Tarsier an endemic primate species to the Indonesian island of Sulawesi. It is important to find information on the type of habitat, use of nesting trees, natural food consumed and distribution of tarsier in Central Sulawesi and Gorontalo. The study was implemented from June to August 2009 at five locations. Data collected consisted of habitat, nests or sleeping trees, type of vegetation, and natural food sources of tarsier. Observations of tarsiers activities were started at 04.00-07.00 cont Walberto Sinaga; Wirdateti .; Entang Iskandar; Joko Pamungkas

Tarsier an endemic primate species to the Indonesian island of Sulawesi. It is important to find information on the type of habitat, use of nesting trees, natural food consumed and distribution of tarsier in Central Sulawesi and Gorontalo. The study was implemented from June to August 2009 at five locations. Data collected consisted of habitat, nests or sleeping trees, type of vegetation, and natural food sources of tarsier. Observations of tarsiers activities were started at 04.00-07.00 continued from 07.30-10.00 and at 16.00, every day for a period of three months. Distribution of tarsier was estimated by capturing the tarsier using a net of six, nine and 12 meters. This study showed that tarsier inhabits secondary forests, and crop fields belonging to local inhabitants. Vegetation used as sleeping trees or nests were bamboo (Bambuseae sp.), beringin (Ficus sp.), alang-alang (Imperata cylindrica), waru (Hibiscus tiliaceus), enau (Arenga pinnata), and liana (Liana sp.). In addition, tarsier also nested in stony crevices, holes in the ground wood. The distribution of tarsier encompases secondary forest, estates, agricultural land, fields, and brushes. Natural food consumed by tarsier were insects 81.2%, reptiles 12.5% and young birds 1.3%. Mature tarsier consumed 12.76 g/individual/day of edible dry matter or about 12% by body weight and used 69.09 kkal/kg of energy. These numbers are considered sufficient to satisfy their needs for reproduction.Key words: Tarsius sp., habitat, feed, Central Sulawesi, Gorontalo.

Abstrak. Sebagai salah satu upaya konservasi, Pusat Studi Satwa Primata, Institut Pertanian Bogor (PSSP IPB) menangkarkan kukang (Nyticebus coucang) di luar habitat aslinya (eks-situ). Penelitian ini bertujuan untuk mendapatkan data konsumsi pakan asal hewan pada kukang dewasa selama satu tahun di Penangkaran PSSP IPB. Hewan yang diamati berada dalam enam kandang dengan ukuran yang sama, serta umur yang hampir seragam, masing-masing kandang berisi 2 atau 1 ekor kukang dewasa dengan jumlah keseluruhan sepuluh ekor. kukang berasal dari Pulau Sumatera, dan sudah beradaptasi di penangkaran selama tiga tahun. Jenis pakan yang diberikan berasal hewan, berupa jangkrik (Gryllus mitratus), ulat hongkong (Tenebrio molitor), ulat sutra (Bombyx mori), cicak (Cosymbotus platyurus) dan kadal rumput (Takydromus sexlineatus). Penelitian perilaku makan kukang dilakukan dengan menggunakan metode One Zero Sampling. Komposisi gizi pakan percobaan dianalisis dengan metode proksimat. Hasil penelitian menunjukkan persentase rerata kesukaan makan jenis hewan pada semua kukang, dari yang paling disukai hingga yang kurang disukai (rendah) adalah ulat sutra (Bombyx mori) dengan nilai (100%), jangkrik (91,6%), cicak (60%), kadal rumput (59%), dan pakan asal hewan yang kurang disukai adalah ulat hongkong (2,2%). Total konsumsi bahan kering pakan serangga sebanyak 284,11 g/kandang/hari atau sekitar 84,94% dan energi sebanyak 5626,79 kkal/kg.Abstract. As one of the conservation efforts, the Primate Research Center (PRC) of Bogor Agricultural University has been developing ex-situ captive breeding of coucangs (Nyticebus coucang) since 2005. This study aims to obtain data on the consumption of feed of animal origin by adults coucang during one year at PRC breeding facility. Animals were housed in six cages of the same size, while age was almost similiar. Each cage consists of 2 or 1 coucang with a total of ten animals. The animals originated from the island of Sumatra, and were adapted to captivity for three years. The type of feeds of animal origin were crickets (Gryllus mitratus), caterpillars (Tenebrio Molitor), silkworms (Bombyx mori), lizards (Cosymbotus platyurus) and grass lizards (Takydromus sexlineatus). Feeding behavior was carried out by using One Zero Sampling method. Nutritional composition of the experimental feeds were analyzed by proximate method. The results showed the average percentage of favorite by the coucang from most preferred to least preferred (low) were silkworms (Bombyx mori) with a value of (100%), crickets (91.6%), lizards (60%), grass lizards (59%), while feeds of animal origin which were less favored were hongkong worms (2,2%). Total consumption of dry feed of all insects given, amounted to 284.11 g/cage/day or approximately 84.94% with a high energy level of 5626.79 kcal/kg.Key words: feed consumption, animal origin, N.coucang, captive breeding, nutrient

The West Java black langur (Trachypithecus mauritius) is an Indonesian endemic primate found on the island of Java. Status and Conservation of the species is classified as Vulnerable based on the IUCN Red List and is listed in Appendix 2 of CITES. The West Javan langurs have been protected by Indonesian law since 1999. Under the decree of the Minister of Environment and Forestry Number. P.106/MENLHK/SETJEN/KUM.1/12/2018. The study aimed to examine population the population of the species and to determine its home range the forested area of Taman Safari Indonesia Bogor. This research was carried out from January to September 2021. Method The data collection used was a combination of methods concentrated Concentration Count using the observation method directly in the field. Analyze population distribution patterns using Nearest Neighbors, while the population distribution was analyzed using the area of the outermost point of encounter. The results showed that there were two groups of the West Java black langur existed in the area. The first group was around the location of the two houses, the panda palace, and the Jaksa waterfall 32 individuals and the second group was consisted of 15 individuals. Based on the survey, it was estimated that with an population density of T. mauritius in the area was 0.18 individuals/km² while the group density was 0.008 group/km². Group I was known to have a home range area of 17 ha while Group II had larger home range with 25 ha. The West Java black langur in this area were found to inhabit the upper parts of the forest at the altitude of 1000 to 1550 m above sea level. Population distribution patterns classified as clustered in all West Java black langur groups. The distribution of the West Java black langur population in TSI Bogor covers 58% of the total area.

Taman Safari Indonesia Bogor is a buffer zone for the Taman Nasional Gunung Gede Pangrango conservation forest area and is one of the habitats for the Javan surili langurs, but there is no research data on wild Javan surili langur populations. The object of research is to find out how many populations of Javan surili langurs are in the TSI Bogor forest area. The research method used the line transect method by collecting data on the number of individuals, the number of groups, the sex ratio, and the age structure. The research was conducted in four observation areas with varying lengths, observations were made at (06.00 - 17.00 WIB), and four repetitions were carried out on each observation path, the results showed that there were 16 Javan surili langurs individuals divided into one group, and the estimated population density was 0.06 individual/ha. The sex diversity of male and female surili langurs in the TSI Bogor forest area is 1:6 where the female Javan surili langurs are more than the male Javan surili langurs and for the age structure the largest Javan surili langurs are in the adult age class with a percentage of 43.75%, juvenile 31.25%, and the percentage of infant is 25%.
