THE RELATIONSHIP WATER QUALITY STATUS METHODS POLLUTION INDEX WITH ACTIVITIES OF FLOATING NET CAGE IN THE RIAM KANAN DAM
This study aims to determine the status of water quality in the Riam Kanan Reservoir seen from the physical parameters (Temperature and Brightness) and chemical parameters (pH, DO, Total Phosphate, Nitrate and Ammonia) using Pollution Index (IP) method, knowing trophic level in Riam Kanan reservoir seen from the parameter of Brightness, Total Phosphate and Total Nitrogen and know the influence of floating net cage activity to water quality status of Riam Kanan reservoir.Of the result on measurement of IP method water quality which based on the, the status of water quality in station 1, 2, and 3 was complied with water quality standard (good condition), either for class I, II, III, or IV. Based on the regulation of the state minister for environment Number 28 Year 2009 was found that the fertility level in station 1, 2, and 3 was in the same trophic status, which was oligotrophic. The value of thit nitrate (X1), total P (X2) and ammonia (X3) either for class I, II, III, or IV was lower than ttabel for significance in 5% or sig/.probability > 0,05 which meant that H0 was accepted; KJA activities did not affect the water quality status of Riam Kanan dam.
