Uji Toksisitas Deterjen Cair terhadap Kelangsungan Hidup Benih Ikan Nila (Oreochromis niloticus)

Abstract

Waste water from liquid detergent produced by household activities as a component of water pollution. The waste dumped into water without prior treatment, and may cause the death of aquatic biota. This study aims to determine the toxic effects caused by liquid detergen, with preliminary, and definitive test in: 0 ppm, 17.78 ppm, 31.62 ppm, 56.23 ppm, 100 ppm concentrations of liquid detergent, and, with three replications. O. niloticus 700 fish seed of was used, with size of 3-5 cm and a weight of 0.65 to 0.78 g. Data were analyzed by the method of Hubbert. These results indicated that the liquid detergent had the fish toxicant and high detergent concentrations increased the toxicity. The concentration of liquid detergent for LC 50 96 was 79.4 ppm. This solution of liquid detergent at 79.4 ppm killed test by 50% in 96 hours. High detergent concentration in biota reduced the DO and increased temperature, which both environmental factors might cause the death of fish in the waters.
