Abstract
Terminal Penerima CNG (Compressed Natural Gas)
Lombok Peaker adalah fasilitas pendukung penyimpanan CNG
untuk memenuhi kebutuhan gas di Pembangkit Lombok
Peaker. Pembangkit sebesar 150 MW yang mulai beroperasi
tahun 2017 ini, rencanya akan disuplai CNG yang berasal dari
Gresik. CNG tersebut nantinya akan didistribusikan melalui
kapal. Mengingat CNG adalah gas yang bertekanan sangat
tinggi hingga 250 bar, maka potensi bahaya berupa ledakan dan
kebakaran saat proses unloading sangatlah besar jika di
bandingan dengan LNG (Liquefied Natural Gas). Penelitian ini
bertujuan untuk mengidentifikasi bahaya saat proses
unloading, frekuensi terjadi dan dampaknya pada manusia
disekitar fasilitas, dan mengetahui tingkat risiko yang
dihasilkan, serta tindakan mitigasi apabila risiko berada pada
tahap yang tidak diterima. Pengidentifikasian bahaya dilakukan
dengan metode HAZOP (Hazard and Operability) yang
mengacu pada P&ID yang ada. Analisa frekuensi
menggunakan metode FTA (Fault Tree Analysis) dan ETA
(Event Tree Analysis). Analisa Konsekuensi dengan
menggunakan pendekatan fire modelling. Untuk representasi
risiko menggunakan F-N curve yang mengacu standar HKRG
(Hongkong Government Risk Guidelines) dan untuk tindakan
mitigasi menggunakan metode LOPA (Layer of Protection
Analysis). Penilitian ini menghasilkan 4 skenario dengan
tingkat risiko yang tidak dapat diterima yaitu pada CNG
storage untuk skenario jet fire, flash fire, gas dispersion dengan kebocoran medium bore (10-50 mm) dan pada control valve
station untuk skenario gas dispersion dengan kebocoran very
small bore (1-3 mm), sehingga harus dilakukan mitigasi
dengan cara menambahkan IPL (Independent Protection
Layer) berupa temperature alarm, pressure alarm, gas
detector, dan CO2 pada storage area, sedangkan gas detector
pada control valve station.

Receiving Terminal CNG ( Compressed Natural Gas)
Lombok Peaker is a supporting facility for storage of CNG in
Lombok Peaker plants. The 150 MW Power Plant, which
started in 2017, is planned that will be supplied from Gresik.
The CNG will be distributed by the ship. Given CNG is very
high pressure gas up to 250 bar. Then the potential hazard of
explosion and fire when unloading processes are enormous
when compared with the LNG (Liquefied Natural Gas). This
research aims to determine the risk as a result of these hazards
to people around facility. The risk is assessed by identifying
potential hazards in the process of unloading, the frequency
occurs and its impact on humans around the facility. Hazard
identification was conducted using HAZOP (Hazard and
Operability) referring to the existing P&ID. Frequency analysis
using FTA (Fault Tree Analysis) and ETA (Event Tree
Analysis). Consequences analysis was conducted using fire
modelling approach. For the representation of the risk of using
the F-N curve published by HKRG (Hongkong Government
Risk Guidelines) standard is employed and mitigation for
unacceptable risk was conducted using LOPA (Layer of
Protection Analysis). This research resulted in four scenarios
are unacceptable, the first one is CNG storage for the scenario
jet fire, flash fire, gas dispersion with medium bore leak (10-50
mm) and the second one is control valve station for gas
dispersion scenarios with very small bore leak (1-3 mm), so it
must be done by adding the IPL (Independent Protection Layer)
such as temperature and pressure alarms, gas detectors, and CO2 in the storage area, while the gas detector, only the control
valve station.
