BIROKRASI DAN KEADILAN DALAM HUKUM KELUARGA ISLAM IMPLEMENTASI SIMKAH DI KUA KOTA SERANGNIM.: 23203011158Muhammad FadhlurrohmanauthorThe government, through Minister of Religious Affairs Decree No. 892 of 2019, mandates the use of the web-based SIMKAH (Marriage Management Information System) for marriage registration. This system aims to improve service efficiency, data transparency, and prevent irregularities such as falsification of marriage documents, unauthorized polygamy, and unregistered marriages. However, in practice, SIMKAH implementation still faces various technical and social obstacles that impact the effectiveness of marriage administration services in the community. This study aims to analyze the level of public awareness of the Marriage Management Information System (SIMKAH) policy at the Serang City Office of Religious Affairs (KUA), their views on its implementation in marriage administration services, and assess whether SIMKAH implementation has been able to achieve civil administration that provides justice for the community. This research uses a juridical-empirical approach to examine the suitability of the SIMKAH policy implementation at the Serang City KUA and to examine how the system contributes to justice in family administration. The data in this study consist of primary and secondary data. Primary data was obtained through interviews with 10 Serang City Office of Religious Affairs (KUA) employees and 15 prospective brides and grooms, as well as observations of the SIMKAH-based marriage administration service process at the KUA. Secondary data were obtained from six official documents, KUA archives, statistical data, scientific literature, and visual documentation to strengthen the field findings. The research analysis utilized theories of justice and public policy to assess the relationship between policy, bureaucracy, and public services, as well as the protection of community rights in marriage administration through SIMKAH. This study shows that: first, public knowledge of the SIMKAH policy at the KUA in Serang City varies, consisting of two groups: one group understands and is aware of SIMKAH's existence, while the other group understands it but still experiences limitations in operating SIMKAH, particularly in technical aspects. Second, the community perceives SIMKAH as providing fairness and order in Muslim marriage administration services at the KUA in Serang City. The community also perceives SIMKAH as facilitating access to marriage registration. Although they understand and perceive it as providing convenience, some are unable to do so independently and still require assistance from KUA officers. However, some have done so independently, and still encounter several obstacles such as limited access to technology or network disruptions. Therefore, it is necessary to increase socialization and improve the system to realize fairer, more effective, and inclusive services.346.01 Hukum Keluarga - Hukum Pernikahan2026-06-25UIN SUNAN KALIJAGA YOGYAKARTA;FAKULTAS SYARIAH DAN HUKUMThesis
