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.
