Keberhasilan Penetasan Telur Penyu Sisik (Eretmochelys imbricata) dalam Sarang Semi-Alami di Pulau Harapan, Kepulauan Seribu

Abstract

Penyu sisik (Eretmochelys imbricata) merupakan jenis penyu yang tersebar di wilayah Indonesia, salah satunya di Kepulauan Seribu. Penelitian ini bertujuan menganalisis teknik penetasan telur penyu sisik yang dapat mempersingkat masa inkubasi dan meningkatkan keberhasilan penetasan telur penyu sisik di kawasan konservasi penyu Pulau Harapan. Penelitian ini menggunakan Rancangan Acak Lengkap (RAL) dengan tiga perlakuan, yaitu ember tanam dalam pasir, ember di permukaan pasir, dan pasir tanpa ember. Parameter yang diukur adalah suhu, kelembaban, substrat sarang, masa inkubasi, dan Jumlah telur yang menetas dan gagal menetas. Hasil menunjukkan suhu rata-rata di semua perlakuan memiliki rentang nilai 30,12 - 30,98℃. Kelembaban rata-rata pada rentang nilai 84,67 - 86,38%. Rata-rata masa inkubasi paling rendah terjadi pada perlakuan ember tanam dalam pasir yaitu selama 48 hari. Keberhasilan penetasan telur tertinggi terdapat pada perlakuan ember tanam dalam pasir, yaitu 70%. persentase keberhasilan penetasan cenderung lebih tinggi dengan masa inkubasi paling singkat pada teknik dengan ember ditanam dalam pasir. Namun demikian, perlakuan teknik penetasan memiliki pengaruh yang tidak signifikan terhadap lama masa inkubasi dan keberhasilan penetasan telur penyu sisik.

Hawksbill turtle (Eretmochelys imbricata) is a type of sea turtle that is spread across Indonesia coral reef, one of the area is the Thousand Islands. This study aims to analyze hawksbill turtle egg hatching techniques that can shorten the incubation period and increase the hatching success of hawksbill turtle eggs in the Harapan Island turtle conservation area. This study used a completely randomized design (CRD) with three treatments. Parameters measured were temperature, humidity, nest substrate, incubation period, and number of eggs hatched and failed to hatch. The results showed that the average temperature in all treatments had a value range of 30.12 - 30.98℃. Average humidity in the value range of 84.67 - 86.38%. The lowest average incubation period occurred in the treatment of planting buckets in sand, which was 48 days. The highest egg hatching success was found in the treatment of planting buckets in sand, which was 70%. The percentage of hatching success tends to be higher with the shortest incubation period in the technique with buckets planted in sand. However, the treatment of hatching techniques had a non-significant effect on the length of the incubation period and the hatching success of hawksbill turtle eggs. However, the hatching technique treatment had a non-significant effect on the length of the incubation period and the success of hatching hawksbill turtle eggs.
