Abstract

The study was conducted to analyze organic pollution based on protozoa saprobity index and to analyze some environmental parameters that affect the protozoan population in the waters of Bojonegara Banten Bay . Descriptive method with survey techniques used in this study, consisting of 3 observation stations determined based on the presence of different industrial activities. Data were analyzed through calculation of the saprobic index, diversity index and abundance, while the analysis of the relationship of several environmental parameters using the PCA (Principal Component Analysis) program. The results showed that 12 genera of Protozoa were identified with a total of 93 individuals. The waters of Bojonegoro, Banten Bay are already polluted organically with moderate pollution criteria (Beta-meso saprobik) with saprobic index values ranging from 2.30 -2.47, while the environmental parameters that most influence on organic pollution are temperature, pH, turbidity and Biologycal oxygen demand (BOD) )
