Abstract

To meet the urgent future energy needs, and the demand for sustainable and renewable energy resources continues to increase, electrical energy storage devices such as supercapacitors are an alternative for biomass-based electrical energy utilization. In this study, water hyacinth samples have been successfully modified into activated carbon from KOH and NaOH activators as supercapacitor electrodes. Chemical activation process using KOH solution concentrations of 3 M, 5 M, 7 M and NaOH 3 M, 5 M, 7 M, with physical activation using a furnace at 750oC produces a voltage with each concentration of 3 M, 5 M, and 7 M KOH of 1.235 V, 1.637 V, 1.715 V current 12.01 mA, 9.59 mA, 6.76 mA and 3, 5 M, and 7 M NaOH 1.012 V, 1.516 V, 1.625 current 10.59 mA, 9.53 mA, 6.09 mA which shows that there is a difference in the value of voltage and electric current in supercapacitor electrodes, with KOH samples with concentrations of 3 M, 5 M, and 7 M, overall KOH is better than the type of activator NaOH. So it can be concluded that the type of activator has a characteristic influence on the voltage and electric current in supercapacitor electrodes

Abstract

Physics learning in university is often theoretical and lacks a contextual approach, making it difficult for students to understand concepts in depth. Thematic-Explorative-Democratic Learning (TED) is an approach that emphasizes the exploration of real experiences and democratic interaction. This study aims to determine the results of physics concept exploration and democratic interaction of students through the application of TED learning themed traditional games cenge-cenge. The research method used is descriptive qualitative with data collection techniques through observation, exploration sheets, and democratic interaction assessment sheets. The results show that students are able to identify various physics concepts such as Newton's laws, gravity, parabolic motion, rigid body equilibrium, friction, and momentum. Democratic interaction is seen from active collaboration between students across semesters. It is concluded that TED learning based on traditional games is effective in improving contextual physics understanding as well as student participation and cooperation.

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.

Abstract

In today's modern life, electrical energy has become a primary need that cannot be avoided. Supercapacitors are a new breakthrough in the field of energy storage, where supercapacitors have a higher power density than batteries and have a higher energy density compared to conventional capacitors. This study characterized the structure of coconut fiber activated carbon activated with NaOH with varying concentrations of 3 M and 5 M. Testing on X-ray Diffraction (XRD) showed the absence of sharp peaks which confirms that this activated carbon is amorphous, meaning carbon that is not arranged in a perfect crystal. Meanwhile, the FTIR test of 3M Coconut Fiber Activated Carbon confirmed many oxygen groups (C-O 1044 cm-1 1044 cm-1, strong aromatic peak (1567 cm⁻¹), more polar surface, and higher concentration of 5M deoxygenation (C–O weakens/disappears), more graphitized aromatic structure, higher porosity (CO₂ adsorbed ↑), more nonpolar surface. Meanwhile, coconut fiber charcoal (without activation) confirmed the main chemical components of coconut fiber, especially dominant cellulose, lignin and hemicellulose.

Abstract

Central Sulawesi is located between the boundaries of tectonic plates which are interconnected with one another. Some tectonic plates are located near Central Sulawesi, including the Indo-Australian plate, the Pacific plate, and the Eurasian plate. The interaction of these plates causes the formation of subduction and fault lines as locations that have the potential to become the center of an earthquake. Earthquakes at scale specific strength can cause infrastructure damage and fatalities. This has led to the importance of erecting earthquake resistant buildings based on the characteristics of ground motion which is Peak Ground Velocity and Ground Motion Prediction Equation method. The purpose of this study is to see the pattern of the relationship between Peak Ground Velocity and earthquake parameters, make an empirical equation of Peak Ground Velocity predictions and see the gorund motion in the Luwuk area with coordinate 2,5 °LS – 1,5°LU dan 119°BT - 127°BT used the Peak Ground Velocity and Ground Motion Prediction Equation method. The result shows the pattern is directly proportional to the relationship between earthquake parameters and the Peak Ground Velocity, and for the empirical equation obtained is log (PGV) = -3.8873 + 1.026975 x M – 1.34171 x log (R +17).
