Abstract
Metode Maegnetotellurik (MT) dapat digunakan untuk
mencitrakan resistivitas bawah permukaan yang dalam.
Resistivitas bawah permukaan ini didapat melalui proses inversi
data MT. Pada penelitian ini, inversi data MT untuk
menghasilkan resistivitas 1D menggunakan algoritma
Multiobjektif Dragonfly untuk meminimumkan error antara data
resistivitas semu dan fase perhitungan dengan data pengukuran.
Algoritma ini telah diuji pada data sintetik dan data lapangan.
Hasilnya ialah algoritma multiobjektif dragonfly dapat
digunakan untuk menentukan resistivitas bawah permukaan
dengan akurat dan sesuai kondisi litologi bawah permukaan.

Magnetotelluric Method (MT) is used for imaging
resistivity of subsurface. The resistivity is obtained by inversion
process of MT data (apparent resistivity and phase). In this
research, inversion of MTdata is used to obtain the 1-D resistivity
using Multiobjective Dragonfly algorithm to simultaneously
minimize root mean square error of observed and calculated MT
data. This algorithm has been tested both synthetics and field
data. The result is Multiobjective Dragonfly algorithm can be
used to accurately determine the resistivity of subsurface and in
accordance with the condition of local lithology.
