Abstract
Water catchment area has function to accommodate the discharge of rain water infiltration in the area. The catchment area can performs as a controller of floods and drought in rainy and dry season, respectively. However, now a day many areas in the catchtment have been transformed into settlements and business area that caused reduction in the water catchment area. Suitability of water catchment areas can be identified by several criteria, include: land use area, slope area, rainfall intensity and soil type. In this study Magelang city of Central Java, Indonesia was used as study area. Magelang is a city which is located in a fertile agricultural area and one of the most densely populated regions on Central Java. A fuzzy set assessment has been used to determine 9 (nine) catchment area in the city, while the weighted of each criterion was analyzed using Analytic Hierarchy Process method. Potential of land suitability water store area is classified into four types, include very suitable, suitable, sufficient, and unsuitable areas. The results showed that two areas in the city catchment are categorized very suitable and suitable, while the seven other areas are considered sufficient and unsuitable area
