ABSTRAK
Dalam rangka mendukung akselerasi pertumbuhan dan cross selling transaction serta memperkuat posisi BUMN dalam menghadapi persaingan bebas dan era globalisasi, diperlukan sinergi BUMN di segala lini. Salah satu bentuk sinergi tersebut adalah sinergi transaksional dimana sumber pembiayaannya berasal dari bank umum syariah perusahaan anak BUMN. Berdasarkan hasil penelitian, disimpulkan bahwa frekuensi dan nilai transaksi sinergi BUMN berpengaruh signifikan secara bersama-sama terhadap Financing to Debt Ratio FDR dan Non Performing Financing NPF bank umum syariah perusahaan anak BUMN. Secara parsial, dari sisi pengaruhnya terhadap FDR: semakin banyak number of account sinergi transaksional BUMN, semakin tinggi FDR bank umum syariah perusahaan anak BUMN. Semakin besar nilai sinergi transaksional BUMN, semakin rendah FDR bank umum syariah perusahaan anak BUMN. Secara parsial, dari sisi pengaruhnya terhadap NPF: semakin banyak number of account sinergi transaksional BUMN, semakin tinggi NPF bank umum syariah perusahaan anak BUMN. Semakin besar nilai sinergi transaksional BUMN, semakin tinggi NPF bank umum syariah perusahaan anak BUMN. Dalam pelaksanaan sinergi transaksional tersebut, PT BNI S berada pada batas efisiensi, sedangkan PT BSM dan PT BRIS tidak efisien.
