Abstract

This research was conducted in June 2019 to determined the abudance crown of thorn starfish (A. planci) and the condition of coral reef in Tikus island. 3 Stations with 2 different depth were taken in Tikus island. The result showed that coral reef from 4 meter depth were in middle-good condition. Percent cover of Station 1 was 44.4%, percent cover of Station 2 was 59.33% and percent cover of Station 3 with 59.04%. Meanwhile, 9 meters depth showed coral reef condition in a bad category 13.93-20.20% using Underwater Photograph Transect method. The abudance crown of thorn starfish (A. planci) in all stations were in normal condition with the highest abudance was 0.004 ind/m2 using Line Intercept Transect method. It means that A. planci hasn’t given a threat for coral reef ecosystem. The abudance of A. planci in each station and 2 different depth also didn’t show any different, based on depth and station.
