DELENG MACIK TAMAN HUTAN RAYA BUKIT BARISAN
KABUPATEN KARO SUMATERA UTARA
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.
