Abstract

  Perbankan syariah harus mampu mempertahankan keunggulan kompetitif dengan cara meningkatkan dan mempertahankan kualitas layanannya, memenuhi kebutuhan nasabah dan menumbuhkan loyalitas nasabah. Kepuasan merupakan salah satu faktor yang membuat nasabah setia kepada perbankan. Seorang nasabah pasti akan melakukan transaksi terhadap suatu produk atau jasa secara berulang kali jika mereka merasa puas dengan produk atau jasa tersebut. Disisi lain gender menjadi salah satu faktor yang mungkin berdampak pada perilaku konsumen. Tujuan penelitian ini untuk mengetahui pengaruh service quality dan relationship quality terhadap customer loyalty melalui customer satisfaction dengan gender sebagai variabel moderasi. Populasi yang digunakan dalam penelitian ini adalah nasabah Bank Syariah Indonesia di Malang Raya. Sampel penelitian ini berjumlah 250 responden. Penelitian ini menggunakan pendekatan SEM-PLS dengan software SmartPLS. Hasil penelitian menunjukkan bahwa service quality, relationship quality dan customer satisfaction berpengaruh signifikan terhadap customer loyalty. Lebih lanjut, service quality dan relationship quality berpengaruh signifikan terhadap customer satisfaction. Lebih lanjut, keberadaan customer satisfaction mampu memediasi service quality dan relationship quality terhadap customer loyalty. Untuk pengaruh moderasi, gender tidak mampu memoderasi pengaruh service quality dan relationship quality terhadap customer loyalty. Berdasarkan hal tersebut, keberadaan customer satisfaction mampu meningkatkan customer loyalty. Kemudian pihak bank tidak perlu mengkhawatirkan terkait dengan gender, karena dalam hal ini gender tidak mampu memoderasi customer loyalty.

Abstract

Bank syariah harus mampu membangun kepercayaan nasabah terhadap praktik keberlanjutan yang mereka terapkan. Bank syariah juga disarankan untuk meningkatkan transparansi dan komunikasi terkait inisiatif keberlanjutan yang dilakukan perbankan. Penelitian ini bertujuan untuk menganalisis pengaruh praktik ramah lingkungan dan kepercayaan ramah lingkungan terhadap loyalitas ramah lingkungan melalui variabel kepuasan ramah lingkungan, dengan gender sebagai variabel moderasi. Sampel penelitian terdiri dari 200 nasabah perbankan syariah dengan menggunakan metode simple random sampling dalam pengambilan sampel yang kemudian dianalisis dengan teknik Structural Equation Modeling—Partial Least Square (SEM-PLS). Hasil penelitian menunjukkan bahwa praktik hijau berpengaruh positif namun tidak signifikan terhadap loyalitas hijau, sedangkan kepercayaan hijau berpengaruh positif dan signifikan terhadap loyalitas hijau. Praktik ramah lingkungan dan kepercayaan ramah lingkungan juga berpengaruh positif dan signifikan terhadap kepuasan lingkungan hidup. Selanjutnya green satisfaction berpengaruh positif dan signifikan terhadap green loyalty. Kepuasan ramah lingkungan terbukti memediasi pengaruh praktik ramah lingkungan dan kepercayaan ramah lingkungan terhadap loyalitas ramah lingkungan. Sementara itu, gender tidak terbukti memoderasi hubungan antara praktik ramah lingkungan dengan kepercayaan ramah lingkungan dan loyalitas ramah lingkungan. Perbankan syariah perlu meningkatkan penerapan praktik berkelanjutan, membangun kepercayaan nasabah, dan meningkatkan kepuasan nasabah dengan praktik berkelanjutan untuk memperkuat loyalitas ramah lingkungan.

