| dc.description.abstract | Batik industrial waste treatment is carried out using the coagulation method with Chemical Oxygen Demand (COD) analysis parameters. This analysis aims to determine the optimal ability of coagulants to decrease COD levels. Analysis of COD levels was carried out using closed reflux with a calibration curve method using a UV-Visivle spectrophotometric instrument. The natural coagulant used was rambutan seed (Nephelium lappaceum L.) which was characterized by FTIR and SEM-EDX. COD reduction efficiency is done by looking at the effect of pH, coagulant time and coagulant dose. The results showed that the optimum pH of rambutan seed coagulant was at acidic pH with a COD reduction performance of 45.03%, the coagulation stirring time showed optimum results for 35 minutes and the flocculation process was 15 minutes with a decrease in COD of 70.16% and the dose of coagulant was found to give good results. optimum at 1 g with a decrease of 75.64%. Based on this, it is concluded that rambutan seeds (Nephelium lappaceum L.) have the potential to be used as a natural coagulant to reduce the use of chemical coagulants in the wastewater treatment of the batik industry. | en_US |
