Memahami umur satwa merupakan aspek penting untuk mengidentifikasi struktur umurnya. Struktur umur adalah salah satu parameter demografik yang penting untuk dipelajari terkait tujuan pengelolaan populasi. Salah satu teknik estimasi usia dapat didekati dari ukuran organ (morphometric). Penelitian ini dilakukan dari Mei hingga Agustus 2007 pada Pusat Penyelamatan Satwa Cikananga, Jawa Barat dan Kalaweit Pusat, Sumatera Barat. Penelitian ini menggunakan 14 parameter dan 40 sampel dari siamang (Symphalagus syndactylus Raffles, 1821), terdiri dari 24 jantan dan 16 betina. Hasil analisis statistik (regresi linier berganda dengan metode bertahap) korelasi antara umur (Y) dengan lingkar wajah (LM) diperoleh persamaan regresi untuk Umur = -14,546 + 0,801 LM untuk jantan (1-15 tahun), panjang tangan (PTT) dengan Umur = -2,091 + 0,496 PTT untuk jantan (1-6 tahun), lingkar dada (LD) dengan Umur = -15,328 + 0,533 LD untuk betina (2-14 tahun), lingkar dada dengan Umur = -5,331 + 0,312 LD untuk jantan dan betina (1-15 tahun). Ukuran morfologikal dalam hal ini lingkar wajah, panjang tangan, lingkar dada merupakan pertumbuhan panjang hewan yang mudah dilihat dengan mata dan merupakan parameter penentuan kelas umur pada siamang sumatera (Symphalagus syndactylus Raffles, 1821). Parameter morfometrik yangdigunakan merupakan bagian-bagian tubuh yang mudah terlihat dan mudah diukur dan merupakan bagian terpenting dalam sebuah teknik penentuan umur menggunakan metode morfometrik.

Macaca ochreata is one of Sulawesi endemic primates, which are distributed only in Southeast Sulawesi. This study aimed to identify habitat characteristics and estimated Macaca ochreata population was conducted in February until March of 2017 at Kalobo Block Forest, Tanjung Peropa Wildlife Reserve (TPWR). Habitat characteristics were identified using vegetation analysis and population was estimated by concentration count method. The highest Important Value Index of trees were Pangium edule, Artocarpus elastica, and Meliostoma nitida which were Macaca ochreata’s food plants. There were 33 species of 17 families of Macaca’s food plants on the study site. Macaca ochreata were found in trees with stratum B and stratum C. A total of 4 groups of Macaca ochreata encountered consisting 56 individuals. Population density of Macaca ochreata was 22,4 individu/km2.

Bear cuscus (Ailurops ursinus) which is vulnerable in the IUCN Redlist, is one of the endemic protected animal that lives in the lowland forests of Sulawesi. This research aimed to identify habitat characteristics, diet, and daily activities of bear cuscus in Tanjung Peropa Wildlife Reserve, Southeast Sulawesi. This research was carried out from February to March 2017. Habitat characteristics were identified using vegetation analysis, diet were identified using direct and non-direct observation, and daily activities were identified using ad-libitum sampling. The highest important value index of tree at the Mobula path and Mata Air path were Pisonia umbellifera (28.33 %) and Chisocheton ceramicus (44.72 %), respectively. The vegetation species diversity was high and the vegetation species evenness was distributed. A total of 80 species of plants were recorded which are the potential diet of bear cuscus. The highest percentage parts of plants that bear cuscus consumed were shoot (36.19 %) and young leaves (36.19 %). Bear cuscus daily activities were resting (89.05 %), moving (5.83 %), foraging (2.71 %), and feeding (2.41%). Bear cuscus preferred the C stratum of vegetation for their daily activities.Keywords: bear cuscus, daily activities, diet, habitat characteristics, Sulawesi

This study aimed to determine habitat characteristics, food plants, population size, and distribution of Javan langur in Leuweung Sancang Nature Reserve. This study was conducted from February to April in Leuweung Sancang Nature Reserve. Composition and structure of vegetation were determined using vegetation analysis. Population and distribution of the javan langur were identified using concentration count method. A total of 110 plant species recorded in the javan langur’s habitat. Ketapang (Terminalia catappa) was the dominant species in the study area composing 41,71% of the IVI. The Javan langur feed on at least 17 plant species. The plant parts eaten by the Javan langur included leaves, buds, shoots, flowers and fruits. A total of 19 javan langur groups were encountered along the beach forest of the nature reserve. Number of individual at each of the group varied ranging from 7 to 17 individuals. The population size was 227 individuals and the population density was 0.15 individuals per hectare. The javan langur’s age structure of adult : young : juvenile was 43 %: 27 %: 30 % indicating that the population was dominated by adult individuals and the sex ratio of male:female was 1:3.

The population of siamang in the forest around Bulu Mario Village needs attention even though it is outside the conservation area. Therefore, this study was conducted using survey methods, vegetation analysis, and concentration count. Based on the data, siamang was distributed at an elevation of 683 - 1123 m asl in forest and mixed plantations with a dominant slope of 70.02%. Furthermore, the population was 44 individuals from 15 groups with a density of 2.88 individuals/km2, and the ratio of adult males to females was 14:12. The age classes of adults and juvenile-1 dominated the age structure pyramid; hence, the population's sustainability is considered good enough. Also, the low population density of the primate is due to habitat fragmentation in several locations. The siamang uses the entire canopy space and is associated with various other primates. Both hayu ndolok (Syzygium sp.) and rubber (Hevea brasiliensis) are the tree species with the highest abundance in the forest and mixed plantations. The siamang eats more of the fruit of 51 plant species dominated by the Euphorbiaceae family and tree habitus. Therefore, the development of animal corridors is needed to reduce the impact of habitat fragmentation.

Sleeping trees are one of the important components in the siamang habitat as an arboreal primate. The purpose of this study was to analyze the characteristics and preferences of the siamang sleeping tree and the parameters that influence it. This research was conducted in the buffer zone of the Dolok Sibual-buali Nature Reserve, North Sumatra from April to May 2022. Data collection was carried out by direct observation, recording, and measurement. The characteristics of the siamang sleeping tree generally include three parameters, namely biotic, physical, and anthropogenic activity factors. There are 12 species of trees identified as siamang sleeping trees. Based on the results of PCA, obtained 6 parameters that have the most influence on the selection of siamang sleeping trees, namely activity from cultivated land, the canopy vertical length, NDVI, distance from feeding plants, distance from settlements, and slope direction. Siamang in habitats that intersect with anthropogenic activity based on the Neu index tends to prefer the location of sleeping trees with a distance of 222,9 – 268,71 m from cultivated land and 1573,5 – 1904,29 m from settlements. Key words: Characteristics, preference, sleeping tree, siamang

Tarsius fuscus is one of the conservation priority wildlife in the Bantimurung Bulusaraung National Park (Babul National Park). This study aims to analyze the population and habitat characteristics of T. fuscus as one of the considerations in the conservation management of its population and habitat. This research was carried out in July 2021 in the forest around Bentenge Village and Samaenre Village, Resort Mallawa, Babul National Park. The method used was direct observation, calculation of the number of individuals for each group, and vegetation analysis at the meeting points of T. fuscus. Based on observations, the population size of 48 individuals from 13 groups was obtained with an overall population density of 0.109 individuals/Ha. The population density in the secondary dryland forest is higher than in the scrubland. The number of juvenile and infant in both land cover were low compared to the adults. T. fuscus was found in two types of habitat, there are secondary dryland forests (SDF) and scrubland with specific ranges of physical parameters. Based on vegetation analysis, SDF was dominated by the mana-mana tree (Blumeodendron kurzii) with an important value index (IVI) of 57.72%, while shrubland was dominated by kemiri tree (Aleurites moluccana) with an IVI of 40.75%. The two land covers are dominated by the Moraceae family and jambu air seedlings (Syzygium aqueum).
