This study aims to analyze the effect of corporate communication and service quality on loyalty mediating satisfaction. The population of this study is 384 Islamic bank customers in North Sumatra. This research is quantitative research using the survey method. The number of research samples was 384 customers. Characteristics of this research sample were (1) Savings customers who actively carried out transactions in Islamic banks (2) Savings customers who had used bank services for at least 1 year (3) Savings customers who used services directly and individually. The data analysis technique used in this study was the Partial Least Squares-Structural Equation Model (SEM-PLS) analysis technique, using Warp-PLS 3.0 software. This study investigates the largest Islamic banks in North Sumatra, namely Bank Syariah Mandiri, Bank BNI Syariah, and Bank BRI Syariah. The results show that company communication has a positive and significant effect on satisfaction, service quality has a positive and significant effect on satisfaction, company communication has a positive and significant effect on loyalty, service quality has a positive and significant effect on loyalty, satisfaction has a positive and significant effect on loyalty. There is also a significant effect of satisfaction on the relationship between company communication and loyalty, and the relationship between service quality and loyalty. This study contributes to Islamic banking to increase customer loyalty.

Abstract A new series of double perovskite oxides Sr2Fe1-xTixNbO6-δ (x = 0, 0.05 & 0.1) were prepared by traditional solid state reaction method and characterized by X-ray diffraction, scanning electron microscope (SEM), energy dispersive x-ray (EDX), ac impedance and dc four point using Van Der Pauw method. The samples were sintered at 1200 °C for 12 h in air to get single phase. Rietveld refinement shows that all composition crystallizes in tetragonal symmetry in the space group I4/m. The lattice parameter were related to the ideal single perovskite ap as a ≈ b ≈ √2ap, and c ≈ 2ap. Scanning electron microscope shows increase in porosity with increase of Ti content. Sr2Fe1-xTixNbO6-δ/YSZ shows a good interface with no lamination problem between the two materials. EDX shows that the element contents of the materials synthesized in this study close to the nominal stoichiometry. Chemical compatibility studies with YSZ electrolyte shows no reaction with the anode. A symmetrical cell with the configuration of Sr2Fe1-xTixNbO6-δ|YSZ|Sr2Fe1-xTixNbO6-δ (x = 0.05 & 0.1) shows the lowest polarization resistance of 49.80 Ω cm2 and the highest ac conductivity of 3.57 × 10−3 S cm−1 in dry H2/Ar for x = 0.1. The activation energy was found to be 1.20 eV which is almost similar to Sr2FeNbO6-δ as reported in literature. The dc conductivity measurement was highest for SFTN0.1 at 750 °C in dry 5% H2/Ar with a value of 1.17 S cm−1. Highlights <UL> <LI> Titanium was substituted for Iron in the mixed conducting perovskite oxide SFN. </LI> <LI> A single double perovskite phase was obtained in air. </LI> <LI> Titanium substitution improves porosity, a.c conductivity and area specific resistance. </LI> <LI> The enhancement has been explained by a simple defect chemistry model. </LI> <LI> Electrochemical performance are interesting for applicability as an SOFC anode material. </LI> </UL>
