Then theconcentrate of N and P in water sample was analyzed in BARISTAND laboratory.Then the data of N and P That transported from each land uses, was analyzed instatistic with using Randomized Block Design (RBD) and spatial analisis(arcview).The result of research study showed that, each land uses gave effect tothe increase of lake eutrofication. Were in Tondano Lake from Sungean river forN was about 467,1076 mg/day and P was about 5,961849 mg/day. The biggestcontribution of N and P was from residential area, it was 464,2352 mg day-1 ha-1dan 5,961849 mg day-1 ha-1.Keywords : Eutrofikasi, Nutrient, River Of Sungean, Landuse
