 ABSTRACT Comparative studies on  nutrient uptake ability of rice plants (Oryza Sativa.L) that represent groups of plants dicotyledonous with long beans (Vigna sinensis) representative of the group of plants monocotyledonous have been conducted. The study was conducted on a community farm located in the Village of Sungai Sapih  Padang, at plants are used as the sample is sokan varieties. The root of leaves and fruit as well as beans, the same parts are used as sample.Morphological observations of roots, leaves and fruit using the SEM showed the difference between the rice and beans. While the homogenity for fruit rice and beans especially almost the same. The results of nutrient measurements performed by ICP - MS, elemental carbon is the largest percentage of nutrients in the two plants in average above 50% in all parts of the plant. The percentage of Ca, Mg and N elements in the leaves of beans is higher than in the rice leaves, otherwise the percentage of Si element is higher in the rice plants. Key words: absorption, nutrients, Oryza sativa, Vigna sinensis, ICP-MS

Abstract

Jengkol shells (Pithecellobium jiringa) an agricultural waste from typical Indonesian plant has been investigated for its ability to absorb heavy metal ions Cr VI and Cr III . Effect of pH, concentration, contact time, mass and the speed of stirring biosorben studied by extraction method. Concentration of metal ions Cr VI and Cr III was measured using Atomic Absorption Spectrophotometer (AAS). The optimum conditions for metal ion uptake of Cr VI occurs at pH 4, the concentration of 7000 mg/L, contact time of 60 minutes, 0.1 g biosorben mass and stirring speed 100 rpm. For the metal ions Cr III wa obtained conditions optimum at pH 5, the concentration of 1500 mg/L,  contact time of 60 minutes, 0.1 g biosorben mass and stirring speed 100 rpm. Functional groups contained in the jengkol shells analyzed by Fourier Transform Infra Red (FTIR). Data equilibrium uptake of metal ions Cr VI and Cr III  by the jengkol shells analyzed using two isotherm models , namely Langmuir and Freundlich isotherm models . The absorption of both the metal ions tend to follow the Langmuir isotherm models in which the absorption capacity of metal ions obtained for Cr VI ) and Cr  III  is 24.9376 mg / g and 39. 0625 mg /g . The optimum condition was applied to study the river Batang Arau at Padang city obtained a capacity of 15.065 mg/ g with 45 efficiency, 94 % for the uptake of metal ions Cr (total).
