Analisis Citra Satelit Landsat 8 Dan Demnas Untuk Identifikasi Prospek Panas Bumi Di Kabupaten Aceh Tengah, Provinsi Aceh

Abstract: Gabungan beberapa analisis pada citra satelit Landsat dan Digital Elevation Model Nasional (DEMNAS) dapat dipergunakan untuk mengidentifikasi indikasi area prospek panas bumi. Analisis dilakukan di Kabupaten Aceh Tengah yang diawali dari informasi keberadaan mata air panas pada peta geologi regional lembar Takengon. Metoda penginderaan jauh seperti metoda Fault and Fracture Density (FFD) dan interpretasi circular feature diterapkan pada citra DEMNAS. Sedangkan metoda Land Surface Temperature (LST) dan Direct P… Show more

“…The DEM data is processed and converted into hillshade images with lighting azimuth angles of 0°, 45°, 90°, and 135°; lighting azimuth angles of 180°, 225°, 270°, and 315°; and a 45° slope of the lighting horizon from the flat plane. The hillshade method is a technique that represents the relief of an area by creating a 3D effect in the image [4].…”

“…Untuk mengidentifikasi keberadaan wilayah prospek panas bumi, beberapa metode dan citra peinginderaan jauh dapat diintegrasikan. Sebagai contoh, Nugraha et al (2021) dan Hakim et al (2017) menggabungkan interpretasi dan analisis citra DEMNAS dengan metode Fault and Fracture Density (FFD) dan Landsat 8 dengan metode Land Surface Temperature (LST) untuk mengidentifikasi keberadaan wilayah prospek panas bumi di Provinsi Aceh.…”

“…mendelineasi adanya indikasi area prospek panas bumi dari sebaran titik atau area yang memiliki anomali suhu. Dari analisis LST akan didapatkan luasan area yang lebih spesifik untuk survey lapangan (Saragih et al, 2015;Nugraha et al, 2021).…”
