Karakteristik Sarang Orangutan Sumatera (Pongo Abelii) Di Kawasan Hutan Sekunder Resort Sei Betung Taman Nasional Gunung Leuser

KARAKTERISTIK SARANG ORANGUTAN SUMATERA (Pong abelii)
DI KAWASAN HUTAN SEKUNDER RESORT SEI BETUNG
TAMAN NASONAL GUNUNG LEUSER

ABSTRAK

Orangutan merupakan satwa yang terancam punah keberadaanya di dunia. Salah
satu habitat orangutan Sumatera di TNGL adalah hutan sekunder Resort Sei
Betung. Orangutan ditemukan beraktivitas dan bersarang di hutan tersebut.
Penelitian mengenai “Karakteristik Sarang Orangutan Sumatera (Pong abelii) Di
Kawasan Hutan Sekunder Resort Sei Betung Taman Nasonal Gunung Leuser”
telah dilaksanakan pada bulan Juli-Agustus 2014. Penelitian ini bertujuan untuk
mengetahui karakteristik sarang orangutan Sumatera berdasarkan kelas sarang,
posisi sarang, ketinggian sarang dan pohon tempat bersarang. Penelitian ini
menggunakan metode Line Transect secara Random Sampling. Dari hasil
penelitian didapatkan Persentase kelas sarang paling tinggi berturut-turut adalah
kelas D (24%), kelas E (22%), kelas B (22%), kelas C (20%) dan kelas A (12%).
Persentase posisi sarang terbanyak berurut-turut adalah posisi 3 (46%), posisi 2
(26%), posisi 1 (20%) dan posisi 4 (8%). Ketinggian sarang mulai dari 3-25m,
ketinggian terbanyak berturut-turut adalah ketinggian 6-10m (54%), 11-15m
(28%), 16-20m (9%), 0-5m (8%) dan 21-25% (2%). Karakteristik berdasarkan

jenis pohon tempat bersarang ditemukan sebanyak 15 family dan 27 spesies yang
didominasi oleh faimily Euphorbiaceae (31%) dan Lauraceae (11%) dan spesies
yang paling mendominasi adalah Endospermum diadenum dan Macaranga lowii

CHARACTERISTIC OF NEST SUMATERAN ORANGUTAN (Pongo
abelii) IN SECONDARY FOREST IN SEI BETUNG RESORT OF
GUNUNG LEUSER NATIONAL PARK

ABSTRACT

Sumatran orangutans are critically endangered species and one of their most
viable habitat is Gunung Leuser National Park (GLNP) in northern Sumatra.
Within the GLNP, secondary forest in Sei Betung resort is also considered as an
important habitat for Sumatran orangutan and other species. In this secondary
forest, orangutans were found roaming and nesting. The research entitled

“Characteristic Of Nest Sumateran Orangutan (Pongo abelii) in Secondary Forest
in Sei Betung Resort of Gunung Leuser National Park” was conducted from July
to August 2014. The purpose of this research is to identify the characteristic of
nest made by Sumatran orangutan based on nest class, nest position, nest altitude
and nest tree. The result of the research shows that the nest classes is dominated
by class D (24%) followed by class E (22%), class B (22%), class C (20%) and
class A (12%). Percentage of the nest position is dominated by position 3 (46%)
followed by position 2 (26%), position 1 (20%) and position 4 (8%). The altitude
of nests ranges from 0-25m, with 54% is located at altitude of 6-10m , 28% is at
11-15 m, 9% is between 16-20m, 8% is 0-5m, and only 2 % is at 21-25 m.
Characteristics based on the type of nesting tree found on 15 tree family and 27
tree species of which dominated by Euphorbiaceae (31%) and Lauraceae (11%).
The most dominated species for nest making is Endospermum diadenum and
Macaranga lowii.
