Hasil pengamatan secara fisik pada air sungai Amandit menujukan kekeruhan akan meningkat saat musim hujan, sebaliknya saat musim kemarau kekeruhan air sungai cenderung menurun. Tujuan penelitian ini untuk mengetahui tingkat kekeruhan sebelum dan sesudah, debit, waktu kontak, serta ketebalan efektif pasir.
Jenis penelitian yaitu eksperiment dengan post test only with control group design, dengan 4 variasi dan 6 kali pengulangan. Variasi SPL 1 adalah ketebalan pasir 60 cm, SPL 2 ketebalan pasir 70 cm, SPL 3 ketebalan pasir 80 cm, dan SPL 0 tanpa saringan pasir lambat. Adapun ketebalan kerikil sama rata 30 cm.
Hasil penelitian menunjukkan tingkat kekeruhan air baku Sungai Amandit sebelum perlakuan rerata 139,8 NTU. Maka untuk kekeruhan > 50 NTU berdasarkan kriteria saringan pasir lambat (SPL) diperlukan pengolahan pendahuluan berupa proses pra sedimentasi selama 8 jam. Hasil uji coba pasca pra sedimentasi variasi perlakuan ketebalan pasir diperoleh data SPL 0 rerata 45,97 NTU; SPL 1 rerata 14,5 NTU; SPL 2 rerata 8,7 NTU; dan SPL 3 rerata 7,2 NTU. Berdasarkan hasil tersebut, efektivitas diperoleh pada SPL 3 dengan presentase penurunan sebesar 84,5%.
Saringan pasir lambat ini dapat digunakan menjadi alternatif pengolahan sungai menjadi air bersih yang murah, khususnya masyarakat yang tinggal di bantaran sungai dengan memperhatikan kriteria saringan pasir lambat dan tingkat kekeruhan air baku.

THE EFFECTIVENESS OF SLOW SAND FILTER ON REDUCING THE TURBIDITY WATER OF AMANDITE RIVER
(Hardiono, S.KM, M.Kes dan Sulaiman Hamzani, S.T., M.T)

The results of physical observations on the water of the Amandit river show that the turbidity will increase during the rainy season, on the contrary during the dry season the turbidity of the river water tends to decrease. The purpose of this study was to determine the level of turbidity before and after, discharge, contact time, and the effective thickness of the sand.
The results showed that the turbidity level of the Amandit River raw water before treatment was an average of 139.8 NTU. So for turbidity > 50 NTU based on the slow sand filter (SPL) criteria, preliminary processing is required in the form of a pre-sedimentation process for 8 hours. The results of the post-pre-sedimentation trial of variations in sand thickness treatment obtained SPL 0 data with an average of 45.97 NTU; SPL 1 average 14.5 NTU; SPL 2 averaged 8.7 NTU; and SPL 3 average 7.2 NTU. Based on these results, the effectiveness is obtained at SPL 3 with a decrease percentage of 84.5%.
This slow sand filter can be used as an alternative for processing rivers into cheap clean water, especially for people living on riverbanks by paying attention to the criteria for slow sand filters and the level of turbidity of raw water.
