Songkok Celleng is the mention of headgear for men in terms of the Madurese community or often referred to as a cap and kopyah. The head covering or known as Songkok Celleng is a complementary part in dressing for the santri (student in Islamic Boarding School), traditional clothing in the community to clothing for bureaucrats who have an implicit significance in its use. In this scientific work, the writer uses a semiotic qualitative method according to Charles Sanders Pierce who specifically describes that the sign is able to represent something else. In addition, Pierce also defines the sign as something that can not be separated from the object of reference and understanding of the subject of signs with trichotomy: representamen, interpretants and objects. From the research conducted, the conclusions that can be shown by the author are: (1) Songkok celleng (representamen) is a santri identity containing philosophical meaning of obedience or submission (interpretant) in the form of a head covering (object). (2) Songkok celleng is always present with the spirit of nationalism introduced by the First President of Indonesia (Sukarno) that Songkok Celleng is a national identity also strengthened by government regulations issued during the Soekarno administration.
