Abstract

Abstract Leachate from landfills, if left untreated, can lead to environmental pollution, especially if the leachate is discharged directly into the river. One way to reduce the environmental impact of seepage water is to treat the seepage water with a biofilter. The purpose of this study is to clarify the effect of leachate treatment with the use of biofilters. The method used in this study was to use laboratory-scale experimental methods. The biofilter used in this study was a combination of palm oil, sand, coconut shell charcoal, coconut fiber, gravel, and stone. The parameters measured in this study include pH, BOD, and COD. Based on the results of the studies conducted, biofilters have a significant impact on reducing the chemical content in the leachate. Biofilters have been shown to reduce the content of chemicals in osmotic water, so they do not pollute the environment, especially when it is discharged into rivers. The results showed that the COD and BOD values of the exudate were significantly reduced 6 weeks after treatment with the biofilter. The effectiveness of biofilms in reducing the chemical content in the leachate due to the presence of microorganisms growing in the biofilter layer is also based on the presence of biofilms formed by contact between the leachate and the biofilter.

Abstract

People's need for vegetables is increasing day by day. One type of vegetable that is in great demand by the public is chickpeas. The productivity of chickpeas in 2014 decreased, the decline was caused by various things, one of which was the decline in soil quality due to excessive use of inorganic fertilizers. One way to increase the productivity of chickpeas is to replace inorganic fertilizers with organic fertilizers. The purpose of this study was to determine the effect of chicken manure and rice husk charcoal as a planting medium on the growth and yield of chickpeas. Based on the results of research and data analysis, it was found that the combination of treatment of chicken manure (P2), combination of soil + chicken manure (P4), soil + husk charcoal + chicken manure (P6) and soil + husk charcoal (P5) had a significant effect. significant effect on the growth of bean plants. The use of chicken manure and rice husk charcoal has also been shown to be able to increase the production of chickpeas by 200-500 %.
