Abstract

ABSTRACT

 

The use of high stocking density in nursery causes a decrease of  water quality. Technology that can be used to solvethe low water quality in nursery of giant goramy was phytoremediation using Pistia stratiotes L. Purpose of this research was to determine the best weight ratio between P. stratiotes L. and 33 L water in nursery giant goramy size 3 cm. Giant goramy size 3 cm was maintained in an aquarium and was treated with different weight of P. stratiotes L. consisted of 45 g, 90 g, 135 g, and controls P. stratiotes L. 0 g. Cleaning and water change was done once a week. This research showed that the treatment of P. startiotes L. 45g/33 L water gave the best result in survival rate, absolute length of the growth, specific growth rate, feed efficiency and economically profitable.

ABSTRAK

 

Penggunaan padat tebar tinggi pada pendederan ikan gurami mengakibatkan kualitas air menjadi buruk. Salah satu teknologi yang bisa digunakan untuk mengatasi kualitas air yang buruk pada pendederan ikan gurami adalah fitoremediasi menggunakan tanaman kayu apu. Tujuan penelitian ini adalah menentukan bobot kayu apu dengan volume air 33 L pada pendederan ikan gurami ukuran 3 cm. Ikan gurami ukuran 3 cm dipelihara di dalam akuarium dan diberi perlakuan bobot tanaman kayu apu berbeda yaitu 45 g, 90 g, dan 135 g, serta kontrol  (kayu apu 0 g). Penyiponan dan pergantian air dilakukan setiap satu minggu sekali. Hasil penelitian menunjukkan bahwa perlakuan kayu apu 45 g/33 L air menunjukkan hasil tingkat kelangsungan hidup, pertumbuhan panjang mutlak, laju pertumbuhan bobot harian, efisiensi pakan yang paling baik, serta lebih menguntungkan dibandingkan dengan perlakuan kontrol (kayu apu 0 g).
