A change in the total area of developed lands causes the soil to be impervious. The research aims to 1. Measure land use changes, 2. Measure the rainfall volume that runs off on the surface of the developed lands, and 3. Analyze efforts of reducing runoff volume in the developed lands in Bandung Basin. The research employed an analysis of the images of the 2010 Landsat 7 Satellite and 2015 Landsat 8 with remote sensing method. The stages of analysis included Preparation, interpretation, survey, and reporting. The rain intensity was measured with the formula of RI = D x T, while the rainfall volume was measured with the formula of V = R x A. The analysis results show that the area of developed lands changed from 458, 507, 000 m2 to 535, 155, 000 m2. The expansion of the developed lands has caused an increase in the runoff volume, from 11, 737, 779.20 m3 to 13, 699, 968.00 m3. Reducing the runoff volume should be done from every 100 m2 unit of land. The smallest land units should be able to allow rainfall to infiltrate into an infiltration well with a capacity of 8.96 m3. The changed area of developed lands has caused an increase in the amount of runoff. To solve this problem, the regional government should create extension programs and make policies regulating development.
