The selection of agro-industrial products is the first step to building superior and prospective agro-industrial products that have a solid and resilient structure in competing based on market opportunities and production capabilities. Agro-industry in ecotourism areas is an alternative approach in strengthening local agro-industry development by integrating all components, including business actors, in developing agro-industrial products. This study aims to determine the priority of prospective products and the added value of agro-industrial products in ecotourism areas. Analysis of the data used includes: (1) prospective agro-industry products with multi-criteria decision analysis using the Bayes method based on expert respondents’ assessments, (2) added value of agro-industrial products using the Hayami method. The study results based on the assessment of expert respondents with multiple criteria including production technology capabilities and skills, market opportunities, commercial value, employment, impact on other products, and investment/business capital indicate that each alternative to agro-industry products has its advantages in each criterion and can assist in making decisions on which agro-industry products can be prioritized products to be developed. The results of the added value calculation using the Hayami method show that all prospective agro-industry products in ecotourism areas have added value and guarantee that industrial players who do business get more significant profit opportunities than selling products in the form of raw materials. The implications of the results of this study can help business actors, ecotourism managers, government, private sector, and stakeholders in developing agro-industrial products in ecotourism areas in an integrated and sustainable manner.
