| 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 |
