This study examines how promethee can be a suitable method to be used in the decision-making system of prospective student association members as an organization under the auspices of the university. In this study, it is explained that the decision-making system for the acceptance of prospective student associations as an organization within the university environment experiences several problems in the process, namely, most of the associations still use the manual method. This of course not only has an impact on the effectiveness of the time and energy used but also affects the decisions taken. Promethee is one of the methods in the decision-making system that can be used by students considering that promethee is more efficient in time, effort, and objectivity in making better decisions. Researchers in this study also analyze and describe the scheme or flow of the promethee method that can be used by students as well as basic criteria such as academic, activeness, nature, and confidence possessed. This basic criterion can be one of the reference guidelines used in the selection and decision-making stages.
