Modeling Multi-criteria for Land Suitability Evaluation of the Plantation and Horticulture Plants (Case Study: Lembang and Around)

(Indonesia), Master of Science in Land Evaluation (Bogor Agricultural University)

Thesis Abstract:

 

The study aimed to examine the physical land suitability evaluation for cabbage, potato, carrot, and quinine in Lembang and around using multi-criteria evaluation (MCE) model and compare land evaluation methods (limitation, parametric, and computerized MCE). The type of computerized MCE procedure was chosen using weighted linear combination (WLC) that needed input criteria as constraint and factor. The criteria were the output of matching between land characteristics for each land mapping unit with land requirements (by Agriculture Department) for each plant. Constraint was reclassified to gain the criteria parameter as suitable (1) or not suitable (0). Factor was weighted by pairwise comparison matrix and all would sum up to one. Since the suitability class by the Agriculture Department (1997) was divided into four classes, the factor values (scale 0-255 as byte binary in computer) were as follows: 0-101 (0-25%) as N (not suitable), 102-152 (26-50%) as S3 (marginally suitable), 153-203 (51-75%) as S2 (moderately suitable), and 204- 255 (76-100%) as S1 (suitable). Results of the study showed that vegetable field land use in the research area based on production tended to belong to S2 class. Based on sustainability, land was marginally suitable (S3) for horticulture (cabbage, potato, and carrot) plants. Overall, the research area was suitable (S1) for quinine plantation based on production and sustainability. It was also found that the computerized MCE and parametric methods were more compatible with field production for a long time than the limitation method. However, based on sustainability, the limitation method was more acceptable. The computerized MCE as the part of geographic information system (GIS) has the ability to evaluate land for large areas.
