3.4 Data Sources

The data distribution for point of sample in this location has identified and delineated as marine coastal suitability. Mainly the data used for this research is acquired from Pramono 2009. This is done by identifying the parameters such as salinity, temperature, dissolved oxygen, brightness, depth and acidity from point of research that are measurements from field. This data consist as describe in table 2-6, and also for next process use as based on spatial interpolation. Table 2-6 Data distribution for point of sample Number points of research 20 points of sample Number of parameters 6 parameters Date and time 10 -12Nov2008 and 1 pm - 5 pm Weather condition Cloudy Marine condition Steadywave Data distribution for point of observation has identified for potential cultivation such as seaweed and pearl oyster. This data is produced from collecting data from field after calculation the spatial polygon map. The information of cultivation in this point of observation as showed in table 2-7. This data use for validation as number points of observation for seaweed and pearl oyster cultivation. Table 2-7 Data Distribution for point of observation Number point of observation 40 point of observations Date and time 30-31May2009, 8 am – 12 am weather condition Good weather marine condition Steadywave 27 IV. RESULTS AND DISCUSSIONS Generally, analysis of marine coastal suitability is computing several physical parameters in a particular location, which comparison between the criteria of classification and rule requirements should be fulfilled for a particular commodity in order to obtain maximum production. These criteria of physical parameters are called “marine suitability” when maximum value of all physical parameter criteria is the highest value and also vice versa if the criteria of physical parameter conditions outside of the desired value with the desired sentence is indicated as not suitable.

4.1 The Constraints of the Research

Before discussing results, there are some limitations of this works to be aware and the limitations as follows: • Marine coastal suitability evaluation is based on bio-physical parameters. The process did not accommodate cultural and economic evaluations such as annual income of fishermen. • The sample points in this study are considered not sufficient, so it could influence the process of spatial interpolation. • This study did not consider the effect of seasonal change within a year, where in rainy season, seaweed and pearl oyster cultivation are much affected.
