dc.description.abstract | Produktivitas lahan selain faktor iklim, pengairan dan hama penyakit juga
ditentukan oleh kualitas lahan. Tanah sawah memiliki sifat karakteristik dan tingkat
kesuburan yang berbeda dengan jenis lahan pertanian lainnya. Tanah sawah
memiliki peruntukan pada tanaman pangan khususnya tanaman padi serta
penggunaan air dengan jumlah yang banyak dibandingkan tanah yang tidak
disawahkan serta sangat bervariatif bisa ditanaminya. Keanekaragaman
karakteristik sifat tanah sawah perlu dievaluasi untuk mengetahui kualitas dan
tingkat kesuburannya. Penelitian ini bertujuan mengevaluasi karakteristik sifat fisik,
kimia, dan biologi tanah sawah, menetapkan Indeks Kualitas Tanah (IKT) pada
tanah sawah serta memberikan solusi untuk meningkatkan produksi padi pada tanah
sawah. Penelitian dilaksanakan di Desa Ramasari, Kecamatan Haurwangi,
Kabupaten Cianjur, Provinsi Jawa Bawat. Analisis indeks kualitas tanah
berdasarkan metode Lal (1994) menggunakan Minimum Data Set (MDS) yang
menjadi penciri kunci dari kualitas tanah di wilayah tropis dengan bobot (weighted
coefisient) yang sama setiap parameter yaitu 10%. Masing-masing indikator sifat
fisik dan kimia diberi skor antara 0-5 dan disesuaikan dengan kriteria indeks
kualitas tanah. Berdasarkan hasil penelitian didapatkan bahwa parameter sifat fisik
dan kimia tanah yang ditetapkan sebagai Minimum Data Set (MDS) tekstur, bobot
isi, porositas, C-organik, N-total, P-tersedia (P2O5), Kalium dapat ditukar (K-dd),
Kapasitas Tukar Kation (KTK), dan Kejenuhan Basa (KB). Berdasarkan hasil
penelitian menunjukkan lokasi penelitian bertekstur klei yang masuk kedalam
kategori sedang. Bobot isi berkisar pada 0.87 – 1.1g/cm3
. Porositas berkisar pada
37.63 – 57.31%. Kadar C-organik masuk kedalam katagori sedang hingga baik. N Total berkisar 0.18-0.21% masuk relatif tergolong buruk. P-tersedia, K-dd masuk
dalam katagori buruk hingga sangat buruk. KTK dan KB relatif tinggi. Total mikrob
berkisar 19.5-24.5 (x105 CFU g-1
). Respirasi tanah memiliki nilai pada rentang 6,26
- 9,69 mg CO2/kg tanah/hari . Nilai IKT berkisar 28 – 32, yang masuk kategori
sedang dan baik. Hasil produksi padi di lokasi penelitian belum mencapai
produktivitas maksimum dari setiap verietasnya. Nilai indeks kualitas tanah belum
mencapai katagori yang sangat memuaskan dikarenakan selain total skornya yang
masih belum tinggi, juga masih ada parameter yang menjadi faktor pembatas yang
memiliki skor yang sama atau lebih rendah dari dua, yaitu, N-total, P-tersedia dan
K-tersedia serta porositas. | |
dc.description.abstract | Apart from climate, irrigation and pest and disease factors, land
productivity is also determined by land quality. Rice fields have different
characteristics and fertility levels from other types of agricultural land. Paddy fields
are designated for food crops, especially rice, and use large amounts of water
compared to land that is not cultivated and can be planted with a lot of variety. The
diversity of characteristics of paddy field soil needs to be evaluated to determine its
quality and level of fertility. This research aims to evaluate the physical, chemical
and biological characteristics of rice field soil, determine the Soil Quality Index
(IKT) on rice field soil and provide solutions to increase rice production on rice
field soil. The research was carried out in Ramasari Village, Haurwangi District,
Cianjur Regency, Java Bawat Province. Soil quality index analysis based on the Lal
(1994) method uses the Minimum Data Set (MDS) which is a key characteristic of
soil quality in tropical regions with the same weighted coefficient for each
parameter, namely 10%. Each indicator of physical and chemical properties is given
a score between 0-5 and adjusted to the soil quality index criteria. Based on the
research results, it was found that the parameters of the physical and chemical
properties of the soil were determined as Minimum Data Set (MDS), texture, unit
weight, porosity, C-organic, N-total, P-available (P2O5), exchangeable potassium
(K-dd) , Cation Exchange Capacity (CEC), and Base Saturation (KB). Based on the
research results, it shows that the research location has a smooth texture which is
included in the medium category. Fill weight ranges from 0.87 – 1.1g/cm3
. Porosity
ranges from 37.63 – 57.31%. Organic C levels are in the moderate to good category.
N-Total ranges from 0.18-0.21% which is relatively bad. P-available, K-dd is in the
bad to very bad category. CEC and KB are relatively high. Total microbes ranged
from 19.5-24.5 (x105 CFU g-1
). Soil respiration has a value in the range of 6.26 -
9.69 mg CO2/kg soil/day. The IKT value ranges from 28 – 32, which is in the
medium and good category. Rice production results at the research location have
not yet reached maximum productivity for each variety. The soil quality index value
has not yet reached a very satisfactory category because apart from the total score
which is still not high, there are also parameters which are limiting factors which
have the same or lower score of the two, namely, N-total, P-available and K available as well as porosity. | |
