Analisis Kemampuan Representasi Matematis ditinjau dari Self Efficacy pada Siswa Kelas VIII MTs Negeri 2 Mataram Tahun Ajaran 2024/2025
No full textMathematical representation ability is an essential aspect of solving mathematical problems, particularly in the topic of relations and functions. However, in practice, many students struggle to express mathematical ideas through verbal, visual, and symbolic representations. One factor that may influence this ability is self efficacy, or students’ belief in their ability to complete mathematical tasks. This study aims to describe students’ mathematical representation ability in solving problems on relations and functions viewed from their self efficacy. The research was conducted at MTs Negeri 2 Mataram in the academic year 2024/2025 using a descriptive qualitative method. The subjects consisted of three eighth-grade students representing high, moderate, and low self efficacy categories based on questionnaire results. The instruments used included a self-efficacy questionnaire, a mathematical representation test, and interview guidelines. The findings show that students with high self-efficacy were able to fulfill all types of representation accurately and completely. Students with moderate self efficacy showed partial ability but were inconsistent. Meanwhile, students with low self-efficacy experienced difficulties in all forms of representation. These findings indicate a tendency that self efficacy plays a role in students’ quality of mathematical representation ability.Penelitian ini bertujuan untuk mendeskripsikan kemampuan representasi matematis dalam memecahkan masalah relasi dan fungsi yang ditinjau dari self efficacy siswa kelas VIII. Kemampuan representasi matematis mencakup kemampuan siswa dalam menyajikan ide atau konsep matematika melalui representasi visual, verbal, dan simbolik. Self efficacy merupakan keyakinan individu terhadap kemampuannya dalam menyelesaikan tugas-tugas tertentu, yang terdiri dari tiga indikator: level, strength, dan generality. Penelitian ini menggunakan pendekatan kualitatif deskriptif dengan subjek sebanyak 30 siswa kelas VIII MTs. Pemilihan subjek utama untuk dianalisis dilakukan berdasarkan hasil angket self efficacy, kemudian dipilih tiga siswa dengan kategori self efficacy tinggi, sedang, dan rendah. Instrumen penelitian berupa tes kemampuan representasi matematis, angket self efficacy dan pedoman wawancara semi terstruktur. Hasil penelitian menunjukkan bahwa siswa dengan self efficacy tinggi mampu menunjukkan kemampuan representasi yang lengkap dan tepat pada ketiga bentuk representasi, serta memiliki keyakinan kuat dalam menyelesaikan berbagai bentuk soal. Siswa dengan self efficacy sedang menunjukkan kemampuan yang cukup baik dalam representasi visual dan simbolik, namun masih lemah dalam penjelasan verbal. Sementara itu, siswa dengan self efficacy rendah menunjukkan keterbatasan dalam semua bentuk representasi serta memiliki keyakinan rendah terhadap kemampuannya sendiri. Dengan demikian, tingkat self efficacy berkorelasi dengan variasi dan kualitas representasi matematis siswa, meskipun tidak secara mutlak menentukan hasil akhir dari kemampuan tersebut

Evaluating Student-Built Earthquake Alarm Prototypes: Integrating Engineering Practices Through Real-World Projects in Junior High School
Full text linkPreparing students for 21st-century challenges requires learning experiences that connect scientific knowledge with real-world applications. This study investigates the integration of engineering practices in junior high school physics education through a project in which ninth-grade students designed and built simple earthquake alarm prototypes. The project adopted the PGBU (Pikir, Gambar, Buat, Uji)—a structured design process widely used in Indonesia—to guide students through iterative phases of thinking, sketching, building, and testing. Data from 24 student groups were analyzed using a rubric assessing functionality, application of physics concepts, creativity, construction neatness, and use of recycled materials. Most groups performed at moderate to high levels, with relatively higher performance observed in creativity and functionality. Results also indicated evidence of collaboration and the ability to apply physics concepts in real-world contexts. The project-based implementation of PGBU effectively fostered essential 21st-century competencies such as creative problem-solving, critical thinking, and teamwork. These findings highlight the potential of culturally grounded, design-based learning to support meaningful STEM education in junior high schools

The Study of Effectiveness of Chitosan from Pearl Oyster (Pinctada maxima) Shell as Antibacterial in Bone Scaffold Application
Full text linkChitosan is a functional material with potential for bone scaffolds due to its antibacterial properties, biocompatibility, biodegradability, low toxicity, and ability to support tissue regeneration and prevent infections in graft implantation.This study aims to identify changes in functional groups in each isolation process and identify the effect of chitosan concentration on the activity of Straphylococcus aureus and Escherichia coli bacteria. Chitosan isolation methods are demineralization, deproteination, decolorization, and deacetylation by microwave irradiation. Analysis of chitosan functional groups using FTIR, while antibacterial activity test using diffusion method. Isolation of chitosan from pearl oyster shells (Pinctada maxima sp.) obtained a degree of deacetylation of chitosan of 95.37%. Pearl oyster shell powder identified typical peaks of calcium carbonate (CaCO₃). The demineralized powder sample had calcium carbonate (CO₃²⁻) peaks that disappeared. Furthermore, the deproteinated powder sample produced peaks with amide groups (C=O dan N-H) of reduced protein. Decolorized powder samples did not show drastic changes in the bands of the deproteinated powder spectra, but the spectra could show cleaner and clearer peaks without any interference from pigments. The last, deacetylated powder sample showed a decrease in peak intensity in the 1650 cm⁻¹ (C=O amide). The analysis of the ability of chitosan to inhibit the growth of E. Coli and S. Aureus bacteria was effective at a minimum chitosan concentration of 20%. In comparison, antibacterial activity in S. aureus is better than in E. coli. Chitosan from this shell can serve as an antibacterial, but its manufacturing techniques need optimization for better efficacy
