Abstract

Penelitian ini bertujuan untuk mengetahui variasi morfologi edelweis (Anaphalis spp.) dan mengetahui faktor fisika-kimia lingkungan di Kawasan Sekitar Danau Toba. Penelitian telah dilaksanakan di daerah dataran tinggi dengan ketinggian 1000-2000 mdpl. (Meter di atas permukaan laut) yaitu Gunung Pusuk Buhit, Kabupaten Samosir, Bukit Sipiso-piso (Kabupaten Karo), Taman Eden, (Kabupaten Toba Samosir). Metode yang di lakukan adalah dengan metode explorasi. Sampel yang di amati karakter morfologi dan juga mencari faktor fisika-kimia lingkungan berupa pH tanah, kelembapan udara, suhu udara, ketinggian, suhu tanah dan struktur tanah. Jenis edelweis yang di peroleh dari ke 3 lokasi penelitian hanya 1 jenis yaitu (Anaphalis longofilia) (Blume) Blume ex DC. Berdasarkan cluster analysis atau Analisis Gerombol menggunakan software NTSYS, Edelweis (Anaphalis) di 3 lokasi penelitian (Gunung Pusuk Buhit, Bukit Sipiso-piso, Taman Eden) terbagi menjadi 3 kelompok dan memiliki variasi morfologi yang rendah dengan memiliki nilai kesamaan morfologi 0,80 (80%). Seluruh sampel memiliki nilai similaritas di atas 60%, hal ini menunjukkan bahwa kelompok tersebut di kategorikan masih dalam 1 spesies. Hasil pengukuran faktor fisika-kimia lingkungan di 3 lokasi penelitian, diperoleh ph tanah 6-8, kelembapan udara 70-76%, suhu udara 26-310C. Edelweis (Anaphalis) ditemukan di ketinggian antara 1234-1889 mdpl. dengan tekstur tanah lempung berpasir.

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.
