- Abstract
Corn cobs and bagasse are materials used for making activated carbon that are easy to find. Additionally, they are agricultural waste that cannot be consumed. This study aims to analyze the potential of activated carbon from agricultural waste, namely corn cobs and bagasse, in reducing the levels of chromium heavy metal, and to analyze the dose of activated carbon from agricultural waste which is effective in reducing the chromium levels in the batik waste. The method used was experimental with a completely randomized factorial design. The doses of activated carbon used were 0.5, 1.5, and 2.5 g. Meanwhile, the contact times used were 30, 60, 90, 120, and 150 minutes. The results showed that the initial chromium content was 0.144 mg·L-1, and after given treatment it decreased to below 0.024 mg·L-1. The activated carbon from corn cobs and bagasse was able to reduce the chromium levels with the most effective dose of 2.5 g·L-1 and a contact time of 120 minutes. Meanwhile, the water quality parameters showed temperature stability (23–25 °C) during the experimental period, while the pH increased to 9–11.
