Abstract

Serayu River Watershed is one of the watersheds in Central Java that covers several districts including Wonosobo, Banjarnegara, Purbalingga, Banyumas, and Cilacap. The condition of the Serayu River Watershed at this time has experienced damage and environmental pollution which has resulted in a decrease in the quality of Serayu River Water. Calcium is one of the minerals present in water and sediment. Calcium content is influenced by reactions involving carbon dioxide gas either due to respiration of plants or aquatic animals. The presence of domestic wastewater is an external element that can affect high calcium concentrations in waters. The purpose of this study was to determine the distribution of Calcium (Ca) in the Serayu River Watershed. Sampling was conducted in November 2023 located in the Serayu Watershed Area. Sampling was carried out at 15 points of the Serayu River Watershed. The method used is titrimetric analysis. The analysis results obtained are the highest Calcium (Ca) value found in Menyawak River at 52.40 mg/L. The calcium distribution map shows a red interpolation color. The lowest Calcium (Ca) value is found in the Kalisapi River at 19.20 mg/L. The calcium distribution map shows a yellow interpolation color.

Abstract

The Serayu River Basin (DAS) spans 180 km and traverses several districts in Central Java, including Wonosobo, Banyumas, Banjarnegara, Cilacap, and Purbalingga. Significant pollution has been observed in the Serayu River Basin, with the primary sources of pollution being agriculture, industry, and community activities. The objective of this investigation is to evaluate the Serayu River Basin's condition in relation to the STORET method and Class I, II, III, and IV water quality standards, as well as physical and chemical parameters. Ex situ analysis of water samples was implemented through purposive random sampling in the survey methodology. Class I pollution levels in the Serayu River Basin are classified as Category D, which denotes substantial pollution, according to the STORET method. Class II is classified as Category C, which denotes moderate pollution, as indicated by a STORET index value of -26. Several research locations exhibit water parameters that exceed the quality standards, including pH, DO, COD, phosphate, and ammonia. In order to preserve the purity and condition of the Serayu River Basin, it is necessary for all stakeholders, including the community, to participate. Furthermore, the management of the Serayu Watershed necessitates the implementation of control strategies or efforts. Keywords: Basin; River pollution; Serayu; STORET; Water Quality
