| Summary: | Cilembu sweet potato, a primary agricultural product of Cilembu Village, exhibits
significant economic potential. This is evident in the consistently increasing
market demand for this commodity. However, productivity fluctuations due to
factors such as weather, rainfall, seed quality, cultivation practices, and soil
degradation hinder efforts to meet market demands. Geophysical methods,
renowned for their non-destructive nature, have been extensively employed in
characterizing soil structures. This study utilizes Seismic Refraction Tomography
(SRT) and Electrical Resistivity Tomography (ERT) to investigate soil properties.
The resulting Vp and resistivity models reveal distinct soil layer responses to
seismic and electrical signals, enabling identification of soil horizons. Horizon A,
characterized by Vp values ranging from 200 to 400 m/s and resistivity values
between 800 and 1000 ?m, is determined to exist at depths of 0-100 cm. Horizon
B exhibits Vp values of 400-600 m/s and resistivity values of 400-800 ?m. Model
validation was conducted through test pit at multiple sites within the study area. |
