Batik is a widely recognized form of clothing in Indonesian society. The batik-making process uses synthetic dyes, which can pollute the environment. This study aims to modify biochar derived from sugarcane bagasse using iron (Fe) synthesis. Biochar was produced through pyrolysis, while iron was sourced from beach sand in Glagah, Yogyakarta. The research involved four stages: (1) production of biochar from sugarcane bagasse, (2) modification of biochar with iron through beach sand synthesis, (3) application of iron-modified biochar (IMB) to methylene blue (MB), and (4) analysis of biochar characteristics. The results show that iron-modified biochar (IMB) affects biochar properties. IMB falls into the micropore category with a micropore surface area of 71.1%. The optimum wavelength was 571 nm with an adsorption level of 0.155. The application of IMB to batik wastewater demonstrated that adding 6% Fe and soaking for 180 minutes achieved the highest reduction in batik wastewater at approximately 69% with an R squared value (R²) of 0.975. Degradation of batik dye with 6% Fe using the Heterogeneous Fenton method resulted in yellow color degradation of 16%, fast green 3%, methylene orange 4%, red 3%, and methylene blue 23%. These findings highlight the potential of using sugarcane bagasse as a renewable resource for producing adsorbents that contribute to effective batik wastewater treatment. [ABSTRACT FROM AUTHOR] |
