Abstract

The natural exploration approach (JAS) is used to utilize the surrounding natural environment as an object of knowledge. The purpose of this study was to determine the effect of the JAS approach on wave material on student learning outcomes. This study used a quasi-experimental method with a nonequivalent control group design. The results showed that the experimental class produced an average pretest score of 6.14, and after learning using the natural exploration approach (JAS), the average posttest score was 63.66. The control class had an average pretest score of 4.42 and an average posttest score of 40. A statistical analysis using an independent sample t-test obtained a significance value (2-tailed) of 0.001 <0.05, thus rejecting and accepting . Based on the results, it can be stated that the use of the natural exploration approach (JAS) has an effect on student learning outcomes.

Abstract

This article aims to determine the effect of using the project-based learning model with the peer tutoring method in teaching Archimedes' principle in physics. This research was conducted at SMA Negeri 1 Tombatu using a quantitative research design with a one-group pre-test post-test design. The use of the project-based learning model with the peer tutoring method enabled students to understand the material taught, based on student learning outcomes, namely the pre-test results showed that the average score of students was 35.83 and increased to 84 in the post-test results. Thus, it can be concluded that the use of the project-based learning model with the peer tutoring method has a significant effect on student learning outcomes in physics learning on Archimedes' principle.

Abstract

The utilization of renewable energy has become a major focus in an effort to reduce dependence on fossil energy sources and reduce negative impacts on the environment, making it important to increase the use of clean and renewable energy. One of the biggest challenges in the application of renewable energy is efficient and sustainable energy storage. In this case, supercapacitors have proven to be a solution as an efficient and sustainable energy storage device. In this study, water hyacinth biomass material was tested as a supercapacitor electrode which was influenced by variations in Na2SO4 electrolyte, namely 1M, 2M, and 3 M, which produced voltages of 1.037 V, 1.404 V, and 1.647 V respectively and electric currents of 18.56 mA, 23.32 mA, and 32.34 mA. From the results of this study, it was found that the sample with an electrolyte concentration of Na2SO4 3 M had higher voltage and amperage values, which amounted to 1.654 V and 32.34 mA due to the greater number of Na+ and SO42- ions in the electrolyte. So it can be concluded that the variation of Na2SO4 electrolyte concentration of 1 M, 2 M, and 3 M results in an increase in the value of voltage and electric current produced by supercapacitors.

Abstract

Penelitian ini bertujuan untuk mengetahui peningkatan hasil belajar siswa dengan Model pembelajaran inkuiri terbimbing menggunakan pendekatan kontekstual dalam pembelajaran Energi mekanik. Penelitian ini menggunakan desain penelitian Pre-experimental Design dengan rancangan One-Group Pretest-Postest. Teknik sampling menggunakan non probability sampling. Sampel dalam penelitian ini adalah kelas X dengan jumlah 22 siswa sebagai kelas eksperimen. Data diperoleh dengan observasi, dokumentasi, dan tes. Analisis data yang digunakan diperoleh dari nilai pretest dan postest pada tes hasil belajar siswa. Selanjutnya dianalisis dengan uji normalitas dan hipotesis (uji-t). Perolehan nilai rata-rata untuk pretest 38,96 dan posttest 75,00. Dapat disimpulkan bahwa dengan menerapkan model pembelajaran inkuiri terbimbing menggunakan pendekatan kontekstual dapat meningkatkan hasil belajar siswa. Model Pembelajaran Inkuiri Terbimbing Menggunakan Pendekatan Kontekstual dapat diterapkan dalam pembelajaran fisika sebagai alternatif dikarenakan dapat meningkatkan hasil belajar siswa mnjadi lebih baik

Abstract

Tujuan penelitian ini adalah untuk mengetahui peningkatan hasil belajar siswa pada topik fluida statis dengan penerapan metode demonstrasi berbantuan media presentasi di SMA Negeri 1 Tombatu. Jenis penelitian ini adalah penelitian tindakan kelas (PTK) dengan Subjek siswa kelas XI IPA 1 SMA Negeri 1 Tombatu. Teknik pengambilan data adalah tes pada setiap siklus. Hasil yang diperoleh adalah terjadi peningkatan ketuntasan siswa siklus I sebesar 73,1% meningkat pada siklus II menjadi 96,15% dengan persentase penilaian kognitif, afektif dan psikomotorik pada masing-masing siklus yaitu siklus I 76,1%,77,1%,72,1% sedangkan pada siklus II meningkat menjadi 94,6%,87,2%,83,2%. Jadi dapat disimpulkan bahwa bahwa penerapan metode demonstrasi berbantuan media presentasi dapat meningkatkan hasil belajar siswa pada topik Fluida Statis di SMA Negeri 1 Tombatu.
