AbstractEnvironmental problems occurring in the Bandung Basin are resulted from improper management pertaining to land and spatial planning, including landuse policy and control. Arising environmental problems are covering disturbance of watershed hydrological function, surface and groundwater quality and quantity, solid waste, and air quality. Environmental studies in the Bandung Basin have been implemented by landuse change...

Hidrotermal Taran Area
AbstractTaran area is occupied predominantly by piroclastic rocks and locally intercalations of lenticular claystones and sandstones. The pyroclastic rocks are intruded by diorite, dacite and andesite, leading alteration and mineralization within the host rocks. Mineralization occurs as a vein type and is associated with a number of pervasive alteration types named respectively: quartz-illite-montmorillonite-kaolinite ± pyrite,...
Anak Krakatau Volcano
AbstractSince its appearance in 1929, Anak Krakatau Volcano has been growing fastly. The elevation of Anak Krakatau Volcano from 1930 to 2005, within 75 years, has reached 315 m high. The growth rate is approximated to be four meters per year in average. Based on calculation, the volume of the body from the sea floor since 1927 until 1981 was 2.35 km3, and then in 1983 was 2.87 km3 and then in 1990 it reached 3.25 km3. The latest...
volcanic merapi
AbstractThe Merapi Volcanic debris flow, which is familiarly known as lahar, is formed from pyroclastic deposits that is slided by high rain water. Now, the pyroclastic deposits are produced from a collapsing lava dome. The suspension flows downhill in a high speed, to produce a turbulent flow. That flow are usually developed within areas of a different morphology having high to lower slope gradient, known as a slope fold of a...
Geology of Jakarta Basin
AbstractGeologically the Batuceper and Benda Sub-Regencies belongs to the western part of the Jakarta Basin. The area is covered by coastal alluvial and delta deposits, and volcanic product. Understanding the distribution and groundwater pattern, either in the shallow part or the deep part, are of the basic thing for a geometric model and its groundwater flow in identifying the groundwater conservation.The result of the aquifer...
