The parameters measured covered the diameter of the egg, the egg weight, the length of the embryo, the weight of the embryo, temperature, rate of water sand and the intensity of the light. The research\u27s data result were analyzed by Analysis of Variant (ANOVA), and then followed by a Tukey test. The results of the research showed that there are olive ridley turtle\u27s eggs which were fertilized and not fertilized by doing the shade treatment and incubation period. Environmental factor that were measured is the average value of the rate of water in shaded nest 3 ± 1 % no shade 4 ± 3, the temperature of the air was 29,66 ± 4,24 oC, the temperature of the shaded soil 30,71 ± 6,45 oC, with no shade 33,52 ± 2,20 oC, the intensity of the light at 06.00 WIB with shade 90 ± 85,24 no shade 74,2 ± 44, the intensity of the light at 14.00 WIB with no shade 32385,71 ± 2542,59, no shade 64371,43 ± 34055,28.
