Assessing engineering geology characteristics for sustainable land use in Cucukan Village, Indonesia.

This study aimed to evaluate the suitability of land use in Cucukan Village, Prambanan, Klaten, by assessing its engineering geology characteristics. The investigation used the engineering geology mapping method based on secondary data and primary data collection through mapping surveys and observations. Further research was conducted to gather primary data, including geological investigations of surface and near-surface engineering, groundwater conditions, morphological conditions, and soil shear strength testing using the Dynamic Cone Penetrometer (DCP). The results showed that the groundwater level in Cucukan Village was dominant at 1.5 m - 2 m and was the free aquifer type with sandy constituent material above the young Merapi deposit. The rock units in Cucukan Village were classified into three types: sandy silt alluvial deposits, silty clay alluvial deposits, and sand alluvial deposits. The implications of these findings are that they provide valuable information for evaluating the suitability of land use in Cucukan Village, particularly for residential land development, which can have a significant impact on the groundwater table depth. Further research is needed to expand on these findings and to support future land development decisions. [ABSTRACT FROM AUTHOR]
