Abstract

Fe₃O₄ nanoparticles were synthesized via a green route using Pleomele angustifolia leaf extract as a bio-reducing and capping agent. XRD analysis confirmed the structure of pure cubic spinel magnetite phase with nanoscale crystallite sizes, while slight lattice variations indicate surface interactions with phytochemicals. SEM images revealed quasi-spherical nanoparticles with average particle sizes of 53–63 nm, where increasing extract concentration reduced agglomeration and improved dispersion. FTIR spectra showed characteristic Fe–O vibrations together with hydroxyl, carbonyl, and aliphatic functional groups, confirming effective surface functionalization by plant-derived compounds. These results demonstrate that Pleomele angustifolia extract regulates nucleation, growth, and surface chemistry during Fe₃O₄ nanoparticle synthesis, highlighting its potential as a sustainable synthesis route for magnetic nanomaterials.

Abstract

Southern Karangasem Regency, Bali, is located in a tectonically active zone and requires detailed local scale earthquake hazard assessment. This study aims to develop an earthquake hazard microzonation map for Bungaya, Padang Kerta, Tiyingtali, and Ababi villages by integrating microtremor analysis and seismic source modeling. Single-station microtremor measurements were analyzed using the Horizontal-to-Vertical Spectral Ratio (HVSR) method to obtain dominant frequency (f0), amplification factor (A0), and seismic vulnerability index (Kg). Peak Ground Acceleration (PGA) was estimated based on modeled earthquake sources affecting the study area. The results show that f0 values range from 0.51–8.78 Hz, A0 values from 0.8–7.46, and Kg values from 0.78–14.86, indicating varying local site conditions. The estimated PGA ranges from 157 to 171 gals, corresponding to VI–VII on the MMI scale. The spatial distribution of these parameters reveals significant variation in earthquake hazard levels across the southern Karangasem region. The novelty of this study lies in the integration of HVSR-derived site response parameters with PGA modeling to produce a detailed village-scale microzonation map. The results provide valuable implications for seismic risk mitigation, spatial planning, and earthquake-resilient infrastructure development in seismically active regions.

Abstract

Critical thinking skills are essential in physics education, particularly in understanding abstract concepts like wave functions in quantum mechanics. However, traditional teaching methods often fail to foster these skills effectively. This study explores the use of an interactive e-module titled Quantum Physics: Wave Function to enhance critical thinking skills among students in a physics education program. A quasi-experimental design was employed with an experimental group using the e-module and a control group following conventional methods. Pretest and posttest results showed a significant improvement in critical thinking skills for the experimental group (average increase: 26.30) compared to the control group (average increase: 11.70). Statistical analysis confirmed the e-module's effectiveness (t = 2.95, p = 0.01). The e-module fostered active participation, problem-solving, and independent exploration, demonstrating its potential to improve critical thinking and engagement in complex physics topics. These findings highlight the value of integrating technology into physics education to enhance learning outcomes.
