Abstract
Dalam beberapa tahun terakhir, pemanasan crude oil di Indonesia dilakukan
dengan memanfaatkan bahan bakar fosil, yang telah diketahui bahwa bahan bakar
fosil merupakan sumber energi tak terbarukan dengan persediaan yang terbatas.
Salah satu metode pemanasan alternatif dapat dilakukan dengan menggunakan
gelombang mikro. Sebuah studi pemodelan pemanasan crude oil dengan sumber
gelombang mikro pada reservoir telah dilakukan. Penelitian ini bertujuan untuk
mensimulasikan propagasi gelombang mikro dan tansfer panas pada reservoir
crude oil. Simulasi perambatan gelombang mikro dan perpindahan panas
divisualisasikan menggunakan Visual Basic 6.0 dengan metode FDTD (Finite
Differrence Waktu Domain). Distribusi crude oil pada seluruh permukaan
reservoir diasumsikan homogen sehingga hasil simulasi disajikan dalam bentuk
dua dimensi. Penelitian ini dilakukan dalam dua tahapan, yaitu simulasi
perambatan gelombang mikro dan simulasi perpindahan panas. Pemanasan crude
oil menggunakan magnetron sebagai generator dari gelombang mikro dengan
frekuensi operasional 2,45 GHz. Gelombang mikro dipandu dalam sebuah pandu
gelombang rectangular dengan modus TM11. Reservoir dengan ukuran 10 x 10 m2
memiliki konstanta dielektrik 4,09 dengan loss dielektrik 0,007 dan crude oil
memiliki konstanta dielektrik dan loss dielektrik masing-masing 2,8 dan 0,15.
Konstanta propagasi gelombang mikro diperoleh berdasarkan karakteristik
reservoir sebesar (0.04 j50.33)m 1 . Simulasi dijalankan menggunakan pulsa
Gaussian dengan variasi parameter waktu dan posisi koordinat. Berdasarkan hasil
simulasi, model distribusi temperatur yang diperoleh adalah (0.0101 ) ( ) 0.2262 t T t e
untuk variasi waktu dan ( 0.03 ) ( ) 531.24 r T r e untuk variasi koordinat posisi.

In recent years, the heating of crude oil in Indonesia is done by fossil fuels, which
has been known that fossil fuels are limited nonrenewable energy sources. One of
alternative heating methods can be performed by using microwaves. A modelling
study of the heating crude oil with a microwave sources fixed in the reservoir has
been created. This study aims to simulate the microwave propagation and heat
tansfer on the crude oil reservoir. The simulation of microwave propagation and
heat transfer visualized by Visual Basic 6.0 with FDTD method (Finite
Differrence Time Domain). The distribution of crude oil on the entire surface of
the reservoir assumed homogeneously so that the simulation results presented in
the two-dimensional form. The study conducted in two phases, namely microwave
propagation simulation and heat transfer simulation. The heating of crude oil
using a magnetron as the microwave generator with operating frequency of 2.45
GHz. The microwave guided by rectangular waveguide with TM11 mode. The
reservoir with size 10 x 10 m2 has the dielectric constant 4.09 and the dielectric
loss 0.007 and the crude oil has the dielectric constant and dielectric loss 2.8 and
0.15, respectively. The constant of microwave propagation (0.04 j50.33)m 1
obtained from characteristics of the reservoir. The simulation run by Gaussian
pulse with the parameter variation of time and position coordinate. Based on the
simulation results, the temperature distribution models are (0.0101 ) ( ) 0.2262 t T t e
for time variation and ( 0.03 ) ( ) 531.24 r T r e for the variation of position
coordinate.
