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.

As one of the very rare and critically endangered species, Javan rhinoceros currently has a population of around 40-50 heads and can only be found in Ujung Kulon National Park. However, these numbers are still questionable due to the lack of description provided by the existing methods in estimating the entire population of Javan rhinoceros in the Ujung Kulon peninsula. The Javan rhinoceros timid nature, high alertness, and tendency to avoid direct contact with human and other wildlife are the factors that complicate the estimation of population. These factors make the Javan rhinoceros difficult to find and to track. One method that can be used is the video trap data analysis method. The objective of this research was to obtain information on the time and duration of Javan rhinoceros wallowing activities, the patterns and mechanisms of Javan rhinoceros wallowing activities, and the types of activity of Javan rhinoceros during wallowing. Keywords : Javan rhinoceros, wallowing behavior

Almost all Indonesia’s national parks (NP) faced the challenge of managing their finances. One innovative way of raising additional funds was the rate of incoming visitors. Determination of entrance fee for national park was currently based on regional allocation of market system not on conditions and potentials of the respective national parks. Fees for incoming visitors were uniform for all national parks within a single regional allocation market. Such uniformity had resulted in relatively low fees for some NP and relatively high for others. As a price, visitors entrance fee required to be assessed not only from the user side but also from the manager’s, especially in national parks with high potential number of visitors, such as Gunung Merapi (GMNP) with 165,851 visitors annually. The objectives of this study were to (1) identify the factors that affect the amount of entrance fee, (2) determine entrance fee based on GMNP annual management expenses using main cost approach, (3) determine entrance fee based on visitors using travel cost method and (4) determine entrance fee based on annual expenses for GMNP management and visitors. Results of the analysis showed that factors affecting GMNP entrance fee were: (1) based on annual management expenses were operational cost and total number of visitors, (2) based on visitors were travel cost, tourism attractions and total number of visitors per group, and (3) based on annual GMNP management expenses and visitors, were travel cost, tourism attractions, number of visitors per group, operational cost and total number of visitors. Keywords : eexpense, entrance fee, scenario, visitors
