Detect location by using GPS Suitability based on form input

29 Figure 33. On field validation for point 1 expected: very unsuitable Based on field survey, point 1 was located on a residential and close to waterbody small river as shown in Figure 33. So it was predicted that the suitability of the point is very unsuitable or unsuitable. Figure 34. System result based on coordinate of point 1 showing that location was very unsuitable Based on system running, the same result was also obtained. The system categorized the location as very unsuitable, as shown in Figure 34. The reasoning system also gave the same characteristic as seen on the field, such as the location was exactly on the residential area, location was too close to waterbody, and location was on high risk of natural disaster. Figure 35. On field validation for point 2 expected: unsuitable 30 Point 2 was also located on a residential area, but the population was not as dense as was point 1, as shown in Figure 35. This point was predicted as unsuitable location. Figure 36. System result based on coordinate of point 2 showing that location was unsuitable Based on system running, the same result was also obtained. The system categorized the location as unsuitable, as shown in Figure 36. The reasoning system also gave the same characteristic as seen on the field, such as the location was exactly on the residential area, and location was on high risk of natural disaster. Figure 37. On field validation for point 3 expected: moderate Point 3 was located on an agricultural land, yet it was located in the middle of low density settlement area, as shown in Figure 37. Based on this physical characteristic, it was predicted that the location would be categorized as moderate. Figure 38. System result based on coordinate of point 3 showing that location was moderate 31 Based on system running, the same result was also obtained. The system categorized the location as moderate, as shown in Figure 38. There was no reasoning because reasoning will only displayed if the location is categorized as very unsuitable or unsuitable. Figure 39. On field validation for point 4 expected: suitable Point 4 was located in the middle of an agricultural land, as shown by Figure 39. Based on this physical characteristic, it was predicted that the location would be categorized as suitable or very unsuitable. Based on system running, the same result was also obtained. The system categorized the location as suitable, as shown by Figure 40. Figure 40. System result based on coordinate of point 4 showing that location was suitable 4 CONCLUSION AND RECOMMENDATION A suitability map for broiler closed house farm in Parung region considering ecological and environmental impact, economic and infrastructure, natural condition, and natural disaster vulnerability has been created. Also, based on the suitability map, an expert system for selecting broiler closed house farm location has been developed. This system can be used as a tool to determine suitability of a location, either in Parung region or other location in Indonesia.
