Salinity: refractometer (in situ) pH: pH meter (in situ) Phosphates: Hach PhosVer 3 Ascorbic Acid Powder Pillows using spectrophotometer and adjusted with standard curve. Nitrates: observed through quartz cuvette at 220 nm using spectrophotometer and adjusted with standard curve. Raw land use data is from Indonesian Geospatial Information Agency (BIG) and analyzed using the open-source geospatial information system qGIS. A buffer zone of 5 km around each river was generated and analyzed for percentage of each land use - major land uses include residential, irrigated and seasonal rice fields, and farmland.
