Abstract: Development of An Interactive Problem-Based Learning E-Module to Improve Higher-Level Thinking Abilities in Thermochemistry. 21st-century education demands the development of students' Higher Order Thinking Skills (HOTS). However, the abstract and calculation-heavy nature of the eleventh-grade thermochemistry material makes it difficult for students to comprehend when relying solely on conventional textbooks. Furthermore, the learning process in schools is still heavily dominated by teacher-centered lecture methods. As a solution, an interactive e-module was developed by integrating multimedia and the Problem-Based Learning (PBL) model to stimulate analytical thinking and problem-solving skills. This study is a Research and Development (R&D) project using the 4D development model, which consists of the Define, Design, Develop, and Disseminate stages. The instrument trial subjects involved 35 eleventh-grade students in class XI C at SMA Negeri 17 Medan. The feasibility of the e-module was evaluated through validation by material and media expert lecturers. The validation results showed an average score of 93.93% from the material experts and 92.15% from the media experts, classifying the e-module as highly valid. Additionally, the e-module received a highly positive response from students, achieving a practicality percentage of 88.17%. The use of the interactive PBL-based e-module is proven effective in improving students' Higher Order Thinking Skills. This is demonstrated by the increase in the average score from the pretest (28.19) to the posttest (82.09), yielding an N-Gain score of 0.74, which falls into the medium category.

Abstract

Abstract: Sansevieria Trivasciata (snake tongue) is a traditional medicinal plant known to contain various bioactive compounds. This study aims to identify secondary metabolite content and characterize Sansevieria leaf crude extract. Plant samples were obtained from Aekbolon village, North Sumatra, and have undergone a taxonomic identification process. The crude extract was prepared by drying and grinding the leaves. The characterization results showed a water content of 8.5% and a water-soluble extract content of 23.85%, which is in accordance with the quality standards of crude extracts according to the Indonesian Herbal Pharmacopoeia. Extraction was carried out using a maceration method using 96% ethanol for three consecutive days. The resulting thick extract was then tested qualitatively to detect secondary metabolites. The screening results showed the presence of allkaloids, flavonoids, saponins, and steroids, while tannins were not detected. These findings indicate that Sansevieria has potential as a source of natural active ingredients for the development of herbal medicines.

Abstract

Abstract:The low level of students' understanding of chemical bonding is caused by the abstract nature of the material and the lack of use of interactive learning media that support concept visualization. In addition, teachers tend to still use conventional printed modules that are considered less interesting. To overcome these problems, this study aims to develop an e-module based on Augmented Reality (AR) technology with a Problem Based Learning (PBL) learning approach on chemical bonding material, as well as to measure the level of validity and student responses to the e-module. This study uses the Research and Development (R&D) method with a 4D development model that includes the Define, Design, Develop, and Disseminate stages. The research subjects were 28 students of class X-2 of SMA Negeri 18 Medan in the 2024/2025 academic year. The instruments used included an interview questionnaire, a validation questionnaire from material and media experts, and a student response questionnaire. The validation results by material experts showed a validity level of 97.1%, while the validation results by media experts showed a validity level of 97.2%, both of which are in the very valid category. Meanwhile, the results of the student response questionnaire for the e-module showed an average score of 91%, which is categorized as very practical. This study demonstrates that the integration of AR technology into the e-module is effective in increasing learning engagement and student understanding of abstract concepts, as well as supporting independent and interactive problem-based learning. Keyword:E-Module, Augmented Reality (AR), Problem Based Learning (PBL), Chemical  Bonding, 4D Development Abstrak: Rendahnya pemahaman peserta didik terhadap materi ikatan kimia disebabkan oleh sifat materi yang abstrak serta kurangnya penggunaan media pembelajaran interaktif yang mendukung visualisasi konsep. Selain itu, guru cenderung masih menggunakan modul cetak konvensional yang dinilai kurang menarik. Untuk mengatasi permasalahan tersebut, penelitian ini bertujuan untuk mengembangkan e-modul berbasis teknologi AugmentedReality (AR) dengan pendekatan pembelajaran Problem BasedLearning (PBL) pada materi ikatan kimia, serta mengukur tingkat validitas dan respon peserta didik terhadap e-modul tersebut. Penelitian ini menggunakan metode Researchand Development (R&D) dengan model pengembangan 4D yang meliputi tahap Define, Design, Develop, dan Disseminate. Subjek penelitian adalah 28 siswa kelas X-2 SMA Negeri 18 Medan tahun ajaran 2024/2025. Instrumen yang digunakan meliputi angket wawancara, angket validasi ahli materi dan media, serta angket respon peserta didik. Hasil validasi oleh ahli materi menunjukkan tingkat validitas sebesar 97,1%, sedangkan hasil validasi oleh ahli media menunjukkan tingkat validitas sebesar 97,2%, keduanya masuk dalam kategori sangat valid. Sementara itu, hasil angket respon siswa terhadap e-modul menunjukkan nilai rata-rata 91%, yang termasuk kategori sangat praktis. Hasil penelitian ini menunjukkan bahwa integrasi teknologi AR dalam e-modul efektif dalam meningkatkan daya tarik pembelajaran dan pemahaman peserta didik terhadap konsep abstrak, serta mendukung proses pembelajaran yang mandiri dan interaktif berbasis masalah. Kata kunci:E-Modul, Augmented Reality (AR), Problem Based Learning (PBL), Ikatan Kimia, Pengembangan 4D
