Abstrak – Penyu sisik (Eretmochelysimbricata) merupakan salah satu jenis penyu yang hidup di perairan Indonesia. Populasi penyu sisik saat ini terus mengalami penurunan. Salah satu faktor penyebabnya adalah keberadaan mikroba pencemar pada telur penyu. Tujuan dari penelitian ini adalah mengetahui cemaran mikroba pada telur penyu sisik di Pulau Kelapa Dua. Analisis secara mikrobiologi meliputi total bakteri, jamur, coliform, Enterobacter, dan Salmonella-Shigella dilakukan terhadap sampel telur segar dan telur gagal menetas. Hasil analisis menunjukkan bahwa semua sampel tercemar mikroba yang mempengaruhi daya tetas telur. Sampel cangkang telur segar memiliki total bakteri 9,60x105 CFU/butir,  jamur 2,35x105 propagul/butir, coliform 3,96x105 CFU/butir, Enterobacter 3,02x105 CFU/butir dan Salmonella-Shigella 1,68x105 CFU/butir, sedangkan hasil analisis dari sampel isi telur segar diperoleh total bakteri 1,60x104CFU/ml, jamur 3,00x102propagul/ml, coliform 2,00x105CFU/ml, Enterobacter 1,20x105CFU/ml dan Salmonella-Shigella 1,46x105CFU/ml. Hasil analisis dari sampel cangkang telur gagal menetas diperoleh total bakteri 7,20x106CFU/butir, jamur 1,92x105 propagul/butir, coliform 4,08x105 CFU/butir, Enterobacter 2,59x105CFU/butir dan Salmonella-Shigella 3,31x105CFU/butir, sedangkan hasil analisis dari sampel isi telur gagal menetas diperoleh total bakteri 1,00x108CFU/ml, jamur 3,50x105propagul/ml, coliform 5,00x103CFU/ml, Enterobacter 4,00x103CFU/ml dan Salmonella-Shigella 3,00x103CFU/ml.
Kata Kunci - Penyu sisik, telur, Pulau Kelapa Dua, cemaran mikroba.

Abstract - Hawksbill (Eretmochelysimbricata) is one of the turtle species that live in Indonesian waters. The current population of hawksbill continues to decline. One of the contributing factors is the presence of contaminant microbes in turtle eggs. The purpose of this research is to know microbial contamination on hawksbill eggs in Kelapa Dua Island. Microbiological analyzes included total bacteria, fungi, coliform, Enterobacter, and Salmonella-Shigella were performed on fresh egg samples and eggs failed to hatch. The results showed that all samples were contaminated with microbes affecting the hatchability of the eggs. Fresh eggshell samples had total bacteria of 9.60x105 CFU/grains, 2.35x105 fungus propagules/grains, coliform 3.96x105 CFU/grains, Enterobacter 3.02x105 CFU/grains and Salmonella-Shigella 1.68x105 CFU/grains, while yield analysis of fresh egg contents samples obtained total bacteria 1.60x104 CFU/ml, mushrooms 3,00x102 propagules/ml, coliform 2.00x105 CFU/ml, Enterobacter 1,20x105 CFU/ml and Salmonella-Shigella 1,46x105 CFU/ml. Results of analysis of eggshell samples failed to hatch obtained total bacteria 7.20x106 CFU/grains, 1.92x105 fungi propagules/grains, coliform 4.08x105 CFU/grains, Enterobacter 2.59x105 CFU/grains and Salmonella-Shigella 3.31x105 CFU/while the results of the analysis of the sample of egg contents failed to hatch obtained total bacteria 1.00x108 CFU/ml, mushrooms 3,50x105 propagules/ml, coliform 5.00x103 CFU/ml, Enterobacter 4,00x103 CFU/ml and Salmonella-Shigella 3, 00x103 CFU/ml.
