4.2.5.3 Comparison of alternatives
MCA is a set of techniques that including criteria selection, criteria valuation, criteria scores, criteria weights, standardization of scores, aggregation of scores,
ranking and sensitivity test Van Herwijnen 1999. The policy alternatives were compared using multi criteria analysis. To indicate
the relative importance of each effect, it is necessary to assign weights. The pair wise comparison seems to be the best possibilities for expressing the variability related to
the various policy objectives. These comparisons of all pairs of effects are then converted to quantitative weights. The outcome of the analysis is an ordinal ranking of
the alternatives.
4.3 Data requirement and Equipment used
Data uses consisted of both primary and secondary data The primary data are:
• Aerial photograph at scale of 1: 20.000 for land use mapping, • Quick bird image of April 2003
37
• Respondent data from direct interviews, and • Field data from site observation.
The secondary data are: • Land form map
• Topographic map at scale of 1: 25,000 • Administrative boundary map
• Hydrogeology map 1: 100.000 • Literature from related institution

5 V RESULT AND DISCUSSION
5.1 Existing land use
The existing land use map were obtained by interpretation of aerial photograph at 1: 20.000 scale of 2000, Quick Bird image of 2003 and field check that was done in
May 2006. The Map was based on the topographic map at a scale of 1: 25,000. The land use map of the research area is shown in Figure 5.1 consisting of sea water, river,
area settlement, paddy field, non irrigated paddy field, open land, objectarea tourism, and cultivation, mixed hotel settlement and infrastructure, sand dune, bush, dry land
and swamp. Cultivation is a type of dry land that has permanent treatment while dry land itself is only treated temporarily. Bush is natural vegetation grown on an
untreated land. Non irrigated paddy field is a rain depended paddy field, planted normally once a year.

The land coastal are dominated by sandy beach, sand dune, mixed of settlement and hotel, dry land, bush. Table 5.1 shows area paddy field are 18 and
settlement of 12 are distributed in the northern part of sand dune. The 30,19 of the 39
area are dry land, and 12,89 are sandy beach and 10 of sand dune are utilized for tourism area. Based on the information of local community, paddy fields also are
utilized for red onion during the dry season.
