Fisheries. Angling subject: T Technology (General) description: Water filter is a tool which commonly used to purify the stop into clean water by reducing the impurities in it. The limited availability of clean water has led many communities to use river as their main water sources. The river which frequently used for bathing, washing, and sanitation (MCK) activities is the Cisadane River in Tangerang Regency. This study aims to determine the best composition for improving water quality in terms of Total Dissolved Solids (TDS), pH, iron (Fe), and ammonia using the multi-layer water filtration. The sampling method which used in this study was simple random sampling. The research was conducted from January to March 2025. The iron concentration testing was carried out at the Health Laboratory Unit (UPT) in Serang Regency. The study consisted of three stages: designing the filter device, conducting trials, and testing water quality. The water quality parameters measured included physical (TDS) and chemical (pH, iron, and ammonia) aspects. The experimental design used was a Completely Randomized Design with two treatments (combinations) and three replications: Combination 1: 15 cm silica sand, 15 cm rubble, 15 cm activated carbon, 15 cm zeolite, and 10 cm sponge. Combination 2: 20 cm silica sand, 10 cm rubble, 20 cm activated carbon, 10 cm zeolite, and 10 cm sponge. The result showed that, the multi-layer filtration device using both filter media combinations effectively improved water quality. The best treatment was Combination 2, which reduced TDS by 73%, ammonia by 100%, and iron by 98%, while also increasing the water’s pH toward a more neutral level. Although there was no statistically significant difference between the two filter compositions (p > 0.5). date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/50506/1/Lidya%20Sephiana_4443210083_Fulltext.pdf format: text language: en identifier: https://eprints.untirta.ac.id/50506/2/Lidya%20Sephiana_4443210083_01.pdf format: text language: en identifier: https://eprints.untirta.ac.id/50506/3/Lidya%20Sephiana_4443210083_02.pdf format: text language: en identifier: https://eprints.untirta.ac.id/50506/4/Lidya%20Sephiana_4443210083_03.pdf format: text language: en identifier: https://eprints.untirta.ac.id/50506/5/Lidya%20Sephiana_4443210083_04.pdf format: text language: en identifier: https://eprints.untirta.ac.id/50506/6/Lidya%20Sephiana_4443210083_05.pdf format: text language: en identifier: https://eprints.untirta.ac.id/50506/7/Lidya%20Sephiana_4443210083_Ref.pdf format: text language: en identifier: https://eprints.untirta.ac.id/50506/8/Lidya%20Sephiana_4443210083_Lamp.pdf identifier: SEPHIANA, LIDYA (2025) EFEKTIVITAS PENGGUNAAN KOMBINASI MEDIA FILTER PENGOLAHAN AIR DENGAN METODE FILTRASI BERTINGKAT.
