Abstract
Air yang terdapat pada wilayah pesisir memiliki karakteristik sebagai air payau. Air tersebut terjadi karena adanya intrusi dari air laut menuju air tawar. Kebutuhan akan air tawar juga dialami oleh masyarakat pesisir. Oleh sebab itu, dibutuhkan proses pengolahan air payau menjadi air tawar. Proses desalinasi air payau menjadi air tawar pada penelitian ini menggunakan teknologi reverse osmosis. Kebutuhan air manusia tidak hanya air tawar, melainkan air yang layak untuk dikonsumsi. Air tawar apabila langsung dikonsumsi akan menyebabkan masalah pencernaan. Pada penelitian ini mengolah air hasil dari desalinasi reverse osmosis untuk dijadikan air minum sesuai baku mutu air minum yang diisyaratkan oleh Permenkes 492/2010. Melalui beberapa variasi media filter organik (alam). Diantaranya karbon aktif, manganese zeolit, pasir silika dan kerikil sebagai filter organik. Membran keramik yang dilapisi oleh perak koloid didalamnya dapat berfungsi sebagai desinfektan bakteri dari air yang melalui membran keramik. Variabel yang digunakan yakni F1 (filter organik), F2 (Filter organik + membran keramik) dan F3 (membran keramik). Ditinjau berdasar efisiensi filtrasi TDS, Reaktor F1 12,16%, reaktor F2 8,56% dan reaktor F3 4,5%. Sedangkan nilai pH, keseluruhan variabel reaktor meningkatkan pada angka 7-7,5. Pada penelitian ini merupakan satu rangkaian dengan solar collector dan recirculation reverse osmosis. Variabel yang digunakan rangkaian adalah suhu 310C, 350C dan 400C. Dilakukan beberapa percobaan yang membandingkan variabel post treatment dan variabel rangkaian. Didapatkan filtrasi reaktor F2 pada suhu 310C menunjukkan hasil optimal. Sehingga air hasil filtrasi reaktor tersebut diujikan pada laboratorium. Hasil yang dari pengujian air sampel tersebut masih menunjukkan bahwa air sampel hasil penelitian masih belum diterima baku mutu air minum dikarenakan masih terdapat bakteri E.coli dan bakteri koliform dengan nilai 1 x 103 CFU/100ml. Sedangkan parameter wajib lain diterima baku mutu air minum. Sedangkan kemampuan reaktor post treatment dalam filtrasi garam mineral pada percobaan menunjukkan efisiensi hasil rejeksi pada reaktor F1 84%, reaktor F2 sebesar 100% dan reaktor F3 sebesar 100%.

Water contained in coastal areas has characteristics as brackish water. The water occurs because of intrusion from sea water into fresh water. The need for fresh water is also experienced by coastal communities. Therefore, brackish water treatment process is needed to become fresh water. Brackish water desalination process into fresh water in this study uses reverse osmosis technology. Human water needs are not only fresh water, but water that is suitable for consumption. Fresh water if consumed directly will cause digestive problems. In this study, treating water resulting from reverse osmosis desalination to be used as drinking water according to drinking water quality standards as required by Permenkes 492/2010. Through several variations of organic (natural) filter media. Among them activated carbon, manganese zeolite, silica sand and gravel as an organic filter. Ceramic membrane coated by colloid silver inside can function as a bacterial disinfectant from water through a ceramic membrane. The variables used are F1 (organic filter), F2 (organic filter + ceramic membrane) and F3 (ceramic membrane). Based on TDS filtration efficiency, F1 Reactor is 12.16%, F2 reactor is 8.56% and F3 reactor is 4.5%. While the pH value, the overall variable reactor increases in number 7-7,5. In this study is a series with solar collector and reverse osmosis recirculation. The variables used in the circuit are temperature 310C, 350C and 400C. Several experiments were conducted comparing post-treatment variables and series variables. F2 reactor filtration obtained at a temperature of 310C shows optimal results. So that the reactor's filtration water is tested on a laboratory. The results of the sample water test still showed that the sample water from the study results was not yet accepted the drinking water quality standard because there were still E. coli and coliform bacteria with a value of 1 x 103 CFU / 100ml. While other mandatory parameters are accepted drinking water quality standards. While the ability of the post treatment reactor in mineral salt filtration in the experiments showed the efficiency of the rejection results in the F1 reactor at 84%, the F2 reactor at 100% and the F3 reactor at 100%.
