Design of soil and water conservation techniques to minimize soil erosion on degraded land in Samarinda Tenggarong Axis Road

Abstract

Abstract Soil conservation activities are aimed at tackling land degradation, especially soil erosion, which occurs rapidly. If there is human intervention, land will become more sensitive to the influence of water (rainfall) and gravitational forces. This study aimed to identify the types of erosion that occur on degraded land and design appropriate soil and water conservation techniques based on vegetative and physically degraded land conditions on the Samarinda-Tenggarong Axis road. The results of the documentation collected from each research site identified the type of erosion, and designed soil and water conservation techniques. This research is focused on the design referring to Permenhut P.04/Menhut-11/2011 and UU RI/37/2014. The results of this study showed that location 1 of the recommended technique is the vegetative technique and the manufacture of Water Sewerage, location 2 is the bench terrace technique, location 3 is the retaining wall technique, location 4 is the individual terrace technique, location 5 is the stone terrace/wall technique, location 6 is the stone terrace/wall technique, and location 7 is the garden terrace technique. The design of the soil and water conservation techniques recommended in this study is expected to have a positive effect on minimizing soil erosion on degraded land.
