Abstract

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.

Abstract

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.

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.
