Abstract

The students’ higher order thinking skills were still low due to the learning system, such as the use of textbooks that have not led to an increase in higher order thinking skills. The availability of updated textbooks based on higher order thinking skills was needed in the university. The aim of this study was to develop a textbook based on higher order thinking skills on animal physiology course. The development model used in this study was the Thiagarajan (4D) development model which consisted of define, design, development and dissemination. However, the research stage carried out was only up to development. The developed textbook was validated based on three criterias, namely material, language and design. The developed textbook was also tested to students who have taken animal physiology course and obtained the students’ response. The result of validation by material expert was 86 in the category of “Very Good”, language expert was 88 in the category of “Very Good”, design expert was 87 in the category of “Very Good” and students’ response according to individually, small group and limited group were 86, 89 and 89 respectively. The whole students’ responses were categorized as “Very Good”. It can be concluded that the product can be used as a textbook in animal physiology course. This study is useful as a learning source for students and an alternative teaching material for lecturers, as well as improving the quality of animal physiology learning.

Abstract

ABSTRACK This study aims to identify the endophytic fungus from the bark of the plant raru (Cotylelobium melanoxylon). This study uses identification technique manually by viewing and comparing the macroscopic and microscopic morphological characteristics of each isolate endophytic fungi then seek to obtain dendogram similarity index which divides each isolate into several clusters/genus. Data were analyzed using cluster analysis Simple Matching Coefficient in the Multi Variate Statistical Package (MVSP) where each isolate that had ≥70 % similarity indices are grouped into one cluster/genus. The results of cluster analysis to get 8 cluster/genus endophytic fungi found in the bark of plants raru (Cotylelobium melanoxylon). Eighth genus included the genus Alternaria, Aspergillus, Botrytis, Debaromyces, Fusarium, Mycelia sterile, Nigrospora, and Scopulariopsis. This paper presents a description of the genus Botrytis. Kata Kunci: Identifikasi, Jamur Endofit, Cotylelobium Malanoxylon,  Indeks Similiritas

Abstract

Street food remains a popular choice for students due to its affordability and convenience. Its rapid preparation and service contribute to its ongoing popularity. The university, including Universitas Negeri Medan, is often surrounded by numerous street vendors offering a diverse range of foods, predominantly made from meat and flour. However, the open exposure of these foods and insufficient sanitation practices pose a heightened risk of contamination by harmful microorganisms. This study examines bacterial contamination in processed meat-based street foods sold near Universitas Negeri Medan, with a focus on items such as meatballs, grilled meatballs, and batagor. Microbiological examination involved isolating bacteria using selective and differential culture media, particularly Eosin Methylene Blue Agar (EMBA). Subsequent identification was carried out using Gram staining to determine cell morphology and SIM (Sulfide Indole Motility) medium for motility assessment in the microbiology lab at Universitas Negeri Medan. Findings revealed contamination predominantly in grilled meatballs, with bacteria belonging to the Enterobacteriaceae family detected. These isolates were characterized as Gram-negative, rod-shaped, and motile microorganisms. The presence of such bacteria raises serious concerns about food safety. It emphasizes the need for improved hygienic practices and rigorous food safety control measures in street food vending areas around the university. Implementing these measures is essential to safeguard student health and maintain the standard of street food quality on campus.

Abstract

Background: STEM learning can help students understand science concepts, improve science skills, create active, creative, motivating learning and provide opportunities for students to apply the material and build their knowledge. This research aims to develop valid and reliable science, technology, engineering and mathematics-based student evaluation tools on fungi material. Methodology: The evaluation instrument was developed using the 4D development model, which includes four stage: Define, Design, Develop and Determine. The study involved 30 first-grade students from MAS Madinatussalam, North Sumatra. The developed evaluation tool consisted of 40 questions. Validation by industry experts confirmed the instrument’s validity and reliability. Findings: Expert evaluations of the questions indicated high suitability, with an average score of 96.75%. Material experts rated the instrument with a suitability score of 92.5%, while media experts gave an average score of 86.1%, all falling within the "very good" category. Reliability testing using Cronbach's Alpha yielded a score of 0.886, indicating high reliability. Based on these results, the STEM-based evaluation tool is considered both valid and reliable for classroom use. Contribution: Expected to provide information as a basis for consideration, supporting the improvement of problem solving skills, increasing critical and creative thinking skills

Abstract

Kegiatan Pengabdian kepada Masyarakat (PkM) ini dilatarbelakangi oleh belum optimalnya pengelolaan limbah daun di Sekolah Syarif Ar Rasyid Kota Binjai yang selama ini dilakukan dengan pembakaran, sehingga menimbulkan masalah baru berupa pencemaran udara. Hal ini juga sejalan dengan hasil observasi rendahnya literasi etnosains siswa yaitu 90% siswa hanya mengetahui kertas dari kayu pohon. Tujuan kegiatan adalah mengimplementasikan teknologi tepat guna berbasis teknik Daluang untuk mengolah limbah daun menjadi kertas, meningkatkan literasi lingkungan, serta menumbuhkan life skill siswa. Metode pelaksanaan meliputi tiga tahap: (1) Focus Group Discussion (FGD) untuk audit vegetasi dan sinkronisasi kurikulum; (2) sosialisasi dan pelatihan implementasi IPTEKS melalui demonstrasi pembuatan pulp (pencacahan dengan mesin mini cooper 200 watt, perebusan dengan campuran 100 gr soda kue dan 900 mL air selama 15 menit, pemukulan serat, penambahan air kanji, pencetakan, dan pengeringan); (3) pendampingan dan evaluasi mutu. Hasil kegiatan menunjukkan: (a) reduksi volume limbah daun sebesar 70% dari 5–15 kg per minggu; (b) peningkatan life skill siswa dengan rerata capaian 3,4 (skala 4,0) yang mencakup kecakapan personal (3,8), sosial (3,5), akademik (3,0), dan vokasional (3,3); (c) keberhasilan produksi kertas dari berbagai bahan (daun kering, rumput, sampah kertas) daun kering memerlukan konsentrasi soda kue dan perebusan yang lebih lama; (d) terintegrasinya kearifan lokal teknik Daluang dalam pembelajaran kontekstual. Transformasi limbah selulosa daun melalui teknologi pulping berbasis etnosains Daluang tidak hanya menyelesaikan masalah ekologi sekolah tetapi juga efektif menumbuhkan kecakapan hidup siswa serta melestarikan warisan budaya Nusantara. Kegiatan ini juga mendukung pencapaian SDGs poin 4 (pendidikan berkualitas) dan poin 12 (konsumsi dan produksi bertanggung jawab).
