Abstract

Bandung urban area is located in the intra-mountain basin which is part of upstream Citarum watersheds. The aim of the research is to analyse tectonic geomorphology of sub-watershed Ciwidey and Cisangkuy in the southern part of Bandung basin. The method use digital elevation image from DEMNAS combined with geological data. The result shows that the southern part of Bandung basin is tectonically active. This information is significant to evaluate existing spatial planning based on natural hazard point of views.

Abstract

Bekasi Regency is composed of soft soil material that has swelling potential due to its expansive properties. This study aims to identify the swelling potential of soil using clay content parameters in six undisturbed samples. The samples were tested on basic physical properties to identify soil characteristics. The results showed that the study area is composed of high-plasticity silt soils (MH) based on the USCS. The percentage of clay is 5.5% to 20.1% and the percentage of silt is 33.2% to 85.7% indicating a more dominant silt content. Clay activity ranges from 2,418 to 4,973%, indicating the presence of montmorillonitic minerals. The swelling potential shows a value from 3.5817 to 33.525% including medium to very high potential. The difference in swelling potential in the soil samples can be caused by several factors such as the percentage of clay, moisture content, and plasticity index.

Abstract

Pekalongan City is the northern coastal area of Java Island and is dominated by alluvial deposits. Pekalongan City’s rapid and fast development triggers much development to support the population’s need. Soil is vital in the construction of a building as a place for the erection of a building. This Paper aims to identify the type and soil consistency based on Cone Penetration Test (CPT) data. The data used amounted to 24 points, then identification of soil characteristics was carried out and map interpolation was carried out to determine the pattern of soil consistency distribution using Geographic Information System (GIS) software. The depth of the CPT test varies between 15.20 m - 20 m below the ground surface, where the qc value for a depth of 0 m - 20 m is 2.04 kg/cm2 to 138.68 kg/cm2. Based on soil classification by linking the conus resistance (qc) with the friction ratio (fr) shows the soil type in the study area, namely organic, clay, silt to sand with a very soft to hard soil consistency level.
