Abstract

This study purposed to develop an E-student worksheet on environmental pollution material to improve the critical thinking skills of junior high school students. E-student worksheet is an electronic-based student worksheet that utilizes the internet in its application. E-student worksheets can create various kinds of content, both visual and audiovisual, to train and assist students in finding concepts through the learning process. The development research method used a 4-D model, but only three stages were carried out: defining, designing, and developing. This research was conducted on seventh-grade students at SMPIT Al Ghozali Jember. The instruments used in this study were validation sheets, learning implementation sheets, critical thinking skills tests, and student response questionnaires. The results of this study indicated that the E-student worksheet had very valid criteria with a value of 94%. The implementation of learning showed very high criteria with a value of 92%. The effectiveness of learning had effective criteria with an average N-gain value of 0.70, and student responses had a good criterion, with a value of 77.3%. It can be concluded that the E-student worksheet on environmental pollution material could improve students' critical thinking skills in science learning in junior high school

Abstract

The vulnerability of landslides in Lantan Village, North Batukliang District, Central Lombok Regency has been analyzed using geoelectric data, rainfall, soil movement, and topographic slope. Resistivity data was acquired by the G-Sound resistivity meter using the dipole dipole configuration method and visualized using the RockWorks15 software. We also used rainfall data and ground movement data.  The ground movement was estimated from Sentinel-1A satellite data, processed using the DInSAR (Differential Interferometry Synthetic Aperture Radar) method. The slope data was obtained based on the topographic slope map of the Central Lombok Regency. The results showed that the slip surface was indicated to be located in silt clay with sand and the direction of the landslide in the study area was to the northwest with the type of landslide that might occur was a type A translational landslide. The depth of the slip surface varies from 1.5 m to 21.5 m.  The average monthly rainfall varies from low to high (<100 – 300 mm) with a monsoon rain pattern. Land movement in the form of land subsidence was observed at a rate of -0.27 to -0.30 cm/year during 2018 - 2020, with average land subsidence of -0.285 cm/year. The potential for landslides is also seen from the slope value of 40°, which is categorized as very steep. With all these conditions, the level of vulnerability to landslides in Lantan Village is high, and hopefully, the results of this study can be a reference for related parties in making efforts to minimize the impact of this disaster.

Abstract

The education process for science student teachers in Indonesia must continue, even in a pandemic situation with an unclear end. The research aims to find the most appropriate science practicum method during the Covid-19 pandemic for science student teachers. The method used in this research is mix-methods. The research design chosen by the researcher is the Pre-Experimental One-Group Pretest-Posttest Design. Participants in this study were 140 science student teachers who did distance practicum on basic biology practicum courses. Basic biology practicum is a practicum course that practices biological science, including respiration, photosynthesis, nutrient content of food, and pollutant testing. Based on gender, the participants were 62 male students and 78 female students. The value of N-Gain d > 0.58 (moderate effect) means that practicum activities can be continued as a practicum solution during the pandemic. Student activities during a practicum at home apply new adaptations different from a practicum in the laboratory. Independence in preparing materials and tools, preparing worksheets, simplifying materials, and modifying tools is a new way for students. The study concludes that a new practicum method that utilizes the environment potential is a solution in the implementation of science practicums as a result of the Covid-19 pandemic in Indonesia. The environment can be explored to find resources that can be used as practicum materials and the manufacture of basic biology practicum tools.

Abstract

This study aims to test the effectiveness of developing core physics learning tools using an inquiry model with the help of PhET media in increasing student creativity. The development of the learning device uses a 4D model consisting of define, design, develop and disseminate. The sample of this research is all undergraduate students who take nuclear physics courses, totaling 50 people. The sample consisted of two classes, namely class A as the experimental class and class B as the control class. The pre-test and post-test data were analyzed using the t-test at a significant level of 5%, while the increase in student creativity was analyzed using the N-gain test. The results of the t-test show that the t-count value is greater than the t-table, which means that the nuclear physics learning device using an inquiry model with the help of PhET media affects student creativity. The results of the N-gain analysis show that the experimental class is in the high category, while the control class is in the medium and low category. These results indicate that the use of nuclear physics learning tools using an inquiry model with the help of PhET media is effective in increasing student creativity

Abstract

The background of this research is the lack of competence of physics teachers in using physics KIT. This research was conducted with the hope that there will be an increase in the competence of senior high school physics teachers in West Pasaman in using the physics KIT. This research was conducted with a quasi-experimental design and one group pretest-posttest. This study has a population of all physics teachers who join physics teachers group in West Pasaman Regency. The sample was taken by using simple random sampling technique, selecting 22 teachers as representatives of the physics teachers group in West Pasaman Regency. The results showed an increase in teachers' competence in using the physics KIT after mentoring the use of the physics KIT. The increase in teacher competence can be described through the value of again, the N-gain value obtained is 0.33 (moderate). This means that the teacher's competence in using the physics KIT can increase after mentoring the use of the physics KIT.
