Abstract


Penelitian dilakukan di sekitar keramba apung Waduk Cirata (KJA), Purwakarta, Jawa Barat. Penelitian bertujuan untuk mengetahui fluktuasi ketersediaan oksigen terlarut dalam perairan, melalui percampuran massa air yang diambil dari beberapa kedalaman. Konsentrasi DO di lokasi KJA di Waduk Cirata menurun seiring bertambahnya kedalaman dengan kisaran rata-rata adalah 0,3 - 0,5 mg/l (lapisan dasar) hingga 8,0 - 8,4 mg/l (permukaan). Distribusi vertikal oksigen terlarut menggambarkan tipe perairan clinograde. Kedalaman zona eufotik mencapai 3,81 m. Terdapat variasi ketersediaan oksigen terlarut dari pencampuran massa air meromictic dan holomictic. Pada perlakuan 1 (meromictic hingga 12 m) nilai rata-rata DO yaitu 7,00 - 7,41 mg/l. Perlakuan 2 (meromictic hingga 24 m) nilai rata-rata DO 5,28 - 5,48 mg/l. Perlakuan 3 (holomictic hingga 42 m) memiliki nilai rata-rata DO sebesar 2,44 - 2,84 mg/l. Jika terjadi percampuran meromictic hingga kedalaman 12 m dan 24 m maka kegiatan budidaya ikan masih dianggap layak, karena nilai DO >5 mg/l. Akan tetapi, pencampuran holomictic mengakibatkan DO melewati ambang batas, sehingga tidak dapat menopang budidaya perikanan
