Pemodelan Struktur Bawah Permukaan Formasi Jatibarang Berdasarkan Metode Gayaberat

Metode gayaberat digunakan untuk mengukur variasi percepatan gayaberat yang timbul akibat perbedaan densitas antar batuan bawah permukaan. Penelitian ini dilakukan di daerah Indramayu Jawa Barat dengan tujuan untuk menentukan sebaran anomali bawah permukaan yang dapat menggambarkan Formasi Jatibarang dan kedalaman basement (batuan dasar). Pengolahan data yang dilakukan meliputi koreksi Bouguer, udara bebas, terrain, lintang, pasang surut, dan koreksi apungan. Pemisahan anomali regional dan residual dan pemodelan kedepan. Hasil pengolahan menghasilkan peta anomali Bouguer, peta anomali regiona dan peta anomali residual.
