Management of Textile Industry Wastewater in the Cikijing River for Paddy Field Irrigation in Jelegong Village, Rancaekek Sub-district, Bandung Regency

Abstract

The Cikijing River in Rancaekek, Bandung, is severely polluted by the discharge of untreated textile industry wastewater, characterized by high concentrations of pollutants such as dyes, chemicals, and heavy metals. Critically, this contaminated river water is used directly by the community in Jelegong Village for paddy field irrigation. This research aims to (1) analyze the water quality of the Cikijing River and its impact on the paddy field soil, and (2) formulate an effective wastewater management model to ensure the water is safe for irrigation purposes. The research methodology involved water sampling from multiple points along the Cikijing River and soil sampling from the paddy fields in Jelegong Village. These samples were analyzed in a laboratory to measure key parameters including BOD, COD, TSS, pH, and heavy metal concentrations (e.g., Pb, Cr, Cu). The results indicate that the water quality of the Cikijing River consistently fails to meet the established standards for irrigation water, and an accumulation of heavy metals was detected in the paddy soil. As a solution, this study recommends an integrated management scheme involving the enforcement of industrial wastewater pre-treatment, the implementation of communal Wastewater Treatment Plants (WWTPs), and periodic monitoring to ensure agricultural sustainability in Jelegong Village.
