D Deportation is a form of immigration action imposed on foreign nationals who commit immigration violations in a country. the case of cikal ramadhan, an indonesian citizen originally from binjai, is an example of repeated deportation. after being deported from cambodia in 2022, he returned to the country through unprocedural means and was deported again in 2024. the core issues are how the class i special immigration office for tpi soekarno-hatta plays a role in supervising the case of cikal ramadhan, who was previously deported from cambodia, and how coordination between indonesian representatives abroad and the directorate general of immigration is conducted in handling cases of indonesian citizens who have been deported. the research was conducted using a normative juridical legal research method, with secondary data supported by interviews with sources. the nature of the research is analytical descriptive, and conclusions were drawn using the deductive method. based on the research results, the class i special immigration office for tpi soekarno-hatta has not carried out supervision optimally because repatriation history is not automatically used as the basis for in-depth examination during the passport issuance or departure stages. coordination between the indonesian embassy in phnom penh and the directorate general of immigration runs effectively during the repatriation stage, but is not yet optimal at the post-deportation supervision stage because the data of repatriated indonesian citizens is not yet effectively integrated between institutions.
