Land resources are increasingly important as the population continues to grow, which will put pressure on demand, so land use is increasingly competitive. The purpose of this study is to determine the interrelationships between economic sectors between DKI Jakarta and Bodetabek and the impact of DKI Jakarta’s economic development on the economy and changes in land use in Bodetabek. Research using IRIO approach and analysis of Landsat imagery. The sector in DKI Jakarta that has an effect on Bodetabek is the trade sector. Food industry, building, restaurant and hotel, communication, building and service business,. On the other hand, the sectors in Bodetabek that affect DKI Jakarta are the chemical, wood, and metal goods industries. According to the IRIO table, an area of 2,561.86 ha of built land is needed in DKI Jakarta and 251,167.57 ha in DKI Jakarta and 251,167.57 ha while the results of the interpretation of TM7 images in 2010 and 2019 mean that the built area of Bodetabek has changed from 183,681.86 ha to 249,867.91 ha. or has increased to 66,186,05 ha. There is a difference in calculations with the IRIO table and image interpretation of 1,299.66 ha. The land cover of the Ciliwung Hulu watershed was obtained through analysis of Landsat imagery data and 2019 was dry land agriculture of 4435 ha in 2019. A sizeable reduction also occurred in paddy fields and forest cover of 2% each. The reduction in forest area to dry land agriculture causes disruption of hydrological functions and higher erosion
