Abstract

Indonesia is an area that has enormous geothermal potential. In North Sulawesi itself, there are three geothermal locations, including Lahendong, which is the first geothermal field in Eastern Indonesia to produce electricity, then other locations, namely in Tompaso and Kotamobagu. Strategically, Tampusu Mount is located between Tondano Lake and Linow Lake where the two lakes are the largest types of manifestation in North Sulawesi. This manifestation occurs due to the conduction of heat transfer from subsurface rock to surface rock. This study aims to analyze the distribution of temperature at shallow depths to predict the vertical profile of the thermal conductivity of geothermal manifestations in the western part of Tampusu Mount. By using surfur 11 software, it was found that the subsurface temperature distribution at shallow depths was dominated by high temperatures ranging from 30ºC - 43ºC. The lowest temperature ranges from 20ºC - 23ºC and the vertical profile of subsurface heat conduction in the western part of Tampusu Mount is not evenly distributed in each soil layer, because the temperature data obtained varies.

Abstract

As one of the countries in the tropical region, Indonesia is blessed with various energy resources, one of which is geothermal energy. The existence of geothermal sources on the surface is reflected in the appearance of manifestations to the earth's surface, namely hot springs, fumaroles, etc. This study described the distribution of soil surface temperature to determine the surface temperature and the direction of the surface temperature opening around the Palu Koro Fault, Central Sulawesi. This study used remote sensing methods with thermal infrared channels recorded in 2015, 2017, 2018, 2019, and 2020. The results showed that the ground surface temperature in the geothermal potential area ranges from 31,5501°C - 38,8913°C, and the direction of the temperature opening is in the northwest to the southwest to the Southeast and is getting closer to the Palu Koro Fault.

Abstract

Indonesia is a country that is located on the ring of fire or a volcanic route that is rich in geothermal potential. Geothermal is a renewable resource that is environmentally friendly by utilizing magma from the bowels of the earth. PLTP Lahendong unit 2 is a generating unit located in the city of Tomohon, North Sulawesi, which is capable of generating 20 MW of electrical energy. In a generator one of the most important components is the generator. There are many problems that can affect the work of the generator, for example, the reduced efficiency of the generator. Declining efficiency can affect the electrical energy that is flowing not optimally due to generator losses, and a lot of electricity is lost because of this. Therefore, it is necessary to analyze the efficiency of the generator to see whether or not the effect of the load generated by the generator has an effect on the efficiency of the generator. The results of the study which were then analyzed for 14 days between 09:00 and 21:00 obtained the calculation results which were then analyzed that the lowest load value generated by the generator was 12 MW with generator efficiency of 72% and the highest load value was 19 MW with efficiency of 93% and obtained an average load of 16MW with an efficiency difference of 21%. This shows that the value of the load generated by the generator affects the efficiency of the generator. From the results above, it can be recommended to the related company for further action.

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

Tujuan penelitian adalah untuk mendeskripsikan hubungan antara literasi ekologi dan perilaku ramah lingkungan mahasiswa di kampus. Penelitian ini menggunakan metode kuantitatif dengan desain korelasional, dimana data dikumpulkan melalui survei yang melibatkan sejumlah 34 mahasiswa aktif Prodi Fisika Unima sebagai responden yang dipilih secara purposive sampling. Teknik analisis data yang menggunakan uji statistik parametrik. Temuan penelitian ini menjelaskan bahwa Literasi Ekologi (LE) berperan penting dalam membentuk Perilaku Ramah Lingkungan (PRL) di kalangan mahasiswa. Berdasarkan hasil perhitungan statistik, diperoleh signifikansi, F(1,32) = 4.842, p < 0.035, untuk persamaan regresi, y = 41.534 + (-0.250)x. Koefisien regresi (-0.250) menunjukkan hubungan negatif antara LE dan PRL, dimana peningkatan PRL diikuti dengan penurunan LE sebesar 0.250 unit. Hasil analisis regresi pada nilai (R) sebesar 0.363, menyatakan adanya korelasi moderat antara kedua variabel. Sementara itu, nilai (R2) sebesar 0.131 menunjukkan bahwa hanya 13.1% perbandingan Literasi Ekologi yang dapat dijelaskan oleh Perilaku Ramah Lingkungan, sedangkan sisanya dipengaruhi oleh faktor lain. Sehingga model ini masih belum memadai untuk memprediksi korelasi dengan akurat dan perlu diintegrasikan dengan variabel lain guna meningkatkan kemampuan prediksinya.

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.
