ABSTRAK
Daerah Aliran Sungai Tambakbayan telah terjadi perubahan, berdasarkan data penggunaan lahan tahun 2006 dan tahun 2017. Perubahan yang terjadi berupa meningkatnya lahan terbangun dan berkurangnya lahan bervegetasi. Perubahan penggunaan lahan yang terjadi dapat mengakibatkan perubahan respon DAS yang dikuantifikasikan dalam bentuk koefisien aliran. Tujuan penelitian adalah mengevaluasi perubahan penggunaan lahan daerah penelitian dari tahun 2006 dan 2017, kaitannya dengan koefisien aliran. Metode yang digunakan adalah deskriptif kuantitatif berdasarkan studi pustaka dan perhitungan. Data sekunder yang digunakan adalah Peta Rupa Bumi Digital Indonesia Tahun 2006 dan 2017, Citra SRTM DAS Tambakbayan, Jenis Tanah DAS Tambakbayan, dan Jaringan Drainase DAS Tambakbayan. Perubahan penggunaan lahan akibat perkembangan wilayah, mengakibatkan peningkatan koefisien aliran pada tahun 2017 apabila dibandingkan dengan koefisien aliran pada tahun 2006.
