Abstract

The use of virtual laboratories is a solution for schools that have not been able to carry out practical activities directly. This study aims to develop virtual laboratory electronic student using PjBL which can improve students' critical thinking ability. The research method used is the research and development (R & D) method with the ADDIE development model (analysis, design, development, implementation, & evaluate). The research subjects used were 30 students of class XII IPA who were selected using a purposive sampling technique. Data collection instruments consist of expert validation sheets, student response questionnaires, and critical thinking ability tests (pretest and posttest). The data analysis techniques used are Likert scale and n-gain analysis. The evaluation of the feasibility of electronic student worksheet by the expert got an average percentage of 85.41% with a very valid category, student test results got a n-gain value of 0.38 with a moderate improvement category, and the results of student responses got an average percentage value of 91.35% in the very good category. Thus, the developed virtual laboratory electronic student worksheet using PjBL can Improve students' critical thinking ability

Abstract

This study describes how phase composition affects the ability of giant magnetoresistance (GMR) chip-based sensors to detect magnetic labels made of Fe3O4 and Fe3O4/chitosan that were synthesized using the co-precipitation method. X-ray diffraction (XRD) analysis revealed that the synthesized nanoparticles were a mixture of magnetite and maghemite phases. The most intense diffraction peak at 2θ = 35.6° (311) confirmed the presence of the magnetite phase. The addition of chitosan significantly increased the proportion of the maghemite phase from 10% to 25%, with the appearance of an additional peak at 2θ = 33° (221). The modification of Fe3O4 nanoparticles into Fe3O4/chitosan nanocomposites resulted in changes in sensor sensitivity. The GMR sensor successfully detected Fe3O4 and Fe3O4/chitosan magnetic labels within 30 seconds with high sensitivities of 0.746 and 0.761 mV/( g/mL), respectively. The limit of detection (LOD) was also very low at 0.419 and 0.428 g/mL. These findings show that Fe3O4/chitosan nanocomposites integrated GMR chip-based sensors can be a dependable instrument for detecting a variety of biomolecules such as Bovine serum albumin (BSA).

Abstract

Pemahaman konsep merupakan salah satu kunci dalam keberhasilan siswa belajar fisika. Dengan pemahaman konsep yang baik maka siswa dapat memecahkan permasalahan dalam soal dengan baik pula. Penelitian ini bertujuan untuk menganalisis kesulitan siswa dalam memahami percepatan sentripetal dan gaya sentripetal menggunakan dua metode berebeda dan faktor penyebab kesulitannya. Dalam hal ini peneliti menggunakan platform video YouTube sebagai media dalam mengetahu kesulitan siswa dalam memahami materi. Penelitian ini menggunakan metode kualitatif dengan desain deskriptif kualitatif. Penelitian dilakukan kepada 30 siswa kelas 11 MIPA 2 SMAN 1 Panggarangan dengan memberikan tes tertulis berupa pilihan ganda beralasan dan wawancara terhadap 10 orang siswa yang dipilih berdasarkan kategori nilai. Sebelum dilakukan wawancara, siswa diminta untuk menonton video YouTube mengenai percepatan sentripetal dan gaya sentripetal. Hasil penelitian menunjukkan bahwa kedua video tersebut belum mampu membuat siswa menjadi paham konsep dari perceatan sentripetal dan gaya sentripetal, masih banyak konsep yang belum mereka pahami seperti besaran kecepatan linear dan keceatan sudut, arah dari percepatan sentripetal dan gaya sentripetal, penurunan rumus percepatan sentripetal dan gaya sentripetal, alasan mengapa percepatan sentripetal dan gaya sentripetal mengarah ke pusat dan mengapa arah kecepatan linear menyinggung lintasan. Dari hasil tersebut dapat disimpulkan bahwa pemahaman siswa terhadap konsep gaya sentripetal dan percepatan sentripetal masih rendah. Faktor internal yang mempengaruhi terjadinya kesulitan adalah belum memahami konsep, minat belajar fisika dan kondisi fisik. adapun faktor eksternal penyebab kesulitan belajar berdasarkan hasil penelitian adalah pembelajaran daring, manajemen waktu kurang baik dan lingkungan belajar.Kata kunci: Gaya sentripetal, percepatan sentripetal, kesulitan belajar, pemahaman konsep.

