Priyo Suharsono Sulaiman and Ngurah Nyoman Wiadnyana
One of the sea turtles nesting location in Indonesia that have a positive impact for olive ridley (Lepidochelys olivacea) captivity breeding is National Park Alas Purwo (TNAP) District of Banyuwangi East Java Province. Research was done by observation, interviewsand descriptive analysis. This research includes sea turtles captivity breeding activities as conservation efforts and also reviews the conservation success rate of increasing olive ridley population. Captivity breeding process of sea turtles in TNAP are divided into five phases: lalar (search for and collect sea turtle eggs), preparation and making of semi-natural nest, eggs incubation, maintenance and also release tukik (baby of sea turtle). Sea turtles conservation efforts in TNAP showed positive impact for the olive ridley but not yet for the other three species of sea turtles (green turtle, hawksbill and leatherback). Increase trend of olive ridley numbers those nested in TNAP should be used as a success indicator of captivity breeding and conservation processes those undertaken. Conversely, the presence of green turtles populations and leatherback turtles very low and tends to decline. This condition is expected to push for increasing activity of nesting turtle’s habitat conservation in TNAP and also in the other of sea turtles nesting area.
