Abstract

Conceptual skills in physics are an essential foundation for students to understand natural phenomena deeply and analytically, yet conventional teaching often fails to connect abstract theory with real-life contexts. This study aims to develop a physics learning module integrated with the local wisdom of the Toba Batak Taganing on mechanical wave material to enhance students' conceptual skills. The developed module links concepts of waves, resonance, and interference with the acoustic principles of the Taganing musical instrument through a Problem-Based Learning approach. Expert validation results demonstrated a high level of feasibility, with details of 78% (Feasible category) by subject matter experts, 85% (Highly Feasible) by cultural experts, and 97% (Highly Feasible) by language experts. A limited trial with grade XI students showed an improvement in conceptual skills, specifically an abstraction ability of 71% (Good) and systematic thinking of 72% (Good). Teacher and student responses to the module were very positive, with a practicality level of 81%, indicating that the module is not only easy to use but also contextual and engaging. These findings confirm that integrating local wisdom into ethnoscience-based physics learning design is not only effective in strengthening students' conceptual understanding but also plays a strategic role in preserving cultural heritage and fostering learning engagement.

Abstract

Increasing energy demand and high world oil prices are making countries turn to geothermal energy use. Indonesia is a country that has geothermal energy due to Indonesia's geographical location and geological conditions, which is located between three active earth plates so that Indonesia has 240 volcanoes and often experiences earthquakes. The 2003-2013 earthquake data obtained are coordinates, magnitude, depth, focal mechanism and all these data are analyzed in the coulomb stress method. Rianiate geothermal measurement data in March 2013 included geothermal location, hotspring and air temperature, pH, and geochemical measurements. The analysis results showed that the highest coulomb stress value was at a depth of 90 km of 0.56 bar while the shear and normal values were 0.452 bar and 0.251 bar. The result of the spread of coulomb stress is to the northeast, east and southeast. Then the results of the analysis of the direction of distribution of coulomb stress are compared to the location of the hotspring based on a decrease in temperature, the change in the potential of hotspring 1 leads to hotspring 2, 3, and 4 in the opposite direction, namely northwest or leads to the largest source of colulomb stress, so that Coulomb Stress Changes affect indirectly changes in the geothermal potential of Rianiate

Abstract

The great Aceh earthquake on December 26, 2004, had a magnitude of 9.2 Mw for 10 minutes with coordinates 3,316°N 95,854°E. had a tremendous impact on changes in geological conditions and disasters in Aceh and Asia, especially Southeast Asia and South Asia. Changes in geological conditions have resulted in Aceh and its surroundings becoming more prone to earthquakes, including volcanoes in North Sumatra. This research aims to determine the value of changes in coulomb stress that occur on Mount Sibualbuali and Lubukraya. This research uses the coulomb stress method presented in Coulomb 3.4 software. This research produces positive coulomb stress changes in 2021 which are marked by the red lobe, namely 0.197 bar on Mount Sibualbuali and 0.187 bar on Lubukraya. The highest increase in chwerees in coulomb stress was in 2015, namely 0.319 bar in Sibualbuali and 0.262 bar in Lubukraya. This research also resulted in the highest coulomb stress changes at a depth of 90-100 km so that it does not affect the volcanic activity of the two mountains.

Abstract

Ketatnya persaingan dalam era globalisasi mendorong pemerintah Indonesia untuk segera melakukan perbaikan terutama di bidang pendidikan. Alasan utama perbaikan di bidang pendidikan karena kualitas sumber daya manusia ditentukan oleh model pendidikan.. Salah satu bidang pendidikan yang perlu ditingkatkan adalah kemampuan dalam hal penguasaan bahasa asing, khususnya bahasa inggris. Kegiatan PKM dilakukan di SMA Advent Simbolon Kabupaten Samosir selama kurang lebih 4 minggu Kegiatan PKM yang dilakukan adalah English Club dan Mading Kreatif. Metode pengabdian yang dilakukan adalah metode diskusi. Kegiatan Minggu pertama berupa English Club. Kegiatan Minggu kedua berupa English Club dan Les Bahasa Inggris. Kegiatan minggu ketiga berupa English Club, Les Bahasa Inggris, dan Mading Kreatif. Kegiatan minggu Keempat berupa English Club, Les Bahasa Inggris, Mading Kreatif dan Seminar Singkat “Digital Youth : Pendidikan di Era Digital Untuk Generasi Z”. Kegiatan ini memberikan hasil berupa peningkatan keterampilan berbicara Bahasa Inggris berdasarkan meningkatnya antusias, pemahaman materi, dan peningkatan kepercayaan diri siswa/i SMA Advent Simbolon.
