Fuzzy Multi Attribute Decision Making (FMADM) for Land Use Management
Journal Title: Academic Research International - Year 2014, Vol 5, Issue 2
Abstract
Jeneberang Basin is situated in South Sulawesi, Indonesia. In the recent years, the function of this basin could not be performed optimally in maintaining sustainability hydrologic function of Jeneberang dam. Therefore, in order to maintain the hydrologic function of the dam, it is necessary to formulate suitable landuse at upstream of the river basin. This research is objected to formulate policy for the suitable landuse, in term of reducing sedimentation rate in Jeneberang Dam. This study employed RUSLE (Revised Universal Soil Loss Equation) for calculating of erosion as well as sedimentation rate. Fuzzy Multi Attribute Decision Making (FMADM) and Analytic Hierarchy Process (AHP) whichis combined with Geographical Information System (GIS) were employed for obtaining the formulation. AHP was applied for obtaining of weighting factor that ware used to formulate optimum landuse at the upstream. There are ten conservation alternatives were observed (natural mulch,plastic mulch, strip cropping, crop rotation, cover crops application, plough paralleled with contour, terrace, agro forestry, tree cultivation and replanting) by considering seven criteria (material availability, farmer knowledge, acceptance level of technology, supporting of institution, suitability of farming system, financial affordability, others criteria). The result of this study indicated that, the value of intersection vector of 0.799 is attributed to the conservation practice of crop rotation. From the research, it was proved that by applying of FMADM, sedimentation rate can be reduced of 18.43 m3/km2/year becomes 4.63 m3/km2/year.
