The study is motivated by the importance of paying attention to democratic interaction among students in order to prepare them with the 21st-century competencies they need to possess. This research aims to understand the democratic interactions across different levels of students through Thematic-Explorative-Democratic Learning in physics at Tumimperas Waterfall. The research method used is descriptive qualitative, with the subjects of the study being two groups of students from the Physics Department at Manado State University. Data were collected through observation and peer assessment based on eight indicators of democratic interaction. Data were analyzed through data collecting, reduction, display, and classification. The results showed that students from various levels were able to interact democratically with scores ranging from good to very good. This democratic interaction aids in the development of critical thinking skills, collaboration, effective communication, and social responsibility. Thus, Thematic-Explorative-Democratic Learning at Tumimperas Waterfall can be considered an effective learning activity in developing 21st-century competencies in students

The energy crisis is one of the major problems facing the world today, especially electrical energy. Supercapacitors are an alternative solution as an electrical energy storage divais. In this study, batik kawangkoan peanut shell samples have been successfully modified into activated carbon as a supercapacitor electrode. The carbonization process is given a carbonization temperature treatment of 350oC, 400oC, 450oC, 500oC, 550oC which is activated using a 7 M KOH solution by heating in a furnace at 750oC to produce a voltage of 0.966 V, 1.273 V, respectively, 1.295 V, 1.325 V, 1.654 V and currents of 18.56 mA, 23.43 mA, 26.47 mA, 30.53 mA, 48.24 mA which shows that there is a change in the value of current and voltage in supercapacitors, and the best sample is in the sample with 550oC carbonization temperature treatment. Thus, it can be concluded that carbonization temperature has an influence on the current and voltage characteristics of supercapacitor electrodes.

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.

This study aims to determine the effectiveness of using the problem posing learning model with an environmental approach to learning outcomes. This research was conducted at SMA N 1 Likupang, North Minahasa. In this study using one group pretest-posttest design. The instrument in this study used a cognitive description test in the form of a pre-test and posttest to measure student learning outcomes. The sample in this study was class X MIA II which amounted to 20 students. The average pretest score is 50 and the average posttest score is 84.25, the results of the data processing show an increase. The results of the N-Gain Test score 0.7791 which shows that there is an increase in student learning outcomes in the high category with a percentage of 77.90%. Based on this data, it can be concluded that the Problem Posing Learning Model with an Environmental Approach can improve student learning outcomes on the material of Newton's Law II

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

The current energy needs are increasing due to technological advances and the increasing number of technology users. So, to solve this problem, it is necessary to make major changes and energy renewal by using alternative energy. One of the utilization of alternative energy is energy storage devices such as supercapacitors. In this study, a test was carried out on the activation of coconut stem waste as a supercapacitor electrode with variations in KOH electrolyte, namely 6M, 7M, 8M which produced voltages of 1.254 V, 1.187 V, 1.105 V and produced currents of 87.2 mA, 46.52 mA, 25.38 mA respectively. Based on the results of the study, it showed a decrease in the concentration of electrolytes 6M, 7M, 8M. So it can be concluded that different electrolytes have a significant effect on the voltage and electric current values â€‹â€‹produced by the supercapacitor electrodes.
