<![CDATA[Tofu industrial activities in Indonesia are dominated by small-scale businesses with limited capital and production which is still done with simple technology. Tofu liquid waste contains a lot of organic and inorganic compounds that can disrupt the microbial life in water and pollute the environment,so that it needs treatment before being discharged directly into water. Phytoremediation is one alternative method of wastewater treatment processes by using plants or microorganisms as hyperacumulator. This study aims to determine the length of the absorption process of kiambang (salvinamolesta) and determine the influence of the weight of kiambang (salvinamolesta) in reducing the levels of COD and TSS in tofu’s wastewater. Waste treatment usesbucket as media with volume 5 L that is filled by liquid waste out with composition 1: 5 (tofu’s wastewater : water) and volume 3 L. Variables in this research areweight of kiambang(100 g, 250 g and 500 g) and absorption’s time (2 days, 4 days, 6 days and 8 days). The results showed that the best length of time of absorption is about 8days to decrease level of COD and TSS, with a percentage degradation of COD TSS 87.10% and 98.46%. And the best weight of kiambang to decrease levels of COD and TSS is about 250 g.]]>
