Dana Pihak Ketiga (DPK) merupakan sumber utama pendanaan bagi kegiatan operasional perbankan syariah, khususnya dalam penyaluran pembiayaan. Namun, dalam delapan tahun terakhir, perbankan syariah di Indonesia menunjukkan tren perlambatan pertumbuhan DPK. Penelitian ini bertujuan untuk menganalisis pengaruh Global Economic Policy Uncertainty (GEPU) dan indikator makroekonomi, yang meliputi BI 7 – Day Reverse Repo Rate (BI7DRR), Inflasi, dan Indeks Produksi Industri (IPI), terhadap DPK perbankan syariah di Indonesia periode 2017-2024. Penelitian ini menggunakan pendekatan kuantitatif dengan populasi sebanyak 33 entitas perbankan syariah di Indonesia, yang terdiri atas 13 bank umum syariah (BUS) dan 20 unit usaha syariah (UUS), di mana pemilihan sampel dilakukan melalui teknik sampling jenuh. Data dianalisis menggunakan regresi linier berganda dengan bantuan software EViews 12. Hasil penelitian menunjukkan bahwa secara parsial, variabel GEPU dan IPI berpengaruh positif dan signifikan terhadap DPK. Sementara itu, BI7DRR berpengaruh positif namun tidak signifikan, sedangkan inflasi berpengaruh negatif dan tidak signifikan terhadap DPK.
 
ABSTRACT:
Third-Party Funds (DPK) are the primary source of funding for the operational activities of Islamic banking, particularly in the distribution of financing. However, over the past eight years, Islamic banks in Indonesia have shown a trend of slowing DPK growth. This study aims to analyze the influence of Global Economic Policy Uncertainty (GEPU) and macroeconomic indicators, which include the BI 7-Day Reverse Repo Rate (BI7DRR), Inflation, and the Industrial Production Index (IPI), on the DPK of Islamic banks in Indonesia for the period 2017–2024. This research uses a quantitative approach with a population of 33 Islamic banking entities in Indonesia, consisting of 13 islamic commercial banks (BUS) and 20 islamic business units (UUS), where the sample selection was carried out using a saturated sampling technique. The data were analyzed using multiple linear regression with the help of EViews 12 software. The results show that, partially, the GEPU and IPI variables have a positive and significant effect on DPK. Meanwhile, BI7DRR has a positive but not significant effect, while inflation has a negative and not significant effect on DPK.
