Abstract

Along with landform development, the soil on a landform also undergoes development characterized by various changes in physical and chemical characteristics. In this paper, we present the results of an investigating in to the physical and chemical characteristics of the soil in the paleochannel. The study was conducted in the Grabag-Pringsurat area where there are paleochannels with Pleistocene-aged materials. The study implemented the synthetic soil survey method. Nine paleochannels were selected as samples for observation. The data was then analyzed descriptively. There are two significant findings in this study. First, the physical properties of the soil are characterized by a dark color, fine-loamy texture, structural arrangement with strong aggregates, and strong consistency. In contrast, the chemical properties are characterized by acidic soil reactions. Second, soil properties are more developed in paleochannels filled with older materials. Overall, this study provides alternative information that reinforces the concept of soil development as an integral part of landform development.

Abstract

The Great Acceleration since the mid-20th century, resulting from the dominance of anthropogenic activities on Earth, has had a significant impact on the environment, including geomorphological evolution. This paper aims to investigate the Anthropocene-geomorphological evolution in the outer Dieng Highlands, shaped by massive anthropogenic acceleration. This study employs a geomorphological approach. Data were collected through observation, remote sensing image interpretation, literature, and documents. The data were analyzed using descriptive geomorphological analysis, supported by geographic information systems and remote sensing. There are two significant findings in this study. First, anthropogenic activities during the Anthropocene have been highly dominant, marked by extensive land use for agriculture and settlements over the past five decades. Second, the Outer Dieng Highland is a volcanic complex; however, its current geomorphological evolution is primarily driven by the acceleration of exogenic processes induced by anthropogenic activities. Erosion and mass movements occur on a large scale, increasing drainage density, particularly in older volcanic units and less-resistant materials. In sum, this study offers new insights into the impact of anthropogenic activities on the acceleration of exogenic destruction across various structures within the volcanic complex.
