Anggraeni, Yulia (2017) Pemodelan 2-Dimensi Data Magnetotellurik Di Daerah Panasbumi Mm. Sarjana thesis, Universitas Brawijaya.
Abstract
Daerah penelitian MM merupakan salah satu daerah panasbumi yang berada di lingkungan vulkanik. Keberadaan daerah panasbumi ini ditandai oleh adanya manifestasi berupa mata air panas dengan temperatur 37.1 - 74. 8ºC. Metode magnetotellurik (MT) telah diaplikasikan untuk mencitrakan struktur tahanan-jenis bawah permukaan di daerah MM. Jumlah titik ukur sebanyak 24 titik dan disusun menjadi 4 lintasan. Pengolahan data MT meliputi: Fast Fourier Transform (FFT), Robust Processing, rotasi data, editing data, dan pemodelan inversi 2-D. Pemodelan inversi ini mengaplikasikan algoritma NonLinear Conjugate Gradients (NLCG) dengan menggunakan perangkat lunak WinGLink. Hasil data MT menunjukkan bahwa nilai tahanan-jenis rendah (ρ ≤ 25 Ωm) diindikasikan sebagai lapisan penudung dengan ketebalan sekitar 1000 meter. Nilai tahanan-jenis sedang (25 < ρ ≤ 100 Ωm) yang berada dibawahnya diindikasikan sebagai reservoir dari sistem panas bumi di daerah panasbumi MM.
English Abstract
MM research area is one of the geothermal areas located in the volcanic area. The existence of geothermal area is characterized by the existence of hot springs with temperature 37.1 - 74. 8ºC. The magnetotelluric (MT) method has been applied to image subsurface structure in the MM area. The number of measuring points are 24 points and arranged into 4 tracks. MT data processing includes: Fast Fourier Transform (FFT), Robust Processing, data rotation, data editing, and 2-D inversion modeling. This inversion modeling applies the NonLinear Conjugate Gradients (NLCG) algorithm using WinGLink software. The result of MT data indicates that the low resistance value (ρ ≤ 25 Ωm) is indicated as a caprock with a thickness of about 1000 meters. The medium resistance value of (25 < ρ ≤ 100 Ωm) below it is indicated as a reservoir of the geothermal system in the MM geothermal area.
