Early pregnancy detection is vital for reducing maternal and neonatal mortality, yet first trimester antenatal care (K1) visits at Sukorejo community health center remain low at only 24.66% during January- May 2026, according to the MCH regional report. Passive service delivery models, low health literacy, and persistent socio-cultural myths drive this gap. Roda Sisir Ibu Hamil (ROSI Bumil) innovation was developed to empower health cadres as essential community links for active screening and monitoring. Seventy-three health cadres at Puskesmas Sukorejo participated in structured training on early pregnancy screening using innovative tools: ROSI Bumil, Kasir Bu MiJo, and Buku SAPA Ibu. The health cadres' knowledge was assessed before and after the training, and the results were analyzed using the Wilcoxon signed-rank test. Cadre knowledge increased significantly following the intervention (p< 0.001), rising from 21.9% to 95.9% in the “good knowledge” category. Cadre identified six new pregnant women who had not yet done an early pregnancy visit during the two-week active door-to-door pregnancy screening period. The ROSI Bumil program was associated with a significant improvement in cadre knowledge and facilitated the identification of a new pregnant woman. The intervention may complement routine pregnancy surveillance through community-based screening and digital reporting.
