Abstract

Volcanoes are mountains that are formed as a result of eruption material accumulating around the center of an eruption or a mountain formed from a magma eruption. Volcanoes are only found in certain places, namely in the mid-ocean ridge, at the point where two plates of the Earth's crust meet, and at hot spots on the earth where magma is released, on continents and in oceans. Indonesia is a country with active volcanoes formed due to subduction zones between three tectonic plates, namely the Eurasian plate, the Indo-Australian plate and the Pacific plate. The location of the research was carried out in the Soputan Volcano Area, by taking two samples, namely two different rock types in the study area. This study aims to determine the elemental composition of the rock and rock mineral types in Soputan Volcano. Using SEM-EDX and FTIR. The results of the research on sample 1 of the EDX device were Bromine, Silica, Tungstate, Gold, Molybdenum, Calcium, Iron, Iterbium, Lutetium. And in sample 2 of the EDX tool, namely Aluminum, Silica, Iron, and Cobalt, and the results of field research that has been conducted using SEM-EDX and FTIR, it can be concluded that: The elemental composition of volcanic rock in Soputan volcano has Br, Si elements. , W, Au, Mo, Ca, Fe, Yb, Lu, Al, Co. As well as the type of rock minerals, basalt in sample 1 and sample 2 is andesite.

Abstract

Pine Forest is one of the tourist attractions in Lahendong Village, which has geothermal manifestations in the form of hot springs, which shows that the area has geothermal potential. The purpose of this study was to determine the type of fluid manifested by hot springs in the Pine Forest using geochemical methods. The results of this study indicate that the temperature at the manifestation is 40°C while the degree of acidity of the pH of hot water has a value of 4 which indicates the acidity level of hot water is acidic. The type of fluid that exists in the manifestation area of hot water in the Pine Forest is the type of fluid sulphate water and sulfate water is a fluid that is formed at shallow depths and is formed as a result of the condensation process of geothermal gas towards near the surface. This is because the results of chemical analysis show that the element SO4 is the most dominant element and contains SO4 gas. Hot water that has a sulfate type is water that is formed at shallow depths and is formed as a result of the process of condensing geothermal gas towards near the surface. The geothermal gas with gas content (water and carbon) is basically dissolved in the fluid content which is located in the deep zone but separated from the chloride water. Sulphate water is usually at the boundary and not far from the main upflow zone.

Abstract

Pine Forest is a mountain located in North Sulawesi Province, Indonesia. The surface temperature around the Pine Forest changes from year to year. Whether the changes occurred significantly or only slightly, it certainly had an effect on the vegetation around the mountain. The purpose of this study was to determine the surface temperature and vegetation in the geothermal manifestation area around the Pine Forest based on the Remote Sensing Method. By using remote sensing can calculate the vegetation and surface temperature in the Pine Forest. In this study, the analysis uses Landsat 8 satellite imagery in 2020. According to the results, vegetation is negatively correlated with surface temperature, which means that 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

This study aims to simulate and analyze temperature rise due to the greenhouse effect through a simple experiment and numerical modeling using MATLAB. Two systems—a sealed glass jar (simulating a greenhouse gas-trapping atmosphere) and an open jar (control)—were exposed to sunlight for 30 minutes, with temperature recorded at 5-minute intervals. Experimental results showed that the sealed jar experienced a higher temperature increase (24°C to 28.5°C) compared to the open jar (24°C to 28°C), demonstrating heat trapping. Data were analyzed using MATLAB's Curve Fitting Toolbox for regression modeling and graphical visualization. Numerical simulations exhibited strong consistency with experimental data, confirming the model's accuracy in predicting temperature trends. The study concludes that MATLAB is an effective computational tool for simulating physics phenomena related to global warming while highlighting the urgency of environmental mitigation. These findings can serve as a foundation for developing applied physics experiments or small-scale climate models.
