Synthesis of silica-alumina mesoporous with the material based on Lapindo mud by template gelatin from catfish bones using the sol-gel method has been performed. Lapindo mud contains Al and Si as much as 48.8 and 22.6 % so can be leached. The leaching by HCl 6 M and NaOH 6M obtained dissolved Al and Si were 30,938 and 62,300 mg L-1. The gelatin from catfish bones has typed with a molecular weight of 100 kDa. The Mesoporous Si-Al showed that calcination at a temperature of 500°C gave the best porosity with surface area, volume, and pore diameter of 133.076 m2g-1, 0.564 cc g-1, and 9.00 nm, respectively. The amorphous Si-Al character showed at 500°C calcination, but at 600 and 700°C crystals formed from alumina. TEM image showed mesoporous silica-alumina at 500∘C a wormhole pore was formed, while at temperatures 600 and 700°C, there was a decrease in the number of pores so that the surface area of the material becomes small
