Abstract: The writing will reveal the relation of knowledge and power by taking the case of Sheikh Siti Jenar. The focus is on "aspects of thinking" that influence behavior. First, The problem sub-formulation, what is Sufi Siti Jenar thinking? Second, how does the relation of Siti Jenar's teachings dominate the body of its adherents to become its socio-political movement? Third, how is the practice of the power of walisongo knowledge in framing the truth of the teachings which has an effect on the marginalization of the Siti Jenar group?To do that, the writer will use a critical discourse analysis approach by utilizing his geneology theory Michel Foucault. The results of the discussion can be concluded are first, Sufism of Sufi Siti Jenar has the effect of liberation from humans themselves on the one hand, and has a deconstructive dimension to the meaning of power when placed in a socio-political space. Second, the form of mastery of his body is the birth of the perspective of the separation of religion and politics. However, because this thought was present at a time when the community did not yet have a referential awareness about secularization, the phenomenon of Siti Jenar and her followers was considered a rebel. Third, the locus of shari'ah walisongo actually makes Islam as something formalist. Formally, is an Islamic kingdom based on sharia enforcement itself. This makes the conflict of knowledge between sharia and Sufism. The clash is not only about interests but also because the basic character of the two sciences is indeed different and guides the behavior of adherents differently.??????? : ???? ????? ??? ??????? ????? ?? ???? ??????? ???????? ??? ??? ???? ????. ????? ????? ??? ??????? ???

Abstrak: Tulisan akan mengungkap relasi pengetahuan dan kekuasan dengan mengambil kasus Syekh Siti Jenar. Fokusnya pada ?aspek pemikiran? yang berpengaruh terhadap perilaku. Sub-rumusan masalahnya adalah pertama, bagaimana pemikiran tasawuf Siti Jenar? Kedua, bagaimana relasi ajaran Siti Jenar menguasai tubuh para penganutnya hingga menjadi gerak sosial politiknya? ketiga, bagaimana praktek kuasa pengetahuan walisongo dalam membingkai kebenaran ajaranya yang berefek pada marginalisasi kelompok Siti Jenar?. Untuk mengkerangkai pembahasan tersebut, penulis akan menggunakan pendekatan analisis wacana kritis dengan memanfaatkan teori geneologinya Michel Foucault. Hasil pembahasanya bisa disimpulkan pertama Pemikiran tasawuf Siti Jenar berdampak liberasi dari manusia itu sendiri di satu sisi, dan berdimensi dekonstrukstif pada makna kekuasaan bila diletakkan dalam ruang sosio-politik. Kedua, bentuk dari penguasaan tubuhnya adalah lahirnya perspektif pemisahan agama dan politik. Namun karena pemikiran ini hadir pada masa dimana masyarakat waktu itu belum mempunyai kesadaran referensial tentang sekularisasi, maka fenomena Siti Jenar dan pengikutnya dianggap sebagai pemberontak. Ketiga, lokus syari?ah walisongo justru menjadikan Islam sebagai sesuatu yang formalis. Bentuk formanyal adalah kerajaan Islam berbasis penegakan syariah itu sendiri. Hal ini menjadikan benturan pengetahuan antara syariah dengan tasawuf. Benturan itu bukan hanya adanya kepentingan tapi karena karakter dasar dari kedua ilmu itu memang berbeda dan menuntun perilaku penganutnya secara berbeda pula.
