Abstract

LKPD is a printed media or teaching material containing guide actors that can be used by students to develop their abilities.LKPD is one of the media to create a better learning atmosphere. LKPD was developed based on the PBL (ProblemBased Learning) model which is a learning approach to challenge students to think critically and acquire real-world problem-solving skills. This study was to analyze the completeness and contextual aspects of vector material PBL-based physics worksheets. This research uses the method of Research and Development (R&D).This development research is used to produce certain products and test the effectiveness of these products. The steps in the LKPD development stage include an assessment by development test experts, evaluation, and responses from experts and students. Based on the validation results obtained from the first validator and the second validator, it can be seen that the completeness and contextual aspects of PBL-based Physics Worksheets in vector material obtain an average value of 3 and 4 indicating that the results obtained are good. In addition, the contextual aspects of LKPD are able to improve high-level critical thinking skills in class X high school students because the material presented is related to everyday life. Overall, PBL-based physics worksheets on this vector material were deemed fit to be used as an effective physics learning medium.

Abstract

Terong gelatik (Solanum melongena L./merupakan salah satu sayuran yang paling digemari di Indonesia, karena memiliki rasa yang manis, tekstur yang renyah, dan kandungan gizi yang tinggi. Namun, produktivitasnya mengalami penurunan yang signifikan pada tahun 2022, yaitu sebesar 23,9%dibandingkan tahun sebelumnya, yang diduga disebabkan oleh menurunnya ketersediaan hara. Upaya potensial yang dapat dilakukan untuk mengatasi hal tersebut adalah peningkatan kesuburan tanah melalui aplikasi biochar tempurung kelapa dan biofertilizer. Tujuan penelitian ini adalah untuk mengkaji pengaruh aplikasi gabungan biochar tempurung kelapa dan biofertilizer terhadap konduktivitas listrik (EC) dan pertumbuhan terung gelatik, Metode penelitian yang digunakan adalah eksperimen, dengan 10 perlakuan. Hasil penelitian menunjukkan bahwa nilai EC mengalami penurunan setiap minggu pengamatan. Nilai EC tertinggi tercatat pada minggu ke-0 pada perlakuan P1 dengan nilai 1,81 mS/cm,yang menunjukkan ketersediaan hara optimal bag pertumbuhan tanaman. Namun, pada minggu ke-3dan ke-6, nilai EC mengalami penurunan yang signifikan pada semua perlakuan, yang menunjukkan adanya penurunan ketersediaan hara. Dalam hal pertumbuhan tanaman, nilai keseluruhan tertinggi tercatat pada perlakuan P7.
