Abstract
Sludge is one of the wastes produced by the paper industry which has the potential to be used as an ameliorant material. However, the obstacle is that sludge is considered a toxic and dangerous material because of the presence of heavy metals in it, especially the heavy metal Pb. The aims of this study was to determine the amount of heavy metals accumulated in cocopeat and biochar planting media combined with sludge paper waste, roots and leaves of the Brassica juncea plant as accumulator plants. The pot experimental was set up in a Single Factor Randomized Group Design consisting of 6 treatments and 3 replications. The treatment used was a combination of planting media (cocopeat and biochar) with sludge paper waste consisting of treatments A (cocopeat), B (biochar), C (cocopeat + paper sludge organic fertilizer 3:1), D (biochar + fertilizer paper sludge organic fertilizer 3:1), E (cocopeat + paper sludge organic fertilizer 1:1), F (biochar + paper sludge organic fertilizer 1:1). The results showed that biochar media had a higher accumulation of heavy metal Pb in plant roots, while cocopeat media translocated more to leaves. The study showed that biochar and cocopeat media are effectiive media capable of accumulating and translocating the heavy metal Pb, both in the planting medium and into plant tissue However, the value of the Translocation Factor in each treatment was included in the low category, namely TF<1.
