摘要

This study is aimed to determine the differences of the soft corals between sheltered and exposed area in Pongok Island, Soulth of Bangka and Tegal Island in Lampung Bay, Indonesia. The physical-chemical parameters of waters were measured in the field and laboratorium. Soft coral types and cover s were measured using line intercept transect (LIT) and quadrant transects methods. Eigtht types of soft corals classified in four genera (Lobophytum, Nephthea, Sarcophyton and Sinularia) were found i n both sites, six species were identified in the waters of South Bangka (at 9 meters depth) and two species (at 3 meters depth). In Tegal Island waters (closed waters), only 3 species from the genus Sinularia were recorded (at 2-5m depth). There were 2 station s at Pongok Island namely, PGK1 and PGK2, while in Tegal Island, there were 4 station s namely MCN1, TGL2, GSN3 dan LHK4. Coral diversity w as considered as medium category, similarity index es w ere low to moderate, except at PGK2 station was considered high, and for the level of dominance , there were no type of coral that dominates. Principal component analyses showed that both waters can be classified based on their physic al -chemical characteristic, which were turbidity, temperature, depth, currents, phosphate, nitrate and substrate type.
