Abstract :
This study analyzes the economic growth of Banten Province and river water quality (as environmental indicator) one decade after decentralization. Descriptive and multivariate statistics were used in data analysis. The results showed that Banten Province has achieved well economic growth. Its GDP has contributed to approximately 14.75% of the national GDP. At the same time, the population growth has increased significantly with an annual rate of 2.78. Nine physicochemical elements in Ciujung River showed increasing trends, especially in the last five years. Some parameters even exceeded their ambient values. Among the heavy metals, seven elements exhibited intensifying
concentrations. Out of seven, iron has exceeded its ambient level. The organic materials in Ciujung River were also very high, indicated by the level of KMnO4 and Escherichia coli concentration. The multivariate statistics revealed that, although some elements showed intensifying concentrations, seasonal variability still played an important role in the water quality changes.
