Simulasi Komputasional untuk Meningkatkan Efisiensi DSSC Berbasis TiO₂/Cu: Studi Ketebalan dan Suhu Fotoanoda
No full textIn order to address the growing energy demands in Indonesia, this study investigates the enhancement of TiO₂/Cu-based Dye-Sensitized Solar Cells (DSSCs) efficiency through computational simulation. The research focuses on the influence of photoanode thickness and operational temperature on the device’s performance. The simulation results revealed that an optimal photoanode thickness of 2.60 μm achieved the highest efficiency of 8.493%, balancing light absorption and electron transport. Additionally, an operational temperature of 350 K was found to yield the maximum efficiency of 9.376%, as higher temperatures reduce electrolyte viscosity, improve ion mobility, and minimize charge recombination. Validation of the simulation model was conducted by comparing it with experimental data from prior studies, ensuring its reliability in representing charge transport phenomena in DSSCs. These findings offer crucial insights for designing cost-effective, efficient, and sustainable DSSCs suitable for Indonesia’s abundant solar energy resources. Further research is recommended to explore the interaction of additional components and external factors to enable commercial scalability of this technology.Untuk mengatasi permintaan energi yang terus meningkat di Indonesia, penelitian ini menyelidiki peningkatan efisiensi Sel Surya Tersensitisasi Pewarna (DSSC) berbasis TiO₂/Cu melalui simulasi komputasional. Penelitian ini berfokus pada pengaruh ketebalan fotoanoda dan suhu operasional terhadap kinerja perangkat. Hasil simulasi mengungkapkan bahwa ketebalan fotoanoda optimal 2,60 μm mencapai efisiensi tertinggi sebesar 8,493%, yang menyeimbangkan penyerapan cahaya dan transpor elektron. Selain itu, suhu operasional 350 K ditemukan menghasilkan efisiensi maksimum sebesar 9,376%, karena suhu yang lebih tinggi mengurangi viskositas elektrolit, meningkatkan mobilitas ion, dan meminimalkan rekombinasi muatan. Validasi model simulasi dilakukan dengan membandingkannya dengan data eksperimen dari penelitian sebelumnya, untuk memastikan keandalannya dalam merepresentasikan fenomena transpor muatan dalam DSSC. Temuan ini menawarkan wawasan penting untuk merancang DSSC yang hemat biaya, efisien, dan berkelanjutan yang sesuai untuk sumber daya energi surya Indonesia yang melimpah. Penelitian lebih lanjut disarankan untuk mengeksplorasi interaksi komponen tambahan dan faktor eksternal guna memungkinkan skalabilitas komersial teknologi ini.

No full textThis study aims to analyze the effectiveness of the implementation of the Jigsaw type cooperative learning model assisted by Genially media in improving the activity and learning outcomes of fifth grade students of Triharjo Elementary School in the subject of science. This study uses the Classroom Action Research (CAR) method with the Kemmis and McTaggart model which is carried out in two cycles at Triharjo Elementary School, Sleman, to improve the activity and learning outcomes of fifth grade students in the subject of science. Data were collected through observations of student learning activities using observation sheets and multiple-choice tests of 20 questions that have been validated by material experts. The success of this study was determined based on an increase in student activity that reached a minimum of 75% and student learning outcomes that met the achievement criteria of 80% with a minimum score of 75. This study shows that the implementation of the Jigsaw type cooperative learning model assisted by Genially media is effective in improving the activity and learning outcomes of fifth grade students of Triharjo Elementary School in the subject of science. Before the action, student participation and learning outcomes were still low, but after the implementation of this model, there was a significant increase, especially in Cycle II with an average learning outcome reaching 77.71%. This learning model has been proven to increase student motivation, engagement, and understanding, making it a more effective alternative learning method
Systematic Literature Review: Analysis of Students' Reasoning Ability and Difficulties in Newton's Law Material
No full textThis study aims to identify students' reasoning abilities and learning difficulties related to Newton's Laws through a systematic literature review using the PRISMA method. The review analyzes seven scientific articles published between 2020 and 2024 in SINTA-accredited journals, international conference proceedings, and Scopus-indexed sources. The findings indicate that students’ reasoning abilities regarding Newton's Law are still low, with an average conceptual understanding of only 33.3%. Common difficulties faced by students include interpreting Newton's First Law (inertia and constant velocity), understanding the relationship between force, mass, and acceleration in the Second Law, and the action-reaction principle in the Third Law. These difficulties are generally caused by the abstract nature of the concepts and students’ weak logical reasoning skills. The review also highlights the need for effective instructional strategies. Contextual teaching, problem-solving-based learning models, and metaphorical thinking approaches are proposed as potential solutions. These strategies are considered effective in enhancing students’ conceptual understanding and scientific reasoning abilities when implemented appropriately. The findings provide valuable insights for educators to design more targeted instructional interventions and contribute to improving learning outcomes in physics education, particularly in Newtonian mechanics

Development of Metacognition-Based LKPD to Improve Conceptual Understanding in Reaction Rate Material
No full textThe importance of constructivism-based chemistry learning is to develop students' conceptual understanding and metacognitive skills through active engagement, with the teacher as a facilitator, to create critical, independent, and globally competitive graduates. This study aims to develop Student Worksheets (LKPD) focused on metacognitive skills in learning reaction rate material, with the expectation of improving students' conceptual understanding and learning outcomes. Based on validation results, the LKPD has proven to be feasible for use, particularly in terms of language and metacognitive skills. In the first validation stage, the LKPD achieved an average percentage of 54.35%, which falls into the "feasible" category, while in the second stage, there was a significant improvement with an average percentage of 73.05%. Practicality assessments from teachers and students showed very good results, with teacher and student questionnaire scores ranging from 3.76 to 3.82 and 76.53% to 77.63%, respectively. Effectiveness evaluation through limited and wide trials indicated a significant improvement in conceptual understanding, with average posttest scores reaching the mastery category after using the metacognition-based LKPD. The improvement in conceptual understanding, calculated using the n-gain, showed a "moderate" category, with an average n-gain value of 0.60 for the limited trial and 0.63 for the wide trial. These results prove that the metacognition-based LKPD is effective in improving students' understanding and learning achievements in reaction rate material and can be used as an alternative in chemistry learning to develop students' higher-order thinking skills.Abstrak: Penelitian ini bertujuan untuk mengembangkan Lembar Kerja Peserta Didik (LKPD) yang berfokus pada keterampilan metakognisi dalam pembelajaran materi laju reaksi, dengan harapan dapat meningkatkan pemahaman konsep dan hasil belajar siswa.
