    Abstract

    Indonesia was an archipelago country in which 2 / 3 was surrounded by the ocean. Sea water contains many minerals that was useful and there was also elements that harm human beings one of which is Ca2+ ions that cause water hardness. Ions can be removed by using natural zeolite as adsorbtion.This research was expected to utilize zeolite as an absorber to absorb Ca2+ ions contained in seawater causes of hardness so that it can be used and processed further and can be applied on an industrial scale.The method used in this research was batch research. Before the zeolite was used for adsorbent, zeolite first activated using NaOH 1N. Zeolite already active is mixed with seawater and then stirred. The conditions used in this research are the conditions specified amount of sea water, the weight of zeolite and stirring speed. While working conditions are the zeolite particle size and stirring time.Based on the results of research conducted, the best conditions obtained on the zeolite particle size of 100 meshes with 75 minutes of stirring time, producing levels of calcium (Ca2+) of 909.25 mg / liter.
