Javan rhinoceros (Rhinoceros sondaicus) is one of the rarest rhinoceros that are still existing today. Their distribution is limited to only a handful of countries including Indonesia, Vietnam, and possibly in Cambodia and Laos. In Indonesia, the species is only found in Ujung Kulon National Park (UKNP). Its population is concentrated in the Ujung Kulon peninsula. Theoretically, large animals have preferences in their habitat and therefore tend to distribute uniformly or clumped. In consequence, the management of javan rhino population and habitat must consider their habitat preference. The objectives of this study were: 1) to identify dominant habitat components that determine the presence of Javan Rhinoceros in UKNP, and 2) to formulate habitat preference typology. The study was carried out in Management Section II area of UKNP, Pandeglang District, Banten Province. Method applied was direct field observation and literature review. Based on multiple linear regressions, the dominant habitat factors preferred javan rhino were soil pH (X7) and salinity (X9). The equation formulated was Y = 6.25 – 1.12 X7 + 3.88 X9. Using Neu’s method of preferential index analysis, it was revealed that Citadahan, Cibandawoh, Cikeusik and Cigenter had preferential indices greater than 1. The data shows that javan rhinoceros mostly prefer habitats located 400-600 m from the coast, and areas located 0-400 m was considered as their second preference.

Javan rhino (Rhinoceros sondaicus Desmarest 1822) of which spread is limited in Indonesia and Vietnam is the rarest species among 5 species of rhino in the world. Without appropriate and long-term well organized management action, the population of javan rhino will be in extinction. This research studies about the usage potential of javan rhino population genetics data in designing javan rhino conservation program. The application of genetics study in conservation problem is based on the population genetics theory. The population genetics is one of population biology branch which studies about the factors determining genetic composition of population and how they play role in evolution process. The genetic characteristic identification can help to give the characteristic genetic information which has function as genetic marker or gen in javan rhino management. It can also help to do translocation the javan rhino especially for breeding management effort to avoid inbreeding and to improve the heterozygosis. The analyzing result shows that the management of conservation strategy which can make javan rhino population reaches the population viable minimum number is needed urgently. Furthermore, it also shows that translocation and reintroduction to build the second population of javan rhino is also important to do. Keywords: javan rhino, population genetics, translocation, second population

Javan rhino (Rhinoceros sondaicus Desmarest 1822) is one of world's rarest endangered species (IUCN 2008). Currently, their distribution is limited to Ujung Kulon National Park (UKNP) of Indonesia. Natural disasters, disease, poaching, encroachment, and competition are threats facing Javan rhino's population, hence creating pockets of habitats outside the UKNP was necessary and should be based on scientific studies of javan rhino utilization distribution and habitat selection in UKNP as the natural habitat. The objectives of the study were to determine the utilization distribution of Javan rhino and its habitat characteristics and determine javan rhino habitat selection within UKNP. The research indicated that Javan rhinos highest use of areas comprised of swampy shrub (w = 2.197) and shrub (w = 2.012), relatively open habitat (w = 4.233), flat area (w = 1.313) and slightly sloping areas (w = 1.007), lowland (w = 1.346), close to river (w = 1.087), close to road network (w = 1.395), close to coasts/beaches (w = 1.862), close to wallowing areas (w = 3.709), and close to rumpang (w = 3.783). The results suggested that javan rhino showed selection and preferences for its habitat.

Javan rhino (Rhinoceros sondaicus) is one of the rarest species in the world so categorized as critically endangered by IUCN. Survival of the rhino in Ujung Kulon National Park is threatened by a variety of factors that could cause these extinct animals, such as: invasion langkap, competition with the bulls, and inbreeding. The strategy should be promoted in maintaining and developing population that is making a second habitat. The purpose of this research is to know the suitability level of Cikepuh Wildlife Reserves (CWR) as javan rhino’s second habitat. The method used is the field observations. Results showed that the CWR have high suitability as javan rhino’s second habitat with an area of 6886.4 ha (84.72% CWR). Cikepuh Wildlife Reserves components that have a high potential as second habitat are on aspects altitude, air temperature, humidity, water availability, and soil pH. Strategies that can be done in improving the suitability of the CWR as second habitat includ: create pools ofthe rhino, planting food plants that have a high palatability and reduce human pressure through strict enforcement, public education, standardized regular patrols, rehabilitation and enrichment of degraded area, livestock expenses , and review the MoU regarding the use of the area as a military Cikepuh SM. Keywords: Cikepuh Wildlife Reserve, habitat suitability, javan rhino, second habitat

The size and type of animal groups is affected by various ecological factors, such as vegetation and seasonal changes. Understanding of the environmental factors that influence the variation of size and type of the group is important to manage the species according to its behaviour. This study was conducted by using video trap. There were two types of barking deer group size, solitary (97%) and family unit (3%). Solitary barking deer most frequently recorded in secondary forest, while family unit in shrub vegetation. Six types of group were identified: 46% male groups; 32% female groups; 19% sub adult groups; 3% mixed adult groups; 0.003% adult and sub adult groups; and 0.001% family group. Adult and sub adult groups and family group captured most frequently in shrub, while male, female, and sub adult groups in secondary forest. Mixed adult groups captured most frequently both in shrub and secondary forest. Chi-square test indicated that both group size and group type variation were not correlated with vegetation types. Group types significantly related to the time of survey, but group size was not correlated. Keywords: Barking deer, Group type, Group size, Ujung Kulon National Park, Vegetation types.

Inventory of the rare javan rhino population keep doing continuously to know the trend of javan rhino population. However, inventory of javan rhino population hard to be done by people because javan rhino very sensitive to human presence. Inventory of javan rhino has improved by using camera trap but not every camera trap effective on capture the javan rhino. One of the problem is the location of camera trap not appropriate with javan rhino movement. Therefore, analizing correlation between characteristic of camera trap site with the success of recording javan rhino is necessary. The objective of this research is to identify the correlation between some of the characteristic of camera trap site which is estimated related to the success of recording javan rhino. The result of this research indicates that distance between camera trap with feces, footprint, human track and topography has correlation with the amount of javan rhino clip. Keywords: camera trap, javan rhino, Ujung Kulon National Park.
