EFEK TEPI PADA POPULASI ORANGUTAN KALIMANTAN (Pongo p. morio) DI JALUR WISATA PREVAB DAN SANGKIMA TAMAN NASIONAL KUTAI

Alqaf Alqaf, Yaya Rayadin

Abstract


Kawasan Prevab dan Sangkima merupakan daerah sebaran populasi dan habitat orangutan di Taman Nasional Kutai. Kondisi lingkungan habitat tersebut memiliki karakteristik yang berbeda dengan kondisi lingkungan di hutan. Penelitian ini dilakukan untuk mengetahui respon efek tepi terhadap Orangutan di kawasan wisata Sangkima dan Prevab. Respon efek tepi dianalisis berdasarkan perilaku bersarang Orangutan pada habitat tepi di sungai Sangata dan jalan utama Bontang-Sangata. Survei sarang orangutan dilakukan dengan metode transek sepanjang 1.000 m. Estimasi populasi orangutan kemudian dikalkulasikan. Kualitas habitat dianalisis menggunakan metode plot vegetasi 25 unit (20 m x 20 m). Estimasi populasi orangutan di wilayah Prevab adalah 246 individu (95% atas = 285 ind. & 95% bawah = 212 ind) dan Sangkima adalah 619 individu (95% upper = 688 ind dan 95% lower = 557 ind.). Kondisi habitat orangutan terdiri dari 122 jenis pohon, dimana 80 jenis pohon pakan ditemukan di Prevab dan 70 jenis ditemukan di Sangkima. Efek tepi dibuktikan dengan kecenderungan Orangutan membuat sarang lebih banyak mengarah ke bagian tepi hutan di wilayah Prevab maupun Sangkima.
