P POTENTIAL OF PINEAPPLE (Ananas comosus) FILTRATES IN REDUCING THE HEAVY METAL LEAD (PB) IN TOMAN FISH (Channa micropeltes)

Abstract

The waters of the B River have lead levels which can have a negative impact on health. One type of fish that is often found in the B River is toman fish, where this condition can have a negative impact on the life of fish in the river. To reduce lead levels in toman fish can be done in various ways, one of which is using natural ingredients, including pineapple which contains many acidic compounds, one of which is citric acid. dentifying and analyzing differences in the effect of pineapple filtrate on reducing Pb levels in toman fish (Channa micropeltes) using atomic absorption spectrophotometry.The research method used to identify and the method used was experimental with the research design carried out namely experimental design. The sampling technique was purposive sampling, which was then carried out with a research design in the form of post test only and group design. Data analysis using One Way Anova. The treatment used in this research used pineapple filtrate concentrations of 50%, 75% and 100%. In this study, results were obtained where a concentration of 50% experienced a more significant decrease compared to filtrate concentrations of 75% and 100%. The data results show that pineapple filtrate has a significant effect on reducing lead levels in toman fish (p<0.05). From the three filtrate concentrations in this study, the results obtained were that at the 50% concentration there was a more significant reduction in lead levels compared to the other filtrate concentrations.
