Design of automatic eggs hatchery as preservation of turtle in coastal of East Java

摘要

There are 6 of 7 species of sea turtles in the world found in Indonesia. Meanwhile, the existence of sea turtles is currently experiencing a very drastic decline. This research is one of the conservation efforts to increase the number of sea turtles in several turtle conservation areas in East Java. From the experimental results, the temperature is the most influential factor in the sex determination. The development of egg incubation technology in this study has resulted in hatching results with the number of male sex dominant than female. To produce male eggs the temperature in the hatching media is between 25°C - 30°C, while the optimal temperature for hatching female eggs is >30°C. The artificial turtle egg incubator technology is designed in such a way that the conditions in the hatching chamber are close to the hatching conditions in nature with a temperature that can be set with an incandescent lamp equipped with a temperature sensor, when the high temperature the temperature sensor will work and the incandescent lamp automatically turns off. Optimum moisture conditions of about 70% water content can be regulated by the humidity sensor, when humidity is reduced, it can automatically spray water.
