【 摘 要 】

This study aimed to determine the pollution load capacity (DTBP) of Batang Kuranji River against the parameters of Total Suspended Solid (TSS), Biochemical Oxygen Demand (BOD) and Chemical Oxygen Demand (COD). In general, pollutant sources are caused by developments and activities of urban communities such as domestic activities, industry, agriculture and other activities. This research is descriptive quantitative by using Qual2KW method with the sampling location point on the representative of land use located along the kuranji stem river as many as 24 sampling locations, which are divided into 24 segments, spatially from upstream to downstream. The results showed that the parameters of Total Suspended Solid (TSS) were seen from upstream to downstream in the area of sections 8, 10, 14 must be reduced pollution load of 648 kg / day (section 8), 15,552 Kg / day (section 10) and 22,032 Kg / day (section 14), this is due to (1) economic activities of the community in the agricultural sector, in the form of rice fields directly adjacent to the Batang Kuranji river which can cause erosion, (2) livestock sector activities in the form of chicken farming, where the community directly discarding the remnants of chicken feed is discharged directly into the river so that it can increase the pollution load of TSS parameters. Parameters of BOD in Section 6 and Section 16 must be reduced by a pollution load of 453.60 Kg / day (Section 6), 1,308.96 Kg / day (Section 16), This is due to this high pollutant source such as: (1) domestic / domestic waste activities, (2) rice field agriculture. Whereas the COD parameters in areas 3, 7, 14, 15, and 16 must be reduced by 3,862 kg / day (section 3), 16, 783.20 kg / day (section 7), 3,149.28 Kg / day (segment 14), 9,629.28 Kg / day (section 15) and 22,589.28 Kg / day (section 16), this is because there are still many agricultural, plantation and livestock areas so that many sources of pollutants enter the Batang Kuranji river from chemicals organic so that the river water in Batang Kuranji can still accept pollution loads, for the COD parameter the approach is more inorganic chemistry and there are many inorganic chemical compounds in the disposal of liquid waste in the Company / Industry. With the quality conditions of the current Batang Kuranji River in the Padang City segment, control efforts are needed for the pollution. Related to the results of the study, and from the conclusions obtained, the efforts made for optimal control are the application of environmentally sound spatial principles.
