Abstract
Bedadung River is one of the Regional Strategic Rivers located in the Bedadung Watershed in Jember Regency. This river crosses Jember Regency with a length of 46,875 meters and is used as a source of raw water and irrigation as well as a source for PDAM Jember Regency. Along with the many activities of the community, the water pollution load is increasing. 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 the DPSIR method. The DPSIR (Driver-Pressure-State-Impact-Response) Framework has long 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 represent drivers and human needs that can cause pressure on the environment and potentially cause certain negative impacts that need to be responded to to reduce them. The DPSIR framework to be used is Driver (industry, garbage); Pressure (changes in the chemical composition of water); State (physical and chemical characters); Impact (changes in water quality); Response (limiting waste disposal to rivers).
