Abstract
Air merupakan sumber daya alam yang sangat penting bagi kehidupan. Selain digunakan untuk memenuhi kebutuhan hidup, air juga dapat bermanfaat dalam bidang industri. Akan tetapi, semakin lama berbagai kegiatan yang dilakukan manusia menyebabkan polusi pada air laut. Oleh karena itu, diperlukan teknologi yang tepat untuk mengatasi masalah tersebut yaitu dengan seawater reverse osmosis. Alat ini menggunakan metode penyaringan berbagai molekul besar dan ion – ion dari suatu larutan dengan cara memberi tekanan pada larutan tersebut hingga melewati membran semipermeabel. Monitoring flow digunakan untuk mengetahui laju aliran yang akan memasuki membran semipermeabel. Laju aliran akan dipengaruhi oleh tekanan yang dihasilkan oleh booster pump, semakin besar tekanan maka semakin besar pula laju aliran yang dihasilkan. Berdasarkan data yang telah dan diolah dengan persamaan kalibrasi didapatkan nilai standart deviasi maksimum sebesar 0,05696 L/Jam, ketidakpastian type A1 sebesar 0,2321 L/Jam, akurasi pembacaan sensor sebesar 2,21755 dan ketidakpastian diperluas atau Uexp sebesar 2,360 L/Jam

Water is a natural resource that very important for life.in addition used for fulfill the needs of live, water also can be a useful tool in the field of industry. However, the longer of various humans activities causing pollutants in seawater. Therefore, technology that required right for solve the problem is seawater reverse osmosis. This equipment is using the method of filtration of various big molecule and ion from a solution with pressure on solution. Until pass through a semipermiable membrane. Monitoring flow used to know flow rate that will enter into semipermiable membrane. Flow rate will be influenced by pressure that produced by booster pump, bigger pressure then bigger flow rate is produced. Based on data that have been processed with calibration equations obtained maximum standard deviation value 0,05696 L/H, uncertainty type A1 0,2321 L/H, sensor acuration is 2,21755 L/H, and uncertainty expand is 2,360 L/H
