Abstract

This study, carried out between May and June 2023, aimed to assess the influence of landfill leachate on environmental conditions, specifically regarding the pollution of river water near the Banyuroto landfill. The parameter of the difference heavy metals in this study are Mercury (Hg), Cadmium (Cd), Lead (Pb), Chromium (Cr), Manganese (Mn), Copper (Cu), and Iron (Fe). The potential ecological risk index is investigated due to the harm to the nearby river ecology. The sampling was conducted at eight discrete locations in close proximity to the dump. The levels of heavy metals were quantified using Atomic Absorption Spectroscopy (AAS). Furthermore, the Potential Ecological Risk (PER) technique was utilized to assess the potential environmental dangers that these metals may pose. The findings unveiled disparate concentrations of heavy metals across the various locations where point 5 of the sampling become most polluted area due to increased anthropogenic activities. The Mercury (Hg) concentrations ranged from 0.014 to 0.032 mg/kg, whereas the Cadmium (Cd) and Chromium (Cr) levels exhibited minimal variation in the below Limit of Detection (LOD). Lead (Pb) exhibited LOD readings, suggesting their minimum presence. The concentrations of Manganese (Mn) and Copper (Cu) were relatively low, whereas Iron (Fe) exhibited the greatest levels, ranging from 0.2405 to 1.2209 mg/l. The maximum potential ecological risk values were calculated and ranked from highest to lowest as follows: Hg (262.19) > Fe (20.35) > Cr (0.374) > Cd (0.245) > Cu (0.297) > Mn (0.100). Remarkably, the possible environmental hazards associated with all heavy metal characteristics constantly remained below the threshold of 40 except the maximum concentration of the total of Heavy Metals. This indicates that their concentrations present a substantial ecological danger in some situations.

Abstract

The increasing of human’s activities caused the pollution load going up. It affected the amount of the Winongo River’s capacity. One of the river management attempts was find out the amount of the capacity with a modeling method. The modeling program in this research was Qual2Kw. The research method was supported by the secondary and primary data treated by the Qual2Kw program. This research was divided in three scenarios. The trial results showed that the BOD concentration in the along of the river was 16 mg/L, the DO concentration was 2.4 mg/L, 7 of pH, and 26oC of temperature. The condition of BOD from the upstream to the downstream in the existing condition had exceeded the quality standards, 3 mg/L. The attempts to decrease the pollution load capacity of Winongo River by 2012 was decreasing the pollution load from the point source 959.25 kg/day and from the diffuser source was 193.75 kg/day. The another effort was making the IPAL Komunal in each sub-districts. Keywords: Winongo River, capacity, Qual2Kw
