Abstract

Media pembelajaran interaktif merupakan media yang memfasilitasi interaksi aktif antara siswa dan materi yang mendapatkan umpan balik langsung, memungkinkan untuk meningkatkan pemahaman siswa terhadap materi sistem koloid. Penelitian ini bertujuan untuk mengetahui cara pengembangan, cara penggunaan, dan respon siswa terhadap media pembelajaran interaktif yang dikembangkan. Proses pengembangan produk dalam penelitian ini mengikuti tahapan dalam model pengembangan Lee and Owens. Instrumen penelitian berupa lembar wawancara, angket analisis kebutuhan siswa, angket validasi ahli dan respon siswa. Teknik analisis data secara kualitatif yang berupa saran dan komentar terhadap media dan kuantitatif berupa skor penilaian. Hasil penelitian menunjukkan bahwa media pembelajaran interaktif berbasis Game Based Learning menggunakan Kahoot dinyatakan layak berdasarkan penilaian ahli, guru, dan respon siswa yang sangat positif dengan persentase kelayakan 93,72%. Berdasarkan hasil penelitian dapat disimpulkan bahwa media pembelajaran interaktif berbasis Game Based Learning menggunakan Kahoot pada materi sistem koloid yang dikembangkan valid dan layak digunakan pada proses pembelajaran dengan respon baik dari siswa.

Abstract

This study aims to isolate and characterize limonoid compounds from Clausena excavata Burm.F and evaluate their antibacterial potential against Enterococcus faecalis, a pathogen associated with antibiotic resistance in healthcare settings. Plant samples were collected from natural habitats in Southeast Asia and identified by botanists for authenticity. The leaves, stems, and fruits were dried, ground into fine powder, and subjected to ethanol/methanol maceration, followed by liquid-liquid fractionation. Column chromatography and Thin Layer Chromatography (TLC) were used for initial compound separation, while High-Performance Liquid Chromatography (HPLC) was employed for further purification. Structural characterization was conducted using Nuclear Magnetic Resonance (NMR), Mass Spectrometry (MS), and Fourier Transform Infrared Spectroscopy (FTIR). The antibacterial activity of the isolated limonoids was tested against E. faecalis using the disk diffusion method, with Minimum Inhibitory Concentration (MIC) and Minimum Bactericidal Concentration (MBC) determined through broth microdilution assays. The results indicate that limonoid compounds from Clausena excavata exhibit moderate antibacterial activity, producing inhibition zones smaller than standard antibiotics but still demonstrating potential for bacterial growth suppression. This study highlights Clausena excavata as a promising natural source of antibacterial agents, contributing to alternative solutions against antibiotic-resistant bacteria. The findings support further exploration of limonoids as lead compounds for novel antimicrobial drugs, promoting the use of natural products in combating antibiotic resistance and advancing phytopharmaceutical applications in healthcare.

Abstract

Purpose of the study: This research aims to describe the response of science subject teachers to the assessment of students' process skills portfolios. Methodology: The research method used in this research is mixed, namely a combination of qualitative and quantitative methods. The research design chosen was a sequential explanatory design. This design was selected because quantitative research was carried out first and followed by qualitative methods. This design ensures that the quantitative data obtained is strengthened with qualitative data. Quantitative data analysis techniques are carried out using descriptive statistics. Meanwhile, qualitative data was analyzed based on Miles and Huberman's theory. The instrument used to collect quantitative data is a questionnaire sheet to measure teacher responses in portfolio assessment. Meanwhile, qualitative data was obtained from interviews and documentation studies on relevant problems. The population of this research is schools in Jambi Luar Kota District. The research sample is science subject teachers. The sampling technique used was cluster random sampling. Main Findings: The results obtained are the teacher's response in State Junior High School 1 Muaro Jambi superior to State Junior High School 1 Atap Pematang Jering. Novelty/Originality of this study: The urgency of this research is seen from the importance of assessment in learning activities, which is a tool for measuring student abilities and evaluating the education system. The background of this research is limited by the sample involved being only science subject teachers, and the population chosen is the Jambi Luar Kota sub-district.

Abstract

Purpose of the study: This study aims to evaluate teachers' responses to two learning models, namely problem-based learning and scaffolding, in the context of science subjects at Junior High School Negeri Satu Atap Pematang Jering. Methodology: The methodology used was descriptive quantitative research with a population of teachers in the school. The research sample consisted of 16 teachers selected by purposive sampling. Data were analyzed using descriptive statistics. Main Findings: The main finding of this study shows that most teachers (75%) in Junior High School Negeri Satu Atap Pematang Jering responded positively to the use of problem-based learning and scaffolding models in science learning. These results indicate that both learning models effectively improve the quality of teaching and students' understanding of science materials. Novelty/Originality of this study: The novelty of this research lies in its specific focus on analyzing teachers' responses to problem-based learning and scaffolding models. This research contributes to the existing literature in this field by providing a deeper understanding of how these two learning models can be applied in science learning in secondary schools. The results of this study can serve as a guideline for teachers and schools in selecting and implementing effective learning strategies to improve teacher competence and student learning outcomes in science subjects.
