Abstract
Penelitian magnetik telah dilakukan di lokasi manifestasi panasbumi Desa Toro Kecamatan Kulawi Kabupaten Sigi. Tujuan penelitian untuk memodelkan struktur batuan penyusun reservoir panasbumi dan mengestimasi kedalaman reservoir panasbumi. menggunakan data magnetik yang diperoleh di lapangan. Data magnetik yang diperoleh selanjutnya diolah dengan tahapan melakukan beberapa koreksi yaitu koreksi IGRF dan koreksi vairiasi harian guna memperoleh data anomali medan magnet total. Pemodelan kedepan (Forward Modeling) dan Pemodelan kebelakang (Inverse Modeling) digunakan untuk mengetahui batuan penyusun reservoir panasbumi dan kedalamannya. Hasil pemodelan diperoleh bahwa batuan penyusun reservoir berupa batuan yang tersusun atas mineral non magnetik dengan nilai suseptibilitas yaitu: -0,00030125 SI, -0,003413 SI, -0,0084446, SI, -0,05824451 SI dan -0,066777 SI. Reservoir panasbumi berada pada kedalaman 2000-3000 m di bawah permukaan
