Abstract

Penelitian ini bertujuan untuk mengetahui pengaruh dan peningkatan menggunakan model problem based learning terhadap keterampilan berpikir kreatif fisika siswa. Penelitian ini dilakukan pada siswa kelas X SMA. Variabel pada penelitian ini adalah keterampilan berpikir kreatif dan model Problem-Based Learning. Instrument penelitian menggunakan test dalam bentuk essay dengan jumlah 7 soal yang telah dinyatakan valid. Hasil uji analisis covariate menunjukkan lebih kecil dari 0,05, yang berarti terdapat perbedaan keterampilan berpikir kreatif yang diajarkan menggunakan model PBL. Model Problem-Based Learning meningkatkan keterampilan berpikir kreatif lebih baik dibandingkan pembelajaran konvensional. Penggunaan model PBL dapat meningkatkan keterampilan berpikir kreatif kecuali pada indikator berpikir flexibility.

Abstract

This research aims to develop a three-tier diagnostic test instrument to identify misconceptions in fluid physics among grade XI students at SMAN 2 Medan. Misconceptions are a persistent barrier in learning physics and require specific instruments for accurate identification. The developed instrument includes multiple-choice questions (first tier), reasoning options (second tier), and confidence levels (third tier) to assess students' conceptual understanding comprehensively. Using the 4D (Define, Design, Develop, Disseminate) development model, the instrument underwent validation by experts, small-scale, and large-scale trials. The results indicated that the diagnostic test instrument is valid and reliable, effectively identifying students' misconceptions in fluid concepts such as hydrostatic pressure, Archimedes' principle, Pascal's law, and Bernoulli's principle. This instrument not only aids teachers in recognizing areas that need instructional emphasis but also contributes to improving learning strategies. The findings revealed a significant portion of students experienced misconceptions, highlighting the need for targeted pedagogical interventions. This study contributes to physics education by offering a practical diagnostic tool to improve conceptual learning and reduce misconceptions.

Abstract

After inquiry learning research is carried out, it is necessary to investigate problems and find problems based on clear concepts based on observations. Creativity is the ability to create something new. The proposed activities are based on physical phenomena through experiments. Prior knowledge of a problem may detract from an investigation, as it may prefer to retain known evidence rather than devise new alternatives. Creativity is the ability to think to come up with solutions, ideas, ways, products as solutions to existing problems. Innovative is the process of doing something in a new way. The process skills of discovering and developing concepts, theories, legal principles and facts are science process skills (KPS). Based on investigations and problem findings, creative inquiry learning with a process skills approach is used. The method in this research is analysis of indicators of inquiry learning syntax (problem formulation, hypothesis formulation, data collection, hypothesis testing and conclusions), creativity (KE experimental group and KK control group) and science process skills (KE and KK). The concepts developed mutually support inquiry, creativity and process skills. Students' ability to investigate and find problems can be realized.

Abstract

Penelitian ini bertujuan untuk melihat pengaruh multimedia interaktif yang berbasis web google sites terhadap literasi digital dan hasil belajar fisika siswa pada materi Fluida Statis di kelas XI IPA SMA. Jenis penelitian ini quasi eksperimen. Populasi penelitian ini seluruh kelas XI IPA SMA Katolik Mariana Medan T.A 2023/2024 yang terdiri dari 2 kelas ( 56 orang) . Sampel penelitian ini terdiri dari 2 kelas yaitu kelas XI IPA-1 (kelas eksperimen) dan kelas XI IPA-2 (kelas kontrol) yang diambil dengan teknik sampling jenuh, masing – masing kelas berjumlah 28 orang. Instrumen tes yang digunakan berbentuk pilihan berganda yang masing – masing mengukur tes hasil belajar fisika siswa dan angket sebagai pengukur peningkatan literasi digital siswa. Teknik analisis data yang digunakan dengan uji manova dan N-gain. Nilai rata – rata pretes hasil belajar kelas eksperimen sebesar 37,71 dan pada kelas kontrol 34,29. Nilai rata – rata pretes literasi digital kelas eksperimen sebesar 74,57 dan pada kelas kontrol 52,86. Nilai rata – rata postes hasil belajar fisika siswa pada kelas eksperimen sebesar 76,14 dan pada kelas kontrol 56,71. Nilai rata – rata literasi digital pada kelas eksperimen sebesar 93,14 dan pada kelas kontrol 67,25. Bedasarkan hasil penelitian diperoleh rata – rata postes kelas eksperimen lebih besar dibanding kelas kontrol. Hasil uji manova data postes menunjukkan adanya perbedaan yang signifikan yang berarti terdapat pengaruh multimedia interaktif berbasis web google sites terhadap literasi digital dan hasil belajar fisika siswa. Peningkatan N-gain literasi digital pada kelas eksperimen 0,72 (tinggi) dan N-gain hasil belajar fisika siswa pada kelas eksperimen 0,61 (sedang).

Abstract

Bimetallic nanoparticles offer enhanced antibacterial properties due to synergistic effects between different metal ions. In this study, Ag-Cu nanoparticles were synthesized using a chemical reduction method with NaBH₄ as the reducing agent and PVP as a stabilizer. The resulting nanoparticles showed a greenish-black color and an average particle size of 308.8 nm with narrow distribution. Antibacterial activity against Escherichia coli was tested using the disc diffusion method at concentrations of 5%, 10%, and 15%. The results showed a concentration-dependent increase in inhibition zones, with a maximum average of 7.8 mm. Although lower than the positive control, the findings confirm the potential of Ag-Cu nanoparticles as alternative antibacterial agents. Further optimization is recommended for biomedical applications.
