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 , and others). Water is an important medium in the operational activities of 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.Keywords : poor sand, batik waste water, koi fish

Abstract

Availability of diet in Sangkuriang catfish (Clarias gariepinus) cultivation is becoming a main concern. One of the problems in the artificial diet is that the protein content could not fully be utilized by the catfish. To solve the problem is by adding papain protease in the artificial diet. This study was conducted to evaluate the effect of papain protease enzyme in artificial diet on diet utilization efficiency and growth performance of sangkuriang catfish (Clarias gariepinus) fingerlings in the Village of Tambaksari, Sub-district of Rowosari, District of Kendal, and Central Java. The fingerlings with initial body weight averaging 4.23±0,30 g were cultivated with the density of 1 fingerling per liter. The fingerlings were obtained from Center for Hacthery, Muntilan. The fingerlings were fed with artificial diet in four different doses of papain enzyme: A (0%), B (0.75%), C (1.5%), and D (2.25%). The experiment used Complete Random Design with 4 (four) treatments and each treatment replicated 3 (three) times. The results show that the addition of papain protease enzyme significantly (P<0.01) affected on the spesific growth rate (SGR) and net protein utilization (NPU). It could be concluded that the addition of papain protease enzyme could increase the specific growth rate (SGR) and net protein utilization (NPU) of Sangkuriang catfish (Clarias gariepinus) fingerlings. Optimum papain protease enzyme dose on the specific growth rate was 2.25% per kg diet. The water quality during study was still in the viable ranges for Sangkuriang catfish (Clarias gariepinus) fingerlings cultivation.Key word: papain protease enzyme, artificial diet, growth, sangkuriang catfish fingerlings
