Clustering human perception of environment impact using Rough Set Theory

Abstract

Yogyakarta, as the main destination for education, cultural exchange, and tourism in Indonesia has experienced a high demand on physical development. Despite its positive effect, the growth of physical development in Yogyakarta also brings several negative effects. This research aims to figure out the various effect of physical development in Yogyakarta based on the perception of the local residence. To achieve the objective, this research uses two methods based on rough set theory, that are Maximum dependency attribute (MDA) and fuzzy partition based on indiscernible relation (FKP). The results show that the water quality is the important attribute on physical and chemical aspects. Furthermore, on economic aspect, the highest attributes are immigration and employee absorption.
