Abstract

Kuta Panang is a sub-district in Central Aceh Regency, Aceh Province, Indonesia. Weh Nongkal Toa Village is one of the villages in Kuta Panang District with an area of ± 19,000 ha of Weh Nongkal Toa village. This study aims to identify the morphological characters of the rattan species that produces Daemonorops spp. and analyzing and comparing the significant differences in the morphological characters of Daemonorops spp. The object of the research was the rattan producing jernang ( Daemonorops spp.) Which consisted of three types, namely Daemonorops draco (Wild.) Blume, Daemonorops mattanensis Becc,Daemonorops didymophylla Becc. The method used in this research is to use qualitative and quantitative data research variables in which there are morphological characters in, 1). stem; (upright, plant height, stem diameter, number of stems, the length of the stem, stem color, segment length ( Internode ). 2). leaf; (leaf length, number of leaves, leaf color). 3). fruit; (fruit color, fruit diameter, number of fruits). 4). thorns; (thorn position, shortest thorn length, longest thorn, thorn color). ANOVA analysis was used as an analytical tool to test the research hypothesis whether there was an average difference between groups and the Bnt test to obtain the smallest significant difference. The results of quantitative data on stem height: D. draco 4 - 6 m, D. mattanensis 2 - 4 m,D. didymophylla 1 - 3 m, the length of the bunch, namely D. draco 3 - 4 m, D. mattanensis 1 - 3 m, and D. didymophylla 1 - 2 m. Stem diameter: D. draco 6-8 cm, D. mattanensis 3-6 cm, and D. didymophylla 1-3 cm. Internodes length: D. draco 15 - 40 cm, D. mattanensis 10 - 35 cm and D. didymophylla 8 - 30 cm. Leaf length: D. draco 30-45 cm, D. mattanensis 30-38 cm, and D. didymophylla 26-30 cm. Fruit diameter: D. draco 4 - 6 cm, D. mattanensis 2 - 4 cm, andD. didymophylla 2 - 3 cm. Long spines: D. draco 2 - 4 cm, D. mattanensis 2 - 3 cm, and D. didymophylla 1 - 2 cm. ANOVA test that was significantly different, namely the quantitative morphological characters of stem height, stem diameter length, bunch length, internode length, leaf length, and fruit diameter showed significantly different results between the three types of rattan producing jernang ( Daemonorops spp.), Whereas Morphological characters on the number of stems, number of leaves, number of fruit, length of the shortest thorn, and length of the longest thorn showed no significant difference between the three types of Daemonorops.spp. The very significant LSD test was the quantitative morphological characters of stem height, stem diameter, bunch length, internode length, leaf length, and fruit diameter.

Abstract

 Abstrak. Orangutan sumatera (Pongo abelii) merupakan spesies langka yang dilindungi dan telah dimasukkan oleh International Union for Conservation of Nature and Natural Resources (IUCN) ke dalam kategori satwa yang berstatus krisis atau “critically endangered”. Berbagai kegiatan manusia yang menyebabkan luasan habitat orangutan terus berkurang, seperti pembalakan liar dan perambahan hutan. Oleh karena itu perlu dilakukan upaya untuk mempertahankan keberlangsungan hidup orangutan sumatera (Pongo abelii) khususnya di Kawasan Ekosistem Leuser (KEL) melalui penyediaan informasi mengenai karakteristik sarang orangutan sebagai acuan dalam rangka konservasi orangutan. Penelitian ini bertujuan untuk mengidentifikasi dan menganalisis karakteristik pohon sarang orangutan sumatera (Pongo abelii) di Stasiun Penelitian Soraya. Penelitian menggunakan metode transek pada tiga transek dengan panjang 1 km dan lebar (50 m ke kanan dan 50 m ke kiri). Jumlah sarang yang ditemukan adalah sebanyak 27 sarang dengan jenis pohon yang mendominasi sebagai sarang orangutan adalah pohon Streblus elongatus dan Syzigium spp. dengan jumlah masing-masing 4 pohon (15%). Rata-rata tinggi pohon sarang dari permukaan tanah adalah 17,47 m, dan tinggi sarang antara 15,25 m, tinggi pohon sarang dengan tinggi sarang memiliki hubungan yang kuat. Rata-rata diameter pohon sarang yaitu 13,37 - 35,17 cm. Semakin besar berat badan orangutan tersebut maka semakin besar pula diameter yang dipilih orangutan sebagai pohon sarang. Karakteristik sarang berdasarkan kelas sarang yang paling banyak ditemukan adalah pada kelas C (sarang sudah lama dan sebagian daun sudah layu dan hilang serta terlihat lubang-lubang kecil) yaitu sebanyak 18 sarang, sedangkan posisi yang paling banyak ditemukan adalah posisi 3 (sarang berada pada ujung atau pucuk pohon utama) dengan jumlah sebanyak 13 sarang.Characteristics of Sumatran Orangutan (Pongo abelii) Nest at the Soraya Research Station, Leuser EcosystemAbstract. Sumatran orangutan (Pongo abelii) is a rare species that is protected and has been included by the International Union for Conservation of Nature and Natural Resources (IUCN) in the category of critically endangered animals. Various human activities that cause the orangutan habitat area continues to decrease, such as illegal logging and forest encroachment. Therefore it is necessary to make efforts to maintain the survival of sumatran orangutans (Pongo abelii) especially in the Leuser Ecosystem (KEL) by providing information on the characteristics of orangutan nests as a reference in the conservation of orangutans. This study aims to identify and analyze the characteristics of the Sumatran orangutan nest tree (Pongo abelii) at the Soraya Research Station. The study used a transect method on three transects with a length of 1 km and width (50 m to the right and 50 m to the left). The number of nests found was as many as 27 nests with tree species that dominated as orangutan nests were Streblus elongatus and Syzigium spp. with a total of 4 trees (15%) each. The average height of the nest tree from the ground surface is 17,47 m, and the nest height is 15,25 m, the height of the nest tree with the height of the nest has a strong relationship. The average diameter of the nest tree is 13,37-35,17 cm. The greater the weight of the orangutan, the greater the diameter the orangutan chooses as a nest tree. The characteristics of nests based on the nest class most commonly found are in class C (nests are old and some leaves have withered and disappeared and there are small holes visible) as many as 18 nests, while the position most commonly found is position 3 (nest is at the end or the main tree shoots) with a total of 13 nests.
