Abstract

Sand mining activities that continue to increase as a result of increasing demand for raw materials for infrastructure development have an impact on the environment. Negative impacts on the environment will occur if sand reduction can not be properly managed. One of the locations that is often used as a sand mining activity is the watershed. One of the river basin areas that contain sand mining activities is the Serayu DAS of Cilacap regency. In this research, the analysis of sand mining impact on physical quality of serayu river in Cilacap regency. Physical parameters measured were temperature, total dissolved solid (TDS) and electrical conductivity (DHL). The measurement results were conducted in 4 stations from upstream to downstream of Serayu River Cilacap Regency resulting temperature value of water between 30oC -31.5oC. The TDS value is in the range of 100 mg / L - 140 mg / L and the DHL value is in the range of 100 μS / cm - 200 μS / cm. Sand mining activities affect the rise of TDS and DHL in serayu river even though the value is still below the quality standard. Keywords: physical quality of river water, serayu river, sand mining

Abstract

Serayu River crossing several districts Wonosobo, Banjarnegara, Purbalingga, Banyumas, until empties into Cilacap. This research was conducted at Banyumas and Cilacap regency. Banyumas Regency, Kebasen consists of three stations in the sand mining area before sand mining, sand mining location, after sand mining. Cilacap regency consists of three stations Sampang, Maos and Slarang. The method used there are two that is purposive sampling method for sampling location and method of pollution index (IP) to determine water quality of Serayu River. From the calculation of IP method, the water quality of Serayu River in Banyumas Regency is obtained at station 1, 2 and 3 (0,922), (0,921) and (0,934). Meanwhile, located in Cilacap Regency, obtained at stations 1, 2 and 3 of (0.897), (0.921) and (0.891). Based on Ministry Decree No.115/2003 relationship value of IP with water quality status is still included in the IP value of 0 to 1.0 is the status of good condition quality.
