Implementation of Problem Based Learning Model on Rolling Motion Material to Improve Students' Learning Outcomes. Thesis. Department of Physics. Faculty of Mathematics and Earth Sciences. Tondano. 2024. The problem in this study is that physics learning, especially in rolling motion material on an inclined plane, is done theoretically without so that students lack understanding of the material and the use of an inappropriate learning model that has an impact on the average score of students less than sixty-five, in other words insufficient. This study aims to examine the improvement of student learning outcomes with a problem-based learning model. The population of this study amounted to 240 students of class XII SMA Negeri 2 Bitung with a sample of 1 class for the experimental class and 1 class as a control class, each of which amounted to 25 people. This research method is quantitative. Data in this study were collected using pretest-posttest questions. Based on the discussion presented in this study in the previous section, it can be concluded that there is an increase in the learning outcomes of students on rolling motion material on an inclined plane with the Problem Based Learning model at SMA Negeri 2 Bitung.

This research aims to determine the effectiveness of student learning outcomes using PhET simulation material on the principle of continuity for class XI students at SMA Negeri 1 Likupang. This research uses an experimental method with a Two Group design using Post-test Control Group Design. The sample for this research was taken from class XI MIA 1 as an experimental class which was taught using PhET Simulation with a total of 20 students and class The second class is homogeneous and equal. The data taken in this study came from the same post-test in both classes. The average post-test score for the experimental class was 87.35 and the post-test for the control class was 70.7, which means that student learning outcomes in the experimental class were higher than student learning outcomes in the control class. The research results were analyzed using the t-test with a significance level of 0.05, obtaining a value of tcount = 7.763 > ttable = 1.686, so H0 was rejected and H1 was accepted. Meanwhile, for the N-Gain Test, the percent obtained was 76, which is within the effective criteria. From the results of this research it can be concluded that the use of PhET simulations is effective on student learning outcomes in material as continuity.

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 need for energy in everyday life is very important, geothermal energy has the potential to become an energy source for power plants. Indonesia has one of the largest geothermal potentials, because Indonesia is located in the Ring of Fire. One of the provinces known for its abundance of geothermal energy is North Sulawesi. The purpose of this study is to determine the characteristics of this geothermal manifestation. The method used is the Cl-Li-B Geoindicator to determine the outflow zone or upflow zone of a geothermal system. The results of the study show that the manifestation has a temperature of 39â°C with a pH of 6.39 containing a higher chloride (Cl) content than Lithium (Li) and Boron (B), the chloride (Cl) content has a percentage of 82.3529% while for Lithium (Li) has a percentage of 11.7647% and Boron (B) has a percentage of 5.8823%. The data shows that of the three parameters studied, the relatively low B/Cl ratio indicates that the hot spring comes from an old geothermal reservoir and chloride (Cl) has the highest percentage of content, it can be concluded that this manifestation is in the outflow zone
