Abstract

This study investigates the relationship between SiO₂ composition and magnetic properties of Lampung Tuff from Hatta Bekauheni using an integrated approach combining rock magnetism and portable geochemical analysis. Magnetic susceptibility measurements were conducted using a Bartington MS2B sensor at low and high frequencies to determine χlf and χfd (%), while elemental composition was analyzed using Portable X-Ray Fluorescence (Portable XRF). The results indicate that all samples exhibit ferrimagnetic behavior, reflecting the presence of magnetic minerals such as magnetite or titanomagnetite with varying concentrations and grain sizes. The χfd (%) values suggest a mixture of superparamagnetic and coarser grains, indicating heterogeneous depositional and post-depositional processes. SiO₂ content varies among samples, representing local geochemical differentiation of volcanic material. However, regression analysis shows a very weak correlation between SiO₂ and magnetic parameters, as indicated by low coefficients of determination. These findings demonstrate that magnetic properties are primarily controlled by mineralogical factors rather than silica composition. The integration of magnetic susceptibility and Portable XRF provides an efficient, non-destructive framework for comprehensive volcanic material characterization.

Abstract

The high water absorption of concrete causes the concrete to easily experience cracking and damage. One way to increase the durability of concrete is by adding microbes which can fill the micro cavities in the concrete with the resulting Calcium Carbonate (CaCO3) deposits. However, the weakness of using microorganisms is that they are unable to withstand high hydration heat. Therefore, by varying the temperature in this research, it is possible to determine the effect of the metabolism of the bacteria produced. This research was carried out to avoid damage by creating a hydrophobic and self-healing layer which helps increase the durability and strength of the concrete. The concrete sample made resembles a cube measuring 5 cm x 5 cm x 5 cm. The manufacturing materials are Portland cement, Otawa sand, distilled water and a mixture of E. coli bacteria. Heating was carried out using an oven at temperatures of 30, 60, 90, and 120 oC. Characterization testing was carried out using a Cpmreson machine, XRD and contact angle testing.

Abstract

Padang City, as the capital of West Sumatra Province, often experiences heavy rains that can cause flooding and landslides. This phenomenon of heavy rainfall is a matter of serious concern due to its impact on the lives of the community, infrastructure, and the regional economy. On March 7, 2024, heavy rainfall occurred in Padang City, triggering flooding and causing loss of life and property. The analysis was conducted using weather radar imagery, satellite imagery, and rainfall observation data from several rain gauges in Padang City. To obtain representative rainfall data with broad spatial coverage, the use of remote sensing data such as weather radar images and satellite images is vital, especially for areas with a limited number of rain stations or difficult-to-reach topography. Therefore, this study aims to analyze the comparison of rainfall data based on radar imagery, satellite imagery, and rain gauge data to understand the advantages and limitations of each instrument. The combination of these three data sources is very important to improve the accuracy of rainfall monitoring. The research method used in this study is quantitative research using data from the BMKG. The results of the analysis obtained from the error and correlation, both from radar data and satellite imagery, generally show a tendency to underestimate the rainfall observed at rain gauges in Padang City, as indicated by the Mean Error (ME) value, which is predominantly negative at almost all rain gauges.

Abstract

Indonesia located along the equator and dominated by oceanic areas, is highly vulnerable to atmospheric dynamics and extreme convective weather. Minangkabau International Airport (BIM), situated in a coastal region of West Sumatra, is frequently affected by cumulonimbus (Cb) clouds and thunderstorms (TS), which pose risks to aviation safety. This study aims to determine the threshold values of the Convective Available Potential Energy (CAPE) index and the Total Totals Index (TT) that are appropriate for local conditions, based on radiosonde and synoptic observation data from 2019–2023, and verified using 2024 data. The CAPE and TT values were analyzed using Sturges’ method to determine frequency intervals and dichotomous analysis to establish threshold effectiveness. Results indicate that CAPE thresholds for Cb clouds range from 495 to 2679 J/kg, while TT thresholds for thunderstorms range from 43.5 to 47.4, depending on the seasonal variation (DJF, MAM, JJA, SON). These thresholds demonstrated strong performance in identifying convective weather events, thus serving as a useful reference for forecasting and enhancing flight safety at BIM.

Abstract

Rapid changes of the 21st century require education to develop essential skills, sustainability literacy, and complex problem-solving abilities. However, many studies indicate that students’ competencies remain low, particularly in environmental awareness, critical thinking, and problem-solving. This condition highlights the need for innovation in science learning that is more relevant to global challenges. Therefore, integrating STEM (Science, Technology, Engineering, and Mathematics) with Education for Sustainable Development (ESD) has become an important approach to improving the quality of learning. This study aims to map research trends and opportunities related to ESD-STEM integration through bibliometric analysis. Data were collected from Scopus-indexed articles published between 2015 and 2025 and analyzed using VOSviewer, including publication performance, co-authorship, keyword occurrence, and thematic mapping analyses. The results show a significant increase in publications, particularly since 2020, focusing on STEM, sustainability, and pedagogical innovation. The dominant subject areas include social sciences, computer science, and engineering, with major contributions from the United States, Indonesia, and Malaysia. These findings confirm that ESD-STEM integration promotes interdisciplinary, contextual, and sustainability-oriented learning, while opening opportunities for future research.
