Abstract

Geothermal is one of the alternative energy sources that are classified as new and renewable (new and renewable). This is because geothermal energy sources are still relatively new and are said to be renewable because production waste in the form of water is re-injected and produces a recycle process that allows sustainability. The process of exploration, exploitation and production does not produce toxic gas emissions. In terms of prospects, geothermal itself is a promising energy in the future because the source is heat from within the earth that will never run out. One of the areas in North Sulawesi that has the potential for geothermal project development is located in the Tomohon area, North Sulawesi Province. Based on the preliminary survey that has been carried out, at this location found manifestations in the form of hot springs located in the Pine Forest. The purpose of this study was to determine the type of fluid and functional groups of molecules manifesting hot springs in the Tomohon pine forest tourism area. Analysis of the ion content in the fluid using spectrophotometer characterization, and analysis of molecular functional groups using FTIR (Fourier Transform Infra Red) spectroscopy. The results showed that the type of fluid manifestation of the hot springs in the Tomohon Pine Forest Tourism Area has the type of bicarbonate (HCO3). Analysis of functional groups of fluid molecules in the manifestation of hot springs in the Tomohon Pine Forest Tourism Area has functional groups C=O, C≡C and O-H.

Abstract

Geothermal is one of the natural resources that has great potential to be used as a renewable energy. The existence of geothermal resource on the surface is reflected by the presence of the geothermal manifestations on earth surface. This research was conducted to map the shallow subsurface temperature and determine the temperature gradient pattern of the geothermal manifestation in Noongan Tiga Village, Minahasa. This research uses observation method by measuring the temperature at the depth of 3 cm, 9 cm, and 15 cm in the morning, daytime, and the afternoon at 10 different points. The results showed that in that in the morning the temperature average reached 42,03 0C at the depth of 3 cm, 50,09 0C at the depth of 9 cm, and 60,26 0C at the depth of 15 cm. In the daytime, the temperature average rises to 59,2 0C at the depth of 3 cm, 66,01 0C at the depth of 9 cm, and 76,16 0C at the depth of 15 cm. While in the afternoon the temperature average reaching 41,28 0C at the depth of 3 cm, 49,46 0C at the depth of 9 cm, and 59,38 0C at the depth of 15 cm. The temperature gradient obtained shows an increase in temperature where the deeper you go, the temperature increases, with a linear temperature gradient pattern to the northeast.

Abstract

The increasing population of the world's population results in the need for energy to continue to increase, therefore the Indonesian government develops energy outside of fossil fuels, one of which is geothermal. Geothermal is one of the alternative energy source that is relatively new and renewable and can be renewed because production waste in the form of water is re-injected and produces a recycle process that allows sustainability. Geological surveys, geochemical surveys, and geophysical surveys are characterizations that need to be carried out in describing geothermal potential. The purpose of this study was to determine the type of fluid and molecular functional groups of hot springs in Tempang Village, Minahasa Regency. With the geochemical method using a spectrophotometer and FTIR (Fourier Transform Infra Red) spectroscopy, it is known that the type of fluid in the hot springs in Tempang Village is Bicarbonate (HCO3) type with a content of 69 mg/L and the molecular functional group is O-H and C=O.

Abstract

The utilization of renewable energy has become a major focus in an effort to reduce dependence on fossil energy sources and reduce negative impacts on the environment, making it important to increase the use of clean and renewable energy. One of the biggest challenges in the application of renewable energy is efficient and sustainable energy storage. In this case, supercapacitors have proven to be a solution as an efficient and sustainable energy storage device. In this study, water hyacinth biomass material was tested as a supercapacitor electrode which was influenced by variations in Na2SO4 electrolyte, namely 1M, 2M, and 3 M, which produced voltages of 1.037 V, 1.404 V, and 1.647 V respectively and electric currents of 18.56 mA, 23.32 mA, and 32.34 mA. From the results of this study, it was found that the sample with an electrolyte concentration of Na2SO4 3 M had higher voltage and amperage values, which amounted to 1.654 V and 32.34 mA due to the greater number of Na+ and SO42- ions in the electrolyte. So it can be concluded that the variation of Na2SO4 electrolyte concentration of 1 M, 2 M, and 3 M results in an increase in the value of voltage and electric current produced by supercapacitors.
