Abstract

The distribution of non-volcanic geothermal energy is widely found on the island of Sulawesi, one of which is in Lompio Village, Sirenja District, Donggala Regency, Central Sulawesi Province. It is important to study the geothermal potential in the village in order to learn how the geothermal system works. This study aims to identify the distribution pattern of temperature distribution in shallow soil depths as a manifestation of the geothermal system below the surface and its relation to geothermal manifestations that appear on the surface. This research was carried out through a series of field observations and direct soil temperature measurements in the study area using a thermometer. The results show that the distribution pattern of land temperature distribution in the high-temperature zone is associated with the presence of geothermal manifestation points on the surface (hot springs). The association of temperature and manifestation is possible because the presence of hot springs is an indication of a weak zone for the release of hydrothermal fluid from the geothermal system, which is correlated with the geological structure in the research area.

Abstract

The Kawatuna area has a complex geological structure and lithological condition of metamorphic rock, which is estimated to be a weak zone for hydrothermal solutions to rise and then accumulate as mineralization of veins in the metamorphic rock. Based on this, it makes this area interesting to research. This research aims to identify metal ore minerals and the mineralization characteristics of ores in the research area. The method used is a geological survey of the surface and laboratory analysis through ore microscopic as well as mineral chemistry tests. Based on the results of the research study, it was found that in metamorphic rocks in the Kawatuna area, sulfide metal ore minerals were found including argentite (Ag2S), pyrite (FeS2), chalcopyrite (CuFeS2), sphalerite (ZnS), galena (PbS), and covelite minerals (CuS), Native elements ore minerals include gold (Au), silver (Ag), electrum (Au, Ag), and Oxide ore minerals in the form of hematite (Fe2O3). The mineralization formed is controlled by structures that produce fractures in the rock, which then produces mineralization as the veins of metamorphic rocks. The ore mineralization in the research area occurs through a hypogene process (the formation of a formation zone from primary ore minerals) and a supergene process stage (the formation of a formation or enrichment zone from secondary ore minerals).

Abstract

The development of digital technology has brought significant changes in the field of education, particularly in the use of software such as Microsoft Word as a learning tool. This study aims to analyze students' understanding of basic and advanced features of Microsoft Word, identify obstacles faced in its academic use, and provide recommendations for effective mentoring strategies. A descriptive quantitative method was employed, using a Likert-scale questionnaire and semi-structured interviews involving 20 students from grades VII–IX and 2 teachers at MTS Muhammadiyah, Bima Regency. The results indicate a notable improvement in learning outcomes among students who actively used Microsoft Word compared to the control group, with the majority (70%) giving highly positive responses to its implementation. In addition to enhancing material comprehension and text processing skills, Microsoft Word has also proven effective in creating a more engaging and interactive learning environment. However, limitations in the use of advanced features were still observed due to insufficient guidance. Therefore, structured training for both teachers and students is essential to optimize the use of Microsoft Word in 21st-century digital learning

Abstract

Introduction: The Patukuki area in the Central Peling sub-district falls administratively within the geographical coordinates of 123°01'00" – 123°01'3" longitude and 01°24'00" – 01°27'00" latitude. Method: Channel Sinuosity (S) measures river influence on landscapes by comparing actual river length to valley length. Mountain-front sinuosity (Smf) evaluates mountain-front curvature using base and straight-line lengths. The Valley Floor Width to Width-to-height ratio (Vf) identifies regions of rapid uplift, with lower values indicating higher activity. The Asymmetric Factor (AF) detects tectonic tilting in drainage basins by comparing the area of the right-hand side sub-basin to the total area. Results and Discussion: Based on the analysis conducted, the findings are as follows: Channel Sinuosity analysis shows that sub-bases 1, 2, and 3 have high tectonic activity, while sub-base 5 has moderate activity, and sub-base 3 is low. Stream Morphology Frequency (Smf) analysis shows moderate tectonic activity in sub-bases 1, 3, 4, and 5, and sub-base 2 with an average Smf value of more than 1.5. Valley floor width to height ratio (Vf) shows low tectonic activity in all sub-bases. Anisotropy of Magnetic Susceptibility (AF) shows that sub-bases 1 and 5 have high tectonic activity, sub-bases 3 and 4 are moderate, and sub-base 3 is low. The IATR values of sub-bases 1, 4, and 5 are between 1.5 and less than 2, while sub-bases 2 and 3 show moderate tectonic activity with IATR values between 2 and less than 2.5.Conclusion: In summary, tectonic activity in the Patukuki watershed ranges from moderate to high based on the various analyzed indices.

Abstract

Ruas jalan Desa Salua di Kabupaten Sigi, Sulawesi Tengah, dinilai rawan longsor akibat kondisi geologi, geometri lereng, dan guncangan gempa seperti pada tahun 2018. Penelitian ini bertujuan menilai kestabilan lereng sebagai acuan perencanaan struktural guna meminimalkan risiko longsor. Interpretasi tingkat kestabilan lereng merujuk dari nilai faktor keamanan (FS) yang diperoleh dari penerapan limit equilibrium method (LEM) menggunakan kaidah Bishop. Penelitian diawali dengan identifikasi litologi lereng berupa diorit dari Formasi Batuan Terobosan. Estimasi sifat mekanika batuan dilakukan melalui kriteria Hoek-Brown, Geological Strength Index (GSI), dan uji berat isi di laboratorium untuk memperoleh parameter Mohr-Coulomb. Model lereng kemudian dianalisis dalam kondisi dinamis dengan asumsi adanya guncangan. Hasil menunjukkan nilai faktor keamanan (FS) secara deterministik sebesar 6,191 dan probabilitas kelongsoran (PF) sebesar 2,493%. Meski nilai FS menunjukkan lereng stabil (FS > 1), potensi longsor parsial tetap ada akibat pelapukan tidak merata. Riwayat longsor di lokasi membuktikan bahwa guncangan berperan signifikan, sehingga diperlukan penanganan seperti tanggul penahan, paku bumi, geotekstil, serta rekayasa geometri lereng guna meningkatkan kestabilan terhadap guncangan.
