Figure 4 Steps for developing zoning maps and boundary of MCA.
3.4.1 Preliminary Design
Determination of preliminary design of the core zone was conducted prior to the survey based on secondary information and data that already exist. The
enactment of the draft core zone will make it easier to conduct the next stage. This initial draft will be offered to stakeholders.
3.4.2 Public Consultation
The public consultation with stakeholders was conducted after preparation of the draft map MCA’s core zone to gather their perceptions of early design
stage. This data is also compiled with data society conditions and the biophysical data.
3.4.3 MCA Mapping
The above data are analyzed. In this step of research, data being interpreted phases are as: 1 weighting and scoring, 2 overlay, and 3 development of
boundaries and multipurpose zoning of marine conservation areas. Table 2 shows a sample presentation of MCA boundaries:

3.5 Data Analysis
Data analysis was conducted after data collecting as a mean to answer of some question and problem of research. In this network research, data being
analyzed are as follow:
3.5.1 Biophysics Data

Suitability Analysis for MCA Core Zone
The determination of suitability criteria for the core zone of MCA was conducted by weighting and scoring based on several criteria which have been
determined. Criteria for the suitability of the core zone are as follows.

Getting a core zone of the assessment criteria need to know the interval for each class of suitability which a minimum score of 12 and a maximum score of
36. The formula is as follow:
ik = 36-123 = 8
With the interval class 8, then got the suitability criteria for the core zone as follows
Highly Suitable S1 : score 29 - 36 :
Suitable S2 : score 20 - 28
Not Suitable N : score 12 – 19
3.5.3 Suitability Analysis for Mariculture
Determination of the feasibility for aquaculture development was conducted by weighting method. Detailed data on physical and chemical waters was used as
reference in determining the eligibility criteria. The Method of scoring or weighting of each parameter is calculated with different weightings. The weights
used depend on the experimental or empirical experience that has been done. The
feasibility factors of aquaculture are presented in the following table:
