This research aims to construct hydrotalcite Mg-Al-CO 3 by tuning the pH synthesis and molar ratio. The tuning was carried out by applying different synthesis pH. In addition, utilization of snail shell waste is expected to replace CO 3 2- ion that needed for anion component in hydrotalcite production. For this study precipitation and hydrothermal methods were applied for synthesis. The precipitation had been carried out in three steps, namely isolation of ion CO 3 2- from snail shell, preparation of Na 2 CO 3 solution using snail shell powder as ion CO 3 2- source and synthesizing hydrotalcite, where hydrothermal method was carried out at 150 °C. Confirmation of hydrotalcite obtained was done using SEM and FTIR.
