Abstract

Seed of Mikroorganisme from river mud sediment that sampling of Tebe counted ± 10 gr. Phase of seeding with
capasity of 3 litre (sediment) of Tebe, was counted by 3 gr, NPK = 2,5 gr, Mgso4.7H2O = 0,2 gr, and aquades until
border. Aerasi is conducted by using given aerator into seed place. Growth of microorganism was measured of each
every 2 day during one week with measuring value of biomass till reach price 2000 mg / L. After seed process, into
treatment place aeraeration of process of seeding domestic waste water and each counted 500 mL. Variation of nutrient
treatment (NPK) respectely 0,25 gr, 0,50 gr, 0,75 gr and 1.00 gr while control without addition of nutrient. Process is
measured by value of pH, COD on 1, 3, 5, and 7 day.
Result of research show that Sediment River of Tebe have potency as active mud. This matter is showed with
growth of biomass of microbe till reach number 3.610 mg / L. Addition variation of NPK at treat of domestic waste have
an effect on very real to value of COD. Best Result with value of COD lowest that is 38,096 mg / L with its effectiveness
to 91,11% at addition of NPK counted 0,5 gr.
