The synthesis of mesoporous silica-alumina from Na2SiO3 and NaAlO2 solutions extracted from lapindomud using mesoporous gelatin templates from catfish bone extract has been performed. Mesoporoussilica-alumina (MSA) synthesis was carried out by sol-gel method with a gelatin template of catfishbone for as much as 0.0; 0.5; 1.0 and 1.5 g, which produced MSA-G00, MSA-G05, MSA-G10 andMSA-G15, respectively. The obtained MSA was analyzed using FTIR, XRD, TEM and surface areaanalyzer (BET and BJH methods). The MSA-G00, MSA-G05, MSA-G10 and MSA-G15 showed aspecific surface areas of 24.58, 41.73, 59.73, 89.82 m2/g and pore diameters of 10.20, 3.86, 9.97, and7.31 nm, respectively. The XRD results proved that all the MSA were amorphous while the TEManalysis showed that all prepared MSAs using gelatin as a template were wormhole-like pores
