PERANAN PENGGUNAAN LAHAN DI AREA TANGKAPAN SUNGAI TATAARAN TERHADAP EUTROFIKASI DANAU TONDANO

Abstract

ABSTRACT

Eutrophication is a problem faced by the world today. eutrophication is caused
by increasing nutrient concentrations that occur in freshwater ecosystems. Land use
change in this case greatly affects the freshwater ecosystem around the lake. This
study aims to assess the levels of Nitrogen (N) and Phosphorus (P) in the Tataaran
river water flowing into Lake Tondano due land use in the Tataaran river catchment
area. The method used in this research is survey method and determination of
sampling points based on purposive sampling or the determination according to the
research objectives, in this case at the outlet of each land use which is then presented
descriptively for comparison. The results of this study indicate that based on the study
of Nitrogen (N) and Phosphorus (P) levels in the Tataaran river water flowing into Lake
Tondano, the largest contribution transported comes from residential land use, namely
the average N value content is 56.86 mg / seconds and P of 217.64 mg / second.
