“…The geomorphology of the study area consists of Alluvial Plains, Almost Plains and Isolated Hills. The naming of the geomorphological units in the study area refers to van Zuidam's classification [11] which divides unit characteristics based on the general relief and slope as well as the genetic description of the morphology formed from endogenous and exogenous processes. The unit is characterized by a relatively loose contour pattern.…”

The research aims to assess the geothermal potential and provide a better understanding of the geology and geophysics of the area. The study utilizes various methods, including geological mapping, geochemical analysis, and magnetic and electromagnetic data analysis, to gain insights into the subsurface structures and characteristics of the geothermal system. The study area can be divided into three geomorphological units: Alluvial Plain Unit, Near Plains Unit, and Isolated Hill Unit. The study area exhibits a stratigraphy consisting of three primary units: Talumopatu granite units, Talumopatu sandstone units, and alluvial deposit units. The subsurface lithologies of the Talumopatu manifestation area were analyzed using the Wenner – Alpha configuration ERT method, revealing two distinct lithologies. The first lithology consists of sandstones with a resistivity value ranging from 4.2 to 39.0 Ωm and a thickness of 1.25 to 12.4 m, which act as a permeable layer capable of transmitting water. The second lithology is granite with a resistivity value ranging from 118 to 360 Ωm and a thickness of 3.75 to 15.9 m. This information provides valuable insights into the subsurface characteristics of the area, including the presence of permeable layers and the geological composition of the lithologies

“…The geomorphological map of the area was obtained following the morphogenetic criteria of Van Zuidam and Van Zuidam Cancelado (1986), which used satellite image interpretation (Landsat 7 ETM: 01/15/2001) and the GIS software ILWIS (Integrated Land and Water Information System), developed by the International Institute for Geoinformation and Earth Observation (ITC) in The Netherlands. The best satellite view was the 741 band in the RGB channels to generate the thematic maps because this combination clearly identifies the difference between vegetation, ice cover, lithologies with different reflections, and, therefore, delineates the landform boundaries.…”

“…Slopes (0-2%) occupy most of the area (8054.84 ha). Areas with a slope (0-2%) are flat or almost flat morphology, no denudation, no difficulty in processing [27]. Rainfall in the Semarang Coastal Area is 2500-3000 mm/year, evenly distributed in all areas.…”

Population growth has an impact on increasing the need for land use. The availability of land for settlement development in urban areas is very limited, so that there are people who occupy land that is unsuitable. The coastal area of Semarang City is located on the northern outskirts of the city, indicating an increase in settlement areas. The characteristics of coastal areas that have flat morphology and border the sea are flood-prone areas. This study aims to analyze land suitability for settlement development in the coastal area of Semarang. Suitability based on land capability, and completeness of settlement facilities. To provide information about settlement development locations that are safe and have complete facilities. Settlement development locations in accordance with spatial planning documents and land availability. Using quantitative descriptive methods and spatial analysis with geographic information systems and remote sensing imagery as spatial data. The stages of analysis include analysis of physical aspects, analysis of land capability, analysis of settlement service levels and analysis of land suitability for settlement development. The results showed that currently there are 1696.80 ha of suitable land for the development of settlements in the Semarang Coastal area. Most of them are in Genuk District (60.88%) and Tugu District (26.89%). The research findings can be used as government considerations in compiling spatial policy recommendations related to Sustainable Settlement Development in the Coastal Areas of the Semarang City.
