Abstract

Zoos have four main roles namely conservation, research, education and recreation. Whether the existence of the zoo has succeeded in increasing or at least influencing people's perceptions of animal conservation should be investigated further. The research aimed to assess the image of the zoos and perception of the visitors about orangutan conservation. This study applied the questionnaire and methods to Indonesia zoo's, and examines the effect of the zoo at changing visitor's conservation awareness. The result showed that there were no significant difference acros the sites and between arrival dan departures. This could be caused by many reasons, for example the short visit time, minimal information obtained during the visit or the background of the visitors themselves.

Abstract

Between 1;ebruary 1488 and June 1941, 478 long-tailed macaques (58 males, 420 females) were releasedonto 'Tinjil Island to estahlisli a natural habitat breeding facility. The monkeys were released on 10 differentoccasions over the three years period and did not represent established social groups at the time of release. Approxirnalely 33% of the entire breeder populalion (28 males and 130 females) has been identified by tattoo. Because each monkey received a chest tattoo before released onto the island, it has been possible to reconstruct and tract social group formation by matching an individual's tattoo with its date of release. Assesment of the tattoo data From five of the groups identified on the island indicates that the social groups are not composed of animals from a single release group, hut rather consist of animals from several release groups. Animals from all10 release groups are represented among the five social groups. Membership in the five groups has remainedrelatively stahle during the past four years olohservation (1990-1993) with minimal exchange of group members.

Abstract

The most southern Sumatran orangutan natural habitat is located in Batang Toru Forest Block. This study aims to determine  use of vertical space and the daily range of Sumatran orangutans in Batang Toru Forest. At least 17 different individual have been identified, but only 7 individual have been habituated. This study aims to determine use of vertical space and the daily range of Sumatran orangutans in Batang Toru Forest, begun by examining 7 habituated individu. Data vertical space was collected by focal animal sampling and ad libitum by following the individual orangutan from nest in the morning until next nest in the dusk , with each 2 minute recording intervals. Orangutans used the vertical level on 16-25 m where the fruits were abundant or at the position 72,00-82,14% from the groumd. The mean day range is 760,73-1089,28 m. There is not difference between daily range of the orangutan adult male, adult female and adolescent ( F = 0.119 ; p value = 0.94 ; α = 0.05). Keywords: daily range, Sumatran orangutan, vertical space

Abstract

Javan gibbon is endemic and endangered primate of Java. The research aims to map home ranges and territories of three habituated javan gibbons (Goup A, B and S) in Gunung Halimun-Salak National Park from March to July 2015. This finding will support the conservation management for javan gibbon. The mapping of those areas was determined by following the groups for 541 hours and analyzed the data using minimum convex polygon. The home range average of the three groups was 33,41 ha (Group A = 23,7 ha; B = 43,8 ha; and S = 32,7 ha). The largest home range had the lowest food tree densities (50 ind/ha). The average of territory was 0,57 ha (Group A = 0,4 ha; B = 0,8 ha; and S = 0,4 ha). The territory areas had food tree densities in higher (116,7 ind/ha) compare to the home ranges (76,7 ind/ha). The large territory area had low food tree densities (90 ind/ha), otherwise the small territory area had high food densities (Group A 160 ind/ha; Group S 110 ind/ha).Keywords: habitat, home range, javan gibbon, territory

Abstract

Kloss’s gibbon (Hylobates klossii) is endemic primate to the Mentawai Islands of the West Sumatra, and currently categorized as Endangered according to IUCN Red List in 2008. The latest population information on Siberut Island is incomplete and not comprehensive yet. Assessment of population was used as a base in determining the conservation strategies. This study aimed to identify the Kloss’s gibbon population that includes population distribution, individual and group density, group size, and group composition. This research was conducted in Bojakan Resort, Siberut National Park, Siberut Island, Mentawai Islands, West Sumatra. Surveys for primates were carried out between November 2018 and Januari 2019. Following previous primate surveys and general recommendations, this study used line transect sampling. Total Kloss’s gibbon individuals found were 77 individuals with 25 groups. Average individual density was 12,8 individuals km2, group density was 4,2 groups km2, and group size was 3,08 individuals group. Kloss’s gibbon populations was affected by disruption of human activity. Kloss’s gibbon density in Bojakan Resort was higher compared to previous studies on Siberut Island. The percentage of Kloss’s gibbon groups that have a group size of more than two individuals was higher than the group of two individuals, indicating that forests in Bojakan Resort was abble to support the Kloss’s gibbon population. There were many groups that have at least one or more offspring, a good sign that regeneration progress was still ongoing. Monitoring and patrolling by National Park is needed to ensure the existence of the Kloss’s gibbon population in that area. Keywords: endemic primate, kloss’s gibbon, line transect sampling, monogamy

Abstract

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.

Data collections of feeding behaviours were performed using focal animal sampling method. While based in 336 hours of observation within 6 months, orangutans spent 53,18% of the time on feeding, 17,27% on resting, and 14,79% on traveling. The daily activity pattern was distributed bimodally with peaks at about 08.00 and 14.00. More feedig took place in the morning (08.00-10.30) and in the afternoon (13.30-16.00), while midday was reserved for resting. Orangutans were fed 96,90% of the feeding time on foods from the Schmutzer Primate Centre, and 3,10% on other foods available in the exhibition cages. Three species of plants were consumed frequently; figs (Ficus benjamina) (0,48%), rumput gajah (Pannisetum purpureum) (0,24%) and velvet tamarind (Dialium indicum) (0,21%), respectively. In addition, orangutans sometimes ate soil, feces, and insects. Key words: Pongo pygmaeus, feeding behavior, Schmutzer Primate Centre

Abstract

The Javan Gibbon is a primate species endemic to Java, Indonesia and considered as an endangered species (IUCN 2008). The Primate Research Center of Bogor Agricultural University (PRC-IPB) in cooperation with Taman Safari Indonesia have established an ex situ breeding facility for the Javan Gibbon to support conservation program. The breeding was started in 2003, and up to recently, the pair of Javan Gibbons ( 15 and 7 years old) has had three offspring, and still occupy one common cage. Assessment of the Javan Gibbon’s behavior in captivity especially to the family with five individuals was conducted using focal animal sampling to provide basic behavioral data.  Moving was the greatest frequency (45.70%) of each individual compared to other behaviors, while resting was the greatest duration that occurred to the parents, and playing was the greatest duration (18.02%) to the offspring respectively.    Keywords : behavior, javan gibbon, endangered, captive breeding

Abstract

This research was conducted in Gunung Gede Pangrango National Park and aimed to study javan gibbon population  and analyzing problems affecting the existence of the species. The total number of individuals were founded in this research were 42 individuals of 13 groups. The densities of javan gibbon at core zone were 7.14 individuals/km2 and 2.30 groups/km2, whereas at utilization zone were 5.69 individuals/km2 and 1.54 groups/km2. Estimated total individual density were 6.43 individu/km2 whereas group density were 1.93 groups/km2. The estimation of javan gibbon in Gunung Gede Pangrango National Park were 347 individuals in 105 groups. Several problems occured to the habitat and the population of javan gibbon in Gunung Gede Pangrango National Park were: (1) illegal logging; (2) agricultural lan dclearing; (3) tourists and other human activities; (4) illegal hunting; (5) firewoods gathering; (6) non-wood forest product extraction. There were three recommendations to ensure the conservation of javan gibbons in Gunung Gede Pangrango National Park: (1) enhancing the management of Gunung Gede Pangrango National Park areas; (2) managing the activities of local people; and (3) managing tourist program of Gunung Gede Pangrango National Park. Keywords: javan gibbon, population, National Park
