Analisis kadar air, bobot isi dan porositas tanah pada beberapa penggunaan lahan
Abstrak
Penelitian ini bertujuan untuk menentukan kadar air, bobot isi dan porositas tanah pada penggunaan lahan tegalan/lading, kebun campuran, perkebunan teh, semak belukar dan hutan tanaman di DAS Ciliwung Hulu. Penelitian dimulai dari survei pendahuluan di lapangan untuk menentukan lokasi serta melakukan penentuan titik-titik pengamatan pada setiap penggunaan lahan. Pengambilan sampel tanah dilakukan untuk analisis kadar air, bobot isi dan porositas tanah. Hasil penelitian menunjukkan bahwa penggunaan lahan hutan tanaman merupakan penggunaan lahan yang baik dengan nilai kadar air tanah yang tinggi yaitu sebesar 85,88%, bobot isi tanah 0,59 g/cm3 dan porositas tanah 77,78% yang menunjukkan bahwa lahan hutan tanaman porous.
