Abstract

Mount Tampusu, Minahasa Regency, North Sulawesi has geological conditions that are influenced by the geothermal system. Where the geothermal system has plate movement that affects it, one of which is the convergent plate movement, where two plates collide with each other, resulting in the potential for surface manifestation. This study aims to analyze the surface structure and discharge area or commonly referred to as geothermal manifestations based on the density of straightness and surface manifestations. The structure on the surface was analyzed by lineament density using the FFD method. It is assumed that the fracture or fault is associated with geothermal areas which are mostly difficult to identify because they are covered by surface manifestations. Faults and fractures are the pathways for the movement of hot fluids because they are assumed to be weak fields so that they can be clues to the location of the discharge area or manifestation. Based on the FFD and Remote Sensing Methods collaborated with satellite image data, the surface density and its relationship with the discharge area in the study area were known. Where there are 64.45 straight ridges and valleys in the area with density values ​​ranging from 1.6 to 4.6.

Abstract

North Sulawesi is one of the provinces in Indonesia which has many active volcanoes. Mount Tampusu is an area that has geothermal prospects characterized by geothermal manifestations on the surface, namely hot springs that can contribute to or influence the surrounding rocks making altered rocks within the scope of hot spring manifestations. This study aims to identify the mineral composition and type of alteration rock in the geothermal manifestation area around Mount Tampusu at the study site using SEM-EDX and FTIR methods to determine hydrothermal minerals present in these rocks. The results showed that the mineral composition of altered rock mineral in the geothermal manifestation in Tampusu Village, Remboken District had almost the same content between the rocks in the eyes of the hot springs (where the water came out) and those that were a few meters away from the manifestation, namely Al (Aluminum), Si ( Silica), S (Suklur). With the difference in elemental content, sample 2 has the addition of Al (Aluminum), Si (Silica), MoL (Molybdenum), K (Potassium), Fe (Ferum). And the types of altered rock minerals around the hot spring manifestations in rock samples 1 and 2 are Quartz, Montmonillonitre, Albite, Kaolinite, Gibbsite and Paligorskile.

Abstract

Geothermal manifestation area around Tampusu Mountain is an area surrounded by highlands and lowlands. The existence of the highlands and lowlands allows the fault in the Geothermal Manifestation area around Mount Tampusu. The purpose of this study was to determine the presence of faults in the geothermal manifestation area around Tampusu Mountain based on the Gravity Method. From the results of the study, high bouguer anomaly values ​​are located in the southeast of Tampusu Mountain, with a distribution value of 152.4 - 164.4 mGal (0,001524 – 0,001644 m/s2). Whereas for areas with low bouguer anomaly values are in the southwestern part of Mount Tampusu with values ​​126 - 136 mGal (0,00126 – 0,00136 m/s2). This anomaly variation is probably caused by differences in the density of rocks scattered in the Geothermal Manifestation Area around Tampusu Mountain. Through Bouger Anomaly Value Mapping, it is estimated that the fault in the Geothermal Manifestation area around Mount Tampusu is in the southeastern part of Mount Tampusu which leads to the Northeast, based on the drastic increase in the value of the bouguer anomaly. Fault that is in the Geothermal Manifestation area around Mount Tampusu is classified as a normal fault or fault down.

Abstract

North Sulawesi is one of the areas that has had a fairly high level of seismic activity that has occurred, due to the position of North Sulawesi Island which is located close to the earthquake source. One of the parameters of an earthquake that can be calculated is the earthquake hypocenter.Determining the hypocenter of an earthquake is very important in the world of seismology. The Modified Joint Hypocenter Determination (MJHD) method was carried out for relocation of the earthquake hypocenter. To find out how the results of the Hypocentrum Location Correction using MJHD and the tectonic pattern of the Sulawesi Sea Plate subduction zone. . The results of relocation using the MJHD (Moodifide Joint Hysopcentrum) method showed better and more accurate data quality seen from the residual value (RMS) before (≥1 s) and after relocation (≤1 S). Based on the seimicity results of relocation using the MJHD method, it was found that the earthquake clusters were concentrated at a shallow depth of the range of 20 - 80 km. At a depth of 250 - 300 and a distance of 400 km, there is a seimic gap so that earthquakes rarely occur in this zone.

Abstract

Mount Tampusu is a mountain located in North Sulawesi Province, Indonesia. Mount Tampusu is a mountain flanked by two lakes resulting from volcanic activity, namely Lake Linow and Lake Tondano, also around Mount Tampusu, there are geothermal manifestations such as hot water pools and steamy soils. The surface temperature around Mount Tampusu has changed from year to year. Whether the changes occur significantly or only slightly, surely it affects the vegetation around the mountain. The purpose of this study was to determine the surface temperature and vegetation stress in the area of ​​geothermal manifestation around Mount Tampusu based on the Remote Sensing Method. In this study, the analysis uses Landsat 8 satellite imagery in 2020. The value of surface temperature is obtained from the thermal band processing of Landsat 8 satellite imagery which is then correlated with the vegetation index value obtained from NIR and Red band processing using the correlation method. The results showed that the high vegetation index was in the manifestation area with a value of 0.58. The value of the influence of surface temperature on vegetation -0.70596. A negative value (-) means that the vegetation and surface temperature are inversely correlated. The higher the vegetation, the lower the surface temperature value and vice versa, the higher the surface temperature, the lower the vegetation index.

