This community service program aims to improve the competence of Guidance and Counseling students in premarital counseling based on the integration of psychology and Islamic values for Generation Z (Gen-Z). The background is based on BPS data (2023), which shows 60% of divorces occur in couples under 30, as well as research from the Ministry of Religious Affairs' Research and Development Center (Puslitbang Kemenag) (2022), which identified a lack of understanding of premarital relationships as a major cause of young household failure. The methods used include: (1) Interactive talkshow with multidisciplinary speakers (BK lecturers, psychologists, Islamic marriage practitioners), (2) Role-play simulation based on Islamic Conflict Resolution, (3) Digital platform (Slido, animated video of the story of the Prophet-Khadijah) to increase Gen-Z engagement, (4) Workshop on preparing a sharia premarital checklist. The results show that: 1) Increased understanding of the concept of mawaddah wa rahmah from 45% (pre-test) to 88% (post-test), 2) 82% of BK students were able to design integrative premarital counseling scenarios and 95% of participants considered the interactive method more effective than conventional seminars, 3) Supporting factors include institutional support and suitability of the material to the character of Gen-Z (short visual content 10-15 minutes). The main obstacles were limited discussion time (25% of participants proposed a longer duration) and the sensitivity of topics such as financial infidelity (15% of participants). The implemented solutions included online counseling services via Google Meet and collaboration with the Office of Religious Affairs (KUA) for sensitive topics. This program produced the following outputs: 1) A Gen-Z premarital counseling module, 2) An integrative psychology-Islamic guidebook, 3) Educational YouTube videos and scientific publications. Practical implications include recommendations for: 1) Development of digital content (TikTok/Instagram Reels), 2) Certification of premarital counselors with the KUA, 3) Replication of the program through the National HIMA BK network.
