Quality Analysis Of Aquaculture Waste Disposal Water Body In Kampung Papuyu Banjar Regency Through Pollution Index And Phytoplankton Diversity Index

Abstract

BSTRACT Village Papuyu is a papuyu cultivation area in Banjar Regency, which has the potential to produce organic waste that can contaminate the surrounding waters. It is necessary to conduct research to determine the quality of water in the water where the aquaculture waste is disposed of by using the pollution index method and phytoplankton bioindicators. The research was conducted from March to April 2022, by taking plankton samples and physico- chemical parameters at 5 stations in the cultivation area. The results obtained are that the condition of the waters in the water bodies of aquaculture waste disposal is categorized as lightly polluted based on a pollution index of 3.1685 with parameters that do not comply with quality standards, namely color, ammonia and phosphate, and the moderately polluted category seen from the phytoplankton diversity index (H'). that is equal to 1.7055. Phytoplankton qualitative analysis obtained 20 species, consisting of 3 phytoplankton phyla, namely Cyanophyta (2 species), Chlorophyta (9 species), and Chrysophyta (9 species).
