abstract: Cyanide waste can decompose naturally through oxygen in the air, but this natural decomposition process certainly has a negative impact on the environment so that cyanide waste is destroyed or processed as a form of responsibility for cyanide use activities so as not to pollute the environment. . Optimizing the reduction of cyanide levels using simulation of waste samples originating from sodium cyanide (NaCN) with NaOH as a conditioning agent. Cyanide simulation waste is an alternative that can be used to determine the optimum concentration for the addition of sodium metabisulfite, hydrogen peroxide and reaction time. This is because the simulated waste does not contain impurities or other substances, so it can be ensured that the reduction results are pure from the cyanide reaction with sodium metabisulfite and hydrogen peroxide. Destruction Simulation of cyanide waste was carried out by adding variations of sodium metabisulfite, hydrogen peroxide, and reaction time to a volume of 500 ml of simulated waste sample. The analytical method used in this research is an argentometry titration using indicators 5-(4-Dimethylaminobenzylidene)-rhodanine. To reach the optimal point, researchers use analysis Response Surface Methodology Central Composite Design. From the results of the experiments that have been carried out, addition of hydrogen peroxide and the reaction time is more effective reduced cyanide levels in simulated waste samples, compared to sodium metabisulfite even in the absence of a catalyst and oxygen in the air. The optimal point in reducing cyanide levels is achieved by reduction percentage of 68.42% with the addition of 2,5 ml hydrogen peroxide, 0,5 grams of sodium metabisulfite, and treatment time 180 minutes. The recommended model form RSM CCD method is Quadratic with an error percentage of 3.79%.
