Abstract

Air as one of the components that support the life of all living things on this earth, of course has a very important role. Good or bad air quality around, can be seen from the high content of carbon monoxide (CO) and particulates matter (PM2.5) in the ai. Based on data obtained from World Air Quality Report in 2021, Indonesia is a country with the 17th highest average PM2.5 concentration in the world, with a figure of 34.3 g/m³. The research method used is descriptive analysis with an empirical research approach, both digitally, virtual, and field surveys. Assisted by remote sensing technology and geographic information systems. Based on the analyzed data, trends showing West Java Province with high level of AOD, dominated by regions urban or area with density high population as well as sector quite industry growing. Meanwhile, for areas with low level of AOD, dominated by rural areas with density more population low as well as development industry that has not so growing. [ABSTRACT FROM AUTHOR]

Abstract

The Northern Bandung area covers two landforms, namely volcano and structural landforms. Unconfined groundwater has become the water source for local people's daily needs in both landforms. It is necessary to map the potential unconfined groundwater for both volcano and structural landforms due to the significant role of springs for the local people living in those areas. This research aims to map the unconfined groundwater on the volcano and structural landforms. This study employed the approaches of Analytical Hierarchy Process (AHP), Geographic Information System (GIS), and Remote Sensing (RS) using the variables of lineament density, rainfall, slope, and Topographic Wetness Index (TWI), hydrogeology, drainage density, and land use. The result shows that each variable has the Consistency Ratio (CR) below 0,1, resulting in consistent research variables and appropriate for discussion. The classification of the potential groundwater is divided into three categories: low, medium, and high. The survey validation finds that 147 springs spread at 86 high lands, 55 medium lands, and six lowlands. This model can be an alternative to map the potential unconfined groundwater in both volcano and structural areas. [ABSTRACT FROM AUTHOR]
