3.3.2 Collecting Data Method
Primary data was collected from observation, measurement and review directly in the field study. Ecological data was collected with instrument prepared
and Scuba Set.
3.3.2.1 Physical-Chemistry Parameters
The measurement of physical-chemistry parameters were observed at each sites research which used to analyzing of environment condition. The parameters
were measured directly in the field by using instruments and the results are obtained directly through the reading of the scale from instruments.
The physical-chemistry parameters include depth, temperature, salinity, visibility, current, pH, dissolved oxygen, and the ocean substrate. Basically, the
methods of measuring are as follows: a. Depth
The measurement of depth at the sites of coral reefs conducted by the depth meter on scuba sets whereas the measurement of depth on water quality
conducted by the grab sampler. b. Temperature and Salinity
The measurement of temperature and Salinity was conducted by reading scale on Thermometer and Hand-refractometer instrument.
c. Current Velocity of current at each research sites was measured by using the floater
drudge. The direction of current determined by release of floater drudge in the early position until the last position. Whereas the velocity of current recorded
by tightened the rope of floater drudge in one time. d. Dissolved oxygen and pH
Parameters of dissolved oxygen DO and pH were measured by reading scale on DO meter and pH meter instrument.
3.3.2.2 Coral Reefs Condition
Collection data on coral reef condition at each site research was performed by using the method Line Intercept Transect LIT. The LIT used to see the
percentage of coral coverage. Transect with 50 meters placed parallel to the coastline which observed along the 30 meters with 3 three replicates. The
interval between replications is 10 ten meters and each transect at a distance of 00-10 meters, 20-30 meters and 40-50 meters. Observations of coral lifeform and
substrate recorded with accurate in centimeters size Coremap II-LIPI 2007; English et al. 1997; Hill Wilkinson 2004. Benthic categories were observed in
the research are as follows: Table 2 Benthic category in the condition of coral reef data acquisition
Benthic codes
Description
ACB Colonies have both primary and secondary open branching, where branches are generally narrower
than they are long ACT
Horizontal plates with a small area of basal attachment, where the colony is at least twice as wide as they are high
ACS Colony surface forms columns andor ridges and may have encrusting edges
ACE Colonies adhere and encrust the substrate and have very little vertical growth
ACD Short, protruding, vertically orientated digit like branches arising from an encrusting base
CM Colony is of generally solid construction and the same shape in all directions hemispherical in
shape CS
Colony has knobs, protrusions or columnar structures or rounded and more than 50 of the colony raised indiscreetly from the underlying substratum
CF Colony leaf-like in appearance or composed of flattened sheets which may be fused or convoluted to
form whorls CE
Colonies that adhere and encrust the substrate CB
Arborescent corals with open primary and secondary branching where branches are generally narrower than they are wide
AA Colony of makroalga
CA This category includes all substrate and rubble covered with coralline algae
CHL Coral of the genus Heliopora
CME Coral of the genus Millepora
CMR Unattached easily moved solitary Fungiid coral.
DC Recently dead coral which has a white or off-white colour and not yet colonised by turfing algae.
DCA Dead coral with algae
HA Macro algae of the genus Halimeda.
MA Includes all macro algae with structure features 5cm in size
OT All identifiable organisms that associated with coral reef
R Fragments of dead hard coral 0.5cm but 15cm in diameter which are not consolidated into a hard
or stable substrate RCK
Substrate not colonised by visible benthic organisms. Rarely seen except where the reef has recently undergone exfoliation e.g. due to a cyclone, or where terrestrial rocks have not been colonised.
S Sand Ranging from fine silt to calcareous sediment to Halimeda spp. fragments, 0.5cm in diameter
SC Soft Coral
SI Silt
SP Includes all sponges SP.
TA Turf algae encrust the substrate and have no distinguishable structural features TA.
ZO Zooanthids organism

3.3.2.3 Reef Fishes Condition
Collection data of reef fishes was conducted by using Fish Underwater Visual Census UVC method. This method recorded the number of fish that
appear in the belt transect area. The position and length of transects was similar with the position of LIT. Censuses conducted with a radius of view of 5 five
meter above the path transect which the pairs of transects is 2.5 m left and 2.5 m right side of transect line. Hence, the area observed at each transect is 5 x 50m =
250 m

The reef fish were divided into 3 three groups:
b. Targets, the targets fish are economically important and common fish caught
for consumption. Usually they are made of coral reefs as spawning and nests nursery ground. The target fish families represented Serranidae, Lutjanidae,
Lethrinidae, Nemipteridae, Caesionidae, Siganidae, Haemulidae and Acanthuridae;
c. Indicators, the indicators fish are the kinds of typical reef fish inhabit the
coral reef ecosystem and is an indicator of fertility area. These fish represented the family Chaetodontidae, Pomachantidae, Zanclidae, and
several species of the family Acanthuridae, Scorpaenidae, Balistidae and Scaridae;
Major, the majors fish are small fish species or 5-25 cm with a variety of staining characteristics and knowing as ornamental fish. These groups are
generally found in abundance, both in number and individual. In addition these fish tend to be territorial and all their life was in coral reefs.
Represented of these fish are Pomacentridae, Apogonidae, Labridae and Blenniidae.

3.3.2.4 Social Conditions
Data of social condition, collected on all villages in Pasi Island. The respondent is chosen in order to catch ideal respondent purposive sampling and
respondent are as follows: society of fishermen, community leaders and government. Hereinafter the perception of chosen respondent could be evaluated
by an interview, questioner and mini workshop. The public perception and MCA zoning plan is also needed as additional
data. Based on their needs and interests respondents were also given the opportunity to assess and advice on the design of multipurpose zoning of MCA in
Pasi Island. It also requires the information of all stakeholders communities, fishermen, local government about the activities can be done within MCA. This
is certainly expected to be an input in the management model of MCA Pasi Island.
3.3.2.5 Secondary Data
Secondary data being collected from document or released by some institution, i.e. Department Marine and Fisheries of Kepulauan Selayar Regency,
COREMAP II Selayar, and BPS.
3.4 Boundaries and MCA Zones
Determination of boundaries and multipurpose zoning of MCA will facilitate local governments in preserving and monitoring of ecosystems in coastal
regions and small islands. Steps for developing zoning maps and boundary of MCA are presented below:
