<![CDATA[Urban ecology is a new paradigm in viewing cities as a separate ecosystem, an ecosystem dominated by humans. One important component in urban ecology is the natural system, where rivers are part of an important hydrological system. As the largest river in West Kalimantan, the Kapuas River flows from Kapuas Hulu Regency to Kubu Raya Regency on the downstream side and through Pontianak City. Riparian areas are areas with the highest biodiversity index. Riparian areas are the areas most threatened by human activities and human land use patterns. Panjang Island is a large island downstream of the Kapuas River, which divides the Kapuas River into the Kapuas Besar River and the Kapuas Kecil River, as well as the Panjang Strait which reconnects the two rivers. The Panjang Island is an ecosystem that greatly influences the quality of the Kapuas River. This study was carried out to identify water quality by taking water samples and measuring them in the laboratory, with the results that the water quality for Kapuas Kecil had a TDS value of 57 mg/L, which is better than the Panjang Strait and the Kapuas Besar River. Meanwhile, the COD value for the Kapuas Besar River is higher, namely 89 mg/L, so the quality is less good than the Kapuas Kecil River or Panjang Strait. This is of course influenced by the vegetation and landscape patterns in the Panjang Island riparian area, where varied and layered vegetation types produce better water quality. To find out this pattern, digital vegetation mapping was carried out on Panjang Island, using an urban ecology approach.]]>
