Abstract

Preliminary test results in the Carton Box Company with BOD parameters of 312.74 mg / l and COD 639.25 mg / l did not meet the requirements according to East Java Governor Regulation Number 72 of 2013. The high parameters are due to improper waste management to reduce BOD and COD. The purpose of this study was to examine the ability of water jasmine plants (Echinodorus palaefolius) to reduce BOD and COD levels in wastewater in the Carton Box Company.

This research is a pure experimental study using a Pretest-Posttest Control Group Design research design. This study uses a variation of water weight of jasmine plants as much as 400 gr, 500 gr and 600 gr with a treatment period of 7 days. Data collection techniques were obtained from laboratory test results. The data obtained were statistically tested using the One Way Anova test.

The results of the average examination after treatment of BOD levels with the treatment of 400 gr, 500 gr and 600 gr plants respectively were 168.95 mg / l, 129.41 mg / l, and 65.29 mg / l, the COD levels were respectively 431.62 mg / l, 273.33 mg / l, and 95.98 mg / l. The biggest decrease occurred in the variation of plant weight of 600 gr each per 5 liters of wastewater, namely BOD by 86%, COD by 91%. One Way Anova test showed a result of p < 0.05 so that there were significant differences.

This research shows that phytoremediation using water jasmine plants can reduce BOD and COD levels in wastewater. For the company, it is necessary to carry out further processing with phytoremediation techniques for liquid waste before being discharged into water bodies so that it can meet the quality standards of the East Java Governor Regulation Number 72 of 2013.
