Abstract

Teaching materials available in the field are still minimal and need to be developed. To enhance a more directed learning process, improve student learning outcomes, and increase student independence in learning, it is necessary to develop teaching materials for an independent curriculum. This research aims to develop a scientific-based static fluid practicum module of the independent curriculum. The type of research used is the Research and Development (R&D) using the ADDIE model through the stages of analysis, design, development, implementation, and evaluation. Data collection techniques were feasibility questionnaire, practicality questionnaire and multiple-choice questions for pre-test and post-test. The results of the analysis show that students lack direct observation in learning due to the unavailability of teaching materials that support practicum activities. This research data shows the percentage of the feasibility level of the practicum module which obtained an average of 92.2%, the practicality level of the practicum module obtained an average of 89.9% and the effectiveness level of the practicum module obtained an N-Gain of 0.70. The developed practicum module is feasible, practical, and effective in learning high school physics.

Abstract

This study aims to determine the problem-solving abilities of students with statis fluid material. The type of research used is RD with the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation). The research was conducted at SMA Swasta Persiapan 2 Padang Tualang in class XI, which amounted to 15 students for the small-scale test and 35 students for the large-scale test. The results of the study were obtained based on the results of validation by experts on three aspects of assessment, namely construct, material, and language, which obtained an average value of 95.8% with a very valid category. In the small-scale test, students’ problem-solving ability obtained an average score of 34.00 with a lower category, whereas in the large scale tets, students obtained an average of 59.00 with a lower category. So, it can be concluded that the test instrument developed can measure and improve students’ problem-solving skills.

Abstract

Urolithiasis is stone-like material that settles in the urinary tract. The materials that make up urinary stones are calcium oxalate, uric acid, cystine and stuvite. Several medical procedures are often applied to cure this disease. However, many patients choose traditional treatment by consuming herbal medicine. The aim of this research is to show the structure and morphology of uric acid with Orthosiphon Aristatus. This is very important to study as a basis for producing herbal medicines in nanometer sizes. Samples were prepared before characterization.  Urid Acid and Orthosiphon aristatus samples were weighed at a ratio of 0.1: 0.5 milligrams and dissolved in 100 milliliters of Aquabides. The samples were then characterized using XRD and SEM-EDX uric acid crystals mixed with Orthosiphon aristatus undergo progressive dissolution, characterized by an increasingly smooth surface and smaller particle size over time. The particle diameter of each sample changed from 37.64 to 32.83. This research will contribute to urinary stone sufferers choosing appropriate traditional medicine for the type of urinary stone they have

Abstract

This study aims to analyze the improvement of students’ conceptual understanding of energy and wave functions in a three-dimensional particle-in-a-box system through the use of a web-based Schrödinger 3D simulation. This research employed a quantitative approach with a one-group pretest–posttest design involving 20 physics students. The instrument used was a conceptual understanding test administered in the form of pretest and posttest. Data were analyzed using descriptive quantitative analysis and the Normalized Gain calculation. The results showed a significant improvement in students’ understanding. The average pretest score of 5.9 (39.3%) increased to 14 (93.3%) in the posttest. The N-Gain value of 0.89 was categorized as high, indicating that the web-based simulation is highly effective in enhancing students’ conceptual understanding. Based on questionnaire responses, the simulation was found to effectively visualize abstract concepts, increase learning engagement, and facilitate understanding of the relationship between energy, wave functions, and quantum numbers. However, several limitations were identified, particularly in the deeper understanding of wave functions and the need for further feature development. Therefore, the use of a web-based Schrödinger 3D simulation can serve as an effective alternative learning medium to improve students’ conceptual understanding in abstract quantum mechanics topics.

Abstract

This study aims to model the pursuit motion between guided missiles and a circularly moving aircraft using Python-based numerical simulation. The target moves along a circular path with a constant angular speed, while the missile follows a pure pursuit strategy, continuously adjusting its path toward the target's current position. Two scenarios are simulated: single pursuer and multi-agent pursuers. In the single-missile scenario, the missile forms a spiral trajectory and intercepts the target in approximately 4.9 seconds. In the multi-agent configuration, five missiles launched from different vertical positions successfully destroy the target within 8.3 seconds, with the first interception occurring at 6.7 seconds. The model is based on numerical solutions of differential equations governing relative motion dynamics. The results demonstrate that increasing the number of pursuers enhances interception speed and system effectiveness. The study is supported by animations, distance-time graphs, and damage analysis.

Abstract

Urgensi penelitian ini untuk meningkatkan kualitas pembelajaran fisika yang mampu mendorong siswa berpikir kritis dan analitis sesuai kebutuhan kompetensi abad ke-21. Penelitian ini diangkat oleh permasalahan banyaknya siswa yang mengalami kesulitan dalam menyelesaikan soal-soal yang menuntut penalaran, analisis hubungan antar konsep, serta penerapan konsep fisika dalam situasi baru. Salah satu penyebab utamanya adalah keterbatasan instrumen penilaian yang mampu mengukur kemampuan berpikir tingkat tinggi secara valid dan reliabel. Pengembangan instrumen Higher Order Thinking Skill pada materi fluida statis diharapkan dapat menjadi alternatif penilaian yang tidak hanya menilai hasil akhir, tetapi juga proses berpikir siswa dalam memecahkan masalah. Metode penelitian menggunakan model ADDIE (Analysis, Design, Development, Implementation, Evaluation). Subjek penelitian adalah 36 siswa kelas XI di SMA Negeri 18 Medan. Hasil validasi ahli memperoleh persentase kelayakan 100% (sangat layak), validitas butir soal memenuhi kriteria (r>0,329), reliabilitas tinggi (?=0,834), tingkat kesukaran soal berada pada kategori sedang, dan daya beda soal kategori baik. Respon siswa menunjukkan kategori cukup. Instrumen ini dapat digunakan untuk mengukur kemampuan berpikir tingkat tinggi siswa.

Abstract

This study aimed to develop and analyze a physics technological literacy test instrument on the topic of work and energy for senior high school students. This study addresses the limited availability of technological literacy assessment instruments specifically designed for the topic of work and energy in physics education. The research used a Research and Development (R&D) approach with the ADDIE development model, consisting of analysis, design, development, implementation, and evaluation stages. The instrument was developed based on three dimensions of technological literacy: knowledge, capabilities, and critical thinking and decision making. The study involved 200 students from several senior high schools in Binjai City, Indonesia. Data were analyzed using validity, reliability, and Rasch model analyses to evaluate the quality of the instrument. The results showed that the instrument was highly feasible, with evaluation expert validation of 92,13% and material expert validation of 90,4%. Practicality testing also indicated that the instrument was practical and easy to use. All items were categorized as valid and reliable, with a Cronbach’s Alpha coefficient of 0.935. The Rasch analysis demonstrated that the instrument could accurately measure students’ technological literacy abilities across various ability levels. The findings indicate that the developed instrument is valid, reliable, practical, and effective for measuring students’ technological literacy in physics learning, and it can serve as an assessment tool for teachers to evaluate and improve students’ technological literacy skills.
