Abstract

This research study aims to assess the effect of Pb2+ ion concentration on the adsorption bioadsorben derived from waste biomass in the form of peanut shell, rice husk and sawdust. This research forms a laboratory experiment with a completely randomized design 2 factor. Factor 1: variation of Pb2+ ion concentration of 0.1, 1, 10, 100 and 1000 ppm. As well as the 2 factors: the type bioadsorben: peanut shell, rice husk and sawdust. Examination of the amount of adsorbed Pb2+ ions using Spectofotometer Atomic Absorption (AAS). Adsorption results showed that the greater the concentration of Pb2+ ions, the greater the ions absorbed by bioadsorben. Optimum absorption concentration at each bioadsorben achieved at 10 ppm, with the value of each absorption is greatest in rice husk 4.036 x 10-3 mg/g, followed by sawdust 3,810 x 10-3 mg/g and a peanut shell 2.819 x 10-3 mg/g. Analyysis of 2 factor analysis showed the presence of intereaksi between Pb 2+ ion concentration variations and types of adsorbents for Pb 2+ ions are adsorption. Key words : Consentration, ion Pb2+, peanut shell, rice husk and sawdust

Abstract

Research has been carried out in the garden 8 Ilir Palembang from August to September 2012, to determine how long the incubation water fern (Azolla pinnata L.) as green manure for cultivation of mustard (Brassica rafa L.). This study used a completely randomized design (CRD) with five treatments were replication 4 times. The long incubation treatment factors are as follows: I1 (7 days), I2 (14 days), I3 (21 days), I4 (28), and I5 (35 days). The results showed that treatment results I5 (42 days) showed the highest yield is 1,00 kg per m2 compared with other treatments. Key  words:  green manure, Azolla pinnata
