<![CDATA[The rise of digital platforms has transformed altruistic action into measurable, scalable online participation, yet studies of how digital altruism is structurally formed within environmental sociopreneurship remain limited, particularly from a behavioral stakeholder perspective. This study aims to analyze how Motivation, Opportunity, and Ability (MoA) interact to shape sustained multistakeholder digital altruism on LindungiHutan.com. This research adopts a qualitative descriptive case study within a constructivist paradigm, using in-depth interviews with ten key organizational and grassroots informants, website observation, and digital documentation. Data were analyzed through iterative coding and pattern matching guided by the MoA framework and stakeholder theory. The findings reveal that digital altruism on LindungiHutan.com emerges from the alignment of moral–environmental motivations, platform-based participation opportunities, and technological and organizational capabilities. The platform successfully integrates conservation farmers, volunteers, campaign initiators, donors, corporate partners, and institutions into a measurable digital participation ecosystem. Digital participation is not driven by isolated individual generosity, but by the orchestration of MoA within a multistakeholder system supported by trust, strategic communication, and platform design. Theoretically, this study strengthens MoA as a relevant behavioral framework for explaining digital altruism in environmental sociopreneurship. In practice, the findings provide strategic guidance for social platforms and organizations on designing participatory infrastructures that foster sustained prosocial engagement and environmental impact.]]>
