Klasifikasi Tanah di Lereng Selatan Gunung Burni Telong Kecamatan Bukit Kabupaten Bener Meriah Provinsi Aceh
ABSTRAK
Penelitian survei bertujuan untuk mengetahui klasifikasi tanah di Lereng
Selatan Gunung Burni Telong. Penelitian ini dilakukan pada Februari –
September 2014 di Kecamatan Bukit, Kabupaten Bener Meriah, Provinsi Aceh.
Dua profil tanah sebagai pewakil diamati pada lereng tengah (Va.1.6.1t) dan
lereng bawah Gunung Burni Telong (Va.1.4.1t). Sampel tanah diambil dari setiap
horizon untuk dianalisis tekstur tanah, kerapatan isi, pH H2O, pH KCl, pH NaF,
Aldd, KTK, KB, C-Organik, retensi-P, Al-oksalat (Alo), Si-oksalat (Sio), dan
Fe-oksalat (Feo) di Laboratorium Riset dan Teknologi Fakultas Pertanian
Universitas Sumatera Utara, Medan dan Laboratorium Tanah Balai Penelitian
Tanah, Bogor.
Hasil pengamatan lapang dan analisis laboratorium menunjukkan bahwa
tanah pada lereng tengah (Va.1.6.1t) diklasifikasikan kedalam sub grup Humik
Psammentik Dystrudepts sedangkan lereng bawah (Va.1.4.1t) diklasifikasikan
kedalam sub grup Typic Hapludand menurut sistem klasifikasi Taksonomi Tanah

ABSTRACT
The survey research is aimed to know the classification of soils at south
slope of mount Burni Telong. This research had been conducted in in February –
September 2014 at Sub district Bukit, District Bener Meriah, Aceh Province. Two
selected pedons were observed at middle slop (Va.1.6.1t) and bottom slope
(Va.1.4.1t). Soil samples were taken from each horizon for analysis soil texture,
bulk density, pH H2O, pH KCl, pH NaF, Aldd, CEC, Base Saturation, Organic
content, P-retention, Al-oxalate extracted (Alo), Si- oxalate extracted (Sio), and
Fe- oxalate extracted (Feo) in Research and Technology Laboratory, Agricultural
Faculty of North Sumatera University, Medan and Soil Laboratory, Soil Research
Institute, Bogor.
The result of the observation and the analysis showed that the middle
slope soil (Va.1.6.1t) is classified into sub group Humic Psammentic Dystrudepts
however the bottom slope soil (Va.1.4.1t) is classified into sub group Typic
Hapludand according to Soil Taxonomy Twelfth Edition, 2014.
