Abstract

Abstrak: Problems such as abrasion often make the community alert. This problem is often caused directly by the community itself. The community often forgets or does not know that there are things that can prevent this from happening, such as planting mangrove trees. Therefore, socialization is needed through data by creating a BioMathematics model so that the community can see a simulation of a real phenomenon so that the community is more aware of maintaining and caring for it. This article was done by first modeling the phenomenon that occurs with BioMathematics modeling, then looking for the equilibrium point, Basic Reproduction Number, Stability Theorem, and Numerical Simulation. So that from the model, it can be socialized how to describe a phenomenon and conclusions can be drawn to mitigate risks. The results achieved are that the socialization of BioMathmematics runs smoothly and the community understands that maintaining and caring for mangrove forest resources is very necessary for sustainability. And the community will receive continuous assistance regarding this modeling so that they can be more reliable in seeing the risks that exist in the real world. Kata kunci: Socialization; BioMathematics; Mangrove.  Abstract: Permasalahan seperti abrasi sering membuat kalangan Masyarakat menjadi waspada. Padahal permasalahan ini kerap kali disebabkan langsung oleh masyarakatnya itu sendiri. Masyarakat sering sekali lupa atau tidak tau bahwa ada hal yang dapat mencegah hal tersebut terjadi seperti penanaman Pohon mangrove. Maka diperlukan sosialisasi melalui data dengan membuat model BioMathematics agar bisa melihat simulasi suatu fenomena nyata agar Masyarakat lebih awas dalam menjaga dan merawat. Artikel ini dilakukan dengan memodelkan terlebih dahulu fenomena yang terjadi dengan pemodelan BioMathematics kemudian di cari titik kesetimbangannya, Bilangan Reproduksi Dasar, Teorema kestabilan, serta Simulasi Numeriknya. Sehingga dari model itu bisa disosialisasikan dengan jelas bagimana cara menggambarkan suatu fenomena dan dapat ditarik Kesimpulan untuk bisa memitigasi resiko. Hasil yang dicapai adalah sosialisasi tentang BioMathmematics berjalan lancar dan Masyarakat paham bahwa menjaga dan merawat sumber daya hutan mangrove sangat diperlukan untuk keberlangsungan. Serta masyarakar akan mendapatkan pendampingan terus terkait pemodelan ini agar bisa lebih handal dalam melihat resiko yang ada pada dunia nyata. Keyword: Sosialisasi; Biomathematics; Mangrove.

Abstract

Kaempferia parviflora Wall. ex Baker (Zingiberaceae), commonly known as black ginger, produces dark purple to black rhizomes rich in bioactive compounds. Conventional propagation of K. parviflora is constrained by limited planting material availability. This study evaluated the effectiveness of various cytokinins for in vitro shoot multiplication of K. parviflora. Nodal explants derived from sterile in vitro stock were cultured on Murashige & Skoog medium supplemented with one of seven treatments: P₀ (no cytokinin), P₁ (1 mg L⁻¹ BAP), P₂ (2 mg L⁻¹ BAP), P₃ (1 mg L⁻¹ kinetin), P₄ (2 mg L⁻¹ kinetin), P₅ (1 mg L⁻¹ TDZ), or P₆ (2 mg L⁻¹ TDZ), with ten replicates per treatment. Parameters recorded after eight weeks included explant survival percentage, shoot number, leaf number, and shoot length. Explant survival averaged 94 % across treatments. Treatment P₆ (2 mg L⁻¹ TDZ) yielded the highest mean shoot number (4.9 ± 2.6 shoots) and leaf number (9.3 ± 2.2 leaves) per explant. The superior performance of low‑concentration TDZ compared to BAP and kinetin shows its high efficacy in promoting cytokinin‑mediated shoot proliferation.

Abstract

This study aims to describe the learning interest of An-Nahlu Kisaran Junior High School students in Natural Sciences (IPA). This study uses a qualitative approach with a descriptive method. The research population consisted of all 144 students in grades VII and VIII (5 classes). Data was obtained through a closed questionnaire that measured aspects of learning interest, including feelings of enjoyment, interest, attention, and student participation in science learning. The results of the study show that the majority of students have a good interest in learning, with an average score of 166.0. The results show that 11% (9 students) are very interested, 38% (31 students) are interested, 30% (25 students) are quite interested, 16% (13 students) are less interested, and only 5% (4 students) are not interested in science subjects. Based on gender, there was no difference between the two. Male and female students had the same level of interest in science subjects. Internal factors, such as motivation, curiosity, and attention, as well as external factors, such as support from family, school, and environment, influenced students' level of interest in learning. From the results of this study, it can be said that the learning environment at SMP An Nahlu has supported the development of students' interest in science subjects.

Abstract

Durin Serugun Village Forest, Sibolangit District, North Sumatra is a customary and conservation forest. Located in Deli Serdang Regency and is the headwaters of important rivers in Medan. This area contains a wealth of flora and fauna diversity such as amphibians that have never been published. A study was conducted in April 2025 with a Visual Counter Survey (VES) combined with exploration to obtain data on amphibian species in two habitats; terrestrial (including arboreal and fossorial) and aquatic. The results of the study obtained 15 species of amphibians from 5 families; Bufonidae (4 species), Megophrydae (1 species), Ranidae (4 species), Digroclossidae (5 species), Rhacophoridae (1 species). Three of them are endemic to Sumatra; Chalcorana parvaccola, Sumatrana crassiovis and Rhacophorus catamitus. The report on amphibians in this location is expected to be an important reason for all related parties to take firm and serious steps in protecting and preserving the area and in more in-depth exploration the area has the potential to reveal the existence of amphibian species due to the lack of data in this potential location.

Abstract

The research objectives are: (1) To produce a learning model product for exploring the surrounding natural environment using the forest as a learning resource for students at Leuser Nature School. (2) To find out the practicality level of the EJAS learning model by utilizing the Forest as a learning resource (3) The effectiveness of the E JAS model by utilizing the Forest as a learning resource on improving learning outcomes and environmentally conscious behavior. Research and development Borg and Gall is a study used in developing the EJAS learning model by utilizing the Forest as a learning resource for Leuser Nature School students. Expert validation of the EJAS learning model shows an average value of 91.7% with a very valid category. The results of the trials in all three stages are in the very practical category with an average value of 92.3%. Learning outcomes appear significant with an average learning completion score of 60.92 and an average N-Gain value of 0.609 (moderate to quite high category). Students' environmental behavior has an average of 4.15. So the EJAS model can be an alternative learning strategy that is not only effective in improving cognitive learning outcomes, but also in forming attitudes and character values of Leuser Nature School students.

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.
