Abstract

Technological and scientific progress is a characteristic of the 21st century that requires students to think creatively, communicate, critically and also collaborate. This study aims to perform a requirements analysis in developing E-Modules based on Problem Based Learning on alternative energy material and its use to Enhancing students' critical thinking abilities in high school. The conclusion of this research show five result from the needs analysis, namely: (1) The utilization of ICT in education with a score of 94 in the very good category. (2) student characteristics are good with a value of 71.80. (3) Implementation of learning objectives by teachers as observed from learning outcomes. objective flow of one physics teacher are in the sufficient category. (4) Learning arrangements implemented by teachers seen from the teaching module of one teacher are in the sufficient category. (5) analysis of students' critical thinking skills. Data were obtained from 21 grade XI students with an average of 22.77 in the less category.

Abstract

Water pollution caused by synthetic dye effluents that resist natural degradation has intensified the need for stable and environmentally sustainable photocatalytic materials. This study aimed to synthesize and characterize bilayer SiO₂/CuO thin films using silica extracted from rice husk ash (RHA) and to evaluate their photocatalytic activity for methylene blue (MB) degradation. Silica was extracted from agricultural RHA, activated with 1 M HCl, fabricated into thin films through sol–gel and spin-coating techniques, and thermally annealed at 300 °C. X-ray diffraction analysis confirmed the amorphous structure of silica, indicated by a broad diffraction hump centered at 2θ ≈ 22°, and the formation of monoclinic CuO crystalline phases in the bilayer films. Cross-sectional scanning electron microscopy showed that the pure SiO₂ film had a smooth morphology and a thickness of 3.507 µm, whereas the bilayer SiO₂/CuO film had a total thickness of 5.444 µm and exhibited a distinct porous upper layer comprising accumulated CuO grains deposited on the smooth SiO₂ base layer. Under UV-A irradiation, MB absorbance at λ = 664 nm decreased continuously, resulting in a degradation efficiency of 12.13% after 180 min. The degradation process closely followed pseudo-first-order kinetics, with a rate constant of 7.33 × 10⁻⁴ min⁻¹ and R² = 0.985. These findings demonstrate that biomass-derived silica from RHA can function as a supporting matrix for anchoring photocatalytically active CuO granular structures. This study contributes to the sustainable utilization of agricultural waste and provides a foundation for the further development of biomass-derived thin-film photocatalysts for synthetic dye degradation.

Abstract

Pumice is a silica-rich volcanic product that provides important information on magma characteristics and petrogenetic processes. This study aims to characterize the major and trace element geochemistry of Pumice from the Maninjau Caldera, West Sumatra. Pumice samples were analyzed to determine their major and trace element compositions and interpreted based on magma geochemistry. The results show that the Pumice is dominated by SiO₂ (75.33%) and Al₂O₃ (17.46%), whereas K₂O, Fe₂O₃, CaO, and TiO₂ occur in lower concentrations. Trace elements are dominated by Th, Rb, and Sr, while Zr, Y, and Nb occur in relatively low amounts. These geochemical characteristics indicate that the Pumice originated from felsic magma with rhyolitic to dacitic composition that experienced advanced magmatic differentiation through crystal fractionation, particularly of plagioclase. This study demonstrates that pXRF is an effective, rapid, efficient, and non-destructive method for preliminary geochemical characterization of volcanic rocks.
