Karakteristik Fisika Tanah pada Beberapa Tegakan di Sub DAS Petani Kabupaten Deli Serdang Sumatera Utara
ABSTRACT
Vidiya Novelin Asnan Lubis, researched “The Characteristics of Soil
Physics Stands of Plants’s in Petani Watershed Deli Serdang Regency North
Sumatera”. Surpervised by Prof. Dr. Ir. Abdul Rauf, MP. dan Ir. Bintang, MP.
It was aims to get the characteristics of soil physics in various land use in Petani
watershed. It was located at Buluh Awar Village Sibolangit Subdistrict Deli
Serdang Regency North Sumatera, Soil Physic Laboratory, Research and
Technology Laboratory Agriculture Faculty North Sumatra from March until
August 2015. It used descriptive method with field observation techniques. The
sampling techniques based on purposive sampling method with 4 treatments and
10 replications. The parameters measured was bulk density, soil porosity, soil
permeability, soil color, soil texture and soil water content. The results tested with
the T test standard 5%.
The results showed that only soil porosity’s under the stands of sugar
palm plants (65,578 %) significantly affected soil porosity’s under the stands of
forest (69,877 %). The other parameters like bulk density, soil permeability and
soil water content weren’t significantly affected about soil samples forest.

Vidiya Novelin Asnan Lubis, meneliti “Karakteristik Fisika Tanah pada
Beberapa Tegakan di Sub DAS Petani Kabupaten Deli Serdang Sumatera Utara”,
dibawah bimbingan Prof. Dr. Ir. Abdul Rauf, MP. dan Ir.Bintang, MP. Penelitian
bertujuan untuk mendapatkan karakteristik fisika tanah pada berbagai penggunaan
lahan di Sub DAS Petani. Lokasi penelitian di Desa Buluh Awar, Kecamatan
Sibolangit Kabupaten Deli Serdang Sumatera Utara, Laboratorium Fisika Tanah
dan Laboratorium Riset dan Teknologi Fakultas Pertanian Universitas Sumatera
Utara pada bulan Maret sampai dengan Agustus 2015 menggunakan metode
deskriptif dengan teknik observasi lapangan. Teknik sampling berdasarkan
metode purposive sampling dengan 4 perlakuan dan
10 ulangan. Parameter
yang diukur yaitu Kerapatan Isi, Porositas Tanah, Permeabilitas Tanah, Warna
Tanah, Tekstur Tanah dan Kadar Air Tanah diolah dengan uji T taraf 5%.
Hasil penelitian menunjukkan bahwa hanya parameter porositas tanah
tegakan tanaman aren (65,578 %) yang berbeda nyata terhadap porositas tanah
tegakan hutan (69,877 %). Parameter fisika tanah yang lain seperti kerapatan isi
(Bulk density), permeabilitas tanah dan kadar air tanah pada tegakan aren, durian
dan karet tidak berbeda nyata terhadap tegakan hutan.
