Abstract

ABSTRACT Groundwater often contains iron (Fe). The availability of iron (Fe) in water causes some health problems, bad smell and yellow color on the tub wall. Meanwhile, corn cobs contain compounds of carbon, namely cellulose (41%) and hemicellulose (36%) which have potentials as the raw materials in charcoal making. The purpose of this research was to analyze the differences of the iron (Fe) level in the dug well water which was not given corncob charcoal and the dug well water that was given corncob charcoal. This research was in a form of experimental research. In this research, samples were divided into four groups; that is, one control group (K) and three treatment groups (X1, X2, and X3). Data were analyzed using one way anova test with α = 0.05. The research results showed that the highest ability to reduce the iron (Fe) level occurred in the X3 treatment group or experimental group of dug well water that was given corncob charcoal with concentrations of 200 gr/l for 6 hours by 84.3%. Meanwhile, the lowest ability to reduce the iron (Fe level) occurred in the X2 experimental group or dug well water that was given corncob charcoal with a concentration of 150 gr/l for 6 hours by 30.6%. It can be concluded that the most effective ability of the X3 treatment group in reducing the iron (Fe) level was on the dug well water which is given corncob charcoal by concentration of 200 gr/l for 6 hours which can decrease the iron (Fe) level on the dug well water by 84.3%. The more addition of corncob charcoal concentration in dug water well, the better its ability to decrease the iron (Fe) level in the dug well water
