POWER AND MADNESS: A FOUCAULDIAN ANALYSIS OF INSTITUTIONAL CONTROL IN SHUTTER ISLAND
Full text linkThis study examines Michel Foucault's theories on power and madness through the film Shutter Island, focusing on how institutional control shapes perceptions of sanity and insanity. Using Madness and Civilization as a theoretical framework, the research explores how psychiatric institutions define and regulate madness, creating "docile bodies" through surveillance and discipline. The data source consists of selected scenes from Shutter Island that illustrate institutional control mechanisms. The study employs qualitative methods, including scene analysis and dialogue transcription, to uncover the film's depiction of power dynamics. The findings reveal that the institution on Shutter Island functions as both a physical and psychological prison, using isolation, sedation, and psychological manipulation to maintain authority over patients. The narrative critiques the normalization and pathologization of madness, demonstrating how compliance with institutional norms is rewarded while deviation is punished. Authority figures, particularly doctors, play a central role in shaping patients' realities, exposing the oppressive nature of psychiatric institutions disguised as therapeutic environments. This study offers a contemporary application of Foucault’s theories, highlighting the ethical implications of power in mental health care.Penelitian ini bertujuan untuk mengkaji teori Michel Foucault tentang kekuasaan dan kegilaan melalui film Shutter Island. Fokusnya adalah pada bagaimana kontrol institusional membentuk persepsi tentang kewarasan dan ketidakwarasan. Dengan menggunakan Madness and Civilization karya Foucault sebagai kerangka dasar, penelitian ini mengeksplorasi bagaimana institusi sosial seperti fasilitas kesehatan mental mendefinisikan dan mengatur kegilaan, menciptakan "tubuh-tubuh patuh" melalui pengawasan dan disiplin. Penelitian ini menggunakan metode kualitatif, termasuk analisis mendalam terhadap adegan dan transkripsi dialog, untuk mengungkap bagaimana film tersebut menggambarkan dinamika kekuasaan institusional. Film ini dianalisis sebagai representasi modern dari Panopticon Foucault, di mana pengawasan yang terus-menerus menyebabkan pasien mengatur diri sendiri dan menyesuaikan diri dengan norma-norma institusional. Hasil utama menunjukkan bahwa institusi di Shutter Island berfungsi sebagai penjara fisik sekaligus psikologis, menggunakan isolasi, sedasi, dan manipulasi psikologis untuk mempertahankan otoritas atas pasien. Narasi film mengkritik normalisasi dan patologisasi kegilaan, menunjukkan bagaimana kepatuhan terhadap standar institusional dihargai, sedangkan penyimpangan dihukum. Tokoh otoritas, terutama dokter, memainkan peran sentral dalam membentuk realitas dan identitas pasien, mengungkap sifat menindas dari institusi psikiatri yang terselubung dalam lingkungan terapeutik. Penelitian ini memberikan aplikasi kontemporer terhadap teori Foucault, menyoroti implikasi etis dari kekuasaan dalam perawatan kesehatan mental
