Abstrak
purposive sampling. Hasil penelitian menunjukkan bahwa kecerahan berkisar antara 6,3-45,5%, kekeruhan 2-4 NTU, suhu 29,6-30,8oC, pH 6,0-7,7, salinitas 0-16 ppt, DO 5,33-6,50 mg/L, BOD 0,4-3,6 mg/L, amonia 0,1-0,32 mg/L, fosfat 0,01-216 mg/L, nitrat 0,006-2,96 mg/L, klorofil-a 1,68-20,6 mg/m3 kelimpahan fitoplankton berkisar (96-240) mg/L. Terdapat hubungan positif antara konsentrasi klorofil-a dengan fitoplankton, fosfat, nitrat, DO, BOD5, secara berturut-turut sebesar 95,5%, 91%, 76,6%, 82,2%, -63%. Semakin tinggi konsentrasi fosfat dan nitrat makin tinggi pula konsentrasi klorofil-a, dan semakin tinggi konsentrasi klorofil-a menyebabkan konsentrasi oksigen terlarut semakin tinggi. Semakin tinggi BOD5 dan amonia maka konsentrasi klorofil-a makin rendah.
