This study uses a qualitative descriptive approach with a literature study methodology. The results of this study indicate that the theory of relativity in Science describes the special theory of relativity : This theory demonstrates the concept of the speed of time, making time relative. Time as a physical variable is also affected by the lack of a universal frame of reference. When a frame moves relative to a frame of reference, a still reference, the time experienced by a person in a moving frame will be different from the time experienced by a person in a stationary frame. This time difference is called time dilation (relativity temporal) And only applies if moving at the same speed. At the same time, Science in the theory of relativity is used in various fields, including cosmology, satellite technology, and astrophysics. So, the theory of relativity in understanding Science Science has a relevant relationship. Applying the theory of relativity in Science can help overcome the difficulty of understanding students and the general public towards abstract physics concepts and facilitate the development of technology.

This study aims to assess the extent to which social factors influence students' understanding of physics concepts. The factors examined include social relationships within the family, peer influence, and the students' environment. The research employs a quantitative approach using simple linear regression and descriptive correlation methods. Data were collected through questionnaires involving 34 female students in a physics class. The analysis results indicate that in the F test, the obtained value was 0.126 with a significance of 0.00, while in the regression test, the regression value was 0.063. The correlation test for students’ conceptual understanding of physics resulted in a significance value of 0.725. Based on these findings, it can be concluded that social factors do not have a significant influence on learning outcomes and students’ understanding of physics concepts. This suggests that other factors beyond social aspects play a more significant role in supporting students' comprehension of physics material.

Drum dryers are an important component in the agro-industry, particularly in corn processing. These dryers are designed to dry materials at high temperatures, utilizing a mechanical motor system that opens and closes the exhaust valve to control and stabilize the heat inside the rotisserie. This research employed a mixed-method approach, as well as direct observation. The results of this corn drying machine study revealed a deviceequipped with an inlet and outlet. The inlet is a funnel, and the outlet is a hole under the drum. This device is very economical for drying corn

Advances in science and innovation affect the progress of education in Indonesia. The current situation in Indonesia is characterized by a lack of competent human resources (HR). A quality education helps students develop the values they need to live. The purpose of this study is to describe students' critical thinking skills so that efforts to apply the STEM-based PBL approach can provide maximum results of research that will be carried out in grade VII of SMP IT Ibnu Sina. A quantitative descriptive approach is used in this study. Description of 10 questions based on critical thinking is the instrument used in this study. The instrument to be used has been validated. The results of expert validation of the questions received an average score of 91.55%. The results of the data analysis showed that the students' critical thinking skills in the interpretation indicator obtained an average score of 64% so that it could be interpreted in the good category. In the analysis indicator, an average score of 64% was obtained, which can be interpreted in the good category. In the conclusion indicator, an average score of 64% was obtained, which was included in the good category. Similarly, in the evaluation indicator, the average score obtained by students is 60% which is included in the sufficient category. As well as in the elaboration indicator, the average score obtained by students is 60%, which can be interpreted in the sufficient category

Analysis of Absorption Values and Absorption Coefficients of Materials: Particle Board, Plywood, and Dutch Teak Wood

Wed, 10 Sep 2025 00:00:00 +0700

Acoustic performance is strongly influenced by the ability of materials to absorb sound across different frequency ranges. This study investigates the absorption values and absorption coefficients of three wood-based materials particle board, plywood, and Dutch teak wood at audio (1.2–3 kHz) and ultrasonic (35–45 kHz) frequencies. Experimental results show that particle board exhibits the highest absorption in the audio range, attributed to its porous structure that effectively attenuates sound waves. Plywood demonstrates variable absorption behavior, with superior performance at higher ultrasonic frequencies. Dutch teak wood displays the most stable acoustic response across both ranges, achieving the highest absorption coefficient of 1.51 at 35 kHz. Additional analysis of density and moisture content indicates that porosity and humidity significantly affect sound absorption characteristics. Overall, the findings provide a comparative basis for selecting wood-based materials in acoustic applications, including architectural design and soundproofing products, and suggest further research on the influence of environmental factors on absorption capacity.

The Effect of Using Phet Simulation Media on Physics Learning Achievement: A Literature Review

Wed, 10 Sep 2025 00:00:00 +0700

This study aims to examine the effect of using PhET (Physics Education Technology) simulation media on students' physics learning achievement through a literature review approach. Eight relevant scientific articles were selected based on specific inclusion criteria, such as the use of PhET in physics learning and the presentation of quantitative data on student learning outcomes. The review results indicate that all the articles concluded that there was a significant improvement in student learning outcomes after using PhET media. This simulation has proven effective in helping students understand abstract physics concepts, increasing participation and motivation to learn, and supporting critical thinking skills. Additionally, PhET is flexible and can be applied in various learning models, such as problem-based learning and scientific inquiry. Despite its numerous advantages, the success of PhET implementation heavily depends on teachers' readiness and the availability of technological infrastructure. Thus, PhET simulations have the potential to become an innovative and efficient learning tool in enhancing the quality of physics education.
