Abstract
Ketersediaan air di Indonesia mencapai 15.500 m3 per kapita per
tahun. Angka ini masih jauh di atas ketersediaan air rata-rata di dunia
yang hanya 8.000 m3 per tahun. Hal ini dikarenakan air payau di
daerah pesisir memeiliki kandungan natrium klorida (NaCl) yang tinggi
sehingga menyebabkan rasa asin yang berlebih. Air payau disebabkan
oleh adanya intrusi air laut ke jalur air tanah. Peristiwa inilah yang
menyebabkan tingginya kadar garam air sumur di daerah pesisir.
Pembuatan prototipe ini terdiri dari perancangan prototipe,
persiapan pembuatan sampel, pembuatan prototipe, dan pengolahan
sampel. Pengolahan air payau ini terdiri dari tiga proses, yaitu filtrasi,
aerasi, dan pancaran sinar UV. Produk yang dihasilkan, selanjutnya
dianalisa pada parameter DO, pH, salinitas, TDS, turbidity, ferro,
mikroorganisme dan total hardness.
Keefektifan REBWAR terbaik terjadi pada penggunaan antrasit,
zeolit, resin kation dan resin anion sebagai adsorben dengan tanpa
aerasi. Hasil analisa pada proses optimum ini adalah persentase
penurunan turbidity sebesar 60,94%, kadar TDS sebesar 70,69%, kadar
total hardness sebesar 44,92%, kadar ferro sebesar 93,29%, salinitas
sebesar 71,43%, dan persentase kenaikan kadar DO sebesar 47,21%,
serta mempunyai nilai pH sebesar 7,58. Pada pengamatan analisis
mikroorganisme, air produk REBWAR layak dan memenuhi syarat
kesehatan dikarenakan tidak ada mikroorganisme yang berada pada
kandungan air. Hal ini dikarenakan keefektifan sinar lampu UV yang
digunakan untuk mengolah air payau menjadi bahan baku air minum.

The availability of water in Indonesia reaches 15.500 m3 per
capita per year. This figure is far above the average water availability
in the world which is only about 8.000 m3 per year. This is due to the
brackish water in coastal areas contains high sodium chloride (NaCl),
causing excessive saltiness. Brackish water is in consequence of the
intrusion of seawater into groundwater pathway.
Main prosedure to produce this prototype consists of designing
prototype, preparing sample, making prototype and treating sample.
Brackish water treatment consists of three processes, namely filtration,
aeration, and UV rays. Water is produced, and then analyzed to
measure parameters, which are DO, pH, salinity, TDS, turbidity, ferro,
microorganisms and total hardness.
The best effectiveness of REBWAR occurred in the use of
anthracite, zeolite, cation resin and anion resin as an adsorbent without
aeration. Analysis result of this optimum process is reduction
percentage of turbidity is 60.94%, TDS level of 70.69%, total hardness
level of 44.92%, ferrous level of 93.29%, salinity of 71.43%, and
increase percentage of DO level is 47.21% and has pH value at 7,58. In
observation of the microorganisms analysis, REBWAR product is
qualified and fulfills health requirement because there isn’t
microorganisms residing on water content. This is due to the
effectiveness of UV light rays are used to treat brackish water into
drinking water.
