Abstract

Kedih (Presbytis thomasi) merupakan satwa primata endemic Sumatera, yang sebarannya terbatas di wilayah Aceh dan sebagian kecil Sumatera Utara. Populasi spesies ini sangat terancam karena habitatnya banyak mengalami gangguan, terutama kebakaran hutan. Penelitian ini bertujuan untuk mengetahui komposisi kedih di Cagar Alam Pinus Jantho (CAPJ) pada blok rehabilitasi dan blok perlindungan, dengan luas lokasi penelitian 184hektar. Penelitian dilakukan sejak Desember 2017 sampai September 2018. Metodologi penelitian pada pengamatan kedih menggunakan line transect sampling dan scan sampling untuk mengidentifikasi strata tajuk yang digunakan kedih untuk istirahat dan tidur. Jumlah jalur sebanyak 23 transek dengan panjang bervariasi antar jalur. Dari hasil pengamatan, ditemukan 7 kelompok kedih dengan total jumlah individu 34 ekor yang terdiri dari 8 jantan dewasa, 9 betina dewasa, serta 12 remaja dan 5 anak. Struktur umur kedih di CAPJ termasuk dalam kategori struktur umur stabil dibuktikan dengan umur kedih muda (anak+remaja) sama jumlahnya dengan kedih dewasa. Nisbah kelamin jantan dan betina dewasa 1:1,12 dan usia muda (anak dan remaja) dan dewasa 1:1. Strategi konservasi yang dapat dilakukan untuk pelestarian dan perlindungan kedih adalah dengan melakukan perbaikan habitat melalui pengayaan jenis vegetasi, peningkatan pengawasan terhadap kebakaran hutan dan kehadiran pemburu satwa, serta pembinaan terhadap masyarakat sekitar kawasan melalui penyuluhan dan pendidikan konservasi.

Abstract

 The research was conducted after tsunami destroyed mangrove in Aceh Besar coastal area, whichserves as waterfowl habitat. This study was aimed to find out bird diversity and abundant after tsunamidisaster. The study was conducted in Kecamatan Mesjid Raya, Aceh Besar, focusing on bird biodiversityand its number based on habitat type, using count dot survey technique. The study revealed that as manyas eight waterfowl species from four families were found. The variety of bird species in the researchlocation was low, ie; 1.2196 for fish pond, 1.7257 for muddy land, and 1.2528 for vegetation area. The lowlevel of biodiversity indicated fragmented habitat in the mangrove area.Keywords: mangrove conservation, bird biodiversity index, bird conservation

Abstract

Thomas langur (Presbytis thomasi) is an endemic primate to Aceh and North Sumatra. These primates have a local name, “Kedih.” Forest fires and forest functions conversion into oil palm plantations are pressure on their habitat and have decreased wild populations in nature. As arboreal animals, their movements depend heavily on the connectivity of vegetation. Comprehensive research is needed to obtain horizontal and vertical daily movement data of the thomas langur. This study used GPS to take coordinates, a camera to document Thomas langur and its food trees, and Thomas langur as a research object. The data recorded includes the coordinates of each forage tree, the type of forage tree, and the height of the canopy strata used by Thomas langur for foraging. The hardwood movement data was plotted on ArGis 10.1 to get the horizontal hardness movement area. Tree height data was obtained by measuring the tree height where Thomas langur stopped to look for food. Kedih movements to look for food are carried out daily from morning to evening. The results showed that the short length of movement was highly depend on the availability of forage trees. The denser the forage trees, the shorter the daily activities of Thomas langur. This daily movement can be done horizontally and vertically. Horizontally, Thomas langur moved to follow the forage trees, and vertically, Thomas langur moved by utilizing the height of the forage trees. Horizontally, Thomas langur moved 144.92 m in the rehabilitation block and 62.30 m in the protection block. The Thomas langur home ranged in the rehabilitation block is 27 ha, and 25 ha in the protected block. Vertically, Kedih in the rehabilitation blocks and protected blocks moved to trees with a height of 11-20 m, as much as 49%.
