The Ciliwung Watershed is one of the watersheds that flows through Jakarta. The Ciliwung River has social and economic functions for the lives of the people around it as well as ecosystems for various organisms. However, this function has been increasingly eroded due to very severe river pollution. This condition is exacerbated by the use of riverbanks for the construction of residences, offices and other commercial areas that contribute to the increase of pollutants. Good management of the Ciliwung watershed is one of the important efforts made to improve the city of Jakarta. This study aims to assess the economic aspects of the Ciliwung watershed to support efforts to restore and manage the Ciliwung River in a sustainable manner. The economic value of this watershed was calculated using a non-market based approach and the Contingent Valuation Method (CVM). Based on the valuation carried out, the estimated economic value of the Ciliwung watershed is IDR 991,000,000,000.
