Due to the limited availability of clean water, many communities rely on river water. One such river frequently used by local residents for bathing, washing, and sanitation is the Cisadane River. This study aimed to determine the most effective filter composition for improving water quality parameters, including Total Dissolved Solids (TDS), pH, iron (Fe), and ammonia (NH₃). The research was conducted from January to March 2025 at the Aquaculture Laboratory, Faculty of Agriculture, Sultan Ageng Tirtayasa University, and the Health Laboratory Technical Implementation Unit of Serang Regency. The experimental method used was a Completely Randomized Design (CRD) consisting of two treatments (filter compositions) with three replications: composition 1 (15 cm silica sand, 15 cm rubble, 15 cm activated carbon, 15 cm zeolite, and 10 cm sponge) and composition 2 (20 cm silica sand, 15 cm rubble, 15 cm activated carbon, 10 cm zeolite, and 10 cm sponge). The results showed that both compositions improved water quality in terms of TDS, pH, Fe, and ammonia levels. The best performance was observed in composition 2, which produced the highest average pH (7,79 ± 0,11), and reduced TDS by 64% (100,33 ± 1,53 mg/L), Fe by 97% (0,013 ± 0,02 mg/L), and ammonia by 90% (0,05 ± 0,09 mg/L). The highest water discharge rate was found in composition 1, with an average flow rate of 0,029 L/s. Analysis of variance indicated that the filter composition had a significant effect (p < 0,05) on the TDS, pH, Fe, and ammonia levels of Cisadane River water. date: 2025 type: Thesis type: NonPeerReviewed format: text language: id identifier: https://eprints.untirta.ac.id/50585/17/Lusi%20Oktaviani_4443210043_Fulltext.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50585/18/Lusi%20Oktaviani_4443210043_01.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50585/3/Lusi%20Oktaviani_4443210043_02.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50585/4/Lusi%20Oktaviani_4443210043_03.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50585/5/Lusi%20Oktaviani_4443210043_04.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50585/6/Lusi%20Oktaviani_4443210043_05.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50585/7/Lusi%20Oktaviani_4443210043_Ref.pdf format: text language: id identifier: https://eprints.untirta.ac.id/50585/19/Lusi%20Oktaviani_4443210043_Lamp.pdf identifier: OKTAVIANI, LUSI (2025) EFEKTIVITAS KOMPOSISI MEDIA YANG BERBEDA DALAM PENGGUNAAN ALAT FILTER AIR SEDERHANA.
