Evaluasi Laju Infiltrasi pada Daerah Rawan Banjir di Kecamatan Lhoksukon Kabupaten Aceh Utara

Abstrak. Infiltrasi tanah adalah proses masuknya air secara vertikal ke dalam melalui permukaan tanah. Proses infiltrasi dapat membantu memenuhi kebetuhan terhadap dan mengurangi terjadinya erosi banjir. dipengaruhi oleh beberapa sifat yaitu tekstur tanah, C-organik, porositas, bulk density, permeabilitas kemantapan agregat. Penelitian ini dilakukan di Kecamatan Lhoksukon Kabupaten Aceh Utara pada penggunaan lahan pemukiman, sawah, kebun campuran perkebunan kelapa sawit dengan mengukur nilai laju lapangan menilai sifat-sifat yang mempengaruhi infiltasi. Hasil penelitian menunjukkan bahwa infiltasi daerah rawan banjir mendapatkan klasifikasi sangat lambat, lambat agak lambat. Nilai terdapat titik TR4-Kelapa Sawit, R3-Kebun Campuran SR3-Pemukiman, TR2-Sawah, R1- Pemukiman SR2-Sawah TR1-Kebun Campuran, R3-Pemukiman, R2-Sawah, R4-Kelapa Sawit SR2-Kebun Campuran. Adapun faktor-faktor tekstur, C–organik porositas tanah.Evaluation of Infiltration Rates in Flood Prone Areas District, North RegencyAbstract. Soil infiltration is the process vertical entry water into soil through surface. The can help meet need for and reduce occurrence erosion flooding. influenced by several properties, namely texture, organic C, porosity, permeability, aggregate stability. This research was conducted Regency on residential land use, paddy, mixed gardens, oil palm plantations measuring value rate field assessing properties that affect infiltration. results this study indicate flood-prone areas District classified as very slow, rather slow. slow at points TR4-Oil Palm, R3-Mixed Gardens, SR3-Settlements, TR2-Paddy, Settlements, SR2-Paddy, point TR1-Mixed R3-Settlements, R2-Paddy, R4-Oil Palm SR2-Mixed Gardens. factors are C-organic, porosity.
