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.

Abstract

Improving digital literacy has become an essential need in today’s technological era, including within church communities, so that congregants can utilize technology wisely and productively. This study aims to analyze the impact of the AI Application Education as a Means to Strengthen Digital Literacy workshop on the knowledge, skills, and attitudes of congregants at GPI Paya Kapar. The method employed is descriptive-participatory within a community service framework, using data collection techniques such as observation, pre-test and post-test questionnaires, brief interviews, and activity documentation. The workshop was structured into three main sessions: theoretical presentation, hands-on practice using AI applications, and reflective discussion. The results indicate a significant improvement in participants’ knowledge of digital literacy and AI application, practical skills in using digital tools for learning and church activities, as well as more responsible attitudes and motivation in utilizing technology. These findings confirm the effectiveness of a participatory-educative, community-based approach in enhancing digital literacy and practical AI skills.
