Abstract

The rapid development of technology has brought significant changes in the world of education. Students are expected to be able to understand technology in learning. Based on observations conducted at SMAN 3 Solok, several problems were found in physics learning, including the limited availability of interactive digital teaching materials and low technological literacy and conceptual understanding of students. To address this, a needs analysis stage was conducted with a Research and Development (R&D) approach using the Hannafin and Peck model. Data were obtained from teacher questionnaires in the form of teaching material use, student questionnaires to determine student characteristics, technological literacy performance assessment sheets in the form of questions according to technological literacy indicators, and learning outcome documents to see student conceptual understanding. The results of the analysis showed that the teaching materials used were not yet technology-based, students' technological literacy skills were low, and student scores were still below the minimum completeness criteria. Based on these data, it is necessary to develop interactive multimedia teaching materials that integrate conceptual understanding and technological literacy.

Abstract

The development of education in the 21st century demands teachers to innovate by integrating technology into the learning process and fostering students’ creative thinking skills. However, preliminary studies revealed that students’ creative thinking abilities remain low, and the existing teaching materials have not fully supported joyful and engaging learning. This study aims to determine the validity level of a digital learning material on the topic of heat, integrated with the Joyful Learning approach to enhance students’ creative thinking skills in senior high school. The research employed a Research and Development (R&D) method using the Hannafin and Peck model, which consists of three stages: need assess, design, and develop/implement. The research instrument used was a validity questionnaire to assess the feasibility of the developed digital material. The results showed that the digital learning material achieved a validity score of 0.95, categorized as highly valid. Therefore, the developed digital material on heat integrated with Joyful Learning is considered valid and feasible for physics learning to foster students’ creative thinking skills.

Abstract

Critical thinking is a key competency required in 21st-century learning; however, field observations indicate that students’ critical thinking skills remain relatively low. This condition is closely related to the use of teaching materials that have not optimally implemented the Problem Based Learning (PBL) model and have not integrated local cultural contexts. To address this gap, this study developed digital teaching materials on global warming integrated with Ethno-Problem Based Learning (Ethno-PBL). The purpose of this study was to determine the validity of the developed Ethno-PBL-based digital teaching materials as a foundation for supporting the development of students’ critical thinking skills. This research employed a research and development approach, limited to the product validation stage conducted by expert validators. The validation process evaluated five aspects: material substance, learning design, visual communication, software utilization, and Ethno-PBL integration. The results showed that the developed digital teaching materials achieved a high level of validity, with an average validity score of 0.94. Specifically, the validity scores for material substance, learning design, visual communication, software utilization, and Ethno-PBL integration were 0.90, 0.95, 0.96, 0.97, and 0.94, respectively. These findings indicate that the Ethno-PBL-based digital teaching materials are valid, feasible, and beneficial for use in physics learning on global warming topics, and have the potential to facilitate more contextual, meaningful, and critical learning experiences for students.

Abstract

This study investigates the influence of solar declination and right ascension on extreme temperature variability in West Sumatra during the 2020–2024 period using a quantitative empirical framework. Monthly climatological observations were integrated with astronomical parameters calculated through high-precision algorithms to construct a harmonically structured time series dataset. The results reveal that solar declination primarily governs the amplitude of seasonal temperature variation, while right ascension regulates temporal synchronization, producing observable phase shifts between astronomical forcing and atmospheric response. Harmonic analysis demonstrates that these relationships extend beyond linear correlations by capturing periodic patterns characterized by amplitude and phase metrics. Furthermore, residual components indicate the presence of external modulators, particularly sea surface temperature anomalies and large-scale climate variability, which alter the magnitude and timing of extreme temperature events. The combined analytical approach confirms that tropical atmospheric dynamics are shaped by interactions between deterministic astronomical cycles and stochastic environmental influences, offering a more robust basis for predictive climatological modeling and advancing the understanding of solar–atmosphere coupling in equatorial regions.

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.