Abstract

Indonesia is an area that has enormous geothermal potential. In North Sulawesi itself, there are three geothermal locations, including Lahendong, which is the first geothermal field in Eastern Indonesia to produce electricity, then other locations, namely in Tompaso and Kotamobagu. Strategically, Tampusu Mount is located between Tondano Lake and Linow Lake where the two lakes are the largest types of manifestation in North Sulawesi. This manifestation occurs due to the conduction of heat transfer from subsurface rock to surface rock. This study aims to analyze the distribution of temperature at shallow depths to predict the vertical profile of the thermal conductivity of geothermal manifestations in the western part of Tampusu Mount. By using surfur 11 software, it was found that the subsurface temperature distribution at shallow depths was dominated by high temperatures ranging from 30ºC - 43ºC. The lowest temperature ranges from 20ºC - 23ºC and the vertical profile of subsurface heat conduction in the western part of Tampusu Mount is not evenly distributed in each soil layer, because the temperature data obtained varies.

Abstract

Geothermal energy is one of the new and renewable alternative energy sources that are environmentally friendly. Indonesia is one of the countries in the world that has large geothermal reserves. The appearance of a manifestation that appears to the surface indicates the potential for geothermal energy in an area. This study aims to calculate the amount of natural heat loss to determine the potential of speculative resources. Research using natural heat loss calculations is the initial stage in starting geothermal exploration. In the area around Mount Tampusu, Remboken District, Minahasa Regency, North Sulawesi Province, there are surface manifestations that can be seen from the heat loss and speculative resources. This research was conducted by taking data in the field and processing the data using the natural heat loss equation in each manifestation. Based on the research results, the total natural heat loss in manifestations around Mount Tampusu is 17,16 mW and the speculative resources are 171,6 mW.

Abstract

Geothermal energy is one of the alternative energy sources that are environmentally friendly and can help meet the world's energy needs. This requires optimization of geothermal potential, one of which is the area around Mount Tampusu. This study aims to map the distribution of surface temperature around Mount Tampusu using Landsat 8 TIRS imagery and to know the difference in temperature distribution in the area around Mount Tampusu in the time period for taking data from the Landsat 8 TIRS image sensor, to determine the lateral direction of the Heat in the area. The Remote Sensing Method is an effective method used in Geothermal exploration activities through the Ilwis software. The temperature distribution is obtained from resampling the thermal band image of the Landsat 8 satellite (limiting the study area) so that the data is ready to be processed without geometric or radiometric correction processes then converted to get the surface temperature. Based on this research, it can be concluded that the temperature distribution in the area around Mount Tampusu using Landsat 8 TIRS imagery ranges from 15.2 ºC to 32.2 ºC. There was a significant change from 2016 to 2017. Meanwhile, in 2018 the temperature increased to 17 ºC from the previous year.

Abstract

Geothermal is now widely used by several developed countries, there are very many roles of geothermal energy sources, it is necessary to use one of them by utilizing geothermal heat energy itself into electrical energy. In chemical process industry there are a number of processes where a gas and a liquid come into contact with each other and whenever this happens, the gas will introduce a number of liquid particles. This liquid phase carried over to the gas phase can cause a number of problems such as equipment breakdown, process inefficiency etc, and need to be eliminated. Equipment used to remove entrainment is known as a Demister. This study aims to calculate Demister Efficiency throughout 2019 at PLTP Lahendong. Research conducted is to collect data at the Lahendong Geothermal Power Plant Unit-2 and this research uses data processing methods that use applications, namely steam tables and Microsoft Excel. Demister's performance in 2019 for 3 months got 88.90% J results which were influenced by heat loss, pressure and inner diameter, from results obtained after processing it can be concluded that the higher the heat loss value, better the efficiency value, Explains that performance Demister arguably had no problems in a year.

Abstract

Molecules and polymers with a conjugated chain structure such as the organic molecule Disperse Red-19 (DR-19) have delocalized π-electrons along the conjugation chain of the molecule and are easily moved by external electric fields, so that these materials have a large electrical polarizability and exhibit an optical response. which is quite high and very fast. This research was conducted with the aim of studying the surface effect of the Indium Tin Oxide (ITO) substrate in regulating the molecular orientation of the DR-19 film and the effect of the external electric field (E =1.9 MV/m) in regulating the molecular orientation of the DR-19 film. The fabrication method used is the E-PVD method, namely the PVD (Physical Vapor Deposition) method assisted by an external electric field. ) and the electric field E = 1.9 MV/m. The films were analyzed and characterized using X-ray diffraction spectroscopy (XRD). The XRD characterization results showed that with the help of an external electric field of 1.9 MV / m, the resulting film showed an increased structural order, marked by the formation of a crystalline structure in the DR-19 film. The E-PVD method (PVD method assisted by an external electric field E) is very effective in arranging DR-19 molecules so that the molecules can be arranged in an orderly parallel perpendicular to the surface of the ITO substrate.
