Abstract

The population of olive ridley turtle (Lepidochelys olivacea) are currently thretened with extinction, among the contributing factors is the failure of turtle eggs to hatch. The condition can be caused by the presence of bacterial contamination, especially group Enterobacteriaceae. The purpose of this research was to isolate the group of Enterobacteriaceae bacteria from olive ridley turtle. The sample used were shells from olive ridley turtle eggs comes from natural captivity in Lhok Pante Tibang Beach, Banda Aceh. The research parameters included the number of isolates, macroscopic morphology (shape, edge, elevation, and color of isolates), cell morphology (Gram staining and cell shape), and biochemical tests. Isolation method using spread plate and quadrant method. The isolation results obtained five isolates which had varying macroscopic morphology. The five isolates were Gram negative and formed such as trunk. Identification results found that there were three genus from Enterobacteriaceae videlicet two isolates were Enterobacter, two isolates as Shigella and the other were Klebsiella.

Abstract

Penyu adalah makhluk yang menggantungkan siklus hidupnya pada sarang peneluran yang memiliki suhu inkubasi yang bervariasi. Penelitian ini dilaksanakan pada Desember 2022 sampai bulan April 2023 di kawasan pantai Kecamatan Panga, kecamatan tersebut terdiri dari 3 desa yaitu, desa Keude Panga, Kuta Tuha dan Alue Piet. Penelitian ini fokus pada suhu inkubasi, kondisi sarang, dan faktor-faktor lingkungan yang mempengaruhi penetasan telur penyu di pesisir Kecamatan Panga seperti lebar pantai, kemiringan pantai, tekstur sedimen dan pH pasir. Suhu inkubasi penetasan telur penyu berkisar 30,55℃ hingga 31,83℃. Tingkat keberhasilan penetasan telur penyu berkisar 0% hingga 80%. Nilai kemiringan pantai berkisar 1,8° hingga 4,2°. Tekstur sedimen disetiap pantai didominasi oleh pasir yang berada pada nilai diatas 80%. Hasil analisis pH di kawasan tersebut berkisar 8,4 hingga 9,4.
