Identification and prevalence of soil-transmitted helminth eggs in Javan gibbon (Hylobates moloch) and Javan langur (Trachypithecus auratus) at Petungkriyono Forest, Central Java, Indonesia. Biodiversitas 23: 4501-4509. Javan gibbon (Hylobates moloch) and Javan langur (Trachypithecus auratus) are arboreal primates found at Petungkriyono Forest, Central Java, Indonesia. An increase in ecotourism activity in Petungkriyono Forest affected wildlife behavior and forest landscape along the road. Canopy connections separated by the main road is essential for both of these primates They were spotted foraging food and moved across the separated habitat using available canopy. Based on their activity and habitat along the main road, this research is conducted to identify and count the prevalance of soil-transmitted helminth eggs in their gastrointestinal through their feces. A total of 72 Javan gibbon and 46 Javan langur fecal samples were collected under 10% formalin preservation. Fecal samples were examined using the mini-FLOTAC method for Javan gibbon and the flotation method for Javan langur. The results indicate three orders, including Enoplida, Strongylida, and Rhabditida, were found and the prevalence of helminthiasis is 31.94% for Javan gibbon and 47.82% for Javan langur. Eventhough both of these primates helminthiasis prevalance is considered to be low, higher prevalance in Javan langur was caused by its behavior to be less arboreal than Javan gibbon.]]>
