Sukamade Beach is a stopover for four of the 7 types of sea turtles in the world. Green turtles (Chelonia mydas), hawksbill turtles (Eretmochelys imbricata), slengkrah turtles (Lepidochelsy Olivacea), and leatherback turtles (Dermochelys coriacea) come to the Meru Betiri coast to lay their eggs. The threats to turtle eggs are numerous, so for the safety of the new generation of ancient reptiles, the eggs will be relocated to a semi-natural hatchery.

The semi-natural hatching method is carried out with the same treatment and conditions (nest depth and egg position) as when the eggs are in their natural habitat. The success rate of this method reaches 80% with a hatching period of between 55 to 60 days. Embryo growth is greatly influenced by temperature. Embryos will grow optimally at a temperature range of between 22 – 24 C and will die if outside this temperature range. Environmental conditions that greatly affect embryo growth until hatching include: sand temperature, water content in the sand, and oxygen levels.
