Abstract

Paddy fields in the Rancaekek area, Bandung Regency-Indonesia, has been contaminated by textile wastewater. The area needs to recover back to its normal condition and function. Several compounds were found in the soil, such as Cu, Zn, Pb, Cd, Co, Ni, and Cr. Phytoremediation was selected as a site remediation strategy, which employs plants to remove non-volatile and immiscible soil contents. The objective of the study was to determine the ability of Equisetum debile to absorb Cu from the contaminated soil. Cu measurement was conducted by using the AAS (Atomic Absorption Spectrophotometer) method. The study has shown that Equisetum debile can absorb Cu concentrations of up to 25.3 ppm in 60 days after initial planting. However, the Enrichment Coefficient value (0.392) indicated that Equisetum debile was not efficient as a hyperaccumulator plant.

Abstract

Aim: This study has been done to investigate the contamination in the main open channel using mathematical modeling to describe the pollutant transport of groundwater around the Cicabe final disposal site, Mandalajati Village, Bandung (coordinate 6°53'50"S; 107°39'48"E). Methodology and Result: This research was conducted in the irrigation channel that crossed next to Cicabe former waste disposal site. Pollutant parameter studied was Chromium (Cr) in water and sediment. To determine the pollutant transport along flow was using the equation of 1-dimensional analytical model based on advection–dispersion phenomena. The sampling was done twice for model calibration and validation. The samples collected included sediment and water. Pollutant input generated from leachate, domestic waste, and the open channel. The Cr simulation for k = 3 x 10-4/sec resulted that the model concentration was quite valid to approach observed Cr in observation and calibration. Simulations also done each segment to approach Cr observation with k1 = 2.5x10-4/sec, k2 = 1.1 x 10-3/sec, and k3 = 0/sec. Conclusion, significance and impact study: Cr concentration in the water met the quality standard according to PP 82/2011, while the Cr concentrations in sediment were above the US-EPA standard (2004). The simulation result for calibration and validation with k=1.4x10-4 Cr/sec showed the model was sufficient approaching the observed Cr. The Cr simulation indicated that the Cr had decayed as evidenced by the quite high Cr concentration in sediment.
