Abstract

Air source chosen because it is relatively better than the air of the river which is viewed from its quality aspect for its turbidity factor. Ground water as a source of clean water in general can be directly used for everyday life. But without realizing that ground air contains a lot of metal dissolved in air, also iron (Fe). The initial survey was conducted on February 8, 2017 at the dig wells of residents RT.08 Padang Serai Village, Bengkulu City after measuring iron (Fe) 2.28 mg / L. Coal is sedimentary rock which is chemically and physically heterogeneous and contains elements elements of carbon, hydrogen and oxygen as the main elements and sulfur and nitrogen as additional elements. Waste produced from the pecan formation process is a pecan shell so far has not been used optimally. Pecan shell weight reaches two-thirds of the weight of whole pecan seeds and one third is the core (karnel) of candlenut. This waste will be very helpful for people who use products that have selling value, namely as active charcoal products. This type of research uses a pure experimental method (True Experimental) with the design of the Post Test with control group, which is research conducted before and after. The results of the study showed that iron (Fe) content in screening using a combination of control tests was 2.28 mg / l. Results or a decrease of around 84.21%. Based on the table the average average of iron (Fe) is 0.360 mg / l. The lowest mean was 0.23 mg / l and the highest was 0.45 with a confidence level of 95% or a significance of 5%, averaging a decrease in the range of 0.2483 mg / l to 0.4717 mg / l.
