Abstract

Air tanah adalah sumber air yang sangat penting untuk keperluan domestik, pertanian, maupun industri. Konsumsi air tanah terus mengalami peningkatan seiring dengan perkembangan perkotaan. Hal tersebut ditandai dengan pesatnya pertumbuhan penduduk dan peningkatan aktivitas manusia yang membutuhkan sumber daya air. Provinsi DIY merupakan salah satu provinsi di Indonesia yang wilayahnya memiliki akuifer yang cukup besar dengan sumber daya air tanah yang tinggi. Namun, masih terdapat permasalahan terkait potensi air tanah, yakni adanya penurunan muka air tanah dan pencemaran air tanah. Pemetaan potensi air tanah ini bertujuan untuk mengevaluasi penggunaan sumberdaya air tanah di Provinsi DIY. Penelitian ini memanfaatkan bidang kajian Sistem Informasi Geografis dengan metode Analytical Hierarchy Process (AHP) menggunakan parameter-parameter air tanah, yaitu curah hujan, litologi, geomorfologi, kelerengan, tutupan lahan, NDVI, dan Topographic Wetness Index (TWI). Hasil pengolahan Analytical Hierachy Process (AHP) pada identifikasi potensi air tanah Provinsi DIY menghasilkan klasifikasi potensi air tanah sangat rendah dengan luas 0,651 km², rendah seluas 0,783 km², sedang seluas 0,718 km², tinggi dengan luas 0,471 km², dan sangat tinggi dengan luas 0,528 km².
