Abstract

The effect of different manufacturing processes, such as arc melting, mechanical alloying, and baking, on the crystalline and magnetic behavior of Co2MnSi, Co2MnGa, and Co2MnGe compounds was investigated. Samples of Co2MnSi, Co2MnGe, and Co2MnGa compounds were produced using the arc melting method and the effect of mechanical alloying and annealing processes on the manufactured products was investigated. The results showed that the use of different processes during manufacturing leads to different crystalline and magnetic behaviors of the sample. One of these cases is the correlation of the crystal order with the lattice parameter size in the produced samples and its effect on reducing the saturation magnetization compared to Slater and Pauling's prediction. Also, the change of order induced by the mechanical alloying process in the production of Co2MnSi composition has led to a drop of about 14% in saturation magnetization. The coercivity in the sample produced by arc melting and mechanical alloying in Co2MnGe composition is lower than the expected value, which was attributed to the low magnetic anisotropy of the sample due to the small size of the crystals in this sample, which is compensated in the cooking process. For example, performing the grinding process before baking leads to a change in the crystal order and, consequently, to a decrease in the saturation magnetization of the sample. The final baking increases the size of the crystals and reduces the strain. The sample obtained from grinding after arc melting had more coercivity than the other two samples due to having smaller crystals.

Abstract

This study aims to determine whether or not using the phyphox application affects student learning outcomes in terms of prior knowledge and student responses. This research was conducted in high school, using a quasi-experimental research method (quasi-experimental). The design model of this research was pre-test and post-test using a randomized design by giving an initial test before learning and a final test after learning. In this study, two classes were involved as representatives of the experimental class, given the behavior of learning hypothetical deductive thinking strategies using Phyphox media. In contrast, the control class was used as a comparison of Phyphox tools. The results showed that the experimental class students' learning outcomes were superior to those of the control class. It is shown in the comparison data of the N-Gain value and the results of hypothesis testing. Several covariate parameters also support this research. The percentage change in the practical contribution's value and each parameter's relative contributions shows that the test has improved.

Abstract

This type of research is quantitative research that aims to reduce students' misconceptions through learning a conceptual change model with a cognitive conflict approach (CCM-CCA). The population in this study were students of the Physics Education Study Program, the University of Mataram, and students of the Surabaya State University Science Education Study Program. The sample in this study amounted to 56 second-semester students at both universities, each of which amounted to 29 people. The CCM-CCA used has been validated in Focus Group Discussion (FGD) activities and has been declared valid in content and construct so that it is appropriate to use. Data in this study were obtained through misconceptions tests, observations of conceptual changes and cognitive conflicts, and the interview process. Data analysis in this study used descriptive analysis by looking at the comparison of the percentage of students who had misconceptions before and after being given treatment and analyzing the level of cognitive conflict. The results of this study indicate that the CCM-CCA learning model is effective in reducing student misconceptions. Conceptual changes and cognitive conflicts that occur in students are included in the high and very high categories, and the results of structured interviews show that students experience 4 thought processes while learning CCM-CCA which helps students to change their conceptions from initially experiencing misconceptions to understanding scientific concepts.

Abstract

Based on geological conditions, Indonesia is located between the Indo-Australian plate, the Eurasian plate, and the Pacific plate, making Indonesia prone to tectonic earthquakes. However, since the big earthquake that occurred in Aceh on December 26, 2004, the geological conditions in Sumatra have undergone significant changes marked by stressful situations in the western to southern regions of Sumatra, especially on Sibayak Volcano. This study used data from BMKG and Global CMT, which included magnitude (Mw), depth, earthquake coordinates (longitude and latitude), type of earthquake, strike, dip, and rake. From the analysis using Coulomb 3.3, the highest coulomb stress value of Sibayak Volcano was obtained in 2015 with an average change in coulomb stress of 0.235 bar, shear 0.1909 bar, normal 0.1106 bar. However, the lowest coulomb stress value occurs in 2021 with a moderate shift in coulomb stress of 0.0593 bar, shear 0.0251, normal 0.0849 bar.
