A product containing pork cannot be consumed by Muslims. A surface plasmon resonance (SPR) biosensor using a silver nanoparticle base was developed to analyze the hemoglobin content of porcine in silico using the molecular docking method. The variation of the thin layer system on the SPR by adding a layer of silver nanoparticles can increase the selectivity and sensitivity of the SPR biosensor. The surface of silver nanoparticles has a high sensitivity plasmon resonance spectra, so it can be used as a detector. The smaller the gibbs free bond energy (∆G), the stronger the bond stability between silver nanoparticles (AgNPs) with porcine and bovine hemoglobin protein receptors. Silver nanoparticles with an amount of 10 Ag had the lowest Gibbs free binding energy values for the two receptor proteins, -2.04 kcal/mol in porcine hemoglobin protein and -2.18 Kcal/mol in bovine. In order to function as sensors in SPR biosensors, silver nanoparticles must be more sensitive to porcine hemoglobin protein than bovine hemoglobin (∆G porcine
