dc.description.abstract | Tanah sawah dapat mengalami penurunan kualitas tanah dan produktivitas
akibat penggenangan dan pemberian pupuk anorganik secara terus menerus. Rotasi
tanaman antara padi dengan palawija dapat menjadi alternatif dalam
mempertahankan kesuburan lahan, produktivitas dan perekonomian petani.
Karakteristik dan kualitas tanah penting dalam pengembangan pertanian. Kualitas
tanah diukur dengan indikator kualitas tanah, salah satu indikatornya yaitu sifat
fisik tanah. Penelitian ini bertujuan mengkaji karakteristik sifat fisik tanah sawah
dan sifat fisik tanah yang berpengaruh terhadap Indeks Kualitas Fisik Tanah (IKFT),
serta mengetahui IKFT dan potensi tanah sawah pasca panen untuk penanaman
palawija di Kecamatan Sukaresmi, Kabupaten Cianjur. Metode yang digunakan
yaitu PCA (Principal Component Analysis) untuk memilih MDS (Minimum Data
Set) dari indikator sifat fisik tanah yang mewakili fungsi tanah. Hasil penelitian
menunjukkan lokasi penelitian memiliki karakteristik tanah bertekstur lempung
berpasir, lempung, lempung liat berpasir dan lempung berliat. Bobot isi berkisar
0,67-0,99 g/cm3
. Permeabilitas semua petak sawah > 12 cm/jam, pori drainase cepat
dan pori drainase lambat berkisar 2,66-23,11% dan 1,17-33,66%. Air tersedia
berada pada rentang 16,61-52,91%. Sifat fisik yang paling berpengaruh terhadap
indeks kualitas fisik tanah adalah tekstur, pori drainase lambat, bobot isi dan
permeabilitas. Nilai IKFT pada lokasi penelitian berada pada kisaran 2,80-4,50
dengan kategori agak buruk, sedang, agak baik dan baik. Lokasi penelitian memiliki
indeks kualitas fisik tanah yang didominasi kategori agak baik. Hasil analisis
karakteristik sifat fisik dan IKFT pada lokasi penelitian cukup sesuai dengan
pengembangan tanaman palawija, untuk IKFT kategori agak buruk dan sedang
dapat ditingkatkan dengan pemberian bahan organik. | id |
dc.description.abstract | Paddy fields can experience a decrease in soil quality and productivity due to
the continuous use and application of inorganic fertilizers. Crop rotation between
rice and crops can be an alternative to maintain land fertility, productivity, and the
economy of the farmers. Soil characteristics and quality are important in agriculture
development. Soil quality is measured by soil quality indicators, one of the
indicators is the physical properties of the soil. This study aims to examine the
characteristics of the physical properties of paddy soil, determine the soil physical
properties that have the most influence on the soil physical quality index (SPQI),
determine the SPQI, and determine the potential of post-harvest paddy soil for crops
in Sukaresmi District, Cianjur regency. The method used is PCA (Principal
Component Analysis) to select the MDS (Minimum Data Set) of soil physical
properties indicators that represent soil function. The results showed that the study
site has the characteristics of textured soil sandy loam, loam, sandy clay loam, and
clay loam. The bulk density is between 0.67-0.99 g/cm3
. The permeability of all
rice plots > 12 cm/h, fast drainage pores, and slow drainage pores ranged from 2,66-
23,11% and 1,17-33,66%. Available Water Capacity (AWC) is in the range of
16,61-52,91%. Physical properties that most affect the physical quality index of soil
are texture, slow drainage pores, bulk density, and permeability. SPQI value at the
study site is in the range of 2,80-4,50 with the category of rather low, moderate,
rather high, and high. The research location has a soil physical quality index that is
dominated by the rather high category. The results of the analysis of the
characteristics of physical properties and SPQI at the research site are quite in
accordance with the development of crops, for the SPQI category rather low and
moderate can be improved by the provision of organic matter. | id |
