Abstract

Learning in nature is a real form of the educational process. Siau Tagulandang Archipelago Regency which is an area of salak plantation forest that is widely cultivated by the community, but this has an impact on the absence of learning activities, especially regarding physics in the area. So, to realize the process of learning activities in the area of salak plants, an expolarative research was carried out with the aim of identifying the ecosystem and the interactions that occurred and analyzing the effect of the frequency of rain on the infiltration rate. That infiltration is the flow of water into the soil through the soil surface. Infiltration (infiltration rate and capacity) is strongly influenced by various variables, including soil type, slope, density and type of vegetation, soil water content, and rainfall intensity. This research is an expolarative research that emphasizes how students can see the facts/phenomenon they see with the concept of physics. The rate of infiltration and the infiltration capacity of the soil decreases in direct proportion to the increase in the frequency of rain, the more the frequency of rain, the smaller the infiltration that occurs at the same level of rain intensity

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

Indonesia is a country that has the largest geothermal resources in the world which is directly proportional to the number of volcanoes. Indonesia is an archipelagic country located at three junction of active mountain plates, namely the Eurasia, Indo-Australia and Pacific plates. Where Indonesia is also located in an active ring of fire that is associated with active volcanoes in Indonesia. North Sulawesi is one of the provinces in Indonesia which has several active volcanoes, one of which is the object of research is Mount Soputan. This volcano is located in South Minahasa and Southeast Minahasa Districts, North Sulawesi Province. The method used in this research is descriptive method and analysis of geothermal fluid chemical data. Analysis of the ion content in the fluid using a SpectroDirect Photometer. As well as functional group analysis using the FTIR Spectroscopy method (Fourier Transform Infra Red), this method is an infrared spectroscopy method equipped with Fourier transform for its spectrum analysis. Geothermal manifestation fluid in the Old Crater of Mount Soputan Volcano is a bicarbonate type of fluid with an HCO3 content of 479 ppm. The high HCO3 content is thought to be associated with the increase in geothermal fluids containing gas, especially CO2, which then experiences condensation in shallow aquifers.
