Abstract

ABSTRAK Niken Purnamasari. Evaluasi Metode Inkubasi Ex Situ Terhadap Kualitas Neonatal Penyu Sisik di Pulau Harapan Taman Nasional Kepulauan Seribu. Skripsi, Program Studi Biologi, Fakultas Matematika dan Ilmu Pengetahuan Alam, Universitas Negeri Jakarta. Penyu sisik merupakan jenis penyu yang tersebar di wilayah Indonesia, salah satunya di Kepulauan Seribu. Penelitian ini bertujuan untuk mengetahui pengaruh metode inkubasi terhadap keberhasilan penetasan telur, perbedaan suhu, dan pengaruh metode inkubasi terhadap kualitas tukik penyu sisik. Penelitian ini menggunakan kuasi eksperimen untuk membedakan keberhasilan penetasan dan kualitas neonatal penyu sisik antara inkubasi semi alami dan buatan (ember polystyren). Parameter yang diukur adalah keberhasilan penetasan, suhu sarang, morfometri, lokomosi (kecepatan membalikkan tubuh dan kecepatan berjalan) penyu sisik. Hasil menunjukan persentase keberhasilan penetasan cenderung lebih tinggi di inkubasi buatan (32%) dibandingkan inkubasi semi alami (11%), adanya perbedaan yang signifikan antara metode inkubasi dalam parameter keberhasilan penetasan memiliki nilai (asymp.sig) 0,000 < 0.05. Suhu inkubasi semi alami memiliki suhu lebih rendah (29℃) dibandingkan inkubasi buatan (31℃). Tukik yang di inkubasi buatan memiliki ukuran morfometrik lebih besar yaitu pada panjang karapas (3,86 cm ± 0,042), lebar karapas (3,20 cm ± 0,073), panjang tubuh (6,58 cm ± 0,065), berat tubuh (11,25 gram ± 0,198), dibandingkan dengan inkubasi semi alami lebih kecil pada panjang karapas (3,76 cm ± 0,037), lebar karapas (2,83 cm ± 0,111), panjang tubuh (6,30 cm ± 0,047), berat tubuh (10.60 gram ± 0,141). Kecepatan membalikan tubuh secara signifikan lebih cepat di inkubasi buatan (5,3 detik ± 2,091) di bandingkan dengan inkubasi semi alami (39,20 detik ± 2,732), untuk kecepatan berjalan lebih cepat pada inkubasi buatan (1,13 menit ± 0,085) dibandingkan dengan inkubasi semi alami (2,39 menit ± 0,246). kata kunci: Penetasan, suhu , morfometrik, lokomosi, penyu sisik. ABSTRACT Niken Purnamasari. Evaluation of Ex Situ Incubation Method on the Quality of Neonatal Hawksbill Turtles in Harapan Island, Seribu Islands National Park. Thesis, Biology Study Program, Faculty of Mathematics and Natural Sciences, Jakarta State University. Hawksbill turtles are a type of turtle that is spread throughout Indonesia, one of which is in the Seribu Islands. This study aimed to determine the effect of incubation methods on the success of egg hatching, temperature differences, and the effect of incubation methods on the quality of hawksbill turtle hatchlings. This study used a quasi-experiment to differentiate the success of hatching and the quality of hawksbill turtle neonatal between semi-natural and artificial incubation (polystyrene buckets). The parameters measured were hatching success, nest temperature, morphometry, locomotion (body turning speed and walking speed) of hawksbill turtles. The results showed that the percentage of hatching success tended to be higher in artificial incubation (32%) compared to semi-natural incubation (11%), there was a significant difference between incubation methods in the parameters of hatching success having a value (asymp.sig) 0.000 <0.05. The temperature of semi-natural incubation had a lower temperature (29℃) than artificial incubation (31℃). Hatchlings that were artificially incubated had larger morphometric dimensions, namely carapace length (3.86 cm ± 0.042), carapace width (3.20 cm ± 0.073), body length (6.58 cm ± 0.065), body weight (11.25 grams ± 0.198), compared to semi-natural incubation which was smaller in carapace length (3.76 cm ± 0.037), carapace width (2.83 cm ± 0.111), body length (6.30 cm ± 0.047), body weight (10.60 grams ± 0.141). The body turning speed was significantly faster in artificial incubation (5.3 seconds ± 2.091) compared to semi-natural incubation (39.20 seconds ± 2.732), while walking speed was faster in artificial incubation (1.13 minutes ± 0.085) compared to semi-natural incubation (2.39 minutes ± 0.246). Keywords: Hatching, temperature, morphometrics, locomotion, hawksbill turtles.
