Abstract

This study aims to identify students' initial abilities in biopolymer materials as a basis for developing learning designs. This study uses a content analysis method, with participants being fourth-semester students in one of the Chemistry Education study programs, at a state university in West Java. The instrument used in this study was a descriptive test consisting of 13 questions. The results of the Initial ability data analysis showed that overall, it was identified that 41% of students had an Initial ability understanding with a sufficient category, 33% of students had a poor category, 23% of students had a good category and 3% of students had an initial ability understanding with an outstanding category. Based on these findings, several interventions are suitable as references in developing didactic designs, such as displaying learning videos related to the manufacture of simple bioplastics, graphs of development and annual production costs of bioplastics, images of bioplastic applications in various fields, and infographics related to the decomposition process and the benefits of sustainability of bioplastics.

Abstract

Chemistry learning requires innovative strategies to enhance students' understanding, particularly in thermochemistry, which is often considered challenging. This study aims to evaluate the effectiveness of implementing a Higher Order Thinking Skills (HOTS) and Science, Technology, Engineering, and Mathematics (STEM)-based chemistry module in improving students' learning outcomes. A quasi-experimental method with a pretest-posttest design was employed in this research. The subjects were students learning thermochemistry using the Higher Order Thinking Skills (HOTS) and Science, Technology, Engineering, and Mathematics (STEM)-based chemistry module. Data were collected through pretest and posttest assessments and analyzed using n-gain calculations to measure learning improvement. The results showed that the average n-gain obtained was 0.372, classified as a moderate category. These findings indicate that the chemistry module effectively enhances students' understanding, although the improvement is not yet optimal. Several factors, such as limited instructional time and students' readiness in comprehending the module, may have influenced the results. Therefore, further development is needed to optimize the module's effectiveness, such as integrating discussion-based and hands-on experimental learning methods.

Abstract

Kurangnya fasilitas laboratorium yang memadai dan panduan praktikum berkualitas rendah di banyak sekolah menengah atas menghambat pembelajaran praktikum kimia yang efektif. Untuk mengatasi hal ini, penelitian ini mengembangkan dan mengevaluasi panduan praktikum kimia berbasis penyelidikan terbimbing yang terintegrasi dengan prinsip-prinsip kimia hijau, menggunakan model ADDIE (berfokus pada tahap pengembangan). Validasi dilakukan oleh enam guru kimia dan dua dosen, menilai aspek-aspek seperti konten, bahasa, penyajian, dan desain. Metode kuantitatif deskriptif dalam kerangka RD digunakan untuk analisis. Panduan tersebut menerima skor rata-rata keseluruhan sebesar 4,78 dari 5, yang menunjukkan bahwa panduan tersebut "sangat layak." Secara khusus, skor untuk konten, bahasa, penyajian, dan desain masing-masing adalah 4,78, 4,82, 4,78, dan 4,75. Hasil-hasil ini menunjukkan bahwa panduan tersebut sesuai untuk meningkatkan pembelajaran kimia praktis dan menumbuhkan kesadaran lingkungan melalui kimia hijau di sekolah menengah atas.

Abstract

This research examines the effect of the discovery learning model on higher-order thinking skills in chemistry subjects at the high school level in Indonesia with a total sample of 230 students. The research method is a meta-analysis study with a range of research data from 2015-2024 based on Google Scholar indexed by Sinta. Heterogeneity test analysis using JASP version 0.8.5 shows a τ² value of 0.236 and a τ value of 0.485, with an I² value approaching 100% (CI: 74.015%–98.358%). The results indicate a high level of heterogeneity (98.358%). Therefore, a random effects model is used in the analysis. The meta-analysis results suggest that discovery learning significantly affects higher-order thinking skills (z = 4.730; p < 0.001; 95% CI). Funnel plot and Egger's tests did not show publication bias, supported by a fail-safe N value 488. The results of this study reinforce empirical evidence that discovery learning is a practical approach to chemistry learning.

Abstract

Peningkatan kualitas pakan ternak ruminansia menjadi salah satu faktor penting dalam mendukung produktivitas susu kambing perah, yang secara tidak langsung berkontribusi dalam dunia kesehatan sebagai upaya pencegahan stunting melalui pemenuhan gizi keluarga. Namun, mitra peternak di Desa Pasar Baru, Kecamatan Teluk Mengkudu, Kabupaten Serdang Bedagai masih menghadapi kendala dalam proses pencampuran pakan secara manual yang memakan waktu lama dan menghasilkan pakan yang tidak homogen. Kegiatan pengabdian ini bertujuan untuk memberikan solusi melalui penerapan teknologi tepat guna berupa mesin pencampur pakan serta pelatihan manajemen usaha. Metode yang digunakan meliputi pendidikan, pelatihan, dan praktik langsung. Hasil kegiatan menunjukkan bahwa mitra mengalami peningkatan efisiensi kerja, dengan waktu pencampuran pakan yang berkurang signifikan, serta peningkatan homogenitas pakan yang berdampak positif terhadap kualitas dan kuantitas susu kambing. Selain itu, pelatihan pengemasan dan pemasaran turut mendukung penguatan aspek kewirausahaan mitra. Kegiatan ini memberikan dampak nyata dan berkelanjutan dalam peningkatan produktivitas ternak serta ekonomi rumah tangga peternak.
