Abstract

This study developed innovative approaches to chemistry education for first-year students at the State University of Padang in the era of Industry 4.0. The research utilized the Plomp development model to formulate a method based on the Flipped Classroom paradigm with a Guided Inquiry Syntax. The resulting content was validated by five Chemistry lecturers at UNP, indicating its innovative and pertinent material depth. The content's practicality achieved a value of 90%, suggesting its ease of application and relevance for students. The systematic presentation enhances students' understanding of the Periodic System. This research offers valid and practical solutions to challenges in chemistry education, using creative content as an innovative strategy to provide a teaching tool that enhances students' understanding of complex concepts. The study's practicality stage demonstrates that the developed content is easy to apply and relevant for students, making it a valuable addition to chemistry education

Abstract

Komposit bermatrixs polimer berserat alam semakin luas dikembangkan sebagai alternatif ramah lingkungan dan berpotensi digunakan dalam berbagai aplikasi teknik,termasuk komponen otomotif. Penelitian ini bertujuan untuk menganalisis pengaruh variasi komposisi hibrid serat daun nanas (Pineapple Leaf Fiber) dan serat ijuk (Arenga Pinnata) terhadap kekuatan impak dan daya serap air pada komposit bermatriks epoxy. Penelitian ini merupakan peneltian eksperimen dengan fraksi volume total serat 30% dan matriks epoxy 70% yang dicetak dengan metode hand lay-up. Variasi perbandingan serat daun nanas dan serat ijuk yang digunakan meliputi sampel A (20% :10%), sampel B (15% : 15%), dan sapel C (10% :20%). Sebelum pencetakan serat diberikan perlakuan kimia menggunakan NaOH 5% selama 2 jam. Spesimen impak dibuat sesui standar ASTM D6942-96 di uji mengunakan Charpy, sedangkan uji daya serap air mengikuti standar ASTM D570 dengan durasi perendaman 24 jam. Hasil penelitian ini menunjukan nilai kekuatan impak tertinggi dicapai pada variasi C ( 10% serat nanas : 20% serat ijuk) sebesar 0,3077 J/mm², sedangkan persentase daya serap air terendah diperoleh pada variasi A ( 20% serat nanas : 10% serat ijuk) sebesar 0,68%. Berdasarkan keseimbangan performa mekanik dan fisis, variasi A mengahsilkan nilai yang paling optimal karena memiliki kekuatan impak tinggi serta ketahanan penyerapan air yang paling rendah.
