Environmental risk analysis of The Bedadung Watershed By Using DPSIR

Abstract

Bedadung River is one of the most strategicrivers located in the Bedadung Watershed in Jember. This river crosses Jember with a length of 46,875 meters and it is used as a source of raw water and irrigation as well as a source for PDAM in Jember. Along with many activities of the community, the water pollution load increases significantly. In general, the source of pollution comes from anthropogenic activities in the form of exposure to domestic waste, industrialization, population growth, pesticides and fertilizers, organic and inorganic waste, urban development and weak management systems. This study aims to analyze the environmental risks in the bedadung watershed based on water quality data using DPSIR method. The DPSIR (Driver-Pressure-State-Impact-Response) framework has been used as one of the tools in environmental risk analysis that shows the existence of linear interactions between human activities-pressure and impact. In general, human activities are part of the drivers and human needs that can cause pressure on the environment. This pressure has the potential to cause certain negative impacts that need handling to reduce it. The DPSIR framework which being used is Driver (industry, garbage); Pressure (changes in the chemical composition of water); State (physical and chemical characters); Impact (changes in water quality); and Response (limiting waste disposal to rivers).
