Abstract

Penelitian ini bertujuan untuk menduga potensi air tanah di daerah rawan air dengan pendekatan Sistem Informasi Geografis (SIG) dan Analisis Multi Kriteria (MCA). Studi ini dilakukan di Kabupaten Tuban dengan mempertimbangkan berbagai parameter geospasial, seperti kemiringan lereng, jenis tanah, kondisi geologi, indeks vegetasi (NDVI), tutupan lahan, curah hujan, dan densitas drainase. Data yang digunakan meliputi DEMNAS, peta geologi, peta jenis tanah, serta data curah hujan dari BMKG. Hasil analisis menunjukkan bahwa potensi air tanah di Kabupaten Tuban berkisar antara kategori sedang hingga tinggi. Faktor utama yang mendukung potensi air tanah tinggi meliputi kemiringan lereng landai (0–5%), jenis tanah berpasir, struktur geologi berupa batu gamping dan endapan aluvium, tutupan lahan dominan berupa agrikultur dan hutan, serta curah hujan tinggi (>1.000 mm/tahun). Kecamatan dengan potensi air tanah tinggi antara lain Montong, Merakurak, Semanding, Rengel, dan Plumpang. Penelitian ini menegaskan bahwa metode SIG dan MCA efektif dalam mengidentifikasi potensi air tanah berdasarkan parameter geospasial. Hasil studi ini dapat digunakan sebagai referensi dalam perencanaan pengelolaan sumber daya air tanah serta mitigasi kekurangan air di daerah rawan.
