Abstract

Indonesia diperkirakan memiliki potensi sumber daya panas bumi sebesar 29 GW, namun baru 2,4 GW yang teridentifikasi akibat minimnya eksplorasi mendetail. Zona hidrotermal menjadi salah satu indikator keberadaan sistem panas bumi. Penelitian ini bertujuan mengidentifikasi zona hidrotermal di Nagari Malampah, Kabupaten Pasaman, Sumatera Barat, menggunakan metode resistivitas konfigurasi Schlumberger. Data diinterpretasikan melalui inversi least-squares dengan bantuan software Res2DInv. Hasil interpretasi menunjukkan tiga zona resistivitas: zona rendah (0,10–8,46 Ωm) diduga sebagai lempung teralterasi hidrotermal/cap rock, zona menengah (4,84–429 Ωm) diduga sebagai batuan vulkanik terekahkan berpotensi reservoir, dan zona tinggi (>203 Ωm) diduga sebagai batuan dasar andesit masif. Dari lima lokasi pengukuran, Lokasi 3, 4, dan 5 diestimasi memiliki prospek hidrotermal. Lokasi 4 merupakan lokasi yang paling prospektif karena menunjukkan zona resistivitas rendah yang paling luas dan menerus pada kedalaman sekitar 5–20 m, yang mengindikasikan keberadaan zona alterasi hidrotermal. Metode ini terbukti efektif menduga zona hidrotermal dangkal dan dapat menjadi dasar eksplorasi panas bumi lanjutan di wilayah tersebut.

Abstract

Physics learning requires supporting teaching materials, especially on the subject of global warming. This subject requires students' problem-solving ability. Preliminary studies show that students' problem-solving ability are still relatively low. One possible alternative to address this issue is to develop a global warming worksheet based on a generative learning model using cognitive conflict to facilitate students' problem-solving ability. The purpose of this study is to determine the validity and practicality of the global warming worksheet using a generative learning model based on cognitive conflict. This research is a development (R&D) that uses the ADDIE development model. The ADDIE development model is one of the systematic learning design models. The object of this study is a global warming worksheet using a generative model based on cognitive conflict. The measurement data used are validity and practicality. The data obtained were analyzed using descriptive statistical techniques. The validity test indicates that the worksheets were valid for use with a score of 0.91 by experts.

Abstract

Clay in West Sumatra has been developed as an industrial material, one of which is a natural dye for batik. The use of clay as a natural dye was previously known to have magnetic minerals contained in clay so as to produce color and resistance to fabrics. Currently, no one has investigated the types of magnetic minerals found in clay and their effect on color resistance in batik cloth, so this study aims to determine the types of magnetic minerals in clay and their effect on color resistance in batik cloth. Clay samples were taken from two areas in West Sumatra, namely Pesisir Selatan and Sijunjung. Samples were characterized from the extraction of clay using X-Ray Diffraction, where measurements were taken before and after the dyeing process on the fabric. The results showed that the types of magnetic minerals found in the clay before and after dyeing the fabric were Maghemite. In addition, the non-magnetic mineral found in clay is Quartz. The color resistance test on the CL-SPPS-210314-2 fabric sample did not change color, on the contrary, the CL-PSBSJJ-210421 fabric sample experienced quite a change from the original color of the fabric or before washing.

Abstract

This study assesses seismic vulnerability in Pantai Cermin District, West Sumatra, using microtremor measurements analyzed through the Horizontal to Vertical Spectral Ratio (HVSR) method. Ambient vibration data were systematically acquired to characterize local site effects by deriving dominant frequency (f₀) and amplification factor (A₀), which reflect the dynamic behavior of near-surface soil layers. These parameters were integrated to compute the seismic vulnerability index (Kg) as an indicator of potential soil deformation under seismic loading. The results reveal pronounced spatial variability in f₀, A₀, and Kg values, strongly controlled by geological conditions. Areas dominated by young alluvial deposits and unconsolidated sediments exhibit low dominant frequencies, high amplification, and elevated Kg values, indicating high susceptibility to seismic ground motion amplification. Conversely, zones underlain by compact volcanic and intrusive rocks show more stable seismic responses. The spatial correspondence between high Kg zones and densely populated areas highlights increased seismic risk due to the interaction between site effects and exposure. The consistency between HVSR characteristics, geological framework, and vulnerability patterns demonstrates the robustness of the microtremor-based approach for seismic microzonation. This study provides a scientific basis for risk-informed land-use planning and earthquake mitigation strategies in seismically active regions.

Abstract

Bencana tanah longsor memiliki frekuensi tinggi di Indonesia, salah satunya terjadi di Jorong Siparayo, Nagari Malampah. Deformasi pasca-gempa bumi Pasaman 2022 di wilayah tersebut menyebabkan ketidakstabilan lereng yang memicu terjadinya pergerakan massa tanah melalui bidang gelincir bawah permukaan. Oleh karena itu, penelitian ini bertujuan mengidentifikasi bidang gelincir menggunakan metode geolistrik tahanan jenis konfigurasi dipole-dipole sebanyak 5 lintasan sepanjang 195 meter dengan spasi elektroda 5 meter. Pengolahan data menggunakan bantuan software res2dinv melalui proses inversi least-squares untuk menghasilkan penampang tahanan jenis dua dimensi (2D) sebenarnya. Hasil penelitian menunjukkan nilai tahanan jenis di lokasi penelitian secara keseluruhan berkisar antara 0,0069-17231 . Lapisan tanah penutup terdiri atas lempung jenuh air, aluvium, dan tanah rombakan pasiran dengan nilai tahanan jenis 0,0069-618  pada kedalaman 0 hingga >21 meter. Di bawahnya, terdapat batuan dasar berupa Andesit Masif dengan tahanan jenis tinggi mencapai >17231 . Bidang gelincir teridentifikasi pada batas kontak mekanis antara lapisan penutup gembur yang jenuh air dengan batuan dasar Andesit kompak yang kedap air. Geometri bidang gelincir bervariasi meliputi pola cekungan melandai dengan kedalaman >21 meter hingga pola bergelombang pada segmen lereng atas dengan kemiringan sudut lereng kritis lapangan 31° hingga >42°. Kebaruan penelitian ini terletak pada pemetaan variasi geometri dan batas lapisan bidang gelincir yang dipicu langsung oleh pergeseran tanah pasca-gempa 2022 di area lereng yang curam.

