Abstract

Rumpin sub-district is an area in the northwest part of the capital city of Jakarta which is included in the division of West Bogor Regency. The potential and resources possessed are the main reasons for the new city development plan to be carried out in the region. This study aims to provide information related to regional development planning based on environmental geology. The research method is taking geological, hydrological, disaster and current land use data as well as collecting secondary data obtained from data guardians or related agencies to support the data with the final result in the form of recommendation maps and evaluation of land use in the research area carried out by scoring. quantitatively and assessment of overlapping (overlay) SKL maps using mapping software. The results showed that the study area had a moderate-good soil bearing capacity, a poor grade of sandy soil, three classes of slopes, namely flat-sloping (0-15%), moderately steep (15-25%) and steep-very steep (> 25%). Based on the availability and productivity of aquifers, they are divided into two units, namely local, medium-production aquifers and areas of scarce groundwater. The disaster factor is soil movement from the Land Movement Vulnerability Zone Map showing that the Rumpin area is included in the Low to Medium Ground Movement. The results of the weighting of the research area are divided into three regional recommendations, namely good, medium and bad, and an evaluation of land use is carried out with the current land use map region.

Abstract

Rumpin is an area close to the capital city and is an area that is developing geology. Rumpin area is mostly formed by Quaternary surface deposits (Alluvium, Pematang Pantai, Fan Alluvium and Tufa Banten) and a small part (southern) is Tertiary sedimentary rock (Genteng Formation and Serpong Formation). The Rumpin area does not yet have a land use, the regional potential and the potential for disasters in the area are very large, especially flood disasters because the area is crossed by the Cisadane river. Flood is a disaster that often occurs and can cause huge losses from various parties. Therefore, a study is needed to classify flood-prone areas as an effort to mitigate flooding. The Cisadane watershed area is an area that will be studied using a Geographic Information System (GIS). GIS can be used to classify sub-watersheds that are considered flood-prone areas. The data used is the Topographic Map 1: 100,000 from the SRTM data. The method used is the scoring method, namely morphometric, geomorphological and land use planning parameters, which are then weighted and scored according to their flood vulnerability by utilizing a geographic information system (GIS) so that they can classify flood-prone area objects in digital form in the area.

Abstract

Disasters are events that can endanger life and disrupt people's lives. It can be caused by natural and non-natural factors, as well as those caused intentionally by humans, resulting in fatalities, property losses, natural and environmental damage, and psychological effects on disaster victims. Natural disasters themselves are a threat to the community and the Regent. The Rumpin District, Bogor Regency, as the capital of the candidate for the newly autonomous region of West Bogor Regency, has triggered population growth and the development of the area has become very fast. Deliberation of the potential and resources owned and assessed to be a strategic area because it borders the City of South Tangerang, Banten. Therefore, the activities of managing natural resources and the environment as well as regional development must pay attention to the preservation of their functions and capabilities so that development activities do not become a trigger for disasters, and the location of the development must be in an area that is safe from disasters. This study was conducted to find out how the geological conditions are related and the factors that affect the potential for landslides, and to make a map of the land movement susceptibility zone in the research area. This research uses Geographic Information System (GIS) and the parameter assessment method, where the parameters needed are geological parameters, soil type, rainfall, land use, and slope. The disaster risk zoning is expected to be a source of knowledge for the community and the city government of Bogor for disaster mitigation and increase awareness related to land movement vulnerability zones.
