ABSTRAK

Penelitian mengenai Komposisi dan Struktur Sapling di Kawasan Deleng Macik
Taman Hutan Raya Bukit Barisan Kabupaten Karo Sumatera Utara telah
dilaksanakan pada bulan Mei 2016 sampai dengan November 2016. Area
penelitian ditentukan secara Purposive Sampling dengan plot berukuran 5x5 meter
sebanyak 100 buah plot dengan susunan zigzag terhadap transek. Hasil penelitian
menunjukkan kekayaan jenis sapling terdapat 79 jenis sapling yang termasuk ke
dalam 37 famili dan 62 marga dengan jumlah 419 individu dimana termasuk 31
jenis yang unik (jenis yang hanya menempati pada satu plot dari jumlah
keseluruhan plot pengamatan). Indeks nilai penting tertinggi terdapat pada jenis
Urophyllum macranthum sebesar 27,11 %, sedangkan jumlah jenis tertinggi
terdapat pada famili Lauraceae. Indeks Keanekaragaman (H’) sebesar 3,777
Indeks Keseragaman (E) sebesar 0.864 dan Indeks Kekayaan Jenis (S) Jackknife
sebesar 109,69.

ABSTRACT

Research entitled Composition and Structure of Sapling at Deleng Macik Region
Taman Hutan Raya Bukit Barisan District of Karo North Sumatera has been
conducted from May to November 2016. The research sites were determined
Purposive Sampling by placing 100 plots of 5 x 5 m with zigzag placement within
each plots. Study found 79 species of sapling which belonged to 37 families and
62 genera with total of 419 individu in which 31 of them were unique to inhabit to
only one plot. The highest Importance Value Index (IVI) were 27,11 % from
Urophyllum macranthum, while highest species found were member of
Lauraceae. Diversity Index (H') found in this study was 3,777. Equitability Index
(E) and Jackknife Species Richness Index (S) were 0,864 and 109,69 respectively.
