Analysis for ecological and environmental impact ECO factor

16 Figure 13. Suitability map based on average temperature sub-factor Another sub-factor in natural condition factor was land use type. Land use type become very important because it is related to the regulation and legal aspects. Also, based on expert’s judgment, land use type became the most important sub- factor by 0.33. From spatial analysis, mostly of area in Parung was categorized as unsuitable or very unsuitable. Figure 14 shows the suitability map based on land use type sub-factor. Figure 14. Suitability map based on land use type sub-factor Land slope of Parung area was mostly categorized as suitable because Parung has relatively plain land. There were only some area were categorized as unsuitable. Figure 15 shows the suitability map based on land slope sub-factor. 17 Figure 15. Suitability map based on land slope sub-factor After the four sub-factors were processed by weighted overlay, the final suitability map based on natural condition factor was obtained. Figure 16 shows the suitability map based on natural condition factor. Figure 16. Suitability map based on natural condition factor

4. Analysis for natural disaster vulnerability DIS factor

Natural disaster was also considered as important factor because it is related to risk of economic lost minimization. It is recommended for a broiler farm to be not located on a high risk area. Based on data from Agency of Regional Disaster Management BPBD, for flood vulnerability, all area of Parung were categorized as high vulnerability, thus the suitability was very unsuitable as shown by Figure 17a. However, it could not highly affect the suitability because based on expert’s judgment, the importance of natural disaster vulnerability factor was the lowest. Figure 17 shows the suitability map for each sub-factor and also the final suitability map based on natural disaster vulnerability factor. 18 a b c d e f Figure 17.

5. Suitable area based on all factors

Suitability based on all factors was obtained by weighted overlaying the four suitability map of all factors. Figure 18 shows the final suitability map representing suitability of area in Parung for broiler closed house farm.
