THE INFLUENCE OF DEPTH TO PRIMARY PRODUCTIVITY IN BAMA BEACH, BALURAN NATIONAL PARK

Abstract

Bama Beach is one of the beaches used as a tourist destination in Baluran National Park. Coral reefs are coastal ecosystems that have high productivity. This research will study the difference primary productivity of coral reef ecosystems at depth 1 - 10 meter. This study was conducted in Bama Beach on January 2023, with descriptive method. The results of this research showed, the influence of depth to Net Primary Productivity (NPP) is 71,4 % and categorized as good. Net Primary Productivity (NPP) at a depth of 1 meter 62,50 - 90,27 mgC/m2/hour; the depth of 5 meter 17,36 - 52,08 mgC/m2/hour and the depth of 10 meter 8,68 - 34,72 mgC/m2/hour. Net Primary Productivity (NPP) highest at a depth 1 meter, so primary productivity decreases with increasing depth.
