Abstract

Antioxidant Activity Test Of Red Belt Leaf Extract (Piper crocatum) And Black Belt Leaf (Piper betle var nigra) Using The DPPH Method. Betel leaves (Piper betle L.) are among the most important agricultural products in the world, because the need for betel leaves as a raw material for traditional medicine has increased in the last decade. Betel leaves are known to contain phenolic compounds which have the potential to act as antioxidants. This study aims to determine the antioxidant activity of extracts of red betel leaves (piper crocatum) and black betel leaves (piper betle var nigra) using the dpph (1,1-diphenyl-2-picrihydrazyl) method. The research results showed that the antioxidant activity of the ethanol extract of red betel leaves, IC50, was 45,92 μg/mL, the ethanol extract of black betel leaves obtained an IC50 value of 87,09 μg/mL, and the vitamin C comparator obtained an IC50 value of 4,11. Red betel leaf extract has higher antioxidant activity than black betel leaf extract.Keywords: betel leaf (piper betle L.), antioxidant, dpph DOI:10.23960/jppk.v13i2.30534

Abstract

The project-based chemistry learning process can be carried out by studying phenomena in the surrounding environment so that students are interested and actively involved in solving problems given by the teacher related to chemical concepts. One of the alternative teaching materials that can be used as support is Student Worksheet. This study aims to determine the validity category of project-based learning-based green chemistry student worksheets for phase E at SMAN 9 Padang that have been developed. This type of research is Educational Design Research (EDR) using the Plomp development model. Plomp's development model consists of the stages of preliminary research, prototyping and assessment, but in this study it is limited to the prototype III stage. The validity instrument used was a questionnaire consisting of content and construct validity. The results of the validity in this study obtained an average V value of 0.85 with the valid category. Based on these results, it can be concluded that the student worksheets developed are valid. DOI: 10.23960/jppk.v12.i3.2023.12

Abstract

Pengembangan Lembar Kerja Elektronik Peserta Didik (E-Lkpd) Berbasis Literasi Sains Dalam Konteks Pewarnaan Kain Batik Pada Bahan Ikatan Kimia . Penelitian ini dilatarbelakangi oleh permasalahan pendidikan yang menjadi pertimbangan pemanfaatan teknologi digital dalam pembelajaran. Berbagai inovasi pemanfaatan teknologi dalam pendidikan dikembangkan oleh para pendidik sebagai sarana penting dalam tumbuh kembangnya kegiatan pengajaran. Pembelajaran kimia merupakan materi yang mempelajari konsep-konsep dasar yang bersifat abstrak. Guru sebagai fasilitator diharapkan mampu membantu siswa dalam memahami konsep kimia abstrak dengan mengaitkan materi kimia dengan kehidupan sehari-hari. Salah satu penerapan ilmu kimia dalam kehidupan sehari-hari adalah pewarnaan kain batik yang erat kaitannya dengan pembentukan ikatan kimia pada proses pembuatannya. Banyaknya permasalahan ilmu pengetahuan dan teknologi, literasi sains merupakan keterampilan yang sangat penting dan diperlukan dalam dunia pendidikan saat ini. Hasil wawancara dengan guru kimia SMA Swasta Nurul Iman Tanjung Morawa menyatakan bahwa guru belum pernah mengembangkan e-LKPD berbasis literasi sains dengan konteks pewarnaan kain batik. Penelitian ini bertujuan untuk mengukur hasil validasi ahli e-LKPD, mengkaji respon guru terhadap e-LKPD, dan mengkaji respon siswa terhadap e-LKPD. Jenis penelitian ini menggunakan metode Research and Development (R&D) yaitu model pengembangan 4D. Penelitian ini menggunakan sampel sebanyak 35 siswa dalam 1 kelas, 2 orang guru kimia, dan 4 validator ahli. Metode pengumpulan data yang digunakan adalah (1) wawancara, (2) angket respon guru dan respon siswa, dan (3) validasi ahli. Hasil penelitian menunjukkan bahwa pengembangan e-LKPD berbasis literasi sains konteks pewarnaan kain batik pada materi ikatan kimia layak digunakan dengan hasil validasi ahli materi sebesar 84,1% termasuk dalam kategori sangat layak, dan hasil validasi ahli media sebesar 87,75% termasuk dalam kategori sangat layak. Hasil angket respon guru sebesar 96,8% masuk dalam kategori sangat layak, dan hasil angket respon siswa sebesar 89% masuk dalam kategori sangat layak.Keywords: e-LKPD, Science Literacy, Batik Fabric Coloring, Chemical Bonding, Research and DevelopmentDoi : 10.23960/jppk.v13i2.29453

Abstract

The purpose of this study is to obtain interactive e-module products using conceptual change text strategies to reduce student misconceptions on the material colligative properties of solutions that are suitable for use. The colligative nature of solutions is a chemical material that is considered difficult because it is abstract and complex, causing students to find it difficult to understand the material. Learners who have difficulty in understanding the material's colligative properties of solutions can lead to misconceptions. To reduce misconceptions, an effort is needed, namely using a conceptual change text strategy packaged in the form of electronic learning media such as interactive e-modules. This study was prepared using research and development (R&D) research methods development model by Borg and Gall with descriptive analysis based on mode and shift misconceptions. Interactive e-module using conceptual change text strategy to reduce students' misconceptions on the material colligative properties of solutions are declared feasible based on content validity and construct, practicality and effectiveness. The validity of the content and construct obtained 4 or valid modes, practicality with a percentage of response questionnaire sheets of 95.8% or very practical and the percentage of observation sheets of student activities of 92.94% or very practical, and effectiveness in terms of the results of shifting misconceptions obtained by 87.36%. The results showed that the interactive e-module using the conceptual change text strategy to reduce students' misconceptions on the material colligative properties of the solution was declared feasible for useDOI: 10.23960/jppk.v12.i3.2023.03

Abstract

This implementation research is to determine the comparison of the improvement of learning outcomes and interest of students taught by using electronic module teaching materials based on Problem Based Learning and students taught by using high school chemistry textbook teaching materials and to determine the relationship between interest and the improvement of student learning outcomes in reaction rate material class XI at SMA Negeri 14 Medan. This research is a pure experimental research with pretest-posttest control group desaign design. Samples in the study were taken 2 classes using random sampling technique, namely class XI IPA 5 as an experimental class taught using PBL-based electronic module teaching materials and class XI IPA 2 as a control class taught using high school chemistry textbook teaching materials. The application of electronic module teaching materials is measured through the difference in the average n-Gain of student learning outcomes and interest, both in the experimental and control classes. The results showed that the increase in student learning outcomes and interest in the experimental class was higher than in the control class. The average increase in learning outcomes in the experimental class was 0.71 with an increase in interest of 0.54 and an increase in learning outcomes in the control class was 0.478 with an increase in interest of 0.31. Then, there is a correlation between interest and the improvement of student learning outcomes taught using PBL-based electronic module teaching materials of 0.764 with a high category.Keywords: PBL-based electronic modules, learning outcomes, learning interestDOI: 10.23960/jppk.v13.i1.2024.06
