“…Remote sensing techniques are ideal for use in the initial investigation of geothermal potential. The results of remote sensing data processing can then interpret the earth's surface conditions and the distribution of soil temperature which can be used to identify potential geothermal locations [10,11]. One of the remote sensing data used for geothermal identification is Landsat 8.…”

In Indonesia is the Iyang-Argopuro Volcano Complex. The Research uses remote sensing methods and gravity methods conducted to study thermal anomalies and subsurface structures using Data images of Landsat 8 satellite and a data gravity of GGMPlus satellite. Moreover, the study aims to estimate the number of hoisting manifestations of the earth's heat at the compound of the Iyang-Argopuro volcano. Landsat 8 satellite image data is a spectral band (band 1-9) and a thermal band (band 10 and 11). The data was done in radiometric corrections, radiance correction, and reflex corrections, and was thus obtained a value of ground surface temperature (LST). The data was done in radiometric corrections, radiance correction, and reflectance corrections, to get an LST value. Processing data gravity of GGMPlus satellites with a bouguer correction, terrain corrections up to get a Complete Bouguer Anomaly (ABL) value. Furthermore, the ABL value consisting of regional and local anomalies is separated using an upward continuation filter to obtain local anomaly values. The results obtained from this study are five points of geothermal manifestation locations in the Iyang-Argopuro Volcano Complex which are located in the northern, central, southern and eastern parts. Manifestations in the northern, central, and northeastern parts have ground surface temperatures of 24-31 ̊C. While manifestations in the central and eastern parts have a surface temperature of land 21-31 ̊C. The high ground temperature values at the five locations were associated with low gravity values ranging from -20 mGal to -10 mGal. The low gravity value is assumed to have a rock structure with a low-density value. Low-density rock structures have the possibility of an outflow zone causing the soil surface temperature to be relatively high.

“…Beberapa penelitian menyebutkan bahwa teknik penginderaan jauh sangat ideal digunakan dalam penyelidikan awal di daerah eksplorasi panas bumi [10]. Hasil dari pengolahan data penginderaan jauh dapat menginterpretasikan kondisi geomorfologi dan sebaran temperatur tanah serta keberadaan titiktitik manifestasi potensi panas bumi yang selanjunya dapat digunakan untuk mengidentifikasi lokasi survei lanjutan dan penentuan batasan daerah prospek panas bumi [11].…”

Abstrak. Dalam menentukan daerah prospek panas bumi, pemetaan permukaan diperlukan untuk menentukan titik atau area prospek yang dapat dikaji bawah permukaannya. Pemetaan permukaan bumi dapat dilakukan menggunakan citra satelit landsat 8. Penelitian ini dilakukan untuk memetakan struktur , temperatur permukaan tanah dan batuan permukaan. Hasil yang didapatkan dikorelasikan dengan geologi. Data citra yang digunakan pada penelitian ini adalah citra satelit landsat 8 dengan band 4, band 5, band 7 dan band 11. Untuk memperoleh informasi struktur bawah permukaan dilakukan komposit pada band 4, band 5, band 7. Untuk menentukan temperatur permukaan digunakan band 11 yang dikoreksi atmosfer terlebih dahulu untuk menghilangkan pengaruh atmosfer dalam wilayah termal. Untuk menentukan titik batuan teralterasi maka dilakukan komposit band 7, band 4, band 2. Hasil yang didapatkan adalah struktur bawah permukaan, temperature permukaan dan batuan permukaan tanah.Kata Kunci : Citra Satelit 8 , struktur, alterasi, temperatur permukaan tanah Abstract. Research has been conducted with the aim of mapping structure, surface temperature, surface rock and geological analysis to determine the geothermal prospect of Songgoriti, Batu and surrounding areas with Landsat 8. On this research, Data are bands 4,5,7 and 11. To structural information, a composite of 4,5.7 seconds was used to obtain the thermal satellite used by band 11 corrected bands to eliminate atmospheric influence in the thermal region. To determine the point of alteration of rocks then made a composite band 7, band 4, band 2. The result is a structural map, surface temperature map and surface rocks.
