Nitrogen (N) and phosphorus (P) are nutrients or chemical content needed by living things, one of which is plants.This content can be transported by run off to rivers or water bodies so that it has an impact on soil fertility and high content in rivers causing eutrophication (water pollution).This can be accelerated by human activitie, namely land use patterns.Therefore, efforts in controlling the impact through value or cost approach in the form of water treatment in minimizing the content of N and P in rivers and fertilization costs on land use patterns in restoring soil fertility. This study aims to (1) analyze the content of N and P rivers in each land use outlet; (2) know how much value or water treatment in minimizing the content of N and P in the river and the cost of fertilization on the pattern of land use in restoring soil fertility. This research is a descriptive type of research using a survey method that is to take samples and water observations by purposive sampling. Water sampling was conducted at four different land use outlets in Bulan Sub-Watershed of the which is the upstream Jeneberang Watershed that serves as a catchment area for water and water suppliers in Bili-Bili Reservoir as well as water raw materials of Tirta Jeneberang Municipal Waterworks. The results showed that the use of agricultural forest land chemical content in the form of N and P is greater than pine forest. In addition, pine forest outlets can save water treatment costs in minimizing N and P by IDR 2.747.946.765 while the cost of fertilization on agricultural land is 5-6 times greater tha pine forest
