Abstract

The water quality of coastal waters of Ternate Island has decreased, marked by an increase in the pollution index on several physical and chemical parameters in the last decade. The purpose of this study was to analyze and determine the pollution level of the coastal waters of Ternate Island based on several physical, chemical, and biological parameters. Research field data collection was carried out at 6 stations, namely Rua, Jambula, Sasa, Bastiong, Gamalama and Takome Villages which represented the characteristics of the waters with different human activities. The results of this research showed that the pollution level of the coastal waters of Ternate Island was in the moderately polluted category. There were eight physical, chemical, and biological parameters that were analyzed and two parameters had exceeded the water quality standard for marine life, namely the concentration of nitrate and phosphate, while the other parameters were still below the water quality standard.
