Analisis Hubungan Kandungan klorofil dan Kelimpahan Plankton di Perairan Kuala Samboja, Kabupaten Kutai Kartanegara, Kalimantan Timur

Abstract

Kuala Samboja is one of the waters in Kutai Kartanegara Regency with high fishery output compared to other sub-districts. This study aims to see the condition of water productivity based on parameters limiting plankton, chlorophyll and other environmental parameters. This research was carried out in August 2021 in Kuala Samboja Waters Kutai Kartanegara, taking samples of plankton, chlorophyll, and water glass parameters taken horizontally in the waters. The instrument used for chlorophyll analysis was a spectrophotometer and analyzed using the American Public Health Association method, while the chemical parameters of the waters were measured in the laboratory. The results of this study found that the environmental quality parameter values were still in the quality standards of the Republic of Indonesia No. 22 of 2021, Lamp VIII (Marine Biota), namely the chlorophyll-a content in the coastal waters of Kuala Samboja ranges from 0.013-0.0975 mg/L and flood plankton ranges from 2835-4158 ind/L, this value is quite high for such waters. The results of the Principal Component Analysis show that the relationship between chlorophyll and plankton is positive, while the results of the relationship between physical and chemical parameters of the waters are negative.
