The action taken for post-mining critical land reclamation is physical reclamation followed by biological reclamation, i.e. planting vegetation (revegetation). The alternative action for post-mining critical land reclamation is the use of river sediment sludge as an soil ameliorant. This study aims to determine the growth of plant and litter production of Antocephalus cadamba Miq. On post-mining land. The experimental design used was completely randomized design, with the treatment of planting media in the form of a mixture of river sediment-sludge with topsoil material. There are five treatment of planting media, namely: P0 (without river sediment); P1 (25% river sediment); P2 (50% river sediment); P3 (75% river sediment), and P4 (100% river sediment). Each treatment was repeated four times. Observations were made on the physical properties of planting media and the growth of plant (A. cadamba), namely: soil bulk density, soil texture, soil pore, litter weight, content of N, P and K of litter, plant height, and diameter of stem. Results showed a decrease in percentage of clay fraction when the A.cadamba plant was three months old at all treatments, except P4; while the soil bulk density increases. The percentage of micro pores increases with increasing percentage of river sediment, while total pore decreases, except for P4 treatment. The addition of river sediment on topsoil material as a planting medium was able to increase the litter production of A.cadamba. The N-content of litter was highest in treatment P2, while the content of P and K of litter was highest in P3 treatment. Increased plant height and stem diameter occurred along with the increasing percentage of addition of river sediment on planting medium up to the P3 treatment. © 2018, GEOMATE International Society.
