IDENTIFIKASI ZONA RESERVOAR PANAS BUMI BERDASARKAN ANALISIS FAULT FRACTURE DENSITY CITRA DIGITAL ELEVATION MODEL ALOS PALSAR DI GUNUNG RAJABASA

نویسندگان

چکیده

Gunung Rajabasa merupakan salah satu lapangan panas bumi di Sumatra yang belum dapat dieksploitasi hingga saat ini. Keberadaan manifestasi daerah ini menjadi petunjuk keberadaan zona reservoar bumi. Penelitian bertujuan untuk mengidentifikasi permeabilitas tinggi berdasarkan analisis Fault Fracture Density (FFD) dan menganalisis keterkaitan antara karakteristik struktur jalur fluida ke permukaan dengan lokasi Metode FFD dilakukan menggunakan Citra Digital Elevation Model (DEM) ALOS PALSAR memetakan kelurusan/lineament berasosiasi patahan maupun rekahan khususnya area manifestasi. Observasi mengkonfirmasi hasil FFD. Arah dominan dari teridentifikasi sebagian selaras searah sistem sesar yaitu arah Barat Laut – Tenggara menunjukkan respons memotong utama. Selanjutnya, cukup signifikan lemah (fracturing) ditunjukkan oleh pola densitas pada upflow Way Belerang, sedangkan outflow mata air Botak berada rendah.

ALOS PALSAR Investigation of Coastal Geomorphologic Mapping

High precision DEM of a tidal-flat is valuable to coastal management as well as pure scientific interest including erosion and sedimentation rate study. Geomorphologic mapping in coastal zone is, however, complicated by the rapid and significant changes on many fluvial forms and poor topographic expression of the landform. Three space-borne SAR systems including ALOS PALSAR, TerrrSAR-X and ERS-...
