Analisis Tingkat Keberhasilan Penetasan Penyu yang Mendarat di Pulau Pandan Kawasan Konservasi Pulau Pieh dan Laut Sekitarnya di Provinsi Sumatera Barat

Abstract

Turtles have experienced a decline in population in recent times, and some sarangecies are threatened with extinction. In nature, newly hatched turtles face the threat of death from animals such as crabs, birds, and other reptiles such as monitor lizards. The greatest threat to turtles in Indonesia, as well as throughout the world, is humans. The capture of turtles for their eggs, meat, skin, and shells has reduced the turtle population. According to the IUCN, all turtles are listed in Appendix I of CITES (Convention on International Trade of Endangered Sarangecies). This convention prohibits all international trade in all products derived from turtles, be it eggs, meat, or shells. This study aims to determine the types and hatching rates of turtles and the factors that influence turtle hatching on Pandan Island, the Pieh Island conservation area and the surrounding seas of West Sumatra Province. This study was conducted in March - May 2024. The method used is the quantitative descriptive method with data collection carried out through direct observation to Pandan Island. The results of this study showed that there were 8 nests for 7 consecutive days with the types of turtles that landed were Green Turtles (Chelonia mydas) and Hawksbill Turtles (Eretmohelys imbriata) with a total of 727 eggs and 558 hatchlings successfully hatched with a hatching percentage of 76%. The factors that influence hatching are temperature, depth and diameter of the nest, beach slope, substrate and distance of the tide to the nest. Keywords: turtles, hatching rate, beach slope, nest characteristics.
