Abstract

The need for clean water is a necessity to sustain human life. This need will continue increasing in line with the human population growth, but it is not balanced by appropriate wastewater treatment to preserve the clean water stock. Zirconia and titania-based membrane technology is a promising technology in water and waste treatment processes because it is able to produce a good and stable quality of water against chemical reactions, high temperatures, and mechanical stress. This study aims to literature study-based analyze the capability of synthesis, characterization, and application of a membrane that combines zirconia and titania (Zr1-xTix)O2 with Al2O3 as a substrate for domestic wastewater treatment. The discussion describes the method of zirconia.titania membrane application to support its performance in domestic wastewater treatment.

Abstract

Instructional aids will made student easier to understanding and applying physics concepts. This study aims to obtain data and analyze the student’s needs toward to the instructional ais soil moisture measurement in physics lesson. Samples in study were student of 33 peoples, taken from class XH at SMAN 71 Jakarta with technique purposive sampling. This study resulted: physics learning motivation of student are in the medium category, with attention 87.88%, relevance 55.30%, confidence 60.61% and satisfaction 87.12%. Curriculum analysis show in class X, measurement lesson still can be developed to soil moisture measurement based on contextual learning approach. Based on style learning, 4,48% students who have visual learning style, auditory 24.24% and kinesthetic 27.27%. A total of 59.85% students experience difficulty in learning physics. As many as 79.55% of students agree that hands on method in learning can reduce difficulty in learning physics. As many as 87.12% of students agree that they need automated instrument in physics practice and only 39.39% of students has known about Arduino. The frequently used learning media in class were on audio-visual category, starting from power point slide presentation, Canva’s slides presentation, video, simulation and animation. All of those findings were supported research and development of oto-sprinkler system by using humidity sensor and Arduino Uno. Result of this study will become the base contextual in developing contextual teaching aids in form of soil moisture measurement, so that can increase the physics learning motivation in student.

Abstract

Motivation and physics learning outcomes among students remain low. One approach to improving both aspects is the use of contextual teaching assisted by PhET. This study aims to determine whether and to what extent the application of the contextual teaching and learning model assisted by PhET influences students' motivation and physics learning outcomes. This research employs a quantitative quasi-experimental method and was conducted at SMA Negeri 71 Jakarta, with samples selected through purposive sampling. The instruments used include a questionnaire to measure learning motivation and a test to assess learning outcomes on Ohm's law, resistor circuits, and Kirchhoff's first law. Hypothesis testing using an independent sample t-test resulted in a significance value of 0.000 < 0.05, indicating a significant effect of PhET-assisted contextual learning on motivation and learning outcomes. The effect size analysis showed values of 0.289 for motivation and 0.655 for learning outcomes, categorized as moderate and high, respectively. Thus, it can be concluded that PhET-assisted contextual learning has a moderate impact on motivation and a strong influence on learning outcomes.

Abstract

Renewable Energy based Hands-on experimental kits are essential for enhancing student engagement and conceptual understanding in physics education. This study evaluates the feasibility of a Solar-Powered Direct Current (SP-DC) experimental kit, focusing on its effectiveness, relevance, and endurance as perceived by users. A quantitative design was employed using a closed-ended questionnaire comprising 14 items. Participants (n=79) consisted of undergraduate students from Universitas Kristen Indonesia (n=36) and high school students from SMA N 11 Jakarta (n=43). Prior to completing the questionnaire, students engaged in assembling the SP-DC kit and measuring current and voltage. Data were collected between June 2022 and June 2023 and analyzed using the Rasch model through Winstep version 5.9.00. Fit validity was determined by item and person statistics (MNSQ, ZSTD, PTMEA), while descriptive analysis included item measures and score distributions. Findings confirmed that all questionnaire items met Rasch model validity criteria, with PTMEA correlations above 0.7. In terms of effectiveness, participants reported favorable perceptions of ease of use and assembly, though aspects such as portability and storage required improvement. Relevance was demonstrated through the kit’s role in supporting understanding of series and parallel circuits, motivating interest in renewable energy, and strengthening connections between theory and practice. Endurance analysis revealed that the kit was generally durable and safe, though operational robustness could be enhanced. The SP-DC experimental kit is a feasible educational tool that supports effectiveness, curricular relevance, and endurance. These results suggest the kit’s potential for broader application in both secondary and higher education.
