<![CDATA[Molecular Disperse Red 19 (DR-19) is known as a potential material for photonic device applications such as optical switching and optical data storage. For the application of this photonic device, a good quality film is needed, which has a flat surface, homogeneous thickness, optical stability, and good optical properties.This study aims to examine the effect of the silane substrate surface and the external electric field of 3.3 MV / m in regulating the molecular orientation of the DR-19 film on the silane substrate surface.The fabrication method used is the PVD (Physical Vapor Deposition) method assisted by an external electric field. The film was made on the surface of the silane substrate with the deposition of DR-19 molecules in a variety of external electric fields, namely no electric field (zero field) and the electric field E = 3.3 MV / m. The films were analyzed and characterized using X-ray diffraction spectroscopy (XRD). The results of the X-ray diffraction measurement analysis show that the DR-19 molecules are stacking perpendicular to the surface of the silane substrate, which shows an indication of the strong surfactant effect of the substrate from the hydrogen bonding of the DR-19 molecule with silane substrate. The results of spectroscopic measurements show that with the increase in the external electric field, there is an increase in the effect of aggregation of molecules arranged in an orderly manner perpendicular to the surface of the silane substrate.]]>

<![CDATA[Organic molecules with a conjugated chain structure such as the Disperse Red-1 (DR-1) molecule are known as potential materials for photonic device applications. The aim of this research is to study the surface effect of Indium Tin Oxide (ITO) substrate and the external electric field of 2.6 MV / m in regulating the orientation of the DR-1 film molecules on the surface of the ITO substrate. The fabrication method used is the PVD (Physical Vapor Deposition) method assisted by an external electric field. This method is a modification of the conventional PVD method which is equipped with the addition of an external electric field (E) in the chamber. The film was made on the surface of the ITO substrate with the deposition of DR-1 molecules in a variation of the external electric field, namely zero field and E = 3.3 MV / m. The films were analyzed and characterized using XRD (X-Ray Diffraction) spectroscopy. The X-ray diffraction measurement analysis showed that the DR-1 molecules were arranged in an orderly manner parallel to the surface of the ITO substrate, indicating an indication of the strong surface effect of the ITO substrate from the hydrogen bonding of the DR-1 molecule with the ITO substrate. The results of spectroscopic measurements show that with an increase in the external electric field, there is an increase in the effect of aggregation of molecules arranged in an orderly manner perpendicular to the surface of the ITO substrate.]]>

<![CDATA[Rain is one of the most important climatic elements, but its existence spatially and temporally is still difficult to predict. Apart from being dynamic, the physical processes involved are also very complex. This rainfall uncertainty is getting bigger when climate anomalies occur in the form of El Nino and La Nina. To determine the changes in the el nino index when it rains, in this study a cross-correlation coefficient method with time lag on rain events will be carried out by utilizing data from observational data at the location of the BMKG Sam Ratulangi Meteorological Station. This method used a tool to predict the connection of a data series x (input) with data y (output) in a system. In order to perform a cross-correlation analysis, the two series must be sampled at the same time interval. The secondary data on rainfall and the El Nino index obtained by the researcher have a time interval of half an hour and start from 7 am to 6 pm. The correlation coefficient value of the El Nino index with rainfall in 2015 shows a coefficient value of -0.26467, in 2016 it shows an efficiency value of -0.43383, in 2017 it shows a coefficient value of 0.37771.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>

<![CDATA[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.]]>
