ABSTRACT: Objective: This research aims to examine the factors that influence the Repeat Intentions and Attitudes of Plasma/Blood donors through analyzing the relationship between E-WoM and Perceived Value (Emotional, Social, Altruistic & Functional) towards Attitude and together with Subjective Norm, Perceived Behavioral Control and Social Media which will have a positive influence on Intention, especially for Plasma/Blood donor activities. Research Method: The research method used is Quantitative research type and the data collection method is Survey with questionnaires, and the analysis technique uses structural equation modeling (SEM) analysis for hypothesis testing. Data collection was carried out by survey at the end of September 2025 to the beginning of October 2025 with a total of 302 respondents. Findings: The findings of this research are that 7 (seven) hypotheses are supported and 2 (two) hypotheses are not supported, the Emotional Value and Social Value factors do not directly have a positive effect on Attitude, but rather act as post-behavior confirmation and supporting factors in building positive perceptions. The positive influence of social media and online recommendations in shaping Attitudes and increasing trust is also an important aspect that can strengthen plasma/ blood donor Intentions. Research Implications and Limitations: Research implications show the importance of using Social Media and online recommendations (Electronic Word-of-Mouth) in building positive Attitudes and Intention to donate Plasma/Blood. Subjective Norms and Social Influence show a significant influence on Plasma/Blood Intention. Campaigns must emphasize personal benefits, ease of procedures, and life-saving effects so that positive Attitudes are formed, not only on social aspects or external recognition. Research limitations are location and sample limitations, less honest subject responses or social desirability bias and limited time and resources. Originality: In this research, there is novelty which will become Research Originality, namely adding Social Media which directly influences Intention.
