This research was motivated by a never-ending questions, which arose in coastal land use conflict especially in Indonesian and generally in developing countries. Policy makers and others stakeholders both in central and local governments concerned with resolution conflict occurred in coastal areas. Squatters, who live and built houses in illegal land, were forced to move out to theirs origin home lands. Suchconflictsoccurredagainandagainwithoutclearsolution among parties involved. Such conflict shows that both squatters and land owners have no benefits in their conflict. Such condition could decrease their economic productivity. As a consequence the economic performance of coastal area become declining. The aim of this research is to analyse coastal land use conflict between squatters and land owners. It includes to formulate conflict resolution based on land optimation. To solve the coastal land conflicts, an economics approach is neededwithassumptionthatconflict isaconcept. As a concept, conflict could be measured by using economic variables called benefits and costs to be taken into account. GAMS (General Algebraic Modelling System) is a computer language which permit formulating economic equilibrium models as systems of nonlinear equations. In this research GAMS was used to calculate the value of land rents. The resultsofGAMSoperationproducesthatthecoastallandarea should be maintained, expanded and added of Squatters.
