Abstract

The village forest of Desa Serdang, Barusjahe, Karo, North Sumatra, is a community-managed forest. This forest exhibits a high species richness comparable to state-conserved and managed tropical rainforests. The orchid group is particularly important to assess in any area, as it generally indicates forest quality with good biodiversity levels. This study employs an exploratory method to reveal 32 orchid species, consisting of 16 terrestrial orchid species from 13 genera and 16 epiphytic orchid species from 11 genera. Descriptions and identification keys for each species are provided in this paper.

Abstract

As Indonesia is known as a megabiodiversity country, and Sumatra is its second largest island, it is important to understand its ever-threatened plant biodiversity, including those managed locally as village forests. In Serdang Village Forest, Barusjahe, Karo, North Sumatra, we tried to list all the liana species and their phorophytes. We conducted a qualitative descriptive analysis of the lianas and their phorophytes in the study area and found There are 25 species of lianas from 14 families Mostly are leaners, followed by tendril climbers, root climbers, hook climbers, thorn climbers and twiners. They climbed on 8 species of phorophyte from 8 families, most commonly tall forest trees. This study enhances our understanding of the lianas and their phorophytes in the Serdang Village Forest, which can aid conservation efforts to preserve biodiversity.

Abstract

Rubiaceae is a common forest plant family in Indonesia, including in many community-managed village forests such as the Serdang Village Forest in Barusjahe, Karo, North Sumatra. A thorough inventory of rubiaceous species is needed to understand their composition and usage by local people. This study aims to list all Rubiaceae species, understand their morphological characteristics, and document their utilization in the village forest. The exploration identified 18 species of Rubiaceae from 12 different genera. Nine species are utilized by the local community: four species as traditional medicine, two species as ornamental plants, one species for firewood, and one species for house/garden posts and household tools. This research enhances the understanding of Rubiaceae species and their uses in the Desa Serdang village forest.

Abstract

This study aims to document the diversity and morphological traits of ornamental plants in Karo Regency and assess their potential for sustainable use. Employing a qualitative descriptive approach, field surveys at Brastagi were conducted at 8 days, morphological observations, and semi-structured interviews with local communities and experts were held with 10 keys conducted. Sixteen ornamental species from 12 families were identified, including terrestrial and epiphytic orchids, ferns, and flowering plants such as Begonia laruei and Ixora javanica. These species are found at elevations of 920–1,000 meters within montane tropical rainforest habitats characterized by high humidity and limited light. Morphological adaptations indicate resilience to these specific conditions. Production data indicate the important economic role of ornamental plant cultivation in Karo Regency. Chrysanthemum, rose, and tuberose are the most widely cultivated species. This reflects their socioeconomic relevance. The integration of botanical and ethnobotanical data provides essential baseline information supporting biodiversity conservation and sustainable horticulture development. This research contributes valuable insights supporting conservation planning and community-based sustainable development in North Sumatra.

Abstract

This study aims to determine the effect of the Numbered Heads Together (NHT) cooperative learning model on students learning outcomes and critical thinking skills in Ecology and Biodiversity material for Grade VII students at SMP Negeri 35 Medan. The research employed a quasi-experimental method using a nonequivalent control group design involving two classes with a total of 64 students, in which the experimental class was taught using the NHT learning model while the control class was taught using a conventional teacher-centered learning model. Data were collected through pretest and posttest instruments, and the improvement in students’ learning outcomes was measured using the normalized gain (N-Gain). The results showed that both classes experienced improvement; however, the experimental class demonstrated a higher increase, with an average N-Gain score of 0.523 categorized as medium, compared to 0.372 in the control class, which was also categorized as medium. Furthermore, the results of the onetailed independent sample t-test showed a significance value of 0.000 (p < 0.05), indicating that the improvement in learning outcomes of students taught using the NHT learning model was significantly higher than that of students taught using the conventional learning model. These findings indicate that the Numbered Heads Together (NHT) learning model has a positive and significant effect on students learning outcomes and can be used as an effective alternative model in science learning, particularly in Ecology and Biodiversity topics. ABSTRAK Penelitian ini bertujuan untuk mengetahui pengaruh model pembelajaran kooperatif Numbered Heads Together (NHT) terhadap hasil belajar dan kemampuan berpikir kritis siswa pada materi Ekologi dan Keanekaragaman Hayati kelas VII di SMP Negeri 35 Medan. Penelitian ini menggunakan metode kuasi eksperimen dengan desain nonequivalent control group yang melibatkan dua kelas dengan jumlah keseluruhan 64 siswa, di mana kelas eksperimen diajar menggunakan model pembelajaran NHT sedangkan kelas kontrol diajar menggunakan model pembelajaran konvensional yang berpusat pada guru. Pengumpulan data dilakukan melalui instrumen pretest dan posttest, sedangkan peningkatan hasil belajar siswa dianalisis menggunakan normalized gain (N-Gain). Hasil penelitian menunjukkan bahwa kedua kelas mengalami peningkatan hasil belajar, namun peningkatan pada kelas eksperimen lebih tinggi dibandingkan kelas kontrol, dengan nilai rata-rata N-Gain sebesar 0,523 pada kategori sedang, sedangkan kelas kontrol memperoleh nilai rata-rata N-Gain sebesar 0,372 yang juga termasuk kategori sedang. Selanjutnya, hasil uji independent sample t-test satu arah menunjukkan nilai signifikansi sebesar 0,000 (p < 0,05), yang menunjukkan bahwa peningkatan hasil belajar siswa yang diajar menggunakan model pembelajaran NHT secara signifikan lebih tinggi dibandingkan dengan siswa yang diajar menggunakan model pembelajaran konvensional. Berdasarkan hasil tersebut, dapat disimpulkan bahwa model pembelajaran Numbered Heads Together (NHT) berpengaruh positif dan signifikan terhadap hasil belajar siswa serta dapat digunakan sebagai alternatif model pembelajaran yang efektif dalam pembelajaran IPA, khususnya pada materi Ekologi dan Keanekaragaman Hayati.

Abstract

This study aims to identify the species of the Zingiberaceae family found in the Durin Serugun Village Forest and determine their potential use by the local community, especially in the food and health sectors. The methods used were field exploration, interviews with the Karo people, phytochemical tests to detect secondary metabolites in Zingiberaceae rhizomes, and dendogram analysis to determine the phylogenetic relationships between species. The results showed that there are 13 Zingiberaceae species with morphological characteristics and secondary metabolite content such as alkaloids, saponins, tannins, and flavonoids. The community uses rhizomes for traditional medicine to treat various diseases and as a kitchen spice. Dendogram analysis divided the species into two main clusters that reflect morphological similarities and phylogenetic relationships. This study provides an overview of traditional uses as well as the conservation value of Zingiberaceae diversity in the area.
