Abstract

Penelitian ini bertujuan untuk mengidentifikasi pohon pakan orangutan di Laboratorium Alam Hutan Gambut (LAHG) yang  berlokasi di utara Taman Nasional Sebangau dengan luas 50.000 ha. Metode yang digunakan yaitu  Point Centered Quarter Method. Jumlah titik cuplikan yang didapat yaitu 25 titik yaitu 10 titik pada transek 0 Secret Barat, 5 titik masing-masing pada transek 0.4 Barat, transek 0.8 Barat dan transek 1.3 Timur dengan jarak masing-masing titik cuplikan yaitu ± 50 meter. Hasil pengamatan ditemukan 54 jenis dari 22 famili, INP tertinggi pada Transek 0 Secret Barat yaitu Bintan untuk tingkat pohon dan  tiang,  Manggis Hutan untuk tingkat pancang.  Jangkang Kuning untuk tingkat pohon pada transek 0.4 Barat, tingkat tiang Pupu Palanduk dan tingkat pancang  Bintan. Transek 0.8 Barat pada tingkat pohon Jinjit, tingkat tiang Tabaras Akar Tinggi dan tingkat pancang Mahadarah Daun Besar. Transek 1.3 Timur pohon Jangkang Kuning, tingkat tiang Jambu Burung Kecil  dan tingkat pancang Mahadarah Daun Kecil. Hasil rata-rata indeks keanekaragaman (H’) tergolong sedang dengan nilai 2,37. Lima jenis pohon pakan yang banyak ditemukan adalah Bintan, Jangkang kuning, Manggis hutan, Pisang-pisang besar dan Malam-malam.

Abstract

This research aims to determine the nest density and population of orangutans and the characteristics of orangutan nests in the Lapak Jaru Grand Forest Park (Tahura), Gunung Mas Regency, Central Kalimantan Province. The method used is strip transect, namely by making a path 1000 m long and 20 m wide on each side of the path and a total of 10 lanes. The calculation results of the average density of orangutan nests at the research location were 30.99 nests/km2 and the Orangutan population is estimated at 29.36 Orangutan individuals. The type of tree where most nests are found is Merawan (Silver sp), Meranti (Shorea sp), and Bumps/Bleeding (Santiria corferta) and based on the most dominant family is the Dipterocarpaceae family. The height of the tree where orangutans nest is 11-15 m with a percentage of 21.67%. The most commonly found diameter of nesting trees is 11-20 cm in diameter with a percentage of 64.67%. The nest height most preferred by orangutans is 16-20 m with a percentage of 28.30%. The most frequently found orangutan nest class is class 3 with a percentage of 35.85% and class 4 with a percentage of 33.96%, and the most frequently found orangutan nest position in the research location is position 2 with a percentage of 37.74%.
