ABSTRACT: Batik Indonesia
became more famous after gaining recognition from the United Nations Edutional,
Scientific and Cultural Organization (UNESCO). Batik-making is certainly
generate waste and pollution , many batik industry that drain effluent
wastewater to flow - the flow of water around, causing the flow of polluted
water, declining water quality and damage aquatic life (fish, microorganisms ,

aquaculture , this is because the water functions as the survival of fish . The
use of poor sand as a filter in an aqueous medium batik waste koi care also
determine the effect the survival of fish in the media proficiency level with
the treatment of poor sand different, and knowing the poor sand capable of
being a substrate that is able to purify water because it has a composition of
CaO , Al2O3 and FeO. In testing the media by way of poor sand substrate put the
aquarium bottom (sedimentation), clearly visible color change that occurs at
the beginning of batik waste water colored dark red to green translucent (for 5
-day precipitation) . Treatment with the best survival percentage in C is 86.76
% (800 g) and D (1000 g) percentage of 93.33 % , while in treatment A (control)
fish dying and treatment D percentage of fish life is very low at 13 , 33 % with
poor sand 600gr . The test results stated poor sand able to be purifying
(demineralization) water.
