Abstract
Selalu ada risiko kegagalan (risk of failures) pada setiap
aktivitas pekerjaan yang mengakibatkan efek kerugian (loss).
Salah satu contoh kecelakaan kerja di industri kimia adalah
kebocoran gas. Kebocoran alat-alat industri kimia yang
mengandung gas beracun dapat membahayakan manusia dan
menjadi pencemar lingkungan di sekitar kebocoran. Oleh
karenanya, untuk mengantisipasi jatuhnya korban pada
kecelakaan kerja berupa terjadinya kebocoran gas, dilakukan
simulasi persebaran konsentrasi gas yang keluar dari alat-alat
yang bocor menggunakan software NI LABVIEW agar diketahui
hingga radius berapa dari pusat kebocoran yang merupakan zona
tidak aman. Dari penelitian ini diperoleh hasil bahwa plume
model dan puff model memiliki persebaran gas yang berbeda.
Pada persebaran tanpa building downwash effect, konsentrasi
plume model maksimum pada jarak yang lebih dekat
dibandingkan dengan puff model. Pada plume model, semakin
besar kecepatan angin, jarak searah downwind yang dibutuhkan
untuk mencapai batas aman akan semakin panjang. Sedangkan pada puff model, semakin besar kecepatan angin, jarak searah
downwind yang dibutuhkan untuk mencapai batas aman akan
semakin pendek.

There is always a risk of failure in any work activity that
will result in the effect of losses. An example of work accidents in
the chemical industry is a gas leakage. Leak devices containing
toxic gases can be harmful to humans and the environment in the
vicinity of the leak pollutants. Therefore, in anticipation of
casualties on occupational accidents in the form of a gas leakage,
in this final project we have simulated the concentration
distribution of the gas that comes out from the equipments that
leak using NI LABVIEW software in order to know how far the
radius of leakage from the leakage point which is not safe zone.
From this research showed that the plume model and puff model
have different gas distribution. On the distribution without
building downwash effects, the maximum concentration using
plume model is at closer distance than the puff model. At plume
models, the greater the wind speed, the distance of downwind
direction required to reach the safe limit will become longer.
While the puff models, the greater the wind speed, the distance of downwind direction required to reach the safe limit will be
shorter.
