Abstract

Students’ thinking schemes must be revealed to discover the students’ fundamental problems in solving direct current (DC) electrical circuit problems. Concept maps and problem-solving can be used to reveal students’ thinking schemes. The method used in this study is descriptive qualitative. The research was conducted on second-semester students who took the Fundamental Physics II course at a private university in Madiun in 2023/2024, totaling 9 students. Data was collected using the documentation method in the form of assignments to make concept maps, tests, and interviews. The results of this study reveal students’ thinking schemes, which can be categorized into computational thinking (CT), non-CT, and combined thinking (CT and non-CT). Non-CT students’ thinking schemes use trial and error methods to solve problems and intuition to conclude.

Abstract

A performance feature is a domain-specific to the organization of knowledge. Well-organized knowledge is characterized when students are able to collaborate the knowledge features of the physics problem.  The knowledge feature can be a cognitive activity where teachers influence students by changing the pattern of knowledge from "defining" to "applying" knowledge. This research aims to analyze whethet the cognitive activity from the teacher can generate student’s argumentation performance features or no. This study is a qualitative descriptive study which involved 100 of high school students in Bandar Lampung.   The data  was collected using a research instrument in the form of reasoned multiple choices which has been validated.  The results of this study showed that students' involvement in cognitive activity by following variety of procedures can generate student’s argumentation performance fetaures.

Abstract

This paper studies the thermodynamic and magnetic properties of some diatomic molecules governed by Scarf and Morse non-central potentials under external magnetic and electric fields. The Schrodinger equation with Scarf and Morse non-central potentials is solved using Supersymmetric WKB quantization conditions to obtain the energy equation and wave function. The influence of the magnetic and electric fields on the energy eigenvalue was discussed. The results show that energy increases with the increasing magnetic field and decreases with the increasing electric field. Moreover, the thermodynamic and magnetic properties involving internal energy, free energy, specific heat capacity, entropy, magnetization, magnetic susceptibility, and persistent current were determined by calculating the partition function. The internal energy increases linearly with the increasing magnetic field for a given temperature. Meanwhile, the specific heat capacity decreases with the increasing magnetic field. We point out that the presence of magnetic and electric fields makes the system exhibit diamagnetic behavior.

Abstract

This research aims to review the characteristic of the nature of electricity polymer material poly(3-hexylthiophene) P3HT against increasing efficiency solar cells based on dye-sensitized solar cells (DSSC). The testing sample has done electricity P3HT el-kahfi 100/ I-V meter. The optical properties use spectrophotometer UV visible 1601 PC and characterizing IV DSSC use Keithley 2600 a type. The absorbance of P3HT polymer 1% has an absorption peak in the wavelength range of 300-650 nm. Thus the P3HT polymer material can absorb light in the visible wavelength range. The electrical properties of P3HT 1% indicate that the material has a response to light. In bright conditions, P3HT 1% shows a conductivity of 3.7x10-3Ω-1m-1 and in dark conditions 2.2x10-3Ω-1m-1. Meanwhile, Pt (Hexacloroplatinic IV) Platina as the opposing electrode can improve the performance of DSSC, which is because Pt (Hexacloroplatinic IV) functions as a catalyst to accelerate the redox reaction with electrolytes. The use of P3HT 1% can improve DSSC performance. DSSC using 1% P3HT and using Pt (Hexacloroplatinic IV) as the opposing electrode produced an efficiency value of 1.8x10-2%.

Abstract

Siswa kelas XI memiliki kesulitan dalam mempelajarimateri teori kinetik gas karena sifatnyacukup abstrak. Agar siswa lebih mudah dalam memahami teori kinetik gas, diperlukan bahan ajar yang tepat dan sesuai dengan perkembangan berpikir siswa serta sejalan dengan penerapan kurikulum 2013. Salah satu bahan ajar yang dikembangkan sebagai solusi yaitu modul. Penelitian ini bertujuan untuk (1) mengembangkan modul fisika berbasis saintifik pada materi teori kinetik gas, (2) mengetahui kelayakan modul fisika berbasis saintifik, dan (3) mengetahui respon siswa terhadap modul fisika berbasis saintifik. Penelitian ini merupakan penelitian pengembangan yang mengadaptasi dari perangkat pengembangan model 4-D. Tahap pengembangan dibatasi hingga Develop. Penelitian ini dilakukan di MAN Yogyakarta I. Instrumen pengumpulan data antara lain lembar observasi;lembar pedoman wawancara guru dan siswa; angket pengungkap kebutuhan guru dan siswa; lembar validasi untuk ahli materi, ahli media, ahli bahasa, guru fisika, dan peer reviewer; dan angket respon siswa untuk uji terbatas serta uji luas. Teknik analisis data yang digunakan yaitu analisis kuantitatif deskriptif. Berdasarkan validasi yang dilakukan oleh ahli materi, ahli media, dan ahli bahasa, modul fisika memiliki kualitas sangat baik dengan persentase berturut-turut 80,77%, 91,18%, dan 85,00%. Validasi oleh seorang guru fisika dan dua orangpeer reviewer menunjukkan bahwa modul fisika berkualitas sangat baik dengan persentase berturut-turut 89,00%, 86,11%, dan 92,59%. Kelayakan modul fisika dihitung berdasarkan nilai persentase rata-rata yang lebih besar daricut off score. Persentase rata-rata seluruh validator sebesar 87,44%, sementara cut off score sebesar 86,68%, sehingga modul fisika ini layak untuk dikembangkan.Respon siswa menunjukkan bahwa modul fisika dikategorikanbaik pada uji terbatas dan sangat baik pada uji luas. Kesimpulan dari penelitian ini yaitu (1) pengembangan modul fisika pada materi teori kinetik gas adalah modul yang dikembangkan berdasarkan komponenpembelajaran berbasis saintifik, (2) modul dikategorikan layak, dan (3) respon siswa pada modul dikategorikan baik dan sangat baik.
