Abstract

Hasil wawancara menunjukkan kemampuan berpikir kritis siswa masih rendah. Penyebabnya kemampuan siswa masih lemah dalam menganalisis saat proses pembelajaran. Tujuan penelitian ini melihat pengaruh penerapan model team assisted individualization dan self efficacy. Penelitian ini merupakan penelitian quasi eksperimen dengan rancangan faktorial design 2x2 yang menggunakan dua kelas yang dibandingkan. Kelas kontrol ataupun kelas eskperimen akan diberi pretest sebelum dilakukan proses pembelajaran dan posttest selesai dilakukan pembelajaran. Data penelitian diperoleh melalui angket self efficacy, tes kemampuan berpikir kritis dan lembar observasi. Analisis data menggunakan uji Anova dua jalur. Terbukti bahwa penerapan model Team assisted individualization memberikan pengaruh terhadap berpikir kritis siswa dibuktikan dengan nilai signifikan uji anova yang didapatkan <0,05 yaitu 0,00. Kemudian self efficacy juga memberikan pengaruh terhadap kemampuan berpikir kritis siswa, dibuktikan dengan nilai signifikan uji anova didapatkan <0,05 yaitu 0,00. Dan untuk interaksi antara model pembelajaran dengan self efficacy didapatkan nilai signifikan >0,05 yaitu 0,313 yang berarti tidak ada interaksi antara model pembelajaran dan self efficacy.

Abstract

The development of a metacognition-based e-book using 3D Pageflip on coordination polymerization reaction materials aims to enhance students' polymer chemistry literacy. The Polymer course in the Chemistry Education Study Program covers various polymerization reactions essential for students in today's educational era. Polymers, including plastics, Styrofoam, nylon, and others, are crucial materials in various aspects of life. Due to the abstract nature of this subject, theoretical explanations are challenging for students to understand. A metacognition-based e-book is expected to assist students in self-learning, increasing flexibility in understanding polymerization reaction materials. This study employs the ADDIE development model (Analysis, Design, Development, Implementation, and Evaluation) and produces an e-book containing text, animations, videos, and music. Validation by experts indicates that the e-book is excellent in terms of content and design. Implementation among students shows that this e-book is effective in enhancing the understanding of coordination polymerization reactions. Thus, the e-book is expected to facilitate learning and improve students' polymer chemistry literacy. Keyword:        Science literacy, polymer chemistry, polymerization reaction, coordination polymerization.

Abstract

Premna serratifolia Linn leaf possesses medicinal properties, useful in the treatment of cardiovascular diseases, skin diseases, inflammatory diseases, arthritis, rheumatism, anorexia, jaundice, intestinal worms, bad breath, lung infections, febrifuge, hypolipidemic, antioxidants, antidiabetic, CNS depressant and thalasemia treatment, among other things. The purpose of this study was to investigate the antioxidant effect of P. serratifolia Linn leaf from Indonesia. The leaves of P. serratifolia Linn were extracted with 95% ethanol and fractionated with n-hexane and ethyl acetate. The antioxidant activity was evaluated by various antioxidant assays, including  1-diphenyl-2-picrylhydrazyl (DPPH), 2’-azino-bis(3-ethylbenzthiazoline-6-sulfonic acid) (ABTS), nitric oxide scavenging and reducing power ability method. The extracts and fractions contained phytoconstituents such as alkaloid, flavonoid, phenolic, tanin, saponin, and steroid compounds, according to phytochemical analysis. The antioxidant activities were compared to standard antioxidant ascorbic acid. P. serratifolia Linn ethanol leaves extract showed a significant antioxidant activity in DPPH, ABTS, reducing power and nitric oxide scavenging methods compared others. The findings of the present study suggest that P. serratifolia Linn could be a potential source of natural antioxidant that could have greater importance as therapeutic agent in preventing or slowing oxidative stress related degenerative diseases.

Abstract

Physical Chemistry II course in the Chemistry Education Study Program is one of the subjects with an abstract nature, such as Electrochemistry materials. The abstract nature of Electrochemistry makes it difficult for students to observe the processes occurring in Electrochemical systems directly. When explained theoretically, these concepts are often challenging for students to understand. Therefore, teaching Electrochemistry requires an e-book that incorporates chemical representations, particularly multiple representations. To address this, it is deemed necessary to develop an Electrochemistry e-book based on multiple representations using 3D PageFlip. This e-book integrates multiple representations, enabling students to independently study and comprehend Electrochemistry materials while providing flexibility and convenience. An Electrochemistry e-book with multiple representations, particularly in a computer-assisted learning format, is a viable alternative to support student learning. This study aims to develop an Electrochemistry e-book using 3D PageFlip based on multiple representations. This software allows the creation of interactive and engaging educational resources. The resulting e-book aims to enhance students' individual abilities and increase their interest and motivation, which in turn is expected to improve their academic performance and learning outcomes. Moreover, this multimedia learning tool is intended to address challenges related to students' limited comprehension during classroom learning processes, accommodate individual characteristics, and offer alternative solutions to the low self-actualization of students. Through this e-book, students can revisit and explore difficult concepts, facilitating deeper understanding. The ultimate goal of this research is to produce an Electrochemistry e-book based on multiple representations across macroscopic, microscopic, and symbolic levels using 3D PageFlip. This e-book will align with the applicable curriculum and adhere to educational principles while incorporating essential educational elements. By improving concept mastery in Electrochemistry, this resource is expected to enhance students' cognitive abilities and overall learning outcomes
