Bahan organik dalam perairan memerlukan proses perombakan melalui dekomposisi. Penelitian ini bertujuan untuk mengetahui pengaruh dekomposisi bahan organik eceng gondok ( E. crassipes) terhadap NO 3 dan total bakteri. Penelitian dekomposisi bahan organik eceng gondok ini mengacu pada penelitian eksperimental dengan Rancangan Acak Lengkap (RAL) terhadap perlakuan kadar 80%, 60%, dan 40%. Data dikoleksi dengan 3 pengulangan selama 5 kali dengan periode satu minggu. Data yang diukur meliputi kandungan bahan organik, nitrat (NO 3 ), total bakteri, suhu, pH air, dan DO pada setiap wadah percobaan penelitian. Penelitian ini dilaksanakan pada bulan Januari 2015 di Laboratorium Pengelolaan Sumberdaya Ikan dan Lingkungan FPIK UNDIP Tembalang, Semarang. Hasil penelitian adalah dekomposisi eceng gondok memberikan pengaruh yang berbeda terhadap bahan organik air, total bakteri, dan NO 3 . Pengaruh bahan organik pada kadar 80% lebih dari 60%, lebih dari 40%. Pengaruh terhadap total bakteri pada kadar bahan organik 80% lebih dari 60%, lebih dari 40%. Dekomposisi eceng gondok pada kadar bahan organik 80% menghasilkan kelebihan NO 3 , sedangkan dekomposisi eceng gondok dengan kadar bahan organik 60% dan 40% hasil NO 3 cenderung menurun.
