Abstract

In Kemlagi District, Mojokerto Regency, a small and medium-sized batik enterprise, CV Ulur Wiji Muda Berdaya, has gained popularity among millennials due to its use of natural dyes that are environmentally friendly. The products have not only attracted domestic consumers but have also reached international markets. Despite this achievement, the enterprise continues to face a major challenge in managing batik dye wastewater, which has not received optimal treatment. To solve this issue, a community service program was implemented to provide technical assistance in wastewater treatment through training on filtration adsorption methods for the employees of CV Ulur Wiji. The filtration unit employed adsorption media consisting of foam filters, zeolite, activated carbon, coral stone, and Malang sand. The questionnaire results confirm that the partner has improved the application of wastewater treatment technology as a result of the program. The results of batik waste processing indicated an improvement in the waste quality, changing from a turbid color to a clearer appearance, with an initial pH of 6.3; after undergoing filtration-adsorption, the pH shifted to near neutral at 6.9. Furthermore, an additional outcome of this program is the successful development of an appropriate technology system for treating wastewater from batik dye using filtration–adsorption techniques.

Abstract

Batik wastewater generated by micro-scale industries typically contains high organic loads, intense coloration, and fluctuating pH, exceeding national discharge limits. This study aims to design, install, and evaluate a simple pilot-scale wastewater treatment plant (WWTP) using a coagulation–filtration–adsorption process for UMKM Batik Ulur Wiji in Indonesia. Wastewater quality was analyzed before and after treatment for pH, BOD, COD, TSS, TDS, turbidity, and color referring to Indonesian Ministry of Environment Regulation No. 5/2014. The results show a substantial improvement in water quality, with COD reduced from 857 to 112 mg/L and BOD from 358 to 68 mg/L. Turbidity decreased from 218 to 14 NTU, and color removal was visually significant. The treated effluent met key parameters for non-potable reuse. A partner satisfaction survey revealed increased environmental awareness, full operational understanding of WWTP, and long-term commitment to system use. This study demonstrates that simple low-cost treatment units are effective for batik wastewater management in micro-industries and provide a replicable model for community-based environmental interventions.
