PENETAPAN DAYA TAMPUNG BEBAN PENCEMAR TUKAD MATI DI KABUPATEN BADUNG DENGAN MODEL QUAL2KW 5.1

Ecotrophic: Journal of Environmental Science, 2017
  ABSTRAK Tukad Mati is one of watershed that is flow through two regencies of Badung and Denpasar that has 12 km length. Tukad Mati functioned as irrigation, drainage system and as the exile of wastewater from all activities along the river. Because of the pollution, the water quality has degraded. The source of pollution is organic matter
