Abstract

Kegiatan budidaya perairan menghasilkan zat buangan berupa amonia, nitrat dan fosfat yang berpotensi menyebabkan pencemaran air sehingga mengganggu kegiatan budidaya perairan. Penggunaan metode filtrasi amonia, nitrat dan fosfat dalam budidaya perairan memiliki kekurangan seperti membutuhkan biaya yang tinggi serta tenaga yang banyak. Salah satu metode filtrasi amonia, nitrat dan fosfat yang sedang dikembangkan adalah biofiltrasi dimana metode ini memanfaatkan tanaman sebagai filter biologis amonia, nitrat dan fosfat. Pada penelitian ini akan dipelajari pengaruh penggunaan tanaman Echinodorus radicans dan Ludwigia octovalvis sebagai biofiltrator terhadap kesehatan ikan nila melalui pengamatan kadar amonia, nitrat dan fosfat perairan, perilaku ikan, kesintasan ikan, laju pertumbuhan spesifik, dan hitung diferensial leukosit. Dalam penelitian ini ikan dipelihara selama 30 hari dalam 3 kelompok perlakuan yang berbeda yaitu A) menggunakan akuarium biofilter Echinodorus radicans B) menggunakan akuarium biofilter Ludwigia octovalvis dan C) kontrol. Parameter yang diujikan dalam penelitian ini meliputi kualitas air, perilaku ikan, laju pertumbuhan spesifik, kesintasan, serta hitung diferensial leukosit. Hasil penelitian menunjukkan bahwa penggunaan E.radicans sebagai biofiltrator dapat menaikkan nilai kesintasan ikan menjadi 70%, laju pertumbuhan spesifik menjadi 0.87% dan persentase limfosit menjadi 69% dibandingkan L. octovalvis dengan kesintasan ikan sebesar 50%, laju pertumbuhan spesifik 0.29% dan persentase limfosit sebesar 64.5% dan kontrol dengan kesintasan 40%, persentase limfosit 0.64% namun dengan laju pertumbuhan spesifik tertinggi yaitu 1.65%

Aquaculture activities produce waste substances in the form of ammonia, nitrate and phosphate which have the potential to cause water pollution, thus disrupting aquaculture activities. The use of ammonia, nitrate and phosphate filtration methods in aquaculture has disadvantages such as requiring high costs and a lot of labour. One of the filtration methods of ammonia, nitrate and phosphate that is being developed is biofiltration where this method utilises plants as biological filters of ammonia, nitrate and phosphate. This research will study the effect of using Echinodorus radicans and Ludwigia octovalvis plants as biofilters on tilapia health through observations of ammonia, nitrate and phosphate levels, fish behaviour, fish survival, specific growth rate, and leukocyte differential count. In this study, fish were reared for 30 days in 3 different treatment groups, namely A) using Echinodorus radicans biofilter aquarium B) using Ludwigia octovalvis biofilter aquarium and C) control. Parameters tested in this study included water quality, fish behaviour, specific growth rate, survival, and leukocyte differential count. The results showed that the use of E. radicans as biofiltrator can increase the fish survival value to 70%, specific growth rate to 0.87% and lymphocyte percentage to 69% compared to L. octovalvis with fish survival of 50%, specific growth rate of 0.29% and lymphocyte percentage of 64.5% and control with 40% survival, lymphocyte percentage of 0.64% but with the highest specific growth rate of 1.65%.
