Persen Tutupan (Percent Cover) Terumbu Karang Hidup di Perairan Bagian Barat Pulau Rubiah Nanggroe Aceh Darussalam

Abstract

The research of “Percent Cover of Life Coral Reef in the West of Rubiah Island, Nanggroe Aceh Darussalam” was investigated on May 2009. The aimed of this research were to investigated the value of percent cover of life coral and its relation with the value of physic and chemical factors of water. This research is done by Purpossive Random Sampling Method which is determined on 2 stations and depend on activities in each sampling locations. This research using ”Life Intercept Transect” where each stasion within 3 transects in the west of Rubiah. The research showed that percent cover of life coral reef in the west of Rubiah Island including in to almost good with 33,55 %.

There are kinds of growth of coral reef had found, within Acropora as encrusting, submassive, tabulate, digitate and Non-Acropora as encrusting, foliose, massive and submassive. Corelation analys showed that light penetration, light intensity, pH and BOD5 showed strong corelation with the percent cover of life coral reef.
