APPLICATION OF ANALYTIC HIERARCHY PROCESS FOR SELECTING RIVER RESTORATION POLICY

摘要

River restoration in Indonesia is an important issue because almost 68 % of the river water is classified as heavily polluted. There are several alternatives for restoring the natural state and functioning the river system, which are restoration of species, ecosystem/landscape, and ecosystem services. Selecting river restoration policy is very complex because there is generally a conflict of interests between the various stakeholders. The Analytical Hierarchy Process (AHP) is a multicriteria analysis technique that provides an appropriate tool to accommodate the conflicting views the of various stakeholder groups. The AHP model consists of four levels; goal, criteria, subcriteria, and river restoration alternatives. This study was conducted through questionnaire surveys, which were distributed within the local community of the Sugutamu watershed, the government, and various experts. Furthermore, the results of the questionnaires were processed using Expert Choice 11 software. According to our findings, the main criteria are river water, habitat, action, land use, and cost; the important sub-criteria are water quality, water quantity, biodiversity, species, agriculture, and public education; the best alternative was the restoration of ecosystems services.
