Pengaruh Kromium Heksavalen (VI) terhadap Tingkat Kelangsungan Hidup Ikan Nila (Oreochromis niloticus)
Abstract: Chromium is a heavy
metals, pollutants, and micronutrients that are important to the body. Type of
chromium that has toxic effects to the organism is hexavalent chromium. This
study aims to determine the effect of hexavalent chromium on the survival rate
of tilapia (Oreochromis niloticus). Experimental studies conducted in the
laboratory, using a Completely Randomized Design (CRD) with one treatment
factor, namely the concentration factor. Concentrations of hexavalent chromium
used is 0 ppm (control), 57,69 ppm, 59,94 ppm and 83,20 ppm. The results showed
that hexavalent chromium significantly affect the survival rate of tilapia. The
survival rate of tilapia in a row at a concentration of 57,69 ppm; 59,94 ppm,
and 83,20 ppm for 54,78; 43,08, and 0,33. The conclusions of this study is that
hexavalent chromium concentration of 57,69 ppm; 59,94 ppm, and 83,20 have a
significant influence on the survival rate of tilapia.
