This research aims to compare the effectiveness of offline and online learning systems on inheritance topic in grade 11 high school students of MAS Kanjeng Sepuh in terms of student learning outcomes, student responses, and management of learning process. Online learning carried out by using the Whatsapp, Google Classroom and Google Meet applications, while offline learning was carried out face-to-face in the classroom. The design of this study used a Quasi Experimental Design with a Non-equivalent control group design type. This research was conducted at MAS Kanjeng Sepuh with a total of 24 students from class 11 IPA 1 and 11 IPA 2. The sampling technique used was saturation sampling. The results of the research showed that there were no significant differences in learning outcomes before and after online learning, but significant differences were found in learning outcomes before and after offline learning. Students showed more positive responses to the offline learning system than the online learning system. In addition, the management of learning process in online and offline learning was in the good and excellent categories so that they were equally effective. Therefore, it can be concluded that the offline learning system was more effective than the online learning system in terms of learning outcomes and student responses. Meanwhile, in term of the management of learning process, offline and online learning systems were equally effective. Both online and offline learning systems have their advantages and disadvantages that affect the effectiveness of learning, so more attention is needed to minimize the disadvantages of each learning system, especially online learning systems so that the learning process can be more optimal. Keywords: online learning, offline learning, learning outcomes, student responses, high school

This research aims to develop an e-book that explores biodiversity through the lens of the Telaga Sarangan Larung Tumpeng tradition, integrating local wisdom to enhance students' argumentation skills. Utilizing a development research method, the study follows the ADDIE framework, which consists of analysis, design, development, implementation, and evaluation phases. The data analysis technique employs validation tests and readability assessments for the e-book development outcomes, analyzed using a qualitative descriptive approach. The research utilized an e-book validation sheet evaluated by two lecturersâ€”one an expert in content and the other in educational methods. Additionally, a readability test was conducted using Fry graphs. The validation results yielded an average score of 3.9, categorizing the e-book as very valid. This evaluation took into account various aspects such as presentation validity, content validity, and language validity. Additionally, the practicality of the e-book is evaluated through a readability test, which indicates a reading level appropriate for tenth-grade students. The e-book achieved a readability level of 12, classified as very positive and suitable for its intended audience. The study clearly demonstrated that the e-book focused on biodiversity, grounded in the local wisdom of the Larung Tumpeng tradition at Telaga Sarangan, is both valid and practical for enhancing the argumentation skills of X-grade high school students.

Pesatnya perkembangan teknologi di abad ke-21 menuntut penguasaan literasi digital sebagai kompetensi esensial bagi siswa. Namun, literasi digital siswa SMA di Indonesia masih tergolong rendah. Penelitian ini bertujuan mengembangkan e-book pada materi virus untuk meningkatkan literasi digital siswa yang layak berdasarkan aspek validitas, kepraktisan, dan keefektifan. Penggunaan e-book untuk materi virus dianggap mampu mengatasi karakter materi yang abstrak, kompleks secara konseptual, dan berpotensi menimbulkan miskonsepsi. Materi ini dipilih karena memuat banyak istilah teknis yang memerlukan fitur glosarium dan visualisasi untuk memudahkan pemahaman. Perkembangan virologi yang dinamis menuntut pembaruan cepat dan relevansinya dengan kehidupan siswa. Penelitian ini menerapkan metode Research and Development (R&D) guna menciptakan produk sekaligus menguji efektivitas produk. Penelitian menggunakan model pengembangan 4D (define, design, develop, disseminate). Data diperoleh melalui validasi ahli, angket respon siswa, uji keterbacaan, serta tes pre-test dan post-test. Subjek penelitian berjumlah 28 siswa kelas X SMA Muhammadiyah 3 Tulangan. Hasil penelitian menunjukkan bahwa e-book yang dikembangkan terintegrasi fitur interaktif Viclips, Vinfo, Viquiz, Viktos, dan Vissue untuk melatih indikator literasi digital. Hasil validasi memperoleh persentase rata-rata 97,45% dengan kategori sangat valid. Uji kepraktisan berdasarkan grafik Fry menunjukkan tingkat keterbacaan level 10, dan angket respon siswa memperoleh 98,8% dengan kategori sangat praktis. Keefektifan e-book ditunjukkan oleh peningkatan hasil belajar dengan skor N-gain 0,74 dengan kategori tinggi dan pencapaian ketuntasan belajar 100%. Simpulan penelitian ini adalah e-book materi virus yang dikembangkan dinyatakan valid, praktis, dan efektif untuk meningkatkan literasi digital siswa.

The glyphosateâ€™s continuous application in agricultural fields has caused adverse environmental effects. Utilizing indigenous microorganisms as glyphosate-degrading agents can be an effective and eco-friendly solution. Isolate Cf2, obtained from a local chili pepper plantation in Indonesia, grew as a co-dominant isolate in media with 50 ppm glyphosate, indicating its potential as glyphosate-degrading bacteria. However, this isolate cannot be applied yet because it has not been identified. Identification can provide initial insights into the safety of indigenous isolates for ecological application. Thus, this study aims to identify isolate Cf2 by utilizing the 16s rRNA gene sequence as the genetic marker. The data was compared to the database using the web-based BLAST2 program (version 2.13.0). Then, the evolutionary relationship of this isolate with its closest relatives was assessed through phylogenetic tree reconstruction. The results demonstrate that the isolate Cf2 has a sequence similarity of 98.88% with Bacillus subtilis. The phylogenetic tree reconstruction further indicates that isolate Cf2 forms a monophyletic clade with this species. Hence, it can be concluded that isolate Cf2 is indeed B. subtilis. This study is the first report of glyphosate-degrading B. subtilis isolated from chili pepper plantations in Indonesia, offering a new insight into bioremediation strategies.

Environmental safety and public health are greatly influenced by the microbiological elements such as bacterial community, where these organisms can be used as indicators of environmental quality and sources of potential biological hazards. The identification of bacteria in wastewater is an important aspect of environmental microbiology studies. The purpose of this study was to identify the bacterial species in food court wastewater at State University of Surabaya (UNESA) Campus 1. The methods used were exploratory, including bacterial cultivation, DNA extraction, quantitative and qualitative DNA analysis, amplification of 16S rRNA gene fragments, sequencing, and phylogenetic tree reconstruction. From phylogenetic analysis, five test isolates were related to the families Enterobacteriaceae, Aeromonadaceae, Chromatiaceae, and Halomonadaceae. Isolates BU4 and BU5 were most closely related to genus Aeromonas with a similarity of 98.60% and 97.27%, respectively, while isolate BU3 was closely related to genus Klebsiella with a similarity of 96.91%. Meanwhile, isolates BU1 and BU2 cannot yet be identified into a bacterial genus. The results of this study provide important information regarding the prediction of pathogenic bacteria types, which can serve as the basis for recommending further action to prevent disease, improve water quality, and increase the sterility of the food court area.
