Abstract

This study aims to develop an Agrophysics e-module using the Articulate Storyline application and to evaluate its validity and feasibility as a teaching material to support sustainable industrial agriculture. A research and development method based on the 4D model was employed, encompassing the define, design, and develop stages. The research instruments included material and media expert validation sheets as well as user response questionnaires. Validation was conducted by three experts, and user trial responses were collected from 28 students. The data were analyzed using descriptive statistical techniques. The results of the material expert validation yielded an average score of 3.63, categorized as highly feasible, while media validation produced an average score of 3.33, also classified as highly feasible. Preliminary trial results indicated user responses with an average score of 3.70, falling within the highly feasible category. Consequently, the Agrophysics e-module was deemed feasible for use as a teaching material. The module was designed to integrate recent developments in the application of physics concepts in agriculture. Therefore, the developed e-module contributes to multidisciplinary physics learning within the context of supporting sustainable industrial agriculture.

Abstract

This study aimed to evaluate the effectiveness of the Physics TPE program in improving teacher professionalism by considering the perceptions of its graduates. Data were collected through a self-assessment questionnaire/survey given to Physics TPE graduates regarding their teacher professional competence before and after participating in TPE. A total of 36 physics TPE graduates participated in this study. The results showed significant improvements in various aspects of teacher professionalism. Graduates reported improvements in their mastery of educational foundations, teaching program preparation, teaching program implementation, assessment, and student character building. In particular, the greatest improvement was observed in mastery of educational foundations, likely due to the alignment of the TPE curriculum with the stages of effective teaching. While teaching implementation showed the smallest improvement, it was still positive. Overall, the Physics TPE program was perceived well by its graduates, indicating its potential to contribute to the professional development of physics teachers.

Abstract

Wilayah Jawa Timur–Bali–NTB merupakan zona subduksi aktif dengan tingkat aktivitas seismik tinggi akibat interaksi Lempeng Indo-Australia dan Eurasia. Kompleksitas tektonik di wilayah ini menyebabkan pola seismisitas yang heterogen sehingga diperlukan pendekatan analisis yang mampu mengidentifikasi zona potensi bahaya seismik secara lebih representatif. Penelitian ini bertujuan mengidentifikasi zona potensi bahaya seismik melalui integrasi klasterisasi spasio-temporal dan distribusi b-value. Data yang digunakan berupa 1168 kejadian gempa bumi dari katalog BMKG, GFZ, dan USGS periode 1994–2024 dengan magnitudo Mw ≥ 4 dan kedalaman ≤ 300 km. Analisis seismisitas dilakukan menggunakan algoritma K-Means dan ST-DBSCAN, kemudian diintegrasikan dengan analisis distribusi b-value. Hasil menunjukkan kedua algoritma menghasilkan empat klaster, namun ST-DBSCAN memberikan kualitas klasterisasi yang jauh lebih baik dengan Silhouette Score 0,866 (K-Means: 0,410) dan Davies-Bouldin Index 0,300 (K-Means: 0,983). STDBSCAN mengklasifikasikan 83,9% data sebagai outlier, menunjukkan kemampuan yang lebih efektif dalam memisahkan noise dari aktivitas seismik terkonsentrasi. Integrasi klaster dengan distribusi b-value mengungkapkan bahwa tiga klaster ST-DBSCAN terkonsentrasi di zona subduksi Selatan Jawa Timur dengan b-value rendah (0,812-0,981) dan pola occasional, mengindikasikan akumulasi stres tektonik tinggi dan berpotensi menghasilkan gempabumi bermagnitudo besar. Satu klaster di zona Patahan Naik Busur Belakang Flores (b-value: 0,831) memiliki pola stationary yang berkaitan dengan aktivitas aftershock/swarm. Penelitian ini menunjukkan bahwa pendekatan terpadu antara klasterisasi spasio-temporal dan distribusi b-value mampu memberikan interpretasi yang lebih komprehensif dibandingkan penggunaan metode tunggal dalam analisis bahaya seismik, sekaligus mendukung prioritas monitoring dan mitigasi aktivitas gempa di wilayah Jawa Timur–Bali–NTB.

Abstract

The hydrogen atom is a fundamental system in quantum mechanics, yet studies that integrate the effective potential structure, radial probability distribution, and radial node patterns remain limited. This study aims to characterize the interrelationship of these three aspects through a computational approach. The method used is a combination of analytical solutions to the radial Schrödinger equation and numerical evaluation to calculate and visualize the effective potential, radial wave functions, and probability distributions. Furthermore, radial nodes are identified using a combination of the principal quantum number n and the azimuthal quantum number l. The results show that variations in l modify the topology of the effective potential through centrifugal resistance, while an increase in n broadens the probability distribution according to the scaling law . The radial node pattern follows the relation , indicating an interaction between radial excitation and angular momentum. Overall, the probability distribution and radial nodes are direct consequences of the effective potential structure. This study provides a unified analytical framework for comprehensively understanding the radial structure of hydrogenic systems.
