Pulau Bangkaru yang terletak di Taman Wisata Alam Laut Kepulauan Banyak, Kabupaten Aceh Singkil merupakan salah satu lokasi konservasi penting bagi penyu hijau (Chelonia mydas). Penyu hijau (C. mydas) merupakan salah satu spesies yang hidup di perairan Indonesia dan telah dikategorikan sebagai spesies terancam punah (Endangered) dan dilindungi. Penelitian ini bertujuan untuk menganalisis karakteristik morfometri tukik penyu hijau di Pulau Bangkaru, Taman Wisata Alam Laut Kepulauan Banyak, Kabupaten Aceh Singkil. Sebanyak 30 ekor tukik dari 9 sarang yang baru menetas diukur menggunakan metode pengukuran linear, termasuk berat badan, panjang total, panjang dan lebar karapas (straight dan curved), panjang dan lebar plastron, panjang flipper depan dan belakang, serta panjang dan lebar kepala. Hasil penelitian menunjukkan bahwa tukik penyu hijau di Pulau Bangkaru memiliki rata-rata berat badan 21,53 ± 3,54 gram, panjang total 68,82 ± 4,06 mm, panjang kepala 19,29 ± 0,78 mm, dan lebar kepala 14,22 ± 0,50 mm, pengukuran karapas metode straight carapace length (SCL) sebesar 44,19 ± 2,90 mm dan curved carapace length (CCL) sebesar 45,20 ± 4,60 mm, sedangkan lebar straight carapace width (SCW) 33,67 ± 2,68 mm dan curved carapace width (CCW) 39,30 ± 3,31 mm, panjang plastron rata-rata 35, 28 ± 2,71 mm dan lebar plastron 29,94 ± 3,11 mm, panjang flipper depan 39,03 ± 3,33 mm, sedangkan flipper belakang 24,33 ± 2,17 mm. Kesimpulannya adalah karakteristik morfometri tukik penyu hijau di Pulau Bangkaru lebih besar dibandingkan dengan tukik penyu hijau di beberapa wilayah lain, hal ini dapat dipengaruhi oleh genetik, nutrisi induk, karakteristik awal telur, suhu dan kelembaban sarang.

Bangkaru Island, which is located in the Banyak Island Marine Nature Park, Aceh Singkil Regency, is one of the important conservation locations for green turtles (Chelonia mydas). Green turtle (C. mydas) is one of the species that lives in Indonesian waters and has been categorized as an endangered and protected species. This study aims to analyze the morphometric characteristics of green turtle hatchlings in the Banyak Island Marine Nature Park, Aceh Singkil Regency. A total of 30 hatchlings from 9 newly hatched nests were measured using linear measurement methods, including weight, total length, length and width of carapaces (straight and curved), length and width of plastrons, length of front and hind flippers, and length and width of heads. The results showed that the green turtle hatchlings on Bangkaru Island had an average weight of 21.53 ± 3.54 grams, a total length of 68.82 ± 4.06 mm, a head length of 19.29 ± 0.78 mm, and a head width of 14.22 ± 0.50 mm, the measurement of the straight carapace length (SCL) method was 44.19 ± 2.90 mm and the curved carapace length (CCL) was 45.20 ± 4.60 mm, while the straight carapace width (SCW) was 33.67 ± 2.68 mm and curved carapace width (CCW) 39.30 ± 3.31 mm, average plastron length 35.28 ± 2.71 mm and plastron width 29.94 ± 3.11 mm, front flipper length 39.03 ± 3.33 mm, while hind flipper 24.33 ± 2.17 mm. The conclusion is that the morphometric characteristics of green turtle hatchlings on Bangkaru Island are greater than those of green turtle hatchlings in some other regions, this can be influenced by genetics, broodstock nutrition, characteristics of egg, temperature and nest humidity.
