In addition, environmental parameters measurements include temperature, dissolved oxygen (DO), salinity, pH, light penetration and current velocity. Analysis of photo data using CPCe application. The results indicated that the condition of coral reefs in Kayu Angin Genteng Island belongs to enough category and the condition of water quality still supports coral life.
