Abstract

Cirebon Regency is experiencing flood and drought problems where this area is experiencing a change in land use from green areas to housing due to population growth. This change causes a decrease in the land's ability to absorb water and an increase in water runoff. This research aims to analyze the application of environmentally friendly drainage with retention ponds to overcome this problem. The case study was conducted in a new housing complex with an area of 49.2 ha. The design method of the retention pond is related to the Directorate General of Human Settlements. The results of the research at the site required three retention ponds with a volume of 3,543.60 m3, 4,443.30 m3 and 2,303.40 m3. The efficiencies of reducing runoff water for each pond are 32%, 37%, and 21%. The total reduction efficiency of the three ponds is 90%. The remaining 10% of the runoff water goes into the drainage canal. If you want to implement zero waste, the remaining runoff water can be captured by building absorption wells at several points. The application of this environmentally friendly drainage concept has the effect of reducing runoff water and increasing infiltration water.

Abstract

This study analyzes the increase in runoff caused by residential development in Sumber, Cirebon Regency, West Java. Housing development causes land conversion into impervious areas, which reduces rainwater infiltration and potentially increases the risk of downstream flooding. This study uses the calculation of runoff discharge before and after development, the rational method to measure runoff discharge. The predicted pre-development runoff was 0.205 m³/sec, which increased to 0.685 m³/sec after the development was completed; the potential increase in runoff was 0.481 m³/sec. The results show the significant impact of the development on the increase in runoff and potential flood risk. As a solution, environmentally sound drainage practices such as detention ponds and infiltration wells were developed to reduce the impact.

Abstract

Heavy metal pollution in river ecosystems has the potential to disrupt the environmental balance and endanger human health, thus requiring a study of metal content in water and sediment segments. This study aims to analyze the concentrations of cadmium (Cd), chromium (Cr), and copper (Cu) in river water and sediments and compare them with the quality standards set by Government Regulation No. 22 of 2021. Sampling was conducted purposively at several stations in the upper, middle, and lower reaches of the river, then analyzed using Atomic Absorption Spectrophotometry (AAS) after undergoing preparation and wet destruction processes. The results showed that the levels of Cd, Cr, and Cu in sediments were generally higher than in water, indicating the role of sediments as a medium for metal accumulation. At point 3, the concentration of Cu in the sediment exceeded the ISQC Low ANZECC threshold value of >65 mg/kg, while the Cr and Cu levels in the water exceeded the class 2 quality standards of >0.05 and >0.02 mg/L. Overall, the quality of river water and sediment is greatly influenced by industrial waste, thus requiring efforts to control sources of pollution and regular monitoring in the study area.
