Javan Langur (Trachypithecus auratus) has an important ecological role in conserving the forest as their habitat by spreading seeds of fruits of their food. They are also responsible for the pattern of the plant diversity and forest regeneration as their habitat. Unfortunately, Javan Langur has been listed on Appendix II of CITES and categorized as vulnerable by the IUCN. Pancuran 7 Baturaden on the Mount Slamet slope is one of the few Javan Langur habitats in Java. Information on the Javan Langur in this area was inadequate. Therefore this study was aimed to get information on the type of food and the feeding behavior of Javan Langur, particularly in Pancuran 7 Baturaden. This study used a survey method, and the Animal Scan sampling technique was applied. The variables observed were sex ratio, population size, eating position, eating process, feeding locations, feeding duration, including the food type of the Javan Langur. Observed data for each variable were analyzed descriptively as percentages, and the results showed the Javan Langur were eating by sitting and standing, were marking trees to feed, were using hands and mouth to eat, were eating leaves and fruit, were eating on the trees and bushes. There were nine plant species as their food variety, while Matoa fruit and leave (Pometia pinnata) were their preferred foods.

Nematode parasites generally found around the world. Research on intestinal parasitic nematodes in long-tailed monkeys (Macaca fascicularis) has been carried out in Cikakak Village, Banyumas Regency. The aims of the research was to find out the diversity and prevalence of Nematodes parasite on long tail monkey. Survey methods was used in this research with determine the eggs of the nematodes parasite on faeces of 30 adults and 30 adolescence of monkey. The results of the study found five types of intestinal parasitic nematodes classified as " Soil Transmitted Helminths " namely Strongyloides sp. Ascaris sp. Trichuris sp. Ancylostoma sp. Oeshopagustomum sp. The parasitic diversity index value (H ') indicates moderate (moderate) community stability. Parasitic nematodes in adolescent long-tailed monkeys are relatively similar to adult monkeys. The prevalence of long-tailed monkeys infected with parasitic nematodes is quite high at 40.5 ± 13.5. The prevalence of long-tailed monkeys in adolescence is higher than the prevalence of adult long-tailed monkeys, nematode infections in long-tailed monkeys in Cikakak Village are more single infections. It can be concluded that long tail monkey at Cikakak have been infected by Nematodes parasites and this result can be used to population management of long tail monkey at this area.

Javanese Gibbon (Hylobates moloch) is the endemic primate species in Indonesia. IUCN - World Concervation has given this species an endangered status. The habitat Hylobates moloch’s were found at Slamet Mountain in Central Java. The study entitled "Study of Javanese Gibbon (Hylobates moloch) Population in Slopes of Slamet Mountain, Central Java" aimed to determine the number of population in slopes of Mount Slamet. This research was conducted in the exact line these July -November 2013, the survey method with stratified sampling base on line transect method was used in this research. Transects pathway in this study used existing pathways wich the passed and cut the contour of research sites. Javanese Gibbon (Hylobates moloch) obtained along the transect was calculated and analyzed using perpendiculars distance approach (DISTANCE 5.0’s software). Analysis by DISTANCE 5.0 showed that the density of Javanese Gibbon (Hylobates moloch) at Slamet Mountain in 170 km2 area was 0.26 individual/km2, coefficient of variation was 34.88 % , lower limit of 95 % confidence interval was 0.13365 to 0.51981. Based on the analysis, total number of javanese gibbon population at Slamet Mountain was 45 individuals of the density 0.26 individuals/km2.
