Abstract

Contamination of contaminants in river are more due to human activities (antropogenic), such as the disposal of industrial waste and domestic waste. One type of inorganic pollutants that is toxic to living organism including human is cadmium (Cd). The movement of Cd in river water into the soil along the river is naturally and by human activity. The objectives of this study was to examine the distribution of Cd in soil on the river banks of the Cikarang Bekasi Laut (CBL) river, in Bekasi West Java, based on the distance from the pollutant sources during rainy and dry season (spatially and temporally). This study used a survey method in sampling plants, water and soil. Sampling was conducted at 10 sites and 10 observation times (dry and rainy season). The analyses of Cd content were conducted on plant, water and soil samples. In addition, pH was also measured in soil and water samples. Vegetable samples were collected from the field were kale, spinach and caisin. Statistical analyses comparized of analyses of variance (F test), comparatine analyses of the mean and correlation analyses. The results showed that the contents of Cd in the soil samples that close to the surface of the river water were higher than those of other soil samples. This was caused by the movement of Cd from the river water naturally due to changes in water level or river discharge fluctuation, as a consequence of changes in dry and rainy seasons. At sites further from the river (on land of cultivation), the presence of Cd in soil was mainly due to the use of river water for irrigation. Watering plant was mostly done during the dry season, at which the concentration of Cd in river water was relatively higher. The content of Cd in plant tissue (Spinach, kale and caisin) had a positive correlation with the content of Cd in the soil. The average content of Cd from the three plants were spinach > kale > caisin, consecutively. Keywords: antropogenic, cadmium (Cd), Cd uptake, pollution, riverbanks

Abstract

Karakteristik pengikatan ion Cd(II) dan Cu(II) pada polimer imprinted ionik (PII) dari hibrida amino-silika (HAS) yang disintesis menggunakan senyawa 3- aminopropiltrimetoksisilan (3-APTMS) dengan tetraetil ortosilkat (TEOS) sebagai prekursor telah dipelajari. Kontribusi pengikatan ion Cd(II) dan Cu(II) pada sintesis material HAS imprinted ionik Cd(II) dan Cu(II) didominasi oleh interaksi kimia melalui interaksi elekstrotatik sebesar 43,06 ± 0,42 % untuk Cd-HAS dan 40,96 ± 0,21% untuk Cu-HAS, sedangkan pembentukan ikatan kovalen sebesar 50,91 ± 0,25 % untuk Cd-HAS dan 54,87 ± 0,20 % untuk Cu- HAS. Kata kunci : Imprinted ionik, hibrida amino-silika, 3-aminopropiltrimetoksisilan
