Coral growth measurement is a very important information on potential of coral reefs where we can determine time needed for corals to grow accurately. This research was conducted in2 locations,Ujung Gelam beach in westside of Karimunjawa Island and Pancuran beach in eastside of Karimunjawa Island for 3 months started from April – July 2018 and aims to determine the dominant species of branching coral in each area and its percentage cover and to find out the growth rate of branching coral found in those area. This study was conducted with difference-depth treatment which is less than 2 metres and deeper than 2 metres, using 8 branching corals as a samples where each individual takes 3 branches and 3 repetition data.
