Tingkat Pencemaran Berdasarkan Saprobitas Fitoplankton di Bungkutoko, Kota Kendari, Provinsi Sulawesi Tenggara Level of Pollution Based On Phytoplankton Saprobity In Bungkutoko, Kendari City, Southeast Sulawesi Province
Main Article Content
Abstract
Phytoplankton which is the main producer of organic substances, plays an important role in waters and can also be used as a parameter for the level of water pollution because phytoplankton have a very fast response to changes in water quality. This research aimed to determine the level of pollution in Bungkutoko waters based on phytoplankton probity by utilizing data on the abundance, diversity index, uniformity index, and phytoplankton dominance index in Bungkutoko waters. This research used a purposive sampling method to determine the stations. From the research results, phytoplankton abundance ranged from 66 cells/L 698 cells/L. The phytoplankton diversity index in Bungkutoko ranges from 1.54 2.42. This showed that the diversity values at all observation stations are included in the medium diversity category. The phytoplankton uniformity index value ranges from 0.58 0.9. This indicated that the uniformity index is moderate. The phytoplankton dominance value ranges from 0.10 0.34. This displayed that there is no dominant type of phytoplankton. The Saprobic Index (SI) value obtained was 0.65 and the Saprobic Index (TSI) value was -0.16. This revealed that Bungkutoko waters were categorized as lightly/lowly polluted to moderately polluted.
