چکیده
The Bale River Sub Basin is located in Tulungrejo Village, Gandusari District, Blitar Regency, on territory with undulating topography and at an elevation of 519 to 846 meters above sea level, steep extremely slopes. majority the sub-watershed area's land use, notably forests, has been transformed into agricultural or mixed gardens, where conversion carried out without conservation measures under adverse cover conditions. Land use that does not comply requirements exposes erosion, As a result, goal this research forecast quantity erosion sub-watershed. This study employed literature review field survey, data collected form primary secondary sources. MUSLE (Modified Universal Soil Loss Equation) approach was used for analysis estimate amount area. According findings study, 18 units, unit 4 having highest value 647,99 tons per hectare year. Vq factor 2.322,76 m3, K 0.50, LS 1.7, CP 0.60 residential no activities. Meanwhile, 17 had lowest 1,09 686,05 0.30, 3.8, 0.02 forest methods such as bunds reinforcing grass.
 Daerah Aliran Sungai berada di Desa Tulungrejo, Kecamatan Gandusari, Kabupaten yang memiliki lahan dengan topografi bergelombang dan pada ketinggian antara 519–846 mdpl didominasi kelerengan curam hingga sangat curam. Penggunaan sebagian besar wilayah sub DAS Bale, yaitu berupa hutan telah banyak berubah menjadi pertanian atau kebun campuran. Dimana alih fungsi tersebut dilakukan tanpa tindakan konservasi kondisi penutup kurang baik. Pemanfaatan tidak sesuai ketentuan akan berakibat kerentanan terhadap kejadian erosi, ditambah kemiringan lereng Dengan demikian, tujuan dari kajian ini adalah untuk menduga/prediksi besaran erosi Bale. Metode digunakan dalam penelitian studi literatur survei lapangan primer sekunder. Analisis menggunakan metode pendugaan besarnya kajian. Hasil ini, terdapat nilai terbesar sebesar ton/ha/tahun. Satuan 4, faktor 0,50, 1,7 0,60 penggunaan permukiman adanya upaya konservasi. Sementara itu, terkecil Nilai 0,30, 3,8, 0,02 serta guludan rumput penguat.

A nonparametric/parametric analysis of the Universal Soil Loss Equation
Due to its modest data demands and transparent model structure, the Universal Soil Loss Equation (USLE) remains the most popular tool for water erosion hazard assessment. However, the model has several shortcomings, two of which are likely to have prominent implications for the model results. First, the mathematical form of the USLE, the multiplication of six factors, easily leads to large erro...

Modified Universal Soil Loss Equation (MUSLE) is one of soil loss estimation models which has been developed based on the runoff characteristics in the event scale. However, it needs to be evaluated in the plot scale for the semi-arid rainfall events. With this aim, a field study was designed using twenty one plots. Runoff and soil loss were measured using 5-min samples under seven rainfall int...