Abstract

This study examines the impact of sukuk on inflation in Indonesia, considering the interplay of macroeconomic factors during the post-COVID-19 recovery period. Employing a time series linear model (TSLM) with monthly data from January 2019 to March 2024, we investigate the relationship between sukuk outstanding and inflation (Consumer Price Index), controlling for industrial production, exchange rate, interest rate, and Composite Leading Indicator (CLI). Results reveal a significant positive relationship between sukuk and inflation, suggesting that increased sukuk outstanding is associated with higher inflation rates. This finding contributes to the existing literature by providing empirical evidence of the inflationary impact of sukuk in Indonesia, especially in the context of post-pandemic recovery. The study also identifies significant positive relationships between inflation and interest rate, as well as inflation and CLI, highlighting their roles in driving inflation. While the exchange rate also exhibits a positive relationship with inflation, industrial production shows a negative association, suggesting a potential dampening effect on inflation. The model demonstrates strong explanatory power, with an adjusted R-squared of 0.9818, indicating that the included variables effectively capture the variation in inflation. These findings offer valuable insights for policymakers in formulating effective inflation management strategies and ensuring macroeconomic stability in Indonesia's post-pandemic recovery.

Abstract

Sharia Rural Banks in East Java provide essential financial services in compliance with Islamic law, fostering economic growth in rural communities. Assessing their hazard rate, which indicates the probability of bank failure over time, is crucial for understanding their stability and resilience amidst various economic and regulatory challenges. Therefore, this study aimed to determine the susceptibility opportunities of each BPRS. The second objective is to find out the financial ratios that cause it. The financial sustainability measure is a measuring tool to calculate the chance of survival. Financial sustainability approximates the value of Financial Self-Sufficiency (FSS). The population used is BPRS in East Java. The analysis technique used survival analysis and multiple period logit models Research variables that invariably affect the sustainability of BPRS include NPF, ROA, Bank Size, PM, FR, GLP, WoR, and LDR. The study on Sharia Rural Banks (BPRS) in East Java reveals that only about 30% of these banks have a stable financial condition, indicating a low overall sustainability rate. This suggests that the majority of BPRS need to improve their financial health to better support regional economic development and the growth of MSMEs.

Abstract

To ensure the financial stability of Indonesian banks, especially Sharia banks, it is essential to focus on various factors and elements. This study investigates the endogenous and exogenous factors influencing the financial stability of Sharia banks in Indonesia. The study utilized data from the annual financial statements of Sharia banks in Indonesia spanning from 2010 to 2021. Panel data regression served as the analytical tool for the research. The findings indicate that the stability of Sharia commercial banks in Indonesia is influenced by both capital structure and credit risk. Financial leverage also affects sharia bank’s financial stability. While ownership distinguishes a bank in terms of organizational structure, it does not necessarily guarantee stability. Islamic commercial banks remain stable amid the COVID-19 pandemic, showing no significant impact on their overall stability. These findings will enhance bank understanding of the risks faced by banks and form the basis for new regulatory efforts to strengthen overall risk management, including liquidity risk and credit risk.

Abstract

The objective of this study is to examine the relationship between various factors and the performance of Islamic commercial banks in Indonesia over the next 12 periods. The variables considered include Non-Performing Assets, Capital Adequacy Ratio, Insolvency-risk, Inflation, Financial Technology, and Bank Size. The research methodology employed is a quantitative approach with a descriptive analysis. The sampling technique utilized is saturated sampling, resulting in a total of 96 data points. The findings indicate that the Non-Performing Assets (NPA) variable has a significant impact on Return on Assets (ROA), while the ROA variable does not significantly affect the NPA variable. Additionally, the inflation variable does not have a statistically significant effect on ROA, and vice versa. In the short term, the variables that influence bank performance are NPA, Capital Adequacy Ratio, Insolvency-risk, Financial Technology, and Bank Size. In the long term, significant factors influencing bank performance are NPA, Insolvency-risk, Financial Technology, and Bank Size. The Impulse Response Function (IRF) test demonstrates that ROA shows a positive response to the impact of NPA, Capital Adequacy Ratio, Inflation, Financial Technology, and Bank Size, while it exhibits a negative response to shocks caused by inflation. Throughout the study period, the variable with the greatest contribution remains Financial Technology, followed by other variables. Ultimately, the aim of this study is to provide insights for future policy implementation and decision-making within companies
