Abstract

Sampean watershed covering the Bondowoso and Situbondo areas are urban watersheds that have strategic significance which need to be specifically managed. Development activities in the Sampean watershed, both upstream and downstream, are highly intensive and population growth is quite high. Changes in land use, as well as increased residential areas in the region upstream, middle and downstream have implications for the entry of pollutants into the Sampean watershed. The aims of this research are: 1) to know the change of land use in Sampean watershed area; 2) to know the progress of river water quality condition in Sampean watershed; 3) to know the pollution load in the Sampean watershed area. This study using the National Sanitation Foundation’s - Water Quality Indeks (NSFWQI) method. NSF-WQI methode consists of 9 parameters such as temperature, tss, turbidity, pH, BOD, DO, Nitrate, Total Phosphate, and Fecal coliform. The results of analysis are : (1) land use change of 1137 ha for settlement (2) monitoring water quality using NSF-IKA metode showed water quality in Sampean river is middle category, (3) BOD and Fecal coliform are the contributing factors of decreasing Sampean River water quality
