Abstract
Manajemen Risiko merupakan keutamaan perusahaan dalam menjalankan kegiatan produksi. Keselamatan dan keamanan dalam pabrik sangat penting untuk diperhatikan terutama terhadap alat dan instrument yang berbahaya seperti furnace. Pada tugas akhir ini dilakukan analisis untuk mengetahui risiko bahaya yang bisa terjadi pada furnace. Risiko bahaya yang terjadi dapat dianalisis menggunakan metode HAZOP sehingga sistem dapat dianalisis bahayanya berdasarkan node yang ada pada equipment lalu dapat dihitung LOPA untuk mendapatkan Safety Integrity Level (SIL) atau tingkat lapisan pelindung yang diperlukan equipment. Berdasarkan penelitian yang dilakukan pada tugas akhir ini, furnace memiliki risiko bahaya tinggi (high risk) pada node 5 yaitu pada 86-FT-207A. Perhitungan dengan metode LOPA didapatkan nilai NR sebanyak satu impact event, nilai SIL 0 sebanyak enam impact event dan SIL 1 sebanyak tiga impact event. SIL 1 memiliki arti bahwa lapisan pelindung dari impact event belum sepenuhnya dapat mengurangi risiko. Setelah itu dipetakan tiap resiko menggunakan FLOPA agar memudahkan membaca bagi operator. Dari perhitungan baik manual maupun dengan FLOPA, diketahui bahwa lapisan perlindungan yang ada telah cukup. Tetapi tetap diperlukan konfigurasi SIS agar dapat mereduksi SIL 1 menjadi SIL 0.

Risk Management is the company's priority in carrying out production activities. Safety and security in the factory is very important to pay attention to, especially for dangerous tools and instruments such as furnaces. In this final project, an analysis is carried out to determine the risk of danger that can occur in the furnace. Hazard risks that occur can be analyzed using the HAZOP method so that the system can be analyzed for hazards based on existing nodes on the equipment and then LOPA can be calculated to get the Safety Integrity Level (SIL) or the level of protective layer required by the equipment. Based on the research conducted in this final project, the furnace has a high risk of danger at node 5, namely at 86-FT-207A. Calculations with the LOPA method obtained NR values for one impact event, SIL 0 values for six impact events and SIL 1 for three impact events. SIL 1 means that the protective layer from the impact event has not fully reduced the risk. After that, each risk is mapped using FLOPA to make it easier for operators to read. From both manual and FLOPA calculations, it is known that the existing layer of protection is sufficient. However, SIS configuration is still required in order to reduce SIL 1 to SIL 0.
