In an integrated approach, watershed management crucially needed to maintain condition and quality of watershed. Land use change is one of main causes of watershed condition and quality changing. Therefore, it required planning alternatives suggestions to prevent and recover the watershed degradation. The research was carried out to study about watershed changes and degradation due to land use change and investigating for the best alternative to restore Ciujung Watershed, Banten, Indonesia using Soil and Water Assessment Tool (SWAT) model. Research result showed that the reduced of forest area (plantation forest, primary dryland forest, secondary dryland forest) and the increased of dryland agricultural, dryland mixed farming (mixed with bush, plantation, rice fields and bushes) caused the increase of river flow. Several alternative soil and water conservation techniques as if reforestation, agroforestry, strip cropping, contour cropping, dam building and the application of bio-retention hole could be done for land management to maintain and improve the condition and quality of Ciujung Watershed which is indicated by a decrease in values of River Regime Coefficient (RRC), surface runoff coefficient, and sediment yield.
