Nata de coco adalah makanan yang berasal dari hasil fermentasi air kelapa dengan bantuan bakteri Acetobacter xylinum. Nata ini dapat digunakan sebagai dessert dan kaya akan serat. Pembentukan nata sangat membutuhkan nutrisi nitrogen. Hal ini perlunya mengetahui jenis sumber nitrogen dan komposisi yang tepat dalam fermentasinya. Penelitian ini bertujuan mengetahui pengaruh perbedaan sumber nirogen (urea, ZA, amonium sulfat,dan yeast ekstrak) serta mencari komposisi agar diperoleh nata dengan sifat fisik terbaik. Penelitian dilakukan dalam dua tahap yaitu mencari sumber nitrogen dan dilanjutkan mencari komposisi yang tepat. Hasil penelitian menunjukkan bahwa urea memberikan hasil terbaik dalam menghasilkan nata de coco dengan yield sebanyak 87,36 %, tebal 8,6 mm dengan komposisi sebanyak 5 gr dalam 500 ml air kelapa. Penelitian ini dharapkan mampu memberikan informasi sumber ntrogen dan komposisi yang tepat agar memperoleh hasil terbaik nata de coco.Kata Kunci: fermentasi, nata de coco, nitrogen, urea
