Sulistyaningrum, Dina (2014) Analisis Nilai Indeks Erodibilitas Tanah Di Desa Sukoanyar, Kecamatan Pakis, Kabupaten Malang. Sarjana thesis, Universitas Brawijaya.
Abstract
Wilayah Desa Sukoanyar terletak di Kecamatan Pakis Kabupaten Malang. Mata pencaharian penduduk bertumpu kepada sektor pertanian. Untuk meningkatkan pendapatan penduduk maka dilakukan usaha ekstensifikasi lahan pertanian yang dapat membawa dampak erosi. Oleh karena itu, perlu dilakukan penelitian untuk memprediksi besarnya tingkat erodibilitas tanah pada Desa Sukoanyar tersebut. Sampel tanah diambil di wilayah Desa Sukoanyar, Kecamatan Pakis, Kabupaten Malang yang berasal dari 3 lokasi yang berbeda yang telah dikompositkan. Selanjutnya, dilakukan analisis sifat-sifat tanah yang meliputi tekstur, struktur, permeabilitas, dan bahan organik tanah. Selanjutnya, dilakukan pengeplotan data hasil analisis tersebut pada nomograf Wischmeier (1971). Kemudian, membandingkan hasil dari nilai indeks erodibilitas tanah (K) tersebut berdasarkan tabel klasifikasi kelas erodibilitas tanah di Indonesia. Berdasarkan hasil penelitian, lokasi 1 (7o5920" LS, 112o4430" BT) memiliki tekstur tanah lempung berdebu, struktur tanah granuler sangat halus, permeabilitas tanah 22,9 cm/jam, bahan organik tanah 1,11%, nilai K 0,678. Lokasi 2 (7o5911" LS, 112o4430" BT) memiliki tekstur tanah lempung, struktur tanah granuler sangat halus, permeabilitas tanah 16,8 cm/jam, bahan organik tanah 1,43%, nilai K 0,559. Selanjutnya, lokasi 3 (7o5855" LS, 112o4435" BT) memiliki tekstur tanah lempung berliat, struktur tanah granuler sangat halus, permeabilitas tanah 8,2 cm/jam, bahan organik tanah 1,63%, nilai K 0,439. Sehingga, ketiga lokasi tersebut termasuk dalam tingkat erodibilitas tanah yang sangat tinggi.
English Abstract
Sukoanyar Village is located in Pakis Subdistrict, Malang Regency. Livelihoods of the population relies on agriculture. To increase their income then made the agricultural land extending which can cause the effects of erosion. Therefore, research isneeded to predict the level of soil erodibility on the Sukoanyar village. Soil samples were taken in Sukoanyar Village, Pakis Subdistrict, Malang Regency from 3 different location that have been composited. Furthermore, analize the soil properties like texture, structure, permeability, and soil organic matter. Furthermore, the analysis of data entering in the nomograph Wischmeier (1971). Then, compare the results of soil erodibility index (K) is based on the table of soil erodibility class in Indonesian. Based on the result of research, location 1 (7o5920 "LS, 112o4430" BT) has silty clay of soil texture, the soil structure is very fine granular (crumbs), the soil permeability is 22.9 cm/h, the soil organic matter is 1.11%, and the value of K is 0.678. Then, location 2 (7o5911 "LS, 112o4430" BT) has clay of soil texture, the soil structure is very fine granular (crumb), the soil permeability is 16.8 cm/h, the soil organic matter is 1.43%, and the value of K is 0,559. Furthermore, location 3 (7o5855 "LS, 112o4435" BT) has clay loam of soil texture, the soil structure is very fine granular (crumbs), the soil permeability is 38.2 cm/h, the soil organic matter is 1.63 %, and the K value is 0.439. Thus, those three locations included in the very high rate of soil erodibility.
