Abstract

The aim of this research is to develop augmented reality learning media with a problem-based learning model and analyze the feasibility, practicality, and effectiveness of augmented reality learning media with a problem-based learning model in improving students' understanding of mathematical concepts. This research uses the research and development method with the ADDIE model (Analysis, Design, Development, Implementation, Evaluation). The sampling technique used is a random assignment, namely random sampling, where the experimental and control groups are chosen randomly from a lottery. The first lottery that came out was used as the experimental class, and the second lottery was used as the control class. Data collection techniques in this research used interview techniques, questionnaires, and tests. The results show (1) augmented reality learning media with a problem-based learning model is suitable for use, (2) augmented reality learning media is very practical to use, (3) understanding of mathematical concepts of students who receive learning with augmented reality media is better than students with conventional learning, and there are significant differences. (4) The augmented reality-based learning media developed is effective in use. The findings imply that the augmented reality learning media with a problem-based learning model can be an alternative and innovative media in assisting the student’s comprehension on mathematical concepts

Abstract

This study aims to explore ethnophysical concepts embedded in Borobudur Temple and to develop a contextual physics enrichment book for senior high school students. Indonesia possesses a rich cultural heritage with strong potential for contextualized science education, and Borobudur Temple—an architectural masterpiece that embodies various physics principles—offers a unique opportunity to design culturally relevant learning resources. The research employed a Research and Development (R&D) approach using the AM3PU3 model and a one-group pretest–posttest design involving 74 students from SMA Negeri 1 Tengaran. Data were collected through expert validation, student questionnaires, and pretest–posttest scores, and analyzed using the N-Gain test. The findings indicate that mechanical concepts grounded in ethnophysics are present in the temple’s structure and can support culturally based physics instruction. The developed book received expert validation scores of 3.40 for content, 3.83 for language, and 3.63 for presentation (on a 1–4 scale). Student responses were also high, with scores of 4.00 for readability, 3.98 for effectiveness, and 3.90 for design (on a 1–5 Likert scale). The N-Gain result of 0.30 indicated a moderate improvement. These findings suggest that integrating ethnophysics may serve as a culturally responsive strategy to enhance students’ conceptual understanding and engagement in science education.

Abstract

Indonesia is a country that has volcanoes stretching from west to east from Sumatra, Java to Sulawesi. Mount Arjuno-Welirang is a stratovolcano type volcano with an altitude of about 3,339 m (10,955) for Mount Arjuno while for Welirang it is about 3,156. Mount Arjuno-Welirang and its surroundings are composed by rocks sourced from Anjasmoro Volcano (Early Plistocene), Ringgit-Pundak-Butak Volcano (Middle Plistocene), Arjuno-Welirang Twin Volcanoes I and II (Late Plistocene), and Penanggungan Volcano. This research includes data processing and interpretation of the results of data processing.  This research was conducted using geophysical methods, namely the gravity method. The theoretical basis used is Newton's Law. Data in the form of gravity data that has been downloaded on the Land Gravity Data Website which is then processed using Surfer software, then the Magpick Software Upward Continuation process is carried out. After that, the slicing process is carried out on the residual anomaly, then the slicing results will be used to interpret using Grav2DC Software qualitatively based on the geological map as a reference. The interpretation results on the A-B and C-D tracks obtained 4 rock layers, namely volcanic breccia, lava, tuff breccia, and tuff rock. With an error value of 8.25% for incision A-B, and 3.63% for incision C-D.
