One of the conservation efforts of the Lepidochelys olivacea turtle in Indonesia is by saving its eggs on the beach, hatching, rearing and releasing hatchlings into the sea. However, a lack of knowledge in management has affected many turtle eggs that do not hatch and hatchlings that die during maintenance. Breeding activities are controlled incubation and hatching of eggs in order to make L. olivacea more developed and avoid extinction. Eggs are planted at a certain depth of the nest but it is not known at what depth the eggs have good hatchability. The aim of this study was to determine the hatchability of the eggs and morphometric of the hatchlings (Lepidochelys olivacea) based on the depth of the brood nest. This research was conducted in 2016 at Muara Tembulih, West Coast of Lampung Province. The treatment was designed with a Completely Randomized Design in the form of four (4) treatment of egg incubation depth and 6 replications. The results of the study were treatment with nest depth of 40-45 cm, hatchability (70-73%) and morphometric size of the newly hatched turtle hatchlings (body weight ± 23 g; body length ± 7 cm, carapace length ± 4 cm and width carapace ± 3.52 cm) statistically, much higher than in nest depths of 35 and 50 cm.
