Pig slaughtering is an industrial activity to produce quality meat for consumption. In addition, pig slaughtering activities also produce waste. Waste generated as remnants of pig slaughtering activities. To overcome of this problem, the countermeasures were made using alternative technology methods, namely phytoremediation, and one of them is the use of water hyacinth plants (Crassipes (Mart) Solm). This study aims to determine the effect of density and contact time of water hyacinth as one of the biological waste treatment techniques in terms of pH value and BOD5 value. The research method is experimental, with four treatments of water hyacinth density i.e. 0%, 30%, 60%, and 90% with observation time, namely days 0, 7, 14, and 28. The results showed that the density of the water hyacinth had no significant effect (p>0.05) on the decrease of pH value of the waste, but the contact time of the water hyacinth had a genuine impact (p<0.05). Likewise, the density of water hyacinth also had no significant effect (p>0.05) on the decrease of BOD5 value, but the contact time had a significant impact (p<0.05) on the reduction of BOD5 value.
