Abstract
The sustainability of the ecosystem functions of the Upper Ciliwung Sub Watershed is disrupted, indicated by the exceeding of the minimum erosion hazard level compared to its tolerable erosion. This condition is caused by imbalance between forest areas compared to other land uses such as dryland agricultural, paddy fields, and settlement of the watershed. The purpose of this study was to determine the best watershed management practices in the Upper Ciliwung Sub Watershed based on the watershed sustainability model. The data for the sustainability model were obtained through the Analytical Hierarchy Process (AHP). The results showed that the area of forest had the highest value among other land cover aspects with a value of 52.8%. In succession, the next priority was the area of paddy fields by 24.4%; the area of dryland agriculture was 17.9% and the settlement area was 4.9%. It can be concluded that efforts were needed to: 1). Increase the area of forests and reduce the area of dryland agriculture; 2). Managing the area of settlements; 3). Increasing the area of paddy fields.
