Abstract
Tanah menjadi salah satu aspek penting bagi kehidupan. Kemampuan suatu tanah
dalam menjalankan fungsinya dapat menggambarkan kualitas dari suatu tanah.
Kualitas tersebut dapat meningkat maupun menurun selama faktor inherent dan
dinamis berlangsung. Penelitian ini dilakukan untuk mengetahui karakteristik, indeks
kualitas tanah, serta sebarannya pada berbagai penggunaan lahan serta kemiringan
lereng di Dusun Ngelo Kenongo, Desa Monggol, Kecamatan Saptosari, Kabupaten
Gunungkidul. Kualitas tanah ditentukan dengan perhitungan Indeks Kualitas Tanah
(IKT) yang dihitung dengan menggunakan kriteria Mausbach dan Seybold (1998),
yang disesuaikan dengan kondisi lapangan. Sampel tanah diambil berdasarkan satuan
peta lahan yang merupakan overlay dari peta penggunaan lahan dan peta kemiringan
lereng. Sifat tanah yang diamati yaitu tekstur tanah, berat volume, berat jenis,
porositas, pH aktual, C-Organik, N total, P tersedia, K tersedia, kedalaman akar, dan
jumlah mikroba. Berdasarkah hasil penelitian didapatkan Indeks Kualitas Tanah
(IKT) dengan kriteria baik (7,69 Ha atau 13,56% ) pada satuan lahan Tegalan (Datar)
dan Sawah Tadah Hujan (Datar); kriteria sedang (37,09 Ha atau 65,84%) pada satuan
lahan Sawah Tadah Hujan (Landai), Tegalan (Landai), Tegalan (Agak Curam); serta
kriteria rendah (5,95 Ha atau 10,56%) pada satuan lahan Sawah Irigasi PDAM
(Datar). Peta sebaran kualitas tanah bertujuan dapat memberikan informasi mengenai
sebaran kualitas tanah di lokasi penelitian.

ABSTRACT
Soil is an important aspect of life. The capability of soil to performed soil
functions was illustrated by soil quality. The quality of soil might be increased or
decreased during inherent and dynamics factor were occured. This research were to
sudy to know the characteristic of soil, Index of Soil Quality, and distribution of soil
quality on different land uses and slopes in Ngelo Kenongo, Monggol Village,
Saptosari District, Gunungkidul Regency. The soil quality were carried out with
Index of Soil Quality assessment by criteria of Mausbach and Seybold (1998). The
soil samples were taken based on land map system which was overlayed from land
uses and slopes map, and samples were observed: texture, bulk density, pH(H2O),
porosity, C-Organic, N-Total, P2O5, K2O, root depth, and total of microbes. The
result showed that index of soil quality was on land maps unit of Field (Gently
Sloping) and Rainfed Lowland Rice (Gently Sloping) better condition (7,69 Ha or
13,56% ); Rainfed Lowland Rice (Strongly Sloping), Field (Strongly Sloping), Field
(Moderately sloping) moderately condition (37,09 Ha or 65,84%); and soil quality
index of Irrigated Rice by PDAM (Gently Sloping) low condition (5,95 Ha or
10,56%). Maps of distribution soil quality was purposed to provide the information
about distribution of soil quality on the location.
