Abstract
Naphtha Hydrotreater Unit (NHT) merupakan salah satu proses untuk mengolah heavy naphtha dengan menggunakan prinsip hydrotreating sehingga akan menghasilkan naphtha yang memenuhi untuk menuju proses selanjutnya. Salah satu equipment yang terdapat pada NHT yaitu charge heater (82-F-201) dan reboiler heater (82-F-202). Dalam menjalankan prosesnya diperlukan tingkat keamanan yang baik serta mengetahui potensi bahaya yang terdapat pada plant. Hasil penelitian yang dilakukan dengan menggunakan metode HAZOP menunjukkan bahwa 82-F-201 memiliki persentase 29,41% high risk sedangkan 82-F-202 dengan 45,45% high risk. Safety intrumented system (SIS) pada kondisi aktual untuk 82-F-201 dan 82-F-202 masing-masing memiliki SIL 0. Pada rancangan SIS untuk 82-F-201 dan 82-F-202 diperoleh hasil SIL 2 dimana sesuai dengan target SIL perusahaan. Untuk nilai LCC rancangan diperoleh nilai USD 477370 untuk 82-F-201 dan USD 320430 untuk 82-F-202. Pada masing-masing section jenis teknologi paling optimum yang digunakan umumnya yaitu teknologi A dengan smart transmitter dan air operated valve. Serta vote arsitektur paling optimum beragam yaitu menggunakan 1oo1, 1oo2, 1oo3, dan 1oo4. Dengan demikian evaluasi SIS yang perlu dilakukan yaitu melakukan perawatan instrumen secara rutin dan mengganti vote arsitektur pada tiap instrumen sehingga dapat dikurangi nilai failure rate dengan melakukan perawatan.

Naphtha Hydrotreater Unit (NHT) is one of the processes to process heavy naphtha by using the principle of hydrotreating, so that it will produce naphtha which meets the requirement for the next process. One of the equipment contained in the NHT is a charge heater (82-F-201) and a heater reboiler (82-F-202). This hydrotreating process require a good level of security and knowing the potential hazards contained in the plant. The results of research conducted using the HAZOP method indicate that 82-F-201 has a percentage of 29,41% high risk while 82-F-202 has 45.45% high risk. The safety intrumented system (SIS) in the actual conditions for 82-F-201 and 82-F-202 each had SIL 0. In the SIS design for 82-F-201 and 82-F-202 the SIL 2 results were obtained which corresponded to target company SIL. For the LCC design value, the value of USD 477370 for 82-F-201 and USD 320430 for 82-F-202 are obtained. In each section, the most optimum type of technology used is technology A with a smart transmitter and air operated valve. As well as the most optimum vote architecture varies, using 1oo1, 1oo2, 1oo3, and 1oo4. Thus the evaluation of SIS that needs to be done is to perform maintenance of the instrument routinely and replace the vote architecture on each instrument so that it can be reduced by the value of the failure rate by performing maintenance.
