Efektivitas Penyisihan Kadar BOD Limbah Cair Pengolahan Ikan Menggunakan Tanaman Melati Air (Echinodorus Palaefolius) Dengan Sistem SSFCWS

Abstract

Fish processing liquid waste is waste that contains organic material from fish processing activities that have the potential to pollute the environment if the resulting waste is not treated properly and correctly. This research was conducted to determine the efficiency of removal of BOD levels by Phytotreatment using water jasmine (Echinodorus palaefolius), and the effect of the number of plants on BOD levels of fish processing wastewater. Sampling was carried out in the fish processing industry in Pasuruan, East Java. The research stages started from preliminary research, the phyto-treatment process, and data analysis using Two-Way ANOVA. Plant acclimatization with concentrations of 0%, 25%, 50%, 75%, and 100% fish processing wastewater with water jasmine (Echinodorus palaefolius) gradually for 18 days. Phytotreatment was carried out using a waste concentration of 75% for 20 days to determine the decrease in BOD levels. Based on the results of the analysis, it can be concluded that water jasmine (Echinodorus palaefolius) can absorb organic matter in wastewater treatment with BOD removal efficiency of 77% respectively. The results of statistical tests carried out showed that the weight of water jasmine (Echinodorus palaefolius) had a significant effect on BOD levels.
