Abstract

This study aims to analyze the concepts of physics found in the process of making hinggi kaworu ikat weaving. Hinggi Kaworu is a type of ikat weaving originating from Sumba Island in East Nusa Tenggara. This study uses a qualitative descriptive research method with an ethnophysical approach conducted in Prailiu Village, East Sumba Regency. Data was obtained from eight (8) weavers through observation, interviews, and documentation. The instruments used in this study were observation sheets, interview sheets, and documentation. Data analysis included data reduction, data presentation, and conclusion drawing. The results of the study show that the ikat weaving process consists of 11 stages, namely: 1) Pahulur; 2) Kabukul; 3) Pamening; 4) Karandi; 5) Hondu; 6) Ngiling; 7) Katahu; 8) Walahu; 9) Pameirang; 10) Pawunang; and 11) Kabakil. The main concepts identified include: 1) The principle of moment of force in the yarn winding process, 2) Tension in yarn unwinding, which affects the strength of the fabric, 3) Jurin's Law in the fabric dyeing process, 4) Pressure and Newton's Law in the cutting process.

Abstract

Penelitian ini bertujuan mendeskripsikan tingkat integrasi Sustainable Development Goals (SDGs) dalam pembelajaran fisika di SMA Kota Lhokseumawe serta hubungannya dengan sustainability awareness siswa. Menggunakan pendekatan kuantitatif-metode survei, data dikumpulkan dari 12 guru fisika (purposive sampling) dan 173 siswa (stratified random sampling) dengan angket tervalidasi. Integrasi SDGs diukur pada lima komponen (tujuan, materi, metode, media, penilaian), sedangkan sustainability awareness mencakup tiga dimensi (kognitif, afektif, perilaku). Hasil menunjukkan integrasi SDGs oleh guru berada pada kategori sangat baik (skor total 85), dengan kontribusi tertinggi pada materi(90,28), diikuti metode (86,11), tujuan (85,42), media (85,42), dan terendah penilaian (77,78). Rata-rata sustainability awareness siswa berada pada kategori baik (77,50), dengan urutan afektif tertinggi (80,00), kognitif (77,23), dan perilaku terendah (75,29), mengindikasikan adanya kesenjangan pengetahuan–sikap terhadap perilaku nyata (attitude–behavior gap). Uji korelasi Spearman memperlihatkan hubungan negatif lemah namun signifikan antara integrasi SDGs dan sustainability awareness (ρ = −0,271; p < 0,01). Temuan ini ditafsirkan sebagai indikasi ketidaksesuaian antara perencanaan dan implementasi, perbedaan indikator guru–siswa, serta minimnya asesmen autentik yang menilai aksi berkelanjutan. Kebaruan studi ini terletak pada analisis simultan yang menghubungkan tingkat integrasi guru dan sustainability awareness siswa secara komprehensif dalam konteks lokal Lhokseumawe—sebuah perspektif yang belum banyak dieksplorasi pada penelitian sebelumnya. Implikasi praktis menekankan penguatan strategi berbasis aksi (project/service learning kontekstual) dan penilaian autentik (portofolio proyek, rubrik sikap, jurnal refleksi) agar capaian kognitif–afektif terkonversi menjadi perilaku berkelanjutan. Studi lanjutan disarankan menguji jalur kausal secara longitudinal/eksperimental serta menyelaraskan konstruk pengukuran guru–siswa.

Abstract

Hydroxyapatite (HAp is widely known as a promising biomaterial because its chemical composition closely resembles that of human bone and teeth, making it suitable for biomedical uses such as bone tissue engineering and implant materials. This study explores how variations in calcination temperature (750–950 °C) affect the crystal structure and mechanical properties of HAp synthesized from Pinctada maxima shells—a calcium-rich biogenic waste. The crystal structure was analyzed using X-ray Diffraction (XRD), while mechanical properties were evaluated using a Tensilon testing machine. The XRD results showed a phase shift from the dominance of tricalcium phosphate (TCP) at low temperatures towards the dominant HAp phase at high calcination temperatures with improved crystallinity from 33.94% to 45.89%. The mechanical tests showed compressive strength values of 0.1981 to 0.3148 MPa and the elastic modulus of 14.941 to 26.721 MPa. The higher calcination temperature tends to increase the cristallinity, density, and compressive strength, but reduced elasticity due to a stiffer internal structure. These results indicate that changes in crystal structure have a direct effect on increasing the compressive strength and stiffnes of the material.  This study confirms the potential ofPinctada maxima shells as a sustainable calcium source for producing high-quality hydroxyapatite suitable for biomedical applications.

