Transport Nutrien penyebab Eutrofikasi dari Daerah Tangkapan Air Waduk Mrica Banjarnegara
Abstrak: The transport of
nutrien causing eutrophication in water from catchment area especially fosforus
(P) through runoff is determined by type of landuses, slop, soils type, and
land cover (Jeje,2006). The research was conducted using a survey method. The
sampling technique was done by a purposive sampling on any flooding in the
rivers that pass through areas with specific land use (settlement, forest,
plantations, agricultural fields and rice field). The main parameters were
river discharge and the content of nutrients causing eutrophication that was
phosphorus (P) in rivers. The P loadingfrom cacthment area to Mrica reservoir
was 11,526,706.14 kg/year and the load allocation (LA) was 3,833,587.70
kg/year. The reservoir operational of power generating dan flushing activity
were able to manage the LA up to 1,147,329.09kg/year, so the TMDL of Mrica
reservoir become 4,980,916.78kg/year. It was concluded that the highest
transport of P was from paddy field and then followed by respectivelly
agricultural (potato) field, plantation (perhutani) field, settlement area, and
forest area.
