The experiments were carried out at the acrylic columns having diameter of 7 cm, column height of 19.5 cm, bed height of 13.5 cm and flow rate of 2 gpm/ft2 (310 mL/minute) for 540 minutes. The number of columns used were 3 columns arranged in series and the rice husk used were in their original size (1-2 mm). The influent concentration of Zn metal was 7.62 mg/L. The results showed that the use of column adsorption in series increased the removal efficiency of Zn by rice husks, from 33.21% using 1 column to 51.70% with 3 columns. The adsorption capacity of Zn obtained when using 3 columns in series was 3.542 mg/g. In addition, the use of adsorption columns in series can also prolong the saturation of the adsorbent, thereby extending its service life. The overall research results demonstrated that column the adsorption in series wi...

Jumlah keluarga yang tidak memiliki akses sanitasi di Kelurahan Hutaimbaru pada tahun 2021 sebesar 241 KK dari 920 KK (26,2%). Wilayah ini telah memiliki fasilitas sanitasi berupa MCK umum dan IPAL komunal. Tujuan penelitian adalah untuk meningkatkan akses sanitasi lingkungan bagi masyarakat dengan menentukan strategi pengelolaan air limbah domestik yang sesuai dan tepat untuk diterapkan di wilayah studi.Metode: Penelitian ini adalah penelitian deskriptif dengan mixed methods atau metode kombinasi. Lokasi penelitian di wilayah permukiman pada hulu Sungai Aek Sarupak Kelurahan Hutaimbaru, Kota Padangsidimpuan pada bulan Oktober 2022. Identifikasi kondisi eksisting pengelolaan air limbah domestik dilakukan melalui observasi...
