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.

Abstract

Industrial textile effluents containing Remazol Brilliant Blue R (RBBR) represent a significant environmental challenge due to their persistent nature and resistance to conventional biological treatment methods. This research explores the development of nitrogen-enriched carbon materials derived from palm oil empty fruit bunch (PEFB) cellulose as an effective adsorbent for RBBR elimination from contaminated water systems. The synthesized material was produced through thermal treatment at 700°C, enabling the formation of pyridinic nitrogen groups that improve surface alkalinity and create electron-rich active sites. Material characterization employed XRD, FTIR, and SEM-EDS techniques to evaluate structural and chemical properties. Laboratory-scale adsorption studies examined the influence of starting dye concentrations (100-500 mg/L) and reaction duration (10-120 minutes). Results demonstrated optimal fitting with the Freundlich isotherm model (qₘ = 434.78 mg/g) and pseudo-second-order kinetics, suggesting heterogeneous multilayer adsorption dominated by chemical bonding mechanisms. The proposed interaction mechanism involves electrostatic attraction between RBBR sulfonate functionalities and protonated pyridinic nitrogen sites under pH 6 conditions.
