Abstract

Rock is a solid substance that contains minerals and is formed naturally. Joint is a fractured plane without a shift in the rock body and can be present systematically formed by tectonic forces and can be analyzed as an interpretation of its forming tectonic forces from systematic data. This research was conducted in Sugai Cibogo, Padalarang, West Bandung Regency, with coordinates 06049'29.07 " S and 107026'17,69 "S. This type of research used in research is a quantitative descriptive study by telling the conditions of the field conditions as is. The purpose of this study was to determine the direction of rock fractures in the Cibogo Padalarang river and how to take samples in the Cibogo Padalang river. The results of this study found that the fracture that occurred was a normal fault because sigma 1 was bigger than the other sigma and the sample was taken using a geoglogic hammer, compass, meter by determining the age of rocks and others.

This study aims to analyze changes in coastline, land cover and sedimentation in the cathment are Limau. The methods used in analyzing the data are digitizing satellite images, interpreting satellite images, and Total Suspended Solid in the cathment area Limau. The results show that the largest land use changes occurred in the middle and downstream cathment area Limau, the land changes that occurred were residential land which changed by 29 ha, fields 11 ha, open land 12 ha, rice fields 3 ha, and plantations decreased by 52 ha in 1998 Until 2018, changes in cover affected shoreline conditions in the form of accretion and coastal abrasion which were influenced by sedimentation in the cathment area Limau which changed. Abrasion of 1.59 ha and accretion of 4.8 ha in 1998-2003 and accretion of 20.37 ha in 2003- 2018. The greatest sedimentation occurred around the mouth of the Das Limau river, the largest sedimentation occurred in 2018 while for the previous year the sedimentation rate was not too large.
