Santur Kota Sawahlunto ditemukan dalam keadaan keruh, berwarna dan
menimbulkan endapan pada penampungan air. Penelitian ini bertujuan untuk
mengetahui apakah ada perbedaan kualitas fisik, bakteriologi, kimia pada air
pemukiman sebelum dan sesudah dilakukan penyaringan di Desa Santur Kota
Sawahlunto Tahun 2024.
Penelitian menggunakan jenis penelitian Eksperimen. Populasi penelitian
ini air pemukiman masyarakat di desa santur bulan Juli 2024, perlakuan dengan
penyaringan kerikil, pasir, arang, ijuk dan busa.
Hasil penelitian menunjukkan rata-rata sebelum dan sesudah penyaringan,
TDS sebelum (316,8) sesudah (222,5), Kekeruhan sebelum (3,125) sesudah (0,00),
Warna sebelum (3,50) sesudah (0,00), E.Coli sebelum (105,8) sesudah (42,63),
pH sebelum (7,35) sesudah (7,07), Fe sebelum (0,32) sesudah (0,07), Mn sebelum
(0,35) sesudah (0,08). Hasil uji paired sampel t test dan uji wilcoxon sign test
diperoleh ada perbedaan kualitas fisik, bakteriologis, kimia pada air pemukiman
sebelum dan sesudah penyaringan dengan p-Value sesudah penyaringan, TDS
(p=0,017), kekeruhan (p=0,000), warna (p=0,000), E.Coli (p=0,816), pH
(p=0,004), Fe (p=0,001), Mn (p=0,093).
Kesimpulannya adalah ada perbedaan kualitas fisik,bakteriologis, kimia
pada air pemukiman sebelum dan sesudah dilakukan penyaringan dengan media
kerikil, pasir, arang, ijuk dan busa. Disarankan penelitian ini dapat sebagai
pertimbangan kebijakan bagi pemerintah dalam pengelolaan air pemukiman.

Water plays a crucial role in life. The condition of residential water in
Santur Village, Sawahlunto City was found to be murky, colored, and causing
sediment in the water storage. This study aims to determine if there are differences
in physical, bacteriological, and chemical quality of residential water before and
after filtration in Santur Village, Sawahlunto City in 2024.
The research uses an experimental design. The study population consists of
residential water in Santur Village in July 2024, with treatments including filtration
using gravel, sand, charcoal, coconut fiber, and foam.
The results showed that, on average, before and after filtration: TDS was
316.8 before and 222.5 after; turbidity was 3.125 before and 0.00 after; color was
3.50 before and 0.00 after; E. coli was 105.8 before and 42.63 after; pH was 7.35
before and 7.07 after; Fe was 0.32 before and 0.07 after; Mn was 0.35 before and
0.08 after. The paired sample t-test and Wilcoxon signed-rank test showed
significant differences in physical, bacteriological, and chemical quality of
residential water before and after filtration with p-values as follows: TDS
(p=0.017), turbidity (p=0.000), color (p=0.000), E. coli (p=0.816), pH (p=0.004),
Fe (p=0.001), Mn (p=0.093).
In conclusion, there are significant differences in the physical,
bacteriological, and chemical quality of residential water before and after filtration
using gravel, sand, charcoal, coconut fiber, and foam. This study is recommended
as a consideration for policy-making by the government in residential water
management.
