Research has been conducted to synthesize and characterization composite LAO-TiO 2 based on LAO mass variation and calcination temperature and its application as an adsorbent of lead metal (Pb). Characterization is done using X-Ray Diffraction (XRD) at an angle of 2θ: 5-60° of LAO mass variation for pillarization, which are 2, 3, and 5 with calcination temperature of 200, 250 and 300°C. The testing of the composite LAO-TiO 2 as lead (Pb) metal absorbent using Atomic Absorption Spectroscopy (AAS). The result shows the most significant basal spacing (d-spacing) is on mass variation 5 g (K5) after calcination with temperature 200 10.19 Å. Composite LAO-TiO 2 Application as lead (Pb) metal adsorbent shows the adsorption capacity (Q) obtained ranges from 4.4-4.9 mg/g.
