Abstract
Penelitian ini bertujuan untuk merumuskan alokasi penggunaan lahan Kawasan Daerah Aliran Sungai (DAS) Serayu Hulu di Kecamatan Kejajar. Bererapa analisis yang digunakan adalah watershed analysis untuk menentukan delineasi wilayah studi; analisis Universal Soil Loss Equation (USLE) untuk memprediksi laju erosi per penggunaan lahan; dan analisis Linear Programming untuk mencari alokasi penggunaan lahan yang optimal dalam rangka menurunkan laju erosi yang terjadi. Adapun tujuan yang ingin dicapai adalah alokasi penggunaan lahan yang optimal dari 5 jenis penggunaan lahan yang teridentifikasi di wilayah studi yaitu penggunaan lahan hutan lindung, hutan produksi, permukiman, ladang, dan sungai. Hasil optimasi menunjukkan dalam rangka mengurangi laju erosi yang terjadi diperlukan penambahan luas pada dua penggunaan lahan yakni hutan lindung dan hutan produksi masing-masing sebesar 374,20 ha dan 788,73 ha. Luas penggunaan lahan ladang perlu dikurangi sebesar 1.170,82 ha. Sedangkan luas penggunaan lahan permukiman dan sungai tidak mengalami perubahan. Dari hasil optimasi, laju erosi dapat dikurangi sebesar 159.189,31 ton/tahun atau sebesar 19,58%.