Abstract

This study aims to develop Augmented Reality (AR)–based learning media integrated into Kaffah Learning and to determine its feasibility, practicality, and effectiveness in enhancing meaningful learning and conceptual understanding among prospective teacher students. The research employed a Research and Development (R&D) approach using the ADDIE model, consisting of the stages of analysis, design, development, implementation, and evaluation. Expert validation was conducted to assess the media's feasibility, while practicality was measured through implementation observations and student response questionnaires. Effectiveness was evaluated using pretest–posttest results analyzed with N-Gain. The validation results show that the developed media meets the feasibility criteria with an average score of 89.75% (very feasible category). The practicality test obtained an average score of 88.33%, indicating that the media is highly practical and easy to use during the learning process. The effectiveness test produced an N-Gain value of 0.76 (high category), demonstrating a significant improvement in students’ conceptual understanding. The AR-based media also contributed to strengthening meaningful learning, particularly in indicators of personal relevance, clarity, and conceptual meaning. In conclusion, the AR-based Kaffah Learning media is declared feasible, practical, and effective for supporting physics learning for prospective teachers. The media successfully integrates scientific concepts, interactive visualization, and Islamic values, offering a meaningful and holistic learning experience aligned with 21st-century educational demands.

Abstract

This study aims to develop a physics teaching module based on Kaffah Learning and to examine its feasibility and effectiveness in improving high school students’ creative thinking skills. The development process employed the 4D model (Define, Design, Develop, and Disseminate). The Define stage included needs analysis through curriculum review and teacher interviews. In the Design stage, a module draft was constructed by integrating holistic values, contextual learning activities, and creative problem-solving tasks. The module was validated by material and media experts using a standardized feasibility assessment instrument. Quantitative data were analyzed using Aiken’s V index and the N-Gain test derived from pretest and posttest scores. The validation results indicated that all aspects of the module content appropriateness, language clarity, presentation, and graphical design achieved an Aiken’s V value of 0.83, categorized as highly feasible. A limited trial conducted with students at SMAN 3 Mataram showed an increase in the average score from 60 to 88 after using the module. The N-Gain analysis yielded a value of 0.38 (moderate category), indicating that the module effectively enhanced students’ creative thinking skills, although the improvement had not reached a high category. The application of Kaffah Learning was found to encourage idea exploration, reflection, and the integration of physics concepts with real-life contexts.This study concludes that the physics teaching module based on Kaffah Learning is highly feasible and reasonably effective in improving students’ creative thinking skills. These findings provide a foundation for further development of holistic learning materials in other physics topics.

Abstract

This study presents a computational visualization of the stationary states of a particle confined in a one-dimensional infinite potential well, formulated entirely from analytical solutions and implemented in a cloud-based Python environment. Using Google Colab, wave functions, probability densities, and nodal structures were generated for several quantum numbers to illustrate fundamental quantum-mechanical characteristics, including energy quantization, spatial oscillatory behavior, and the emergence of classical correspondence at higher energy levels. The resulting visualizations offer a clear representation of the spatial distribution of quantum states, thereby supporting a conceptual understanding of the underlying analytical model. As a novelty, this study introduces a Colab-based analytical–numerical combination as a visualization medium, a format rarely explored in depth in quantum-well learning contexts. Beyond instructional applications, the modeled system accurately reflects the essential physical behavior of electrons in semiconductor quantum wells, where quantized subband energies and wave-function profiles significantly influence optical and electronic transitions.  These findings demonstrate that analytically derived quantum models, when integrated with computational visualization, can effectively enhance conceptual comprehension while offering insight into the fundamental principles governing modern optoelectronic structures.

