Abstract

The management of hazardous and toxic waste (B3 waste) is crucial in industrial sectors to prevent environmental damage and ensure the safety of humans and other living beings. This research focuses on the design and recommendation of a Temporary Storage Facility (TPS) for B3 waste at PT X, which operates in the transportation industry. The types of B3 waste identified include used oil, used rags, brake fluid, grease, and radiator water. Using a multi-method approach, the study used interviews, observations, and logbook analysis to determine the characteristics, quantities, and storage requirements of the waste. The research also adhered to Indonesian regulations to ensure compliance in waste management and storage. The recommended TPS design includes features such as proper ventilation, fire extinguishers, first aid kits, and labeling based on waste characteristics. Storage capacity calculations and layout have been optimized to match existing site conditions and ensure operational efficiency. The proposed TPS layout is expected to enhance workplace safety, minimize environmental contamination risks, and improve overall waste management practices at PT X.

Abstract

The batik industry is one of Indonesia’s rapidly growing cultural and economic sectors. However, its production process generates wastewater containing high levels of synthetic dyes, total suspended solids (TSS), and chemical oxygen demand (COD), which can deteriorate water quality. This study aims to evaluate the effectiveness of the combined electrocoagulation–adsorption process in reducing dye, TSS, and COD concentrations in batik wastewater. The electrocoagulation process used aluminum electrodes with current variations of 1–5 A and contact times of 30–150 minutes, followed by adsorption using activated carbon as the adsorbent. The results showed that the combined process achieved excellent pollutant removal efficiency. Dye concentration decreased from 6742 Pt-Co to 93 Pt-Co, TSS from 5100 mg/L to 80 mg/L, and COD from 2432 mg/L to 39 mg/L, with overall removal efficiencies of 98–99%. The optimal condition was obtained at 5A and 150 minutes of reaction time. In conclusion, the electrocoagulation–adsorption combination is proven to be effective and environmentally friendly for reducing pollutant loads in batik wastewater.
