Abstract
Perubahan penggunaan lahan dari ruang terbuka hijau (RTH), tambak, rawa dan kawasan lain yang mampu menampung air menjadi permukiman akan meningkatkan air limpasanyang ditampung kawasan Pantai Timur Surabaya. Jika penggunaan lahan tidak dikendalikan, konsekuensinya adalah semakin berkurangnya kemampuan penampungan air di kawasan konservasi. Untuk mencapai tujuan daripenelitianini, maka dilakukan tiga tahap analisis. Tahap pertama, faktor-faktor yang mempengaruhi dianalisis dengan deskriptif kualitatif. Tahap kedua, faktor-faktor digunakan untuk menentukan mintakat berdasarkan kemampuan penampungan air dengan analisis weighted overlay. Tahap terakhir, arahan pengendalian dirumuskan dengan analisis Delphi berdasarkan mintakat kemampuan penampungan air. Arahan pengendalian penggunaan lahan dirumuskan berdasarkan mintakat zona kemampuan penampungan air tinggi dan rendah. Hasil arahan pengendalian zona penampungan air tinggi fokus pada menambah hutan mangrove di kawasan konservasi dan normalisasi sungai yang mengalami penyempitan akibat okupansi masyarakat. Sedangkan pada zona penampungan air rendah, arahan pengendalian fokus pada melarang reklamasi ilegal dan melarang perubahan lahan tambak. Arahan ini dimaksudkan agar fungsi kawasan PantaiTimur Surabaya sebagai kawasan penampungan air tetap terjaga
