This paper describes application of fuzzy logic for predicting the competitiveness of

agroindustry of carrageenan and to develop strategy for enhancing it. Fuzzy expert system is

used to predict the competitiveness using sustainable competitive advantage perspective with

four inputs, such as production amount, a place to compete, competitor, and customer service.

Knowledge base management system is constructed using rule based production type, whereas

inference mechanism is developed using Mamdani’s inference system. Matlab’s Fuzzy Toolbox

Ver 6.5 is used to design system implementation. Scenarios is constructed to improve the
