The Simporo Strait is located in the Hendo River Basin. The erosion rate in the Hendo river basin is 12,434,881 m3/year, causing sediment discharge in the Hendo river by 0.00039 m3/year. The high rate of erosion and sediment discharge in the watershed resulted in siltation in the Simporo Strait. In addition to the silting problems, in the Simporo Strait there has also been pollution of the TSS, BOD and COD parameters. This research was conducted in the Simporo Strait with the aim of analyzing the carrying capacity of the Simporo Strait waters for drinking water, recreation, freshwater fish farming, animal husbandry, and water for irrigating crops. The research method uses the water carrying capacity analysis based on water pollution index. The results of the study concluded that the waters in the Simporo Strait have been polluted by TSS, BOD, COD and PO4, so they are not suitable for use as a source of drinking water (Class I) and for the purpose of recreation / tourism (Class II). The carrying capacity of the waters in the Simporo Strait does not support being used as a source of drinking water and a place for infrastructure / recreation facilities because it has been lightly polluted. The carrying capacity of the waters in the Simporo Strait still supports their use as a place for raising freshwater fish, livestock, and water to irrigate crops, because the results of the analysis obtained status meet the quality standards (good condition).
