Studi Efek Tepi Perkebunan Rakyat Terhadap Struktur dan Komposisi Vegetasi di Kawasan Hutan Gunung Sibuatan Kabupaten Karo Sumatera Utara
STUDI EFEK TEPI PERKEBUNAN RAKYAT TERHADAP STRUKTUR
DAN KOMPOSISI VEGETASI KAWASAN HUTAN GUNUNG SIBUATAN
KABUPATEN KARO SUMATERA UTARA
ABSTRAK
Penelitian studi efek tepi perkebunan rakyat terhadap struktur dan komposisi
vegetasi kawasan hutan Gunung Sibuatan Kabupaten Karo Sumatera Utara telah
dilaksanakan pada bulan Desember 2014 sampai dengan Mei tahun 2015. Lokasi
penelitian ditentukan dengan metode purposive sampling dengan membentuk plot
berukuran 60×200 meter yang dibagi menjadi 10 area pengamatan. Analisis
vegetasi dilakukan dengan metode kuadrat, untuk tingkat pohon plot berukuran
20×20 meter, tiang 10×10 meter, pancang 5×5 meter, semai 2×2 meter, dan
tumbuhan bawah 1×1 meter. Hasil penelitian menunjukkan komposisi vegetasi
terdiri dari 38 jenis pohon, 56 jenis tiang, 44 jenis pancang, 24 jenis semai, dan 19
jenis tumbuhan bawah. Dinamika vegetasi memperlihatkan adanya pengaruh efek
tepi sejauh 140 meter dari tepi hutan. Vegetasi pohon, tiang, pancang dan semai
didominasi oleh famili Fagaceae sedangkan tumbuhan bawah didominasi oleh
famili Selaginellaceae.
Kata kunci: Efek tepi, purposive sampling, Struktur dan Komposisi.

STUDY OF EDGE EFFECT OF RESIDENT PLANTATION ON THE
STRUCTURE AND COMPOSITION OF VEGETATION IN THE FOREST
OF MOUNT SIBUATAN KARO DISTRICT, NORTH SUMATRA
ABSTRACT
The study of edge effect of resident plantation on the structure and composition of
vegetation in the forest of Mount Sibuatan Karo district, North Sumatra has been
conducted. Research site was determine using purposive sampling method with
the area measuring of 60x200 meter, subdivided into 10 observation areas.
Vegetation analysis was carried out by applying a square method or plots with
certain sizes which were categorized into tree (20x20 meter) pole (10x10 meter),
sapling (5x5 meter), seedling (2x2 meter), and ground cover (1x1 meter). The
result of this study were consisting of 38 species of tree, 56 species of pole, 44
species of sapling , 24 species of seedling, and 19 species of ground cover. The
dynamics of vegetation showed that edge effect influenced as far as 140 meter
from the edge. Vegetation of tree, pole, sapling and seedling was dominated by
Fagaceae while ground cover was dominated by Selaginellaceae.
Keywords: Edge Effect, Purposive Sampling, Structure and Composition.
