Abstract

Fertilizer demand in Indonesia increase for increasing agricultural production.Biofertilizer is organic fertilizer with the addition of specific microorganisms which are expected to reduce the amount of inorganic fertilizer. Carrier material plays an important role in maintaining the viability and storage period. Peat is used as a biofertilizer carrier for  a long time. Solid waste of Modified Cassava Flour (Mocaf) which is the remainder of mocaf industry has great potential as a carrier material of good biofertilizers,  because of its nutrient content. The aim of this study was  determining the potential of mocaf solid waste and its combinations with peat as the carrier in supporting the growth of Nitrogen-fixing Bacteria (NFB) and Phosphate Solubilizing Bacteria (PSB) during the incubation  of microorganisms. The experiment was conducted at the Laboratory of Soil Biology and Biotechnology, Faculty of Agriculture of Sebelas Maret University (UNS) using completely randomized design (CRD) with two factors of a carrier and incubation time as the experimental design. There  were  three  types of  carrier  which  have different  combination. The base material were solid  waste  of  Mocaf  industry   and  peat.  All materials  of carrier  were  mixed and sterilized, than inoculated by Nitrogen- Fixing  Bacteria (NFB)  and  Phosphate Solubilizing  Bacteria (PSB) and incubated  for  60  days. The  growth of  bacterias were analyzed  every 15  days  and  the  chemical composition  of  carrier  were  analyzed  at  the begin and the  end of  research   (incubation).    The results indicated that the incubation time significantlyaffected viability of NFB and PSB. Until 60th day incubation time, still showed the increasing growth of NFB and PSB.

Abstract

Industrial waste supplies contains heavy metals such as Pb which will cause pollution in paddy fields. Remediation of paddy soil contaminated by Pb heavy metal must be done by simple, environmental friendly, cheap and sustainable technology, that is bioremediation. The purpose of this study was to study the effectiveness of bioremediation using Agrobacterium sp. I3 and compost as chelator combined by Mendong plant and NPK fertilizer, and learn the ability of Mendong in uptaking metal soil Pb. This was field experimental research, had a factorial patern, using Completly Randomized Block Design as the base design, with three factors: (1) NPK fertilizers (P0: no NPK fertilizers, P1: with NPK fertilizers), (2) Chelator (K0: no chelator; K1: with chelator Agrobacterium sp. I3 ; K2: with chelator compost); and (3) Plant (T0: without plant; T1: with Mendong plant). The results showed that Agrobacterium sp. I3 and compost were increasing Pb uptake in shoot, but decreasing Pb uptake in root. Mendong plant has highly ability in uptaking soil Pb, so decreased soil Pb, and effective as the phytoremediator. NPK fertilizer increased plant growth so increased Pb uptaken by plant. The highest Pb uptake was in treatment combination of NPK fertilizer + Mendong plant: 80.916 µg, followed by NPK fertilizer + Agrobacterium sp. I3 + Mendong Plant: 76.363 µg. The highest decreased of soil Pb (42.41%) was found in treatment combination of compost + Mendong Plant. Key words: Agrobacterium sp.I3, compost, Fimbristylis sp, Pb, phytoremediation
