Effect of Water Quality Parameters on Total Bacteria Vibrio sp. in The Coastal Waters of Banyuwangi Regency

Abstract Banyuwangi coastal is used for several fishery activities consisting of fishing, and aquaculture. Vibrio is a type of saprophytic bacteria that lives in freshwater, sea water and soil. Water quality conditions affect the presence of Vibrio sp. bacteria. In the previous study, if the temperature and salinity values in the waters are getting higher, then followed by the amount of Vibrio sp. This study aims to determine the total Vibrio sp. and their relationship with water quality parameters. The method used is the descriptive method. The data analysis used is multiple linear regression analysis. Water quality consisting of phosphate, dissolved oxygen (DO), nitrit (NO 2 − ) and total organic matter (TOM) together has significant effect on the total Vibrio sp (Sig. < 0.05). Partial test results of water quality on total Vibrio sp. has a P-value of phosphate value of (0.245 X1), DO (0.103 X2), Nitrite (0.029 X3), and TOM (0.218 X4). The results of this test are known to be the value of nitrite variable Sig.0.029 (Sig.<0.05) which means that it has a significant effect on the total value of Vibrio sp. Based on multiple linear regression analysis, the regression equation is obtained which is Y = −19.534 X1 − 169.86 X2 + 26.68 X2 + 14.28 X3.