Abstract

Kesenian tradisional Minangkabau menghadapi ancaman penurunan eksistensi akibat modernisasi dan minimnya regenerasi pelaku seni. Tambua Tansa, sebagai warisan musik tradisional khas Nagari Manggopoh, Kecamatan Lubuk Basung, Kabupaten Agam, Sumatera Barat, memiliki nilai historis dan filosofis yang belum terdokumentasi secara sistematis. Penelitian pengabdian ini bertujuan untuk mendokumentasikan, menganalisis kondisi eksistensi, dan merumuskan strategi pelestarian Tambua Tansa melalui pendekatan Kuliah Kerja Nyata (KKN). Metode yang digunakan adalah kualitatif deskriptif dengan teknik pengumpulan data observasi partisipatif, wawancara mendalam kepada tetua adat dan seniman, serta dokumentasi audio-visual. Kegiatan dilaksanakan selama satu bulan pada tanggal 9 Januari hingga 9 Februari. Hasil penelitian menunjukkan bahwa Tambua Tansa masih bertahan dalam upacara adat dan peringatan hari besar nagari, namun menghadapi tantangan regenerasi pemain, keterbatasan instrumen, dan minimnya dukungan kelembagaan. Intervensi KKN berhasil menghasilkan dokumentasi digital, pelatihan dasar bagi generasi muda, dan inisiasi pembentukan sanggar Tambua Tansa. Simpulan penelitian menegaskan bahwa keberlanjutan Tambua Tansa memerlukan kolaborasi berkelanjutan antara masyarakat nagari, akademisi, dan pemerintah daerah melalui program revitalisasi berbasis kearifan lokal.

Abstract

Lembah Gumanti Subdistrict, Solok Regency, is one of the areas traversed by the Suliti segment of the Sumatran Fault system and is therefore at high risk of earthquakes. Previous studies have generally examined seismic vulnerability indices in coastal areas and sedimentary basins. This study analyzes the characteristics of soil dynamic response and seismic vulnerability indices influenced by the Suliti Segment of the Sumatran Fault using 20 measurement points. The objective of this study is to characterize the spatial variation of ground motion characteristics based on dominant frequency (fo), amplification factor (A0), and seismic vulnerability index (Kg) using the HVSR method, and to interpret the relationship between these characteristics and geological conditions and the Suliti Segment in order to create a seismic microzonation map for Lembah Gumanti Subdistrict. The data were processed to obtain values for the dominant frequency, amplification factor, and seismic vulnerability index. The analysis results show that the dominant frequency ranges from 1.3 to 14.8 Hz, the amplification factor ranges from 2.8 to 10.6, and the seismic vulnerability index ranges from 0.96 to 36.5. The high seismic vulnerability values in the study area are influenced by proximity to fault lines, lithological variations, and the presence of relatively thick soft alluvial deposits. The results of this study provide information on subsurface characteristics and seismic vulnerability that can be utilized in disaster mitigation efforts, land-use planning, and the design of earthquake-resistant buildings in Lembah Gumanti Subdistrict.

Abstract

This research aims to develop LKPD based on a generative learning model on light wave material for class XI SMA that is valid and practical. The generative learning model was chosen because it is able to encourage students to actively build their understanding through interaction, reflection and discussion. This model has proven effective in improving critical thinking and problem-solving skills in physics learning. The developed worksheet is designed following the syntax of the generative learning model: orientation, cognitive conflict, disclosure, construct, application, and reflection, to support in-depth learning and link theory with real application. This research uses the Research and Development (R&D) method with the 4D development model (define, design, develop, disseminate). The define stage includes needs analysis and problem identification. At the design stage, the LKPD was designed by taking into account the content, structure, and aesthetic components. The development stage involves validity testing by experts, well as practicality testing by teachers and students. The dissemination stage is planned for wider application. The results showed that this LKPD has a very high level of validity with a validation index value of 0.94 in the content aspect and 0.86 in the structure aspect, which means that this LKPD meets the eligibility standards of the Merdeka curriculum. The practicality test shows that the LKPD is very practical with a teacher assessment score of 95% and a student assessment of 87%, so it is feasible to use it in the real field because it has been declared valid and practical.

Abstract

This preliminary study aims to analyze the level of scientific literacy among students in physics learning in Grade XI at SMAN 4 Padang. Scientific literacy is one of the essential 21st-century competencies, reflecting students’ ability to explain scientific phenomena, evaluate and design scientific knowledge, and interpret data and scientific evidence. A descriptive quantitative approach was employed, using a scientific literacy test instrument developed based on indicators from the Ministry of Education, Culture, Research, and Technology (Kemendikbudristek). The research subjects consisted of 31 Grade XI students. The analysis results show that the average achievement in students’ scientific literacy was only 38.96%, with the following breakdown: explaining scientific phenomena (36.88%), evaluating and designing scientific knowledge (38.75%), and interpreting data and scientific evidence (41.25%). These findings indicate that students' scientific literacy skills remain low and do not meet the expected standards. Therefore, the study highlights the urgent need for the development of innovative physics learning models that enhance active engagement, conceptual understanding, and scientific thinking skills.
