Penelitian ini bertujuan untuk mengkaji pengaruh Perceptions of Politics (POP) terhadap Knowledge Sharing (KS), serta peran Islamic Work Ethics (IWE) sebagai variabel independen dan moderator dalam konteks organisasi berbasis nilai. Studi dilakukan pada PT Bank Riau Kepri Syariah (BRKS) menggunakan pendekatan kuantitatif dengan metode Partial Least Squares Structural Equation Modeling (PLS-SEM) dan melibatkan 144 responden. Hasil analisis menunjukkan bahwa POP berpengaruh negatif dan signifikan terhadap KS, yang mendukung teori sebelumnya mengenai dampak persepsi politik terhadap perilaku prososial. Sementara itu, pengaruh langsung IWE terhadap KS serta peran moderasinya terhadap hubungan POP-KS tidak signifikan secara statistik. Temuan ini diposisikan sebagai eksploratif dan indikatif, mengingat keterbatasan validitas konstruk IWE yang belum optimal. Penelitian ini memberikan kontribusi awal terhadap literatur mengenai dinamika politik organisasi dan nilai kerja Islam di institusi keuangan syariah. Temuan-temuan yang tidak signifikan dianalisis secara hati-hati dan tidak dijadikan dasar untuk kesimpulan final, melainkan mendorong dilakukannya studi lanjutan dengan instrumen dan pendekatan yang lebih kuat untuk menguji hubungan antarvariabel secara lebih meyakinkan.

This study aims to examine the influence of Perceptions of Politics (POP) on Knowledge Sharing (KS), with Islamic Work Ethics (IWE) assessed both as an independent variable and a moderator, within the value-based context of PT Bank Riau Kepri Syariah (BRKS). Using a quantitative approach, data were collected from 144 employees and analyzed through Partial Least Squares Structural Equation Modeling (PLS-SEM). The results reveal that POP has a significant negative effect on KS, aligning with existing theories that political perceptions undermine trust and prosocial behavior in the workplace. However, the direct effect of IWE on KS and its moderating role in the POP–KS relationship were found to be statistically insignificant. These findings are treated as exploratory and indicative, given that the IWE construct exhibited limited convergent validity and internal consistency. While only one of the three hypotheses was statistically supported, this study offers an initial empirical contribution to understanding how organizational politics and Islamic ethical values relate to knowledge-sharing behavior in Islamic financial institutions. Non-significant results are interpreted with caution and are not positioned as final conclusions, but rather as a basis for future research that may employ more robust instruments and methodological designs.
