![]() ![]() ![]() The influence of sampling locations was not significance. The concentrations of pesticide and elements of the water samples in wet season were less than that of dry season, and reverse with that of sediment samples. DDT compound has not been detected in sediment as well as water samples. In sediment sample have been detected heavy metals of Ca, Mg, Mn, Fe, Hg, Cd, Cr, Co and corbophuran compound. Analysis result showed that 5 heavy metals i.e.: Ca, Mg, Mn, Fe and Hg, and also carbophuran have been detected in water sample. ![]() Determination of heavy metal used Neutron Activation Analysis method (NAA), determination of DDT compound used gas chromatography (GC) method and of carbophuran compound used high performance liquid chromatography (HPLC). Sampling has been done in March and September 2004 as grab sample. International Nuclear Information System (INIS)ĭetermination of Ca, Mg, Mn, Fe, Hg, Cd, Co elements, compound of Carbophuran and DDT content in sediment and water of Bribin Underground River at Gunung Kidul has been carried out. Water resources management is related to existence of karst component (eksokarst, include management of springsĮvaluation of Metal Elements and Pesticide Content of Water and Sediment Samples of Bribin Underground River at Gunung Kidul (Part I) Karst management policy strategies based on regional are management karst area plan overall. Karst management policy strategies based on characteristic karst was pressed in surface appearace(eksokarst. Efforts conservation and management strategies commits based on characteristic karst and regional. The high levels of extent of damage karst among others, existance of great mining, springs, and building over the karst surface. The high levels of extent of damage karst is Ponjong, Sawahan, Sumbergiri Village, area of 9424.24 hectares. Administratively, extent of damage karst is very high located in Kenteng, Karangasem, and Bedoyo Village, area of 922.27 hectares. Considered of karst damage parameters, includes morphology change caused by mining, existance outlet basin, land cover, condition of springs, caves, and existance of building over the karst surface must be conducted assessment in extent of damage. This research was conducted using field observations and literature studies related to condition os study area. Extent damage of karst is assessed based on morphology of karst basin. Identification extent of damage in Bribin Watershed into one of urgency things because the area as underground supplier into reservoir river of Bribin, Baron, and Seropan was utilized for the needs of population. Environmental management in order to achieve sustainability of water resources was emphasized on water recharge, namely Bribin Watershed of upstream section. Existance of Bribin Watershed is very important for continuance and welfare of population which must be managed sustainability. Reservoir Bribin 1, Bribin 2, and Seropan located in the Dadapayu village Semanu Sub-District utilize to comply needs of population in Gunung Kidul Regency. Kajian Kerusakan Lingkungan Karst sebagai Dasar Pelestarian Sumberdaya Air (Kasus di DAS Bribin Hulu Kabupaten Gunung Kidul Daerah Istimewa Yogyakartaĭirectory of Open Access Journals (Sweden)ĪBSTRACT Groundwater resources in Gunung Kidul Regency synonymous with underground system Bribin ( Bribin watershed. ![]()
