<![CDATA[Utilization of water for agricultural purposes is the highest, reaching 70% of the total utilization of water resources globally. In the Glundengan Irrigation Area, Wuluhan District, Jember Regency, with an area of 4996 ha, irrigation water is taken from the Bedadung River, and the excess water is discharged from the Glundengan Irrigation Area to the Bedadung River. This encourages research on the quality of irrigation water in these irrigation areas. This study aims to analyze the quality of irrigation water, especially the elemental content of potassium in the Glundengan irrigation channel. In the analysis of the quality of irrigation water, temporary sampling was carried out at two points, namely in the primary channel which carries water to the paddy fields and in the drainage channel which removes excess water from the irrigation area. The temperature and pH parameter analysis method used the standard SNI 6989.57:2008, while the K parameter analysis was carried out in the CDAST laboratory using the Flame Photometry-AAS method. The results of the analysis are compared with the water quality standards in Government Regulation No. 82 of 2001 (PP 82/2001): Management of Water Quality and Control of Water Pollution. The results of the analysis show that the temperature parameters in the primary and exhaust channels are 24°C respectively. The pH parameters in the primary and sewer channels were 7.5 and 7.2, respectively. The K parameters in the primary and sewer channels were 0.00593 mg/l and 0.00745 mg/l respectively, these figures were relatively small. These three parameters meet the water quality standards of Class II according to PP 82/2001.]]>
