Abstract

Research has been carried out on the design of a mini power bank using dragon paste as a source of electrical energy. The voltage and current produced by this dragon paste and power bank are measured using a digital multimeter. Dragon paste used in series and parallel. The voltage generated by the dragon paste is connected to a DC step up. The use of step up dc aims to increase the dragon paste voltage, so that the resulting voltage can reach a maximum of 5.16 V and can charge lithium-ion batteries that have been arranged in parallel using the power bank kit module.

Abstract

Based on the results of observations and interviews at SMAN 5 Palangka Raya, physics learning is still not structured optimally to achieve students' critical thinking skills. As a result, research was undertaken employing POE-based e-modules to aid students in achieving learning competencies by utilizing their critical thinking skills. The goal of this study is to see how successful POE-based e-modules are at improving critical thinking skills. A quantitative approach using a One Group Pretest-Posttest Design was applied. A test in the form of a description question served as the data gathering strategy. The findings revealed that this POE-based e-module was beneficial to students' critical thinking abilities. The e-effectiveness module's was determined using an effect size of 3.24, which falls into the very high category. This study's conclusion is this POE-based e-module improves students' critical thinking skills.

Abstract

This research is motivated by the lack of interest in learning physics and the unavailability of interesting learning materials that are suitable for student characteristics and can support the creation of innovative learning. This study aims to produce a new product in the form of a valid PBI-oriented physics learning module. This type of research is development research using a 4D mosel (four-D Model),the research procedure used is 4-D, namely definition, design, development, dissemination due to time and cost limitations. then this step is not implemented. The research instrument used was the initial analysis sheet, the validity sheet. From the results of the research conducted,it was found that the problem based instruction-oriented learning module was categorized as very valid with an average overall score of 82.24%. This research resulted in a problem based instruction (PBI) oriented physics learning module on light materials and optical instruments for class VIII which was very valid.

Abstract

This research aims to develop LKPD using liveworksheets based on problem based learning on light matter. The research method used is development (research and development) with the Sugiyono development model. The results of LKPD validity have been declared very valid based on the results of validation of learning material experts obtained a value of 88% with a very valid category, and the teaching material expert obtained a value of 88% with a very valid category, and the category of all validators is very valid with a value of 83%. In addition, LKPD is stated to be very practical with a value of 88.89% without revision. Based on the response of students obtained a score of 95.25% with an excellent category. Based on the acquisition of these data, it can be concluded that LKPD using a problem-based learning liveworksheet in light matter is declared very valid and very practical to be used as an IPA teaching material in school.

Abstract

Physics is a branch of scientific knowledge that requires understanding other disciplines, such as mathematical concepts. As for the development of increasingly advanced technology, it affects the world of education such as the implementation of CBT (Computer Based Test). Based on this, of course, innovation is needed to solve physics problems in a short and easy time. One example of material taught in physics that can be done in an easier way is material on special relativity. The solution to the problem of Einstein's special relativity, especially the comparison of relativistic energy, can use a right triangle by fulfilling the Pythagorean equation. This study describes the analysis of the right triangle theorem with the relativistic energy comparison equation.

Abstract

Students' confidence in their ability to study material and work on physics questions needs to be a concern during the covid-19 pandemic. This belief is called self-efficacy. This self-efficacy can be increased by using teaching materials that are designed by educators according to the characteristics of the students they teach. Concept-based modules are used in basic physics lectures on Particle Dynamics. This study aims to describe the increase in student self-efficacy before and after using the module. In addition, this study also wanted to see whether there was a significant difference in student self-efficacy between before and after using the module. This research method uses a pre-experimental method with one group pretest posttest design. The sample used in the research is odd semester students for the 2021/2022 academic year. The results showed the <N-Gain> value of 0.45 which indicated that there was an increase in student self-efficacy after using the concept-based module in the moderate category. The difference in student self-efficacy between before and after using the concept-based module was also significant by referring to the sig value. (2-tailed) 0.000 < 0.05.
