      Abstract
      Meat Bone Meal (MBM) adalah bahan pakan yang memiliki sumber protein, energi, dan mineral yang baik untuk hewan. Pakan MBM diperoleh dari olahan produk samping hewan ternak yang mudah untuk dicampur dengan bahan yang berasal dari produk babi. Importir atau produsen lokal yang curang dapat mencampurkan produk babi ke dalam MBM karena produk babi memiliki harga yang relatif murah dan dapat ditemukan di beberapa negara. Penelitian ini bertujuan untuk mengidentifikasi fragmen DNA babi pada sampel MBM menggunakan metode Real Time Polymerase Chain Reaction (qPCR). Proses identifikasi fragmen DNA babi pada sampel MBM dimulai dari ekstraksi DNA, kuantifikasi DNA (nilai konsentrasi dan kemurnian) dengan spektrofotometer 2000c, dan amplifikasi DNA dengan qPCR berbasis probe. Proses identifikasi DNA babi pada sampel MBM dideteksi menggunakan kit komersial Mericon Pig Kit dengan primer dan probenya sudah termasuk di dalam master mix spesifik. Hasil penelitian menunjukkan bahwa 81 sampel dari 198 sampel MBM teridentifikasi mengandung DNA babi. Sampel DNA babi yang positif dapat diketahui dengan nilai cycle threshold (Ct<45) pada hasil amplifikasi qPCR. Real time PCR dapat dijadikan sebagai metode pengujian untuk mengidentifikasi keberadaan fragmen DNA babi pada sampel MBM.
       
      Meat and bone meal (MBM) is a valuable source of protein, energy, and minerals in animal feed production. The MBM feed is obtained from livestock by-products that are easily mixed with pig products. Fraudulent importers or local producers can mix pig products into MBM because they are relatively inexpensive and can be found in several countries. This research aim was to identify pig DNA fragment in MBM samples using Real Time Polymerase Chain Reaction (qPCR). The process of identifying porcine DNA fragments in MBM samples was started from DNA extraction, DNA quantification (concentration and purity values) with spectrofotometer 2000c, and DNA amplification with qPCR based on probes. The process of detection porcine DNA in MBM samples was used a commercial Mericon Pig kit which the primer and probe were inserted into a specific master mix. The results showed that 81 samples were positive for porcine DNA from 198 samples of MBM. Positive samples of porcine DNA can be identified by cycle threshold value (Ct<45) on the result of amplification qPCR. Real time PCR methods can be used to identify the presence of porcine DNA in MBM samples.
