Abstract

Potensial role of a macrohydrophyte plant (Veyivera zizanioides) and four semihydrophyte plants (Ipomoea aquatica, Cyperus iria, Commelina nudiflora, Oryza sativa) as remediators of liquid waste of tapioca industry was tested in a glasshouse for 35 days under conditions that resemble to wet and polyculture systems. Results dhowed that all type of plants grew normally on media containing tapioca liquid waste. Total biomass of Ipomoea aquatica and polyculture grown in wet conditions were 32,35 g and 38,44 g, respectively. This were higher than those of control (30,53 g and 36,39 g). Those of V. zizanioides, Cyperus iria, Commelina nudiflora and Oryza sativa were inversely observed. Hawever, V. zizanioides showed the highest tollerance index value (120,99%) compared to that of Ipomoea aquatica (91,21 %), Cyperus iria (56,62 %), Commelina nudiflora (89,63 %), Oryza sativa (83,13 %), and polyculture (62,25 %)

Abstract

A series of experiment had been conducted to elucidate the effects of age and planting system of fragrant root (Vetiveria zizanoides) in improving quality of tapioca industry liquid waste. Eight treatments generated from two planting systems, i.e. hydroponics system (To) and wetland system (T1), and four levels of plant age, i.e. 7 days after planting (LiV1), 45 days after planting (L1V45), 60 days after planting (L1V60), and 75 days after planting (L1V75), were arranged in a randomized block design with three replicates. pH, BOD, COD, DO and CN values were measured periodically for 61 days. Results of the study showed that various age of fragrant root plant were capable of reducing BOD, COD and CN concentrations, as well as increasing DO concentration and pH value for the two planting systems. During remediation process, the LiV75 treatment at wetland system produced better quality of tapioca liquid waste than that of hydroponics system
