Pengaruh Penggunaan Hidrogen Peroksida (H2O2) Terhadap Kepadatan Mikroalga

---

Uncontrolled growth of microalgae can cause algae blooms in waters, which have a negative impact on aquatic ecosystems. Blooming algae can reduce water quality, reduce dissolved oxygen, and release toxins that are harmful to other aquatic organisms. Based on research, hydrogen peroxide has been proven to be effective in reducing the density of microalgae at certain concentrations. However, in aquatic resource management, the use of hydrogen peroxide for microalgae control must be optimized so that it is effective and does not harm non-target organisms or the aquatic environment. Therefore, research was carried out regarding the effect of using Hydrogen Peroxide (H2O2) on the density of microalgae (Chlorella sp.). This research was conducted in January-February 2024. In this research, preliminary tests were carried out with concentrations of 17.5%, 25% and 37.5% without repetition. Preliminary tests were carried out to find the right concentration to achieve reduced microalgae density. Because no significantly different results were found, it was continued to the main study with concentrations of 37.5%, 42%, and 48% by randomizing all of the replications. The results of the research at 3 hours were 652 x 104 Chlorella cells/ml, 42% found 629 x 104 cells/ml, and at a concentration of 48% 491 x 104 cells/ml. at 6 hours the result was 566x104 in 37.5%, in 42% the result was 452 x 104 cells/ml, in 48% it was 302 x 104 cells/ml. Meanwhile, for 9 hours at a concentration of 37.5% it was 246 x 104 cells/ml, at a concentration of 42% it was 185 x 104 cells/ml, and at 48% it was 128 x 104 cells/ml.
