Water Quality Analysis for Vannamei Shrimp Culture in Coastal of Banyuwangi Regency

Abstract

The coastal of Banyuwangi Regency is the longest coast and has a high potential for vannamei shrimp culture with the largest production in East Java Province, Indonesia. The sustainability of vannamei shrimp culture depends on seawater input, where water quality is the main thing that must always be considered. The purpose of this study was to analyze water quality for the benefit of vannamei shrimp culture. The method used is descriptive. While data collection using surveys and direct observations, with water quality parameters taken there are 14 types, namely temperature, salinity, pH, DO, alkalinity, ammonia, nitrate, nitrite, phosphate, TOM, TSS, vibrio, redox and plankton. Data analysis used factor analysis based on the Principal Component Analysis (PCA). The results from the calculation of PCA analysis, it can be seen that there are 5 components that are able to describe the overall water quality on the coast of Banyuwangi Regency for the benefit of vannamei shrimp cultivation with a total variance of 80,522%. Component 1 filled with parameters Salinity, Nitrite, Nitrate and Vibrio. Component 2 are pH, TOM and Redox. Component 3 are DO, TOM, TSS and Plankton. Component 4 are Alkalinity, Ammonia, Nitrite and Phosphate. Component 5 are Temperature, Salinity and Plankton.
