Magnesium silicate is a composite material consisting of two main raw materials namely magnesium oxide (MgO) and silica (SiO2) in the form of white powder, amorph, odorless and insoluble in water. The purpose of this study was to examine the effect of bittern addition and the effect of time on the quality of Magnesium Silicate. From the XRF analysis, it was found that MgSiO3 product had 16% MgO content and 59.1% SiO2, pH 9. The production of magnesium silicate can be made by several methods such as extraction and precipitation methods. Formation of sodium silicate (Na2SiO3) was obtained from the process of extracting geothermal sludge containing (SiO2) of 100 grams with 1N NaOH solution at 100 ºC for 90 minutes. Formation of magnesium silicate (MgSiO3) is processed by adding bittern containing magnesium (Mg) to sodium silicate solution (Na2SiO3). MgSiO3 product with the best precipitation time at 90 minutes with a ratio of Na2SiO3: bittern 1: 1½. So the addition of bittern and precipitation time affect the quality of Magnesium silicate
