Abstract

Soybean productivity should be increased because of the increasingly strong demand. One method is the large of plant area. Therefore calcareous soil can be used as an alternative grown medium, but the contrains in the calcareous soil should be overcome. On of alternative effort to overcome the deficiencies of nutrients in the calcareous soil is the addition of Trichoderma compost and vesicular arbuscular mycorrhizal (VAM). The purpose of this study was to determine the influence of the compost on the soybean grown on the calcareous soil. Experimental study was conducted using Randomized Completely Block Design (RCBD) by a factor of Trichoderma compost treatment (0 g, 15 g, 30 g and 45 g) with six replications. Measured parameters were the percentage of mycorrhizal infection, the percentage of active root nodules, plant height, root length, biomass of soybean. Data were analyzed using one-way ANAVA and continued to by the LSD if there were a significant different. The results showed that of compost consist Trichoderma and VAM affected significantly on the percentage of VAM infection, the percentage of active root nodules, plant height, root length, and biomass plants. The most optimal concentration of Trichoderma compost from all five parameters is 45 grams.

Abstract

The Paper Industry produces minor product in the form of sewage especially liquid sewage in a very large volume which contains of heavy metals Pb.  Furthermore,  this sewage is usually discharged into the water  which causes pollution. An effort is required to minimize the content of Pb metal before being discharged into waters, including the use of Genjer plants as the agent of phytoremediation. This study aims to determine the ability of Genjer plants to absorb the Lead metals (Pb) from liquid paper waste. The research is accomplished by doing an experiment that uses a Randomized Block Design (RGD) with two treatment factors, the biomass plant and length of exposure time. The treatment factor of plant biomass is 0 g, 50 g, 100 g and 150 g. The factor of exposure time is for 7 days, 14 days and 21 days. The parameters which are observed include the levels of Pb in the liquid paper waste, in roots of Genjer plants and leaves of Genjer plants. The analysis of Pb levels uses ICP that is done at the Energy Studies and Engineering Laboratory, Sepuluh November Institute of Technology (ITS), Surabaya. The data are statistically analyzed using 2-way Anava and further test, Duncant Multiple Range Test (DMRT). The result shows that biomass of Genjer plants and exposure time affect to the ability of Genjer plants to absorb Pb metals in liquid paper waste paper. The most optimal decrease of Pb levels occurs in the treatment of biomass Genjer 150 grams with exposure time for 21 days which is equal to 0.4688 mg / l (80.09%). Genjer plants can absorb and accumulate Pb. The highest accumulation of Pb in the root is 1.1546 mg / l (26.1%), and in the leaves is 0.1120 mg / l (21.9%), both occur at 150 g biomass treatment and exposure time of 21 days. Thus the Genjer plant can be used as fitoremediator heavy Lead metal (Pb) in the liquid paper waste.
