Abstract

Maleo population is decreasing due to the decline in suitable breeding site. The establishment of a maleo sanctuary in Hungayono aims to increase maleo population by protecting its eggs and increasing the success rate of eggs hatched. This study aims to analyze the characteristics of maleo nesting habitats, to describe the semi-natural maleo egg hatching management in the sanctuary, and analyze the success rate of maleo egg hatching in Hungayono. The results showed that the Maleo nesting sites are clean of bushes and shrubs, but there was still shades from trees or bamboo. The nesting sites are close to rivers and geothermal sources with mixed soil structure. The natural egg burrows has an average depth of 92.8 cm, width of 82.7 cm, temperature of 32.5 oC, and humidity of 90%. Hungayono has seven hatcheries that utilized geothermal heat to hatch Maleo egg semi-naturally. The burrows size in the hatcheries were made according to the size of Maleo eggs, with an average depth of 32 cm and width of 10 cm, the average temperature is 32.5 oC and humidity is 90.8%. The incubation period for the semi-natural hatcheries is 60-80 days. Maleo egg hatching success rate reached 60.18% in which is medium category.

Abstract

The population of the Javan langur (Trachypithecus auratus) is currently decreasing, so the threat to the preservation of the Javan langur requires conservation efforts that are beneficial for conservation in nature.One of the conservation efforts is carried out ex-situ, such as the one at the research station at the Javan Langur Center. This study aims to determine the Rehabilitation management of Javan langurs at the Javan Langur Center. The method used in this research is the interview, field observation, and literaturestudy. The use of strategic factor analysis (SWOT) is carried out in the management of Javan Langur rehabilitation which includes analysis of internal factors and external factors. The first rehabilitation management, namely the development strategy at the research site, is carried out through a rehabilitation program strategy. The second utilizes and maintains good support from the government. Third, utilize experienced human resources. Fourth, increase the number of health workers who are still lacking. Fifth,improve the quality and quantity of facilities and infrastructure. Sixth, add experienced human resources. Seventh, improving the quality and quantity of facilities at the Javan Langur Center.
