ANALISIS VEGETASI TUMBUHAN BAWAH PADA TIGA TIPE
KOMUNITAS KEBUN (STUDI KASUS: KEBUN KOPI, KEBUN KAKAO
DAN AGROFORESTRI DI DESA TELAGAH, KABUPATEN LANGKAT,
SUMATERA UTARA)
ABSTRAK
Analisis Vegetasi Tumbuhan Bawah Pada Tiga Tipe Komunitas Kebun (Studi
Kasus: Kebun Kopi, Kebun Kakao dan Agroforestri di Desa Telagah, Kabupaten
Langkat, Sumatera Utara) telah dilaksanakan pada bulan Maret sampai Mei 2015.
Areal pengamatan ditentukan secara purposive sampling dengan jumlah 40 plot
berukuran 2 x 2 m padamasing-masing lokasi. Diperoleh 80 jenis tumbuhan
bawah yang termasuk kedalam 27 suku. Lokasi 1 didominasi Peperomia
pellucida , lokasi 2 didominasi Paspalum conjugatum dan lokasi 3 didominasi
Leersia hexandra dengan Indeks Nilai Penting secara berurutan yaitu 15,690%,
19,503% dan 28,754%. Indeks keanekaragaman tumbuhan bawah tertinggi
diperoleh di lokasi 1 sebesar 3,307 dan indeks keseragaman tumbuhan bawah
tertinggi juga diperoleh di lokasi 1 sebesar 0,818. Indeks similaritas tumbuhan
bawah tertinggi ditemukan antara lokasi 1 dan 2 sebesar 44,683%.

VEGETATION ANALYSIS OFGROUND COVER AT THREE TYPES OF
PLANTATION COMMUNITY (CASE STUDY: COFFEE ANDCOCOA
PLANTATION AND AGROFORESTRY IN TELAGAH VILLAGE,
LANGKAT DISTRICT, NORTH SUMATRA)
ABSTRACT
Vegetation analysis ofground cover at three types of plantation community (case
study: coffee andcocoa plantation and agroforestry in Telagah Village, Langkat
District,North Sumatra) had been conducted from March to May 2015. The study
area was settled by purposive sampling with 40 plots of 2 x 2 m in size for each
location. There were 80 species of ground cover recorded in the study area
belonging to 27 families. The first location was dominated by Peperomia
pellucida , the second was dominated by Paspalum conjugatum and the third was
dominated by Leersia hexandra with Important Value Index were 15,690%,
19,503% and 28,754%, respectively. The highest diversity and equitability index
also found in the first location with their number were 3,307 and 0,818,
respectively. The highest similarity index was between the first and the second
location with the number was 44,683%.
