi racun rendah.Sehingga untuk menjaga keberlangsungan proses,maka untuk meminimalisir tingkat resiko metode identifikasi resiko, akar penyebab masalah dan langkah mitigasi yang sesuai serta efektif.Oleh karena itu dalam penelitian ini, analisis resiko pada kondisi operasi unit Thermal Oxidizer menggunakan Metode Fuzzy-FMEA (FFailure Mode and Effects Analysis), FTA (Fault Tree Analysis) dan BTA (Bowtie Analysis).Dari hasil analisa dan pembahasan bahwa dengan Metode Fuzzy-FMEA diperoleh Kode A20 Sistem Pengelolaan Burner nilai FRPN 8.012, Kode A1 Ruang Bakar Terintegrasi dengan cerobong asap nilai FRPN 7.822, Kode A8 Unit Pemulihan Panas Limbah (WHRU) FRPN 7.712.Menggunakan Metode Fault Tree Analysis (FTA) diperoleh Kegagalan kontrol burner pada sistem pengelolaan burner dengan probabilitas 0.003180233, Process upset dari ruang bakar yang terintegrasi dengan cerobong asap dengan probabilitas 0.002995017, Hot oil overflow dari Coil tube system unit pemulihan panas limbah (WHRU) dengan probabilitas 0.004991480.Menggunakan Metode Bowtie Analysis (BTA) top event Kegagalan Kontrol Burner Gambar IV.20 terdapat 4 penyebab/threat di sisi kiri dan 4 dampak/consequence di sisi kanan, top event Process Upset Dari Combustion Chamber Gambar IV.21 terdapat 4 penyebab/threat di sisi kiri dan 4 dampak/consequence di sisi kanan, top event Hot Oil Overflow Dari Coil tube Gambar IV.22 terdapat 5 penyebab/threat di sisi kiri, dan 5 dampak/consequence di sisi kanan.

Thermal Oxidizer (TOX) is a device that functions to burn hazardous waste gas (waste gas) which has a high toxic content into flue gas with a low toxic concentration. So as to maintain the continuity of the process, then to minimize the risk level of risk identification methods, root causes of problems and appropriate and effective mitigation steps. Therefore in this study, risk analysis on the operating conditions of the Thermal Oxidizer unit using the Fuzzy-FMEA (Failure Mode and Effects Analysis), FTA (Fault Tree Analysis) and BTA (Bowtie Analysis) methods. From the results of the analysis and discussion that with the Fuzzy-FMEA method obtained Code A20 Burner Management System FRPN value 8.012, Code A1 Integrated Burning Room with chimney FRPN value 7.822, Code A8 Waste Heat Recovery Unit (WHRU) FRPN 7.712. Using the Fault Tree Analysis (FTA) method obtained Burner control failure in the burner management system with probability 0. 003180233, Process upset of the combustion chamber integrated with the chimney with probability 0.002995017, Hot oil overflow from the Coil tube system of the waste heat recovery unit (WHRU) with probability 0.004991480.Using the Bowtie Analysis Method (BTA) top event Burner Control Failure Figure IV.20 there are 4 causes / threats on the left side and 4 impacts / consequences on the right side, top event Process Upset From Combustion Chamber Figure IV.21 there are 4 causes / threats on the left side and 4 impacts / consequences on the right side, top event Hot Oil Overflow From Coil tube Figure IV.22 there are 5 causes / threats on the left side, and 5 impacts / consequences on the right side.
