Abstract

North Sulawesi is in a complex tectonic interaction which is the relative movement of three Eurasian macro plates, the Pacific plate, the Philippine plate, and the Maluku Sea microplate. The active tectonic movement results in high earthquake activity in the region of North Sulawesi and its surroundings. This results in the importance of accurate earthquake parameter information, one of which is by conducting research on local wave velocity. The purpose of this study is to determine the velocity of 1D P waves and relocate the earthquake hypocenter and determine the correction stations in North Sulawesi and surrounding areas with coordinate boundaries 0.17166°S- 2.742781°N and 119.5212°E- 125.5067°E using the Couple Velocity-Hypocenter method with Velest software. The results of simultaneous inversion processing are carried out until the 50th iteration which obtains the wave velocity fluctuates at several depths but in general, the denser layers of the earth's compilers will increase the wave velocity, the improvement of the RMS from an average of 1.71 to 0.49 and the correction of the stations obtained is at intervals of 0.39 to 20.91.

Abstract

North Sulawesi is one of the regions with a large potential of geothermal manifestations, wrongly located in Toraget Village, District of Langoan, Minahasa Regency, where there is a geothermal manifestasion . The purpose of this study was to study the mineral composition using SEM-EDX and FTIR in Toraget Village, Langoan District, Minahasa Regency. Based on the results of research conducted in Toraget Village, Langoan District, Minahasa Regency has a mineral composition in sample 1 namely Oxygen (O), Silica (Si) with percentages of weight are 61.32% and 38.68% and atomic percentages respectively 73.57% and in sample 2 hot springs have elemental content that is Oxygen (O) with percentage weight and percentage atomic 100%. For the functional cluster of rock sample 1 which contains C-O Ester, C-H Alkene, Aromatic C=C Alkene, and sample 2 contains C-O Esters, C-H Alkene, Aromatic C=C Alkene.

Abstract

Indonesia is a country that has 40% of the world's geothermal potential, but only 3% was used.Research to determine the potential for geothermal distribution in the southern part of MountTampusu is by taking data directly using a thermometer, the purpose of this research was todetermine the temperature distribution at a depth of 0 cm, 30 cm, 60 cm, 90 cm by mapping. Thedata obtained is primary data, then entered into Microsoft Excel. In Microsoft Excel analyzed of themaximum, minimum and average temperatures. Then from the temperature data in the form oftemperature contours based on depth by using surfers 11. From the results of data processing usingsurfers, it was found that the temperature distribution in the southern part of Mount Tampusu variedin value, in the morning at depth 0 cm, 30 cm, 60 cm, 90 cm has value 23.5775°C, 22.67°C,23.315°C, 24.1025°C, daytime at depth 0 cm, 30 cm, 60 cm, 90 cm has value 27.5675°C,24.2525°C, 24.1825°C, 24.6925°C, in the evening at depth 0 cm, 30 cm, 60 cm, 90 cm has value24.5525°C, 24.3525°C, 24.2825°C, 24.605°C. The temperature pattern in the southern part ofMount Tampusu has a perpendicular pattern and slightly spreads to the northwest.
