Abstract

The condition of the Upper Ciliwung Watershed’s Minimum Erosion Hazard value is still far from expected, since the value is still greater than one. The sustainability of watershed functions is influenced by the value of Minimum Erosion Hazard Rate, Farmer's Revenue, and Food Crop Production Results. The purpose of this research is to build calculation method of Sustainability Index of Watershed Function (IKFD) of Upper Ciliwung and to know the condition of Upper Ciliwung Watershed sustainability. The method of this research is mix method that combine quantitative and qualitative data. Data analysis was done by using Analytical Hierarchy Process (AHP). Based on the method used in this study, the authors build the calculation formula IKFD as follows: IKFD = (ITBEM × 72.8%) + (IPPet × 15.3%) + (IPTPa × 11.9%). The final calculation of IKFD Upper Ciliwung is done through the sum of the multiplication of the AHP value of each indicator with the real condition value of each indicator. After the Upper Ciliwung Watershed Index is obtained, then it is categorized into category classes based on the distribution of figures in the index calculation. The Sustainability Index Value of Upper Ciliwung Watershed Function at present is 30.7% and goes into very less level.
