The complexity of the main organized parameters in water quality of aquatic is very diverse then an instrument that is needed to reduce it by Factor Analysis (FA). This study aims to (1) identified water quality profile in the study sites; (2) compared value’s of significance between the study sites; (3) analyzed limiting factors of the water quality component in the Rawa Danau Panggang (RDP) ecosystem. Data collection was conducted from July to December 2017, at 12 sampling sites. Sampling location from land use, ie Without Activity (TA) as STA 1, Reservat (RV) using STA 2, Settlement (PM) for STA 3, Shepherd (PK) is STA 4. The mean difference values between STA indicated that the brightness, currents, pH, NO3, PO4, BOD5, primary productivity and DO have significantly different values. The used of 7 parameters (primary productivity, DO, brightness, BOD5, pH and temperature) gave estimation value’s of eigen > 1 occur 3 main water quality limiting group. Results of factor analysis into 3 new components of oxygen demand (consisting of productivity parameters, DO, brightness). Pollution with BOD5 and pH, even temperature.
