Abstract

The goal of this project is to create a successful physics e-module for 21st-century skills, utilizing an inquiry model combined with the SETS approach. The method used was the reference approach to Research and Development. This research was Plomp's (1997) development model. Seventy high school students served as the study's subjects. Results of an e-module effectiveness test for collaboration and critical thinking skills make up the data collected for this study. The control class's average score for critical thinking abilities was only 51.15 with a sufficient category, whereas the experimental class's score was 79.38 with a high category for each indicator. The results of the critical thinking skills were also strengthened by conducting the N-gain test. The control class had an n-gain value of -0.37 with a low category, while the experimental class had an n-gain value of 0.58 with a medium category. The experimental class's average student collaboration skills were 84.02 in the very collaborative category, compared to 76.12 in the collaborative category for the control group. These results indicate that the physics e-module is useful in enhancing students' 21st-century abilities.

Abstract

Indonesia is a country prone to earthquake disasters, because Indonesia is located in the collision area between plates, and one of the areas in Indonesia where plate movements often occur is Mentawai. Analysis of waveform data on the 2022 earthquake in the Mentawai region was carried out to determine the type of fault. The data used in this research is local seismic data downloaded from webdc.eu. Seismic data was analyzed using waveform inversion method implemented in ISOLA program. In the ISOLA program, data processing is carried out which includes: inputting 3-component seismic data, earthquake info events, selecting stations, green functions, performing inversion, and displaying results in the form of tensor moment values, strike, dip, and rake values. From the data analysis, the moment tensor value is obtained with the range of each component of M11 is -8.348 to -3.673, M22 is 0.710 to -2.037, M33 is 7.639 to 5.710, M31 is 2.050 to 3.761, M32 is 3.484 to -5.672, M12 is -2.751 to 2.455. Then the inversion results obtained in the form of fault parameters, namely strike, dip, and rake for two nodals that will be analyzed to determine the fault plane. Based on the moment tensor value, it is found that the type of earthquake fault in 2022 in Mentawai region is dominated by reverse fault and oblique fault patterns.

Abstract

21st-century learning plays an important role in producing quality human resources. One of the skills that students must have to face this century is critical thinking skills. This research aims to determine students' critical thinking skills and find out to what extent the stages of inquiry learning have been implemented, as well as their integration with the STEM approach. The type of research used is survey research. The instruments used were interview guide sheets, tests of student critical thinking skills, observation sheets of learning implementation, and analysis sheets of the interviews conducted with 4 physics teachers in the four schools. The research results show that learning in schools is still conventional (teacher-centered). The integration of the inquiry process with the STEM approach in learning and the teaching materials used is still low. Students' critical thinking skills are also low. Therefore, the recommendation from this preliminary study is that there is a need to develop physics teaching materials that integrate inquiry learning with a STEM approach to improve students' critical thinking skills.

Abstract

Abstract:  West Java province was in a subduction zone and fault zone (slip fault), which caused earthquakes. Therefore, it was necessary to research estimates of maximum ground acceleration in West Java to mitigate earthquake disasters. This research also aimed to determine the value of ground acceleration and earthquake intensity and to determine the distribution map using the McGuire method and the Lin & Lee method. The data used were earthquake data for 1950-2023 with a magnitude > 5 SR. From processing this data, the maximum ground acceleration value in West Java ranged between 10.14722-195.3540 gal, and the maximum intensity value was IV-VI MMI using the Mc Guire method. Meanwhile, for the Lin & Lee method, it ranged between 6.6512 to 49.24599 gal. Of the two methods, the largest maximum ground acceleration value was located in Cianjur Regency, which was due to its proximity to the Cimandiri fault and the geological conditions in the area.
