Effectiveness of Coconut Charcoal Shell Activated Carbon Filtration to Lower Fe in Cisterns Water: A Case Study in Arsopura, Keerom Regency, Papua

Abstract

Clean water consumed daily should not contain excessive Fe (iron) because it can cause health problems. The Fe can be reduced by filtering using activated carbon such as those found in coconut shells. For this reason, this study will analyze the effectiveness of iron filtration in excavated well water in Arso Pura, Keerom Regency, Papua Indonesia. The method used is an experiment with Randomized Complete Block Design (RCBD). Purposive sampling was carried out on community dug well water in Arso Pura, Keerom Regency, Papua by measuring Fe levels before and after using coconut shell activated carbon and the use of miner areas of 2 Inches, 3 Inches and 4 Inches. The results of the Anova test, namely a p-value of 0.00<0.05, indicate that filtration with coconut shell charcoal and the addition of a cross-sectional area of the cross-sectional area have a significant effect or significantly different treatment on Fe (Mg / l). The result was with a cross-sectional area of 2 inches H with a decrease of 47.62%; 3 Inch to 59.05%, and 4 Inch to 63.81%. The results of the screening have not been able to meet the requirements for Fe levels in potable water. For this reason, a larger miner expansion mechanism and/or a different filtration approach is needed that must be carried out on the dug well water in Arsopuro to make it drinkable.
