PENGARUH KONSENTRASI EKOENZIM TERHADAP pH, TDS, DO DAN BOD AIR LIMBAH BUDIDAYA UDANG DI PACITAN SEBAGAI SUMBER BELAJAR BIOLOGI

One of the environmental elements that is crucial for the growth and development of living things is water. Currently, many water resources are polluted or damaged. Damage to water resources often occurs in certain areas, resulting in a decline in the quality of these waters and the surrounding resources. The purpose of this study was determine the effect of administering ecoenzymes on pH, TDS, DO and BOD of shrimp farming wastewater in Pacitan. The method of this study was experimental using a completely randomized design with treatment concentrations of 5 ml, 7 ml and 10 ml of ecoenzyme as well as a control treatment. The sample used in this study consisted of wastewater with pH, TDS, DO and BOD tests with 4 treatments and 6 repetitions. Observasional data using the One Way ANOVA test showed that there was an effect of ecoenzyme administration on pH, , DO and BOD, whereas there was no effect on TDS of ecoenzyme adminsitration in shrimp cultivation wastewater. Suggestions are given for future researchers to carry out other test measurements and with a long measurement time span.