Abstract

Magnetic Resonance Imaging (MRI) is widely used to evaluate spinal pathology, with image quality strongly influenced by acquisition parameters such as the Field of View (FOV). This study investigates the effect of small FOV adjustments on the Signal-to-Noise Ratio (SNR) and Contrast-to-Noise Ratio (CNR) in axial T2-weighted Fast Spin Echo (FSE) lumbar spine MRI. This study offers one of the quantitative evaluations of clinically realistic FOV variations, addressing a gap between routine protocol adjustments and evidence-based image quality optimization. This experimental study prospectively examined thirty patients undergoing routine lumbar spine MRI using a Philips Ingenia CX 1.5T system. Axial T2-weighted FSE images were acquired with three FOV settings (170 mm × 170 mm, 190 mm × 190 mm, and 210 mm × 210 mm), while all other imaging parameters were kept constant. Image quality was assessed by measuring mean signal intensities in standardized regions of interest (ROIs) placed in the intervertebral disc, cerebrospinal fluid (CSF), and surrounding fat tissue, from which SNR and CNR were calculated and statistically compared across FOV settings. The results showed increasing trends in SNR and CNR with larger FOV values; however, these differences were not statistically significant (p > 0.05), indicating that small FOV enlargements produce minimal voxel size changes and negligible effects on image quality. Clinically, these findings suggest that minor FOV adjustments can be safely applied to accommodate patient anatomy or positioning without compromising image quality, while larger FOV changes are required to achieve meaningful improvements in SNR and CNR.

Abstract

Selat Sunda memiliki peran oseanografi yang strategis karena menghubungkan Laut Jawa dengan Sumatera melalui Selat Sunda. Metode yang digunakan meliputi pemanfaatan data batimetri GEBCO dan data arus reanalysis CMEMS periode 1993–2020, ekstraksi profil vertikal arus zonal dan meridional hingga kedalaman 60 m, serta analisis korelasi Pearson antara kecepatan arus dan kedalaman dengan tujuan untuk menganalisis kontribusi kedalaman dasar laut terhadap karakteristik arus laut musiman secara spasial dan vertikal di Selat Sunda, serta mengkaji hubungan linier antara kedalaman dan kecepatan arus pada skala multi-musim. Hasil penelitian menunjukkan bahwa variasi kedalaman laut memberikan pengaruh signifikan terhadap dinamika arus musiman, ditunjukkan oleh korelasi negatif yang konsisten antara kedalaman dan kecepatan arus pada seluruh musim. Pada musim JJA, pengaruh Muson Tenggara menghasilkan lapisan campuran yang tebal hingga sekitar ±40 m dengan struktur arus yang relatif homogen dan magnitudo tertinggi (≈0,7–0,8 m/s). Sebaliknya, musim DJF memperlihatkan struktur arus yang lebih kompleks dan bersifat baroklinik, ditandai oleh pembalikan arah antara lapisan permukaan dan lapisan bawah. Secara keseluruhan, interaksi antara morfologi dasar laut, sistem monsun, dan proses hidrodinamika regional memainkan peranan penting dalam membentuk variabilitas arus di Selat Sunda. Temuan ini memiliki implikasi penting bagi pengembangan kajian oseanografi fisis serta dapat menjadi dasar ilmiah dalam mendukung perencanaan keselamatan pelayaran, pengelolaan wilayah pesisir, dan mitigasi risiko kelautan di Selat Sunda.

Abstract

The collaboration between computation, theory, and experiment has been a game-changer for academia. This work considers computational physics as an integrative discipline across the natural sciences and utilizes a narrative literature review organized with a conceptual and methodological synthesis. Using peer-reviewed literature from physics, chemistry, biology, and environmental science, as well as science education, the work identifies common interdisciplinary numerical approaches, computational techniques, and algorithms used in modeling and simulation. The research demonstrates that while computational practices in research and education have evolved separately across various fields, the core techniques that have been and continue to be most important for modeling across many fields are those rooted in computational physics: finite difference, finite element, and finite volume methods. Furthermore, the synthesis demonstrates that the combination of modeling in physics and the use of machine learning and other data-driven methods, as well as the importance of computational thinking, are essential for interdisciplinary science and science education. Model formulation, discretization, numerical approximation, algorithm implementation, and data visualization are core components of a generalized computational modeling framework. While this study has provided a unified conceptual framework for multiple academic domains and interdisciplinary curriculum development, its reliance on previously established literature, coupled with the lack of primary empirical findings or simulations, is a notable limitation. This study frames the discipline of computational physics as a methodology, rather than as a field of study with clear boundaries.
