<![CDATA[Background: The scarcity of cadres from Muhammadiyah organizational families is noteworthy. Although fathers dominate involvement, their role in shaping the next generation is often overlooked. Fathers significantly influence family communication and upbringing. Objective: This study evaluates the effectiveness of the "Ayah Ayo Mengasuh" training program in increasing communication intensity in Muhammadiyah organizational families. Method: Subjects are 40 Muhammadiyah families in Magelang. Using Solomon Four Group Design, divided into experimental, control 1, control 2, and control 3 groups. Data collected via a valid and reliable family communication intensity scale. Analyzed with Mann Whitney U Test. Results: Comparison of experimental post-test scores with control 1: Z -3.402, p=0.001 (p<0.05), showing training influence. With control 3: Z -3.506, p=0.000 (p<0.05), confirming increase due to intervention, not pre-test. Conclusion: The training maximizes fathers' roles, impacting cadre emergence through the smallest structure: the family.
