Abstract

Liquid coffee waste has the main component in the form of organic matter which is very resistant to increasing pollutant loads. Preliminary research results show that the level of pollution exceeds the quality standard with the test results of 23 ppm BOD and 72 ppm COD, so we need a way to prevent pollution. One way that can be used is the phytoremediation method by utilizing plants as pollutant degrading agents. The purpose of this research was to determine the effectiveness of lotus in degradation of BOD and COD of liquid coffee waste. The research method used an experimental method with a Completely Randomized Design consisting of four variations of lotus biomass 0 g, 25 g, 50 g, and 75 g with three replications within 6 days. The results showed a degradation of BOD and COD levels varied. The most effective treatment for lotus phytoremediation on day 3 was P3 with a biomass of 75 g resulting in a degradation of BOD and COD reaching 72% and 71% which met the PP RI No. 82/2001 with a maximum limit of 3 ppm BOD and 25 ppm COD. The results of the homogeneity of variance test showed that the four treatments had homogeneous variance and analysis of variance showed that F count > F table 5% (4.07) and > F table 1% (7.59). These results indicate that lotus is effectively used as phytoremediation of liquid coffee waste. The conclusion of this research is that lotus is effective in BOD and COD degradation of liquid coffee waste.

Abstract

Coffee liquid waste contains organic matter which can be at risk of increasing water pollution levels. The results of the preliminary research carried out showed that the level of pollution due to coffee liquid waste exceeded the quality standard, with the results of the BOD test results being 23 ppm and COD 72 ppm, so we need a way to reduce pollution. Phytoremediation is a method of natural waste handling using certain plants in collaboration with microorganisms in the media (soil, coral, water) so that it can change contaminants to be reduced or harmless. This study aims to determine the effectiveness of Salvinia molesta phytoremediation in reducing BOD and COD levels. The research design used a completely randomized design (CRD) with four treatments with three replications. The research data were tested using the Analysis of Variety Prints and the Duncan's Multiple Distance Test continued test. The results showed that the effectiveness of Salvinia molesta in reducing BOD levels was found in P3 obtained by an average of 8.37 ppm (73% decrease) and reducing COD levels by an average of 25.37 ppm (73%). Based on these results, it can be concluded that P3 is effective in reducing BOD and COD levels of coffee liquid waste.
