Aplikasi AGNPS untuk Menganalisis Kualitas Air Sungai Ciujung Kabupaten Serang, Banten

Abstract

The water quality of river is affected by quality of water supply from the catchment area. The quality of water supply from catcment area associated with human activity. Human activities that affect the water quality also occured in Ciujung watershed in Banten Province. In this research, the decline of water quality from agricultural activities. Agricultural land in this watershed still large. The objective of this research is to analyze the water quality based on N, P, and COD parameters by using AGNPS. This application is a model that used to simulate and nutrient transport in catchment area. The methods that has been done is the gridding phase. The result showed that the water quality of Ciujung has descreased because of the organic matter. In the existing condition of the river, BOD, COD, DO, Cu and Cr parameters not contained the criteria of water quality class II. Based on the results of AGNPS simulation model, COD, N and P water quuality fits the criteria for class II based for agricultural activity
