Abstract

Abstract The purpose of this study is to determine the terminal velocity and fluid viscosity using falling ball viscometer with video tracker application. The terminal velocity is obtained by videoing the ball falling into a tube 115 cm long and 5 cm in diameter which has been filled with fluid and then the video is analyzed using tracker application. The fluids used are oil SAE 20W-50 and glycerin. The balls used are namely as balls I, II, and III with diameters of 1,09cm, 1,56cm, and 1,57cm. Once the terminal velocity of the sphere is known, the fluid viscosity is obtained by using Stokes law principle. The terminal velocities of balls I, II, and III in oil SAE 20W-50 are 0.247m/s, 0.250m/s, and 0.187m/s, while the terminal velocities of balls in glycerin are 0.092m/s, 0.090m/s, and 0.065m/s. The average fluid viscosity of oil SAE 20W-50 and glycerin are 0,834Ns/m2 and 1,807Ns/m2.

Abstract

This study aims to analyze the feasibility and effectiveness of experiment media based on Internet of Things (IoT) to enhance the students' HOTS ability on thermodynamics law material. This Research and Development comprises of the following stages: (1) defining needs, (2) designing products, (3) developing products, and (4) disseminating products. Four expert lecturers and two physics teachers serve as the validator. The limited trial subjects consisted of six students of class XI MIPA SMAN 1 Pekalongan; the field test subjects consisted of 108 students who were randomly selected from all XI MIPA classes at SMAN 2 Batang, and the disseminating subjects were teachers of MGMP physics in Batang. The instruments used were expert validation questionnaires, teacher response questionnaires, student response questionnaires, and written tests. The results of the validation of media experts were 3.81 (very good), and material experts were 3.54 (very good). Meanwhile, the results of teacher responses were 3.92 (very good), and the results of student responses were 3.50 (very good). The effective contribution of the IoT-based experimental media to improve the ability of HOTS can be seen from the results of the Multivariate Test analysis on GLM based on the partial eta squared value of 85.9%. This shows that experiment media based on IoT is feasible and effective to enhance the students’ HOTS ability.

Abstract

Post-pandemic digital transformation in education requires pre-service science teachers to have strong digital competencies. However, previous studies remain fragmented and have not fully integrated digital learning models with digital competence development. This study aims to map global research trends, identify the intellectual structure, and explore research gaps in this field. A quantitative bibliometric approach was conducted using Scopus-indexed publications from 2020–2025. A total of 30 documents were selected through the PRISMA procedure and analyzed using Bibliometrix (R). The findings show an increasing publication trend, especially in 2021 during the global shift to digital learning. Research was mainly dominated by Asian and European countries, while contributions from developing countries remained limited. Major themes included TPACK, pedagogical innovation, pre-service teacher education, and 21st-century competencies. However, the connection between digital learning design and digital competence development is still limited. This study emphasizes the need for an integrative and sustainable digital learning framework to support the transformation of science teacher education.

Abstract

This study is a preliminary investigation aimed at mapping the profiles and dynamics of students’ digital competencies based on the five domains of the Digital Competence Framework (DigComp): Information & Data Literacy, Communication & Collaboration, Digital Content Creation, Security & Safety, and Educational Problem Solving. This study employs a quantitative descriptive approach using an observational method involving 195 high school students selected through purposive sampling via the Google Forms platform, as well as 66 university students from 12 public and private universities. The research instrument consists of a Likert-scale-based observation sheet validated using the Rasch Model (Rating Scale Model) with the assistance of Winsteps software. Overall, students’ digital competencies fall into the “fairly good” category. The Security & Safety and Communication & Collaboration dimensions showed the highest levels of achievement, while Digital Content Creation ranked the lowest. The pattern of digital competency development shows an upward trend in higher grade levels, although not in a linear fashion. These findings indicate that students are still predominantly technology users and have not yet reached their full potential as digital creators. Therefore, there is a need to strengthen project-based learning and pedagogical innovations closely linked to digital skills to develop digital competencies more comprehensively and sustainably as part of efforts to support the 21st-century Global SDGs program.

Abstract

This work investigated the effect of post-annealing treatment on the fabrication of zinc oxide (ZnO) thin film by spraying deposition method. Based on SEM analysis, the annealed ZnO thin film at 400˚C presented better uniformity as compared to the non-annealed film. Further measurement by UV-Vis revealed that the lowest optical band gap energy (Eg) (3.22 eV) was achieved by 400˚C sample. These results confirmed that post-annealing treatment enhanced the optical and morphological properties of the fabricated ZnO thin film.

Abstract

The students have had problems in forming a proper understanding of the concept of elasticity in terms of integrating numbers, graphs, and mathematics in understanding the relationship between force and deformation. This study was designed to investigate the effect of IoT-based real-time representation on the conceptual understanding of elasticity. A quasi-experimental design was used by taking a non-equivalent control group from eleventh graders. While the experimental group went through an IoT-based practicum in which they were able to visualize real-time numerical and graphical representations, the control group followed the standard practice in the laboratory. The test of conceptual understanding of the students involved the use of a diagnostic reasoning instrument, and the analysis of covariance was applied in analyzing the gathered data. The results showed that the use of IoT-based representation improved students’ conceptual understanding of elasticity more than traditional classroom learning.

Abstract

Global demand for fossil energy continues to increase, affecting both the environment and energy availability. This study aims to describe the energy crisis and its impacts, the adoption of renewable energy (RE), and the educational challenges in addressing these problems in Indonesia.  The Systematic Literature Review method was conducted using Harzing’s Publish or Perish application, which indexed articles from Scopus and Google Scholar, using the keywords “energy crisis,” “renewable energy,” “energy education Indonesia,” and “impact of fossil energy.” The review covered publications from 2017 to March 2025. A total of 116 articles met the eligibility criteria. The results indicate that the environmental impacts include increases in CO2 emissions driven by urbanization, industrialization, and transportation. Globally, RE adoption remains at only 1%. The use of renewable energy in Indonesia is relatively low, at 11.31% of the available energy supply. Indonesia’s educational strategies include establishing specialized schools for the development of RE, curriculum support, and implementing project-based learning. These strategies must be replicated and further developed by other institutions. Through these efforts, Indonesia is expected to become more aware of the limitations and impacts of fossil energy and better able to utilize the availability of renewable energy.

Abstract

This study developed and validated a science learning model integrating Science, Technology, Engineering, and Mathematics (STEM) with the Research Skill Development (RSD) framework to strengthen students’ research skills. A two-round Delphi study was conducted with experts to establish consensus on the model. The first round generated a conceptual synthesis through qualitative thematic analysis, while the second evaluated expert agreement using Aiken’s V. Experts reached strong consensus on the model structure, the central role of science, integration of the engineering design process, contextual problem-based learning, and progressive research stages. The proposed model has high content validity and provides a systematic framework for developing research skills, supporting student independence, and strengthening research-oriented science learning across higher education contexts.
