Abstract

This study aims (1) to determine the ratio of the erosion value of the usle methods in the Lawo watershed (2) to plan soil and water conservation in the Lawo watershed. This research is based on mapping which is classified as non-experimental research using survey method. The erosion value was predicted using the Universal Soil Loss Equation (USLE) model. The results showed that land use in the Lawo watershed was secondary forest, plantation forest, dry land agriculture, dry land farming mixed with shrubs, shrubs, settlements and open land. The total erosion value for the USLE method is the average erosion that occurs. in the lawo river basin, namely 30948352.27 tonnes / year tonnes / year. Lawo watershed recovery plan in the form of land use patterns to reduce the rate of erosion, namely agroforestry dry land farming, while for settlements in the form of infiltration wells, enrichment of plants for plantation forest land use, refinement of bench terraces on paddy land use and terracing use accordingly the field, as well as reforestation and planting of land cover for the use of shrub land.

Abstract

Soil and Water Conservation is an effort to protect, restore, improve, and maintain the function of the land by the capabilities and allotment of land to support sustainable development and sustainable living. This study aims to identify and assess the proper use of soil and water conservation techniques applied by farmers based on the assessment guidelines for soil and water conservation techniques and their relationship with socioeconomic factors that influence the actions of Soil and Water Conservation. Methods of direct observation in the field both in the form of surveys and in the way of interviews with farmers who apply soil and water conservation techniques. Data collected from socioeconomic factors such as age, level of education, income, number of family dependents, and area of ​​arable land. The data is processed by contingency techniques then classified and tested in chi-square.The results of this study indicate that the application of soil and water conservation techniques in The Catchment area of Nanggala river in the form of vegetative methods is applied in the way of cover crops, yards, and mixed gardens, while mechanical methods in the form of bench terraces. The application of soil and water conservation techniques by farmers is 67.75% correct, 9.67% somewhat proper, and 22.58% incorrect. Soil and water conservation techniques do not have a real relationship with socioeconomic factors.
