Efektivitas Arang Aktif Kulit Durian (Durio zibethinus Murr.) dengan Kombinasi Media Filter dalam Penurunan Kadar Mangan pada Air Sumur

Abstract

Clean water is an essential need for sustaining life and maintaining public health. However, not all regions have access to safe water, especially areas near landfill sites. The quality of well water around landfills often deteriorates due to leachate infiltration from waste piles, which contain pollutants such as heavy metals and harmful organic compounds. One of the most commonly found heavy metals is manganese, which can pose health risks if consumed over a long period. This study aims to assess the effectiveness of durian peel activated charcoal combined with filtration media in reducing manganese levels in well water. The research used a quasi-experimental design with a pretest-posttest approach. Activated charcoal from durian peel was prepared through carbonization and activation using 0.5 M NaOH solution. The filtration media consisted of four combinations: pipe 1 (quartz sand and gravel), pipe 2 (quartz sand, durian peel activated charcoal, and gravel), pipe 3 (quartz sand, zeolite, and gravel), and pipe 4 (quartz sand, durian peel activated charcoal, zeolite, and gravel). Water samples were taken from a residential well near the landfill site in Lingkungan I, TPA Terjun, and analyzed using ICP-OES in the laboratory. The data were statistically analyzed using one-way ANOVA. The results showed that the initial manganese levels before treatment were 0.785084 mg/L. After treatment, the average manganese levels in pipe 1 was 0.761647 mg/L, pipe 2 was 0.089580 mg/L, pipe 3 was 0.191993 mg/L, and pipe 4 was 0.021699 mg/L. The results of the One Way ANOVA test showed a significant difference (p < 0.05). The combination of filtration media in pipe 4 showed the highest effectiveness with a reduction in manganese levels reaching 97.23%. It is recommended that communities begin using this simple filtration technology, and further research is needed to assess its long-term performance.
