Abstract

This study aims to evaluate the readiness of pre-service teachers at the Faculty of Tarbiyah and Teacher Training, State Islamic University of North Sumatra, for inclusive education. A mixed-methods approach utilizing an explanatory sequential design was employed to gain a thorough understanding of prospective teachers' knowledge, attitudes, self-efficacy, and concerns about inclusive education. The quantitative poll included 298 students across 10 academic disciplines, of whom 44 were voluntarily selected for the Focus Group Discussion (FGD) session. Quantitative data were collected using an expert-validated questionnaire and analyzed descriptively with SPSS 25.0, while qualitative data were evaluated thematically. The findings revealed that the prospective teachers had favorable attitudes and self-efficacy toward inclusive education; however, they needed to enhance their conceptual knowledge and receive institutional support to be adequately prepared for inclusive learning activities.

Abstract

The green open spaces of Medan State University play a role in biodiversity and ecology. Data collection of fern (Pteridophyta) species in the sporophyte phase and characterization of their sori have not been previously reported, so scientific data collection and presentation are needed. The research method used to obtain data is exploratory. Each fern found was documented and collected for herbarium purposes and detailed sorus observation. Twelve fern species from 7 families were identified: Aspleniaceae, Athyriaceae, Davalliaceae, Nephrolepidaceae, Polypodiaceae, Pteridaceae, and Thelypteridaceae. Of the species found, it was noted that they have terrestrial, epiphytic, and terrestrial/epiphytic life forms. Each species has sori located under the leaf surface, except for Davallia denticulata (Burm.f.) Mett. which is at the leaf tip. The position of the sori is parallel to the leaf veins, between the leaf veins, on the leaf margin, and close to the leaf margin. The sori are brown, light brown, reddish brown, gray, and green. This fern has eight sori, each with an annulus. This sori characteristic differentiates and identifies the type of fern. Pteridophytes in the green open spaces of Medan State University play a role as pioneers, builders of biodiversity and ecosystems, and sources of knowledge, food, and medicine. These findings will serve as a source of scientific knowledge and a basis for characterizing sori elsewhere.

Abstract

Data dan informasi mengenai amfibi di Indonesia masih terbatas, meskipun kondisi hutan relatif terjaga dan berpotensi memiliki keanekaragaman tinggi. Oleh karena itu, diperlukan pembaruan data, termasuk informasi tentang kekayaan dan distribusi jenis amfibi di Hutan Desa Durin Serugun, Kecamatan Sibolangit. Penelitian dilakukan di kawasan hutan tersebut, Kabupaten Deli Serdang (950–1.010 mdpl). Pengumpulan data menggunakan metode Visual Encounter Survey (VES) yang dipadukan dengan jalur purposive pada dua tipe habitat: akuatik dan terestrial. Analisis data dilakukan dengan indeks keanekaragaman Shannon–Wiener, indeks kekayaan jenis Margalef, dan indeks dominansi Simpson. Hasil penelitian menunjukkan bahwa pada habitat akuatik ditemukan 12 jenis dengan 160 individu, sedangkan pada habitat terestrial terdapat 5 jenis dengan 19 individu dari 5 famili. Suhu udara berkisar 21–25 °C dengan kelembaban 99%, kondisi yang sesuai bagi amfibi yang hidup pada lingkungan lembab dan basah. Nilai indeks keanekaragaman (H’) amfibi akuatik (1,943) dan terestrial (1,267) tergolong sedang. Indeks kekayaan jenis (Dmg) akuatik (2,167) dan terestrial (1,358) tergolong rendah, sedangkan indeks dominansi (D) akuatik (0,184) dan terestrial (0,352) juga rendah. Berdasarkan hasil tersebut, dapat disimpulkan bahwa habitat akuatik dan terestrial di Hutan Desa Durin Serugun masih relatif terjaga. Penelitian ini memberikan dasar penting bagi upaya konservasi habitat amfibi serta menjadi sumber data keanekaragaman amfibi di Sumatera Utara.
