Introduction

The construction of the SUTET (Extra High Voltage Airway) infrastructure is a crucial step in electricity distribution, and its impact on the surrounding environment is a significant concern. Bulupayung Village, South Tapanuli, is one of the locations where SUTET is being constructed, making it essential to examine the condition of the land in the area. This study focuses on the physical properties of the soil and infiltration rates on various land cover around the SUTET building in Bulupayung Village, Sipirok District, South Tapanuli. The Philip method is used to analyze the data obtained.

Research Methods and Results Obtained

This study focuses on three types of land cover: horticultural fields, cocoa fields, and durian fields. The parameters measured include soil texture, water content, organic matter content, mass density, particle density, porosity, and cumulative infiltration. Infiltration measurements are carried out using a double ring infiltrometer for 180 minutes. The results showed that the highest infiltration rate was found in cocoa fields with the FP equation = 0.291984 + 0.77484.t-0,5 cm/minute. Followed by durian fields with the FP equation = 0.133504 + 0.33205.t-0,5 cm/minute. The lowest infiltration rate is found in the horticultural field with the FP equation = 0.10859 + 0.43584.t-0,5 cm/minute.

Analysis and Implications

A significant difference in infiltration rate between land cover indicates the effect of vegetation on the physical properties of the soil. Cocoa fields with tight vegetation and strong root systems can increase water infiltration into the soil. This is triggered by:

*** Increasing Porosity: ** The dense vegetation provides greater space between roots, thereby increasing the porosity of the soil and facilitating the flow of water. *** Decreased Mass Density: ** Plant roots help spoil the soil, thereby reducing mass density and increasing pore space that can be filled with water. *** Increasing the Content of Organic Matter: ** Fall leaves and other organic remnants under the cocoa canopy increase the content of soil organic matter. This organic matter increases soil aggregation and increases the ability of soil to hold water.

Conversely, horticultural fields with vegetation that are more rarely have a low infiltration rate. This is because vegetation is rarely unable to significantly increase the porosity of the soil, and the organic matter content is lower compared to cocoa fields.

Recommendations and Conclusions

The results of this study have important implications for land management around the SUTET building.

*** The Importance of Vegetation: ** It is necessary to preserve and increase vegetation around the SUTET building to increase the rate of water infiltration and reduce the potential for erosion. ** Land Cover Options: ** The use of plants with strong root systems such as cocoa, can be the right choice to improve the ability of the soil to hold water and prevent erosion. *** Soil Management: ** It is important to apply sustainable soil management methods, such as the use of organic fertilizer, plant rotation, and soil processing without processing, to improve the structure and ability of the soil in absorbing water.

This study shows that soil vegetation is a key factor that affects the rate of water infiltration. Therefore, proper land management is very important to preserve the environment and sustainability of SUTET infrastructure in Bulupayung Village.

Background and Literature Review

The construction of SUTET infrastructure has a significant impact on the environment, including the soil and water resources. The physical properties of the soil, such as texture, water content, and organic matter content, play a crucial role in determining the infiltration rate of water into the soil. Vegetation cover is also an important factor that affects the physical properties of the soil and infiltration rates.

Physical Properties of Soil

Soil texture, water content, and organic matter content are the most important physical properties of soil that affect infiltration rates. Soil texture refers to the proportion of sand, silt, and clay particles in the soil. Water content refers to the amount of water present in the soil, while organic matter content refers to the amount of organic matter present in the soil.

Vegetation Cover and Infiltration Rates

Vegetation cover is an important factor that affects infiltration rates. Vegetation with strong root systems, such as cocoa, can increase water infiltration into the soil by increasing porosity and decreasing mass density. Conversely, vegetation with weak root systems, such as horticultural fields, can decrease water infiltration into the soil by decreasing porosity and increasing mass density.

Methodology

This study uses the Philip method to analyze the data obtained. The Philip method is a widely used method for analyzing infiltration data. The method assumes that the infiltration rate is a function of time and can be described by a mathematical equation.

Data Collection

The data used in this study were collected from three types of land cover: horticultural fields, cocoa fields, and durian fields. The parameters measured include soil texture, water content, organic matter content, mass density, particle density, porosity, and cumulative infiltration. Infiltration measurements were carried out using a double ring infiltrometer for 180 minutes.

Results and Discussion

The results of this study showed that the highest infiltration rate was found in cocoa fields with the FP equation = 0.291984 + 0.77484.t-0,5 cm/minute. Followed by durian fields with the FP equation = 0.133504 + 0.33205.t-0,5 cm/minute. The lowest infiltration rate is found in the horticultural field with the FP equation = 0.10859 + 0.43584.t-0,5 cm/minute.
