| dc.description.abstract | Lau borus is an outlet who located on Lau Kawar Lake. the location of lau borus is
located at the foot of mount sinabung where this mountain has experienced quite high
eruptive activity for several years. Determination of the status of water quality in these
waters using the Pollution Index method following the Minister of Environment
Regulation number 115 of 2003 and Minister of Health Regulation number 32 of 2017
with the parameters to be tested in this research are TDS, pH, Fe, SO4, COD , BOD, Cu,
Cl, Pb, NH3, Total Coliform. With 3 sample points taken by purposive sampling. The
average results of the calculation of the Lau Borus Waters Pollution Index method Outlet
Lau Kawar Lightly Polluted Lake (scores between 0.79 to 1.15). While the results of
PERMENKES number 32 of 2017 the total coliform results show that this value has
exceeded the average value. From these results, the quality status is influenced by
pollutants from Total Coliform which are above the quality standard. The relationship
between the eruption activity of Mount Sinabung and the quality of Lau Borus during
sampling did not cause a significant pollution impact due to volcanic ash pollutants. The
cause of Lau Borus pollution is from the direction of the eruption wind towards the Lau
Borus Lake Lau Kawar Outlet, which is relatively small compared to the opposite
direction, where the percentage of the eruption wind direction is towards Lau Kawar
Lake. the direction of the lake in the opposite direction is 1: 8. | en_US |
