Abstract

sustainable clean water quality crisis. Clean water is difficult to obtain because river water has decreased in quantity and well water tastes salty so it cannot be consumed. This condition results in economic losses due to having to buy water as well as harming health if forced to consume well water. Water treatment by filtration using activated carbon and coconut fiber is the solution to this problem.

In the specifications, the Iodine number of activated carbon affects its adsorption ability. This study aims to see the effect of variations in the number of Iodine on activated carbon on improving the quality of water according to regulation. The method used is filtration with 3 filters containing coconut fiber 10 cm and activated carbon with different iodine numbers, which 650 mg/g, 800 mg/g and 1000 mg/g as high as 60 cm. The filter is operated for 45 minutes with sampling every 15 minutes. The parameters studied were hardness, TDS and metal levels of Lead. The data analysis method used is One Way Anova.

The results of the first water test showed that the hardness level was 890 mg/l, TDS 4460 mg/l, lead metal content was 0.0709 mg/l. the mineral content exceeds the standard. The results showed that the efficiency of hardness reached 60.78%, TDS 89.90% and Lead (Pb) 84.90% by 1000 mg/g activated carbon. The results of the regression and ANOVA showed that there was a significant effect of using variations of activated carbon Iodine at 15 minutes of operation on the decrease in water hardness, TDS and Lead metal content.
