Abstract

This study aims to analyze the carrying capacity of the coastal waters of Blekok and the coast of Kerapu, Situbondo, East Java as a conservation area for mangroves, blekok birds and grouper fish cultivation. The study used the in situ observation method, carried out in January–February 2021. The sampling was on Blekok beach at latitude coordinates: -7.69742 and longitude: 113.92206, on Kerapu beach at latitude coordinates: -7.69568 and longitude: 113.89666. At each beach the data is taken at 3 stations, at each station 3 sub stations are taken. Parameters measured include physical (temperature, turbidity, TSS, TDS), chemical (pH, salinity, DO, BOD, Cu), and biology (total Coliform) were measured in situ and at the Environmental Laboratory, Situbondo Environmental Service. Analysis of Cu concentration using Atomic Absorption Spectrophotometer method. Coliform total analysis used the Most Probable Number method. The data were analyzed descriptively qualitative-quantitatively and compared with the quality standard of the Minister of Environment Decree No. 51/2004. The results showed that the physical, chemical, and biological parameters of the coastal waters of Blekok and Kerapu beaches were in accordance with quality standards so the carrying capacity as a mangrove conservation area, blekok birds, grouper cultivation and tourism is very good.
