This community service activity aims to accelerate digital entrepreneurial capacity and financial accountability among vocational students at SMKN 1 Kota Serang through an integrated intervention approach. The execution method adopted Participatory Action Research (PAR) involving 30 vocational students through interactive training and hands-on mentoring over two days. The curriculum focused on mastering Generative AI-based digital marketing (ChatGPT and Canva AI) alongside operational cash management utilizing the Sepran digital financial application. Quantitative evaluation results demonstrated a significant increase in the participants' average composite score from a pre-test of 45.00 to a post-test of 77.50. This achievement yielded a composite N-Gain Score of 0.59 (Medium/Effective category), statistically validated via a Paired Sample t-test at t (29) = 14.52 (p < 0.001), achieving a 90.00% classical mastery rate. Module-specific analysis revealed a Dual-Speed Learning Curve phenomenon, where AI marketing comprehension (N-Gain = 0.69) surpassed profit management logic (N-Gain = 0.50). This simultaneous synergy effectively establishes an innovative, independent, and accountable vocational edupreneurship ecosystem.
