2.1.2 Distribution and types of soft coral
There were 35 spesies of hard corals belong to 8
families, and eigth spesies of soft corals belong to 4
genera recorded in the studied site (Table 2). The soft
coral were distributed as follow; 2 species belong to
genus Lobophytum, one species in Nephtea, 3 species
in Sarcophyton and 2 species are belonging Sinularia.
At Pongok Island, six soft coral species were recorded
at PGK2 station and two species found in the PGK1
station. At Tegal Island only two species were
recorded, one of them at MCN1 station, TGL2 and
GSN3 while the other at LHK4 station (Appendix 1).
Appendix 1 Types of soft corals in the study site
Note: The study site of Pongok island of South Bangka

Note: The study site of Tegal island Teluk, Lampung bay
Tegal Island recorded the highest total coral cover
(hard and soft) at GSN3 station with percentage of
about 65.6%, about 36.3% of them represent the soft
coral species; followed by LHK4 station (63.3%) with
soft coral cover was 17% while, MCN1 stations
recorded the lowest coral covers of about 47.7% and
about 16.2% represents soft corals that categorized as
moderate cover (Table 3). At Pongok Island, the
highest coral cover was at PGK1 stations about 50.7%
which is categorized as good with 4.6% soft coral
cover, and PGK2 station about 37% which is
categorized as lowest with soft corals 6.4%.
Diversity indices indicate to two categories of high
and medium coral diversities. PGK2 station showed
the high diversity, meaning spread of high coral
communities and high stability, while the five others
were categorized as moderate diversity.
The rate of equality of the coral communities (E)
showed that two stations (GSN3 and LHK4) with E
values (<0.5) which includes a low rate, which mean
