STUDI KEBERADAAN MAMALIA DI HUTAN PENDIDIKAN, TAMAN HUTAN RAYA WAN ABDUL RACHMAN

Mamalia memiliki peranan yang sangat penting untuk mendukung ekosistem di kawasan konservasi terutama Tahura WAR. Penelitian ini bertujuan untuk mengetahui keberadaan mamalia di Hutan Pendidikan, Tahura WAR. Metode yang digunakan dalam penelitian yaitu observasi dan wawancara. Hasil penelitian menunjukkan bahwa terdapat 7 spesies mamalia dari 6 famili. Tanda-tanda keberadaan mamalia ditemukan secara langsung maupun secara tidak langsung. Mamalia yang ditemukan secara langsung, yaitu: tupai (Tupaia sp), mamalia yang ditemukan secara tidak langsung, yaitu: babi hutan (Sus scrofa), beruang madu (Helarctos malayanus), monyet ekor panjang (Macaca fascicularis), dan siamang (Hylobates syndactylus), sedangkan mamalia berdasarkan wawancara dengan masyarakat, yaitu: napu (Tragulus napu) dan beruk (Macaca nemestrina). Perjumpaan secara tidak langsung ditandai dengan ditemukannya jejak kaki, kotoran, dan suara. Jenis mamalia yang banyak ditemukan yaitu babi hutan (Sus scrofa). Penelitian lanjutan perlu dilakukan dengan menggunakan kamera trap dan penelitian mengenai keberadaan mamalia nokturnal perlu dilakukan untuk mengetahui lebih banyak spesies mamalia selain yang sudah teridentifikasi.

DAYA DUKUNG DAN PERTUMBUHAN POPULASI SIAMANG (Hylobates syndactylus Raffles, 1821) DI CAGAR ALAM DOLOK SIPIROK, SUMATERA UTARA

<p>Kawasan Cagar Alam (CA) Dolok Sipirok merupakan habitat yang diperkirakan masih mampu mendukung pertumbuhan populasi siamang (<em>Hylobates syndactylus</em>). Penelitian ini bertujuan untuk mendapatkan informasi tentang daya dukung habitat dan model pertumbuhan populasi siamang di CA. Dolok Sipirok, Sumatera Utara. Penelitian dilaksanakan pada hutan primer dan sekunder, mulai dari bulan Maret sampai November 2012. Pengumpulan data produktivitas pakan menggunakan penampung serasah (<em>litter trap</em>) sebanyak 30 buah, pengamatan buah secara search sampling pada plot seluas 6 ha dan telaah literatur untuk data pertumbuhan populasi. Analisis data menggunakan persamaan pendugaan produktivitas, regresi linier, persamaan daya dukung habitat, dan model pertumbuhan logistik. Hasil penelitian menunjukan bahwa rata-rata produktivitas daun di hutan sekunder dan hutan primer berdasarkan hasil pengukuran adalah sebesar 10,4 kg/ha/hari (BB) atau 6,3 kg/ha/hari (BK). Nilai produktivitas buah (mempertimbangkan musim berbuah) rata-rata berkisar antara 6,9 kg/ha per hari (BB) dan rata-rata sebesar 3,2 kg/ha per hari (BK). Nilai dugaan daya dukung antara 579 – 2.249 individu sehingga kondisinya saat ini belum termanfaat secara optimal oleh siamang. Populasi siamang akan mencapai kondisi stabil pada 200 tahun apabila tidak ada perubahan habitat secara drastis di sekitar Kawasan CA. Dolok Sipirok.</p>

Kajian Perilaku Dan Analisis Kandungan Gizi Pakan Drop In Siamang (Hylobates Syndactylus) Di Taman Agro Satwa Dan Wisata Bumi Kedaton

Bumi Kedaton Zoo and Tourism Park is an effort of natural conservation to save animals threatened of extinction, and one of those animals is siamang (Hylobates syndactylus). The objective of this research was to find out behavior and drop in feed nutrition content for siamang by using focal animal sampling method and proximate analysis. Observations were conducted before the cages and in the kitchen where the feed weighting was conducted, so that it would not disturb the animal activities. The result showed that siamang daily behavior in the cage was dominated by locomotion activities; 43.5% and 41.18% for males and females respectively. There were 7 types of feed administered to siamang and muli banana had the highest nutrition content amongst these 7 types of feeds. The nutrition necessity fulfillment for siamang in the cage was not sufficient. Keywords : Siamang, daily behavior, drop in feed, bumi kedaton zoo and tourism park

Studi Kelompok Siamang (Hylobates Syndactylus) Di Repong Damar Pahmungan Pesisir Barat

Repong Damar in Pahmungan, West Coastal District is a buffer of Bukit Barisan Selatan National Park (TNBBS). Repong Damar is one example of the success of agroforestry systems managed by local community that is still very traditional. This area was identified as a component of siamang (Hylobates syndactylus) habitat. The absence of data and the latest information about the siamang groups in Pekon Pahmungan were reasons of this research. The purpose of this research was to determine the siamang groups in Repong Damar, used concentrated area methode. The research was done on April 2015. The results showed that the existence of siamang group in Repong Damar Pahmungan were 4 individuals/group. The distribution of age classes in the individual phases of adult siamang were 2 individuals and the individual of adolescent phase were 2 individuals. The sex ratio in the adult age class phase was 1:1 and at adolescent age class phase was 1:1. Keywords: siamang, groups, repong damar

Peran Siamang (Hylobates Syndactylus) Sebagai Pemencar Biji Di Resort Way Kanan Taman Nasional Way Kambas Lampung

Way Kambas National Parklocated inLampung Provinceis habitat for gibbon (H. syndactylus), frugivorous primate which plays a role as seeds dispersal process in tropical rainforests with its activities. Purpose of the research is to determine the gibbon’s role as seeds dispersal. It was conducted in August 2012 in the Way Kanan Resort of Way Kambas National Park. The method used is exploration and feces analysis.Based on the research, there are 37 samples of gibbon’s feces and 7 spesies of seed plant dispersed by gibbon include Polygonum chinense, Grewia paniculata,Ficus sp, Bouea macrophylla,Dacryodes rostrata, Aporosa aurita, and Aplaia palembanica.Seeds are distributed by gibbon using endozoochory process without destroying seeds and can be dispersed far from the parent trees.Distance of the seed dispersed by gibbons ranges 0−385 meters. Defecation activity of gibbon is done after waking,feeding activity, and when moved to other tree with frequency of defecation between 3−6 times a day. The composition ofgibbon’s feces is seeds and leaves. The highest attendance of seeds in feces is Polygonum chinense seeds (42,12%) and the lowest is Aporosa aurita seeds (1,18%). The mean seeds in feces is7,38 from 273 seeds. Key words : gibbon, seed dispersal, Way Kambas National Park
