Abstract

Telah dilakukan penelitian tentang pemodelan anomali magnetik berbentuk prisma menggunakan metode algoritma genetika. Penelitian ini bertujuan untuk memodelkan anomali magnetik total dengan pendekatan benda anomali berbentuk prisma dua dimensi. Anomali magnetik total dihitung berdasarkan parameter model berupa posisi prisma pada bidang horizontal (Xo), kedalaman prisma dari permukaan (d), panjang prisma dari permukaan (D), lebar prisma (b), dip ( ), dan suseptibilitas magnetik (k). Pengujian metode algoritma genetika dilakukan terhadap data anomali magnetik total yang diperoleh dari hasil pengukuran di lapangan. Dari hasil pemodelan pada data A diperoleh koefisien korelasi sebesar 0,9870 dengan nilai kesalahan kuadrat rata-rata (RMSE) sebesar 26,9006, sedangkan hasil pemodelan pada data B diperoleh koefisien korelasi sebesar 0,8590 dengan kesalahan kuadrat rata-rata (RMSE) sebesar 7,4398.