Abstract

Kurangnya minat siswa dalam pembelajaran fisika di sekolah akibat pembelajaran yang jarang menggunakan media pembelajaran dan cenderung monoton menjadi latar belakang dilakukannya penelitian ini. Tujuan penelitian ini adalah membuat media pembelajaran yang layak, melihat respon siswa terhadap media pembelajaran yang dibuat dan mengetahui pengaruh dari media yang dikembangkan terhadap minat belajar fisika siswa. Metode penelitian yang digunakan adalah Research and Development (RD) dengan model pengembangan 4D yang terdiri dari beberapa tahapan yaitu Define, Design, Develop dan Disseminate. Hasil penelitian menunjukkan bahwa produk media pembelajaran Fluidy memperoleh persentase sebesar 92% dalam kategori "sangat layak" berdasarkan validasi ahli materi dan media, lalu persentase sebesar 88% dalam kategori "sangat layak" berdasarkan hasil angket respons peserta didik. Selain itu, berdasarkan nilai standar gain sebesar 0,39 dengan kategori "sedang" membuktikan bahwa media pembelajaran Fluidy dapat meningkatkan minat siswa dalam pelajaran fisika. Dari hasil ini, dapat disimpulkan bahwa media pembelajaran Fluidy layak dan dapat digunakan untuk meningkatkan minat siswa dalam belajar fisika.

Abstract

Technological advances in the digital era have brought significant changes in the world of education, including in physics learning methods. This study aims to analyze the learning outcomes of students who use Artificial Intelligence (AI) and physics textbooks on harmonic vibration material. The study used a quantitative method with a quasi-experimental design of the control group pretest-posttest type. The study population was all students of class XI FA in one of the high schools in Serang Regency. The sample consisted of two classes selected purposively, namely XI FA 1 as the experimental class and XI FA 2 as the control class, each with 34 students. The instrument was in the form of 15 multiple-choice questions based on Bloom's Taxonomy (C1–C4) which had been tested for validity, reliability, difficulty level, and distinguishing power. The experimental class received AI-based learning, while the control class used a physics textbook. The results of statistical tests using SPSS 30.0 showed significant differences between the two classes with a significance value of 0.038 <0.05. The average posttest score of the experimental class was 82.72 (very high category), while the control class was 76.64 (high category). This shows that AI-based learning is more effective in helping to understand physics concepts, especially complex concepts such as harmonic vibrations. However, textbooks still have an important role in building conceptual understanding. Therefore, AI should be used as a complement, not a substitute for textbooks, to optimize student learning outcomes in physics learning. Abstrak. Kemajuan teknologi di era digital telah membawa perubahan signifikan dalam dunia pendidikan, termasuk dalam metode pembelajaran fisika. Penelitian ini bertujuan menganalisis perbandingan hasil belajar siswa yang menggunakan Artificial Intelligence (AI) dan buku teks fisika pada materi getaran harmonik. Penelitian menggunakan metode kuantitatif dengan desain quasi-eksperimental tipe control group pretest-posttest. Populasi penelitian adalah seluruh siswa kelas XI FA di salah satu SMA di Kabupaten Serang. Sampel terdiri dari dua kelas yang dipilih secara purposive, yaitu XI FA 1 sebagai kelas eksperimen dan XI FA 2 sebagai kelas kontrol, masing-masing 34 siswa. Instrumen berupa 15 soal pilihan ganda berdasarkan Taksonomi Bloom (C1–C4) yang telah diuji validitas, reliabilitas, tingkat kesukaran, dan daya pembeda. Kelas eksperimen mendapatkan pembelajaran berbasis AI, sedangkan kelas kontrol menggunakan buku teks fisika. Hasil uji statistik menggunakan SPSS 30.0 menunjukkan perbedaan signifikan antara kedua kelas dengan nilai signifikansi 0,038 < 0,05. Rata-rata nilai posttest kelas eksperimen adalah 82,72 (kategori sangat tinggi), sedangkan kelas kontrol 76,64 (kategori tinggi). Hal ini menunjukkan bahwa pembelajaran berbasis AI lebih efektif dalam membantu pemahaman konsep fisika, terutama konsep kompleks seperti getaran harmonik. Meskipun demikian, buku teks tetap memiliki peran penting dalam membangun pemahaman konseptual. Oleh karena itu, AI sebaiknya digunakan sebagai pelengkap, bukan pengganti buku teks, untuk mengoptimalkan hasil belajar siswa dalam pembelajaran fisika.
