Abstract

This study aimed to develop a Problem-Based Learning Electronic Student Worksheet to improve learning outcomes in acid-base material for Grade XI students. The research employed a developmental design using the Plomp model, encompassing preliminary investigation, design and prototype development, and assessment phases. Data collection involved expert validation, teacher and student evaluations, and pre-test/post-test assessments with Grade XI students from a public senior high school selected through purposive sampling. The results demonstrated high validity with Aiken's V values of 0.86 for content validity, 0.83 for media validity, and 0.86 for learning validity. Practicality assessment revealed high acceptance with teacher ratings of 4.38 on a five-point scale and 90.46% student acceptance rate. Effectiveness testing showed significant improvement in learning outcomes, with mean scores increasing from 71.61 to 89.44. Statistical analysis using paired sample t-test indicated significant differences with Cohen's d effect size of 2.26, demonstrating substantial educational impact. The study concluded that the Problem-Based Learning Electronic Student Worksheet is valid, practical, and effective for enhancing student learning outcomes in acid-base chemistry, providing a valuable digital learning resource for twenty-first century chemistry education

Abstract

This study aims to develop a valid and practical learning system in addressing the need for an instructional design that fosters digital literacy in first-year chemistry students. Using the Educational Design Research framework, the learning system was developed on Discord and integrated flipped-guided inquiry learning models. The study involved lecturers and students from Department of Chemistry, Universitas Negeri Padang. The system was structured with a server and channels to facilitate each stage of the learning process. The evaluation assessed the validity and practicality of the system. The overall results indicated the system was highly valid with overall validity of 0.85 (construct validity 0.85 and content validity 0.86) and practical (student practicality 81% and lecturer practicality 83%). These findings suggest that a Discord-based, flipped-guided inquiry system is a highly viable and useful tool for teaching thermochemistry and student’s digital literacy.

Abstract

To response the needs for 21st century competencies among chemistry students, a novel approach on learning in higher education is paramount. This study presents the development and evaluation of a flipped classroom learning system for chemical kinetics, designed to enhance digital literacy and guided inquiry through Discord. This research followed the Educational Design Research (EDR) model outlined by Plomp and Nieveen and limited to development studies; yielding  a refined learning system prototype. The developed learning system was validated by five lecturers from Universitas Negeri Padang, resulted in content (0.85), and construct validity (0.82). Meanwhile, the practicality of the learning system was also evaluated by students and lecturers, resulted in practicality indexes of 88% and 85%, respectively. All of the results suggest high level of validity and practicality meaning the learning system has achieved the quality criteria content, structure, and usage wise. These results imply for the utilization platforms like Discord for higher education learning to promote student-centered learning and digital literacy.

Abstract

This research aims to design a flipped classroom learning system incorporating guided inquiry, using the Discord platform for buffer solution materials in Phase F. The study employed Plomp Educational Design Research framework, which comprises initial investigation, design, construction, testing, evaluation, and refinement. The product underwent validation through expert evaluation and was assessed for practicality and effectiveness. The content validity achieved a score of 0.89, while the media validity scored 0.90, meaning both belong to the valid category. Evaluation of practicality showed that the system was highly practical, with teachers and students giving it an overall score of 90% and 92% respectively. Effectiveness was measured by analyzing pretest and posttest results using the N-Gain formula, yielding a score of 0.75, which is classified as high gain. The overall findings suggest that the developed learning system is valid, practical, and effective in enhancing students’ understanding of buffer solutions. Moreover, the integration of Discord provides an accessible and interactive digital environment, aligning with the needs of 21st-century education and the Merdeka Curriculum. Therefore, this model can be recommended as an innovative solution for digital chemistry instruction in senior high schools.

Abstract

Air sumur merupakan sumber air utama yang digunakan masyarakat indonesia untuk kebutuhan sehari-hari. Salah satu upaya yang dapat dilakukan untuk menjaga kualitas air sumur dengan mengidentifikasi keberadaan logam berat terutama timbal (Pb). Timbal (Pb) adalah logam berat dengan sifat toksisitas yang tinggi. Paparan timbal dalam jumlah yang tinggi dapat mengakibatkan berbagai masalah kesehatan kronis, dimulai dari kulit pucat, penurunan tekanan darah, diare hingga kerusakan hati dan ginjal bahkan menyebabkan karsinogenik. Tujuan penelitian ini untuk menganalisa kadar Pb pada air sumur warga di kecamatan Tenayan Raya Pekanbaru melalui analisis menggunakan Spektrofotometri Serapan Atom (SSA). Spektrofotometri Serapan Atom dipilih untuk menganalisis kadar timbal (Pb) dalam penelitian ini karena mempunyai sensitivitas serta akurasi yang memadai untuk dilakukannya analisis logam terlarut di dalam sampel air. Penelitian yang telah dilakukan di peroleh kadar Pb pada sampel air sumur sebesar 0,086 mg/L. Kadar air ini berada diatas batas maksimum yang diizinkan untuk air minum (0,01 mg/L) dan air untuk keperluan hygiene sanitasi (0,05 mg/L) berdasarkan Peraturan Menteri Kesehatan Republik Indonesia Nomor 492/MENKES/PER/IV/2010 dan Peraturan Menteri Kesehatan No 32 Tahun 2017. Sehingga diperlukan upaya lebih lanjut untuk mengontrol dan memperbaiki kualitas air agar memenuhi standar kesehatan yang ditetapkan.

Abstract

Inflamasi merupakan respon biologis tubuh terhadap rangsangan berbahaya, namun inflamasi berlebihan dapat menimbulkan kerusakan jaringan dan penyakit degeneratif. Enzim Cyclooxygenase-2 (COX-2) berperan penting dalam proses inflamasi, sehingga menjadi target utama dalam pengembangan obat antiinflamasi yang lebih aman dibandingkan NSAID konvensional. Tujuan penelitian ini untuk mengetahui potensi senyawa bioaktif daun kacang gude (Cajanus cajan) sebagai kandidat agen antiinflamasi melalui penghambatan enzim COX-2. Penelitian dilakukan secara in silico menggunakan perangkat lunak MOE dengan metode molecular docking terhadap sepuluh senyawa bioaktif daun kacang gude terhadap reseptor COX-2 (kode PDB: 1CX2). Evaluasi meliputi nilai energi ikatan, RMSD, serta kesesuaian Lipinski’s Rule of Five dan profil ADMET. Dua senyawa terbaik yang memiliki afinitas kuat terhadap COX-2 adalah ?-selinene dan ?-tocopherol dengan energi ikatan masing-masing 1,2433 kcal/mol dan 1,4352 kcal/mol serta RMSD -6,4444 Å dan -8,1138 Å. Keduanya memenuhi kriteria drug-likeness. Senyawa ?-selinene dan ?-tocopherol berpotensi sebagai kandidat obat antiinflamasi alami melalui penghambatan COX-2. Diperlukan validasi lanjutan melalui uji in vitro dan in vivo untuk memastikan efektivitas serta keamanannya.
