Abstract

This article discusses the performance analysis of the CFM56-3-B1 turbofan engine used on the Boeing 737-300 aircraft under various operational conditions. This study was conducted to understand the engine performance under different flight conditions, such as minimum idle, approach idle, maximum continuous, and take off. This study was conducted using a qualitative method using a descriptive approach and literature study. The results of the analysis prove that the performance of the fan, booster, and high-pressure compressor (HPC) is higher than its ideal value due to compressor imbalance and leakage that causes an increase in compression temperature. Furthermore, it was found that during the take-off process the thermal efficiency became high with an actual efficiency of 37%, but still lower than the ideal efficiency of 47%, which was caused by material friction and environmental factors. While the maximum thrust was achieved thanks to the combination of hot and cold nozzle designs. The conclusion shows that engine efficiency is affected by material friction and environmental conditions, which have an impact on reducing thermal efficiency by 9.59%. Suggestions are given to improve thermal efficiency and thrust by optimizing airflow and engine cooling.

Abstract

This study aims to analyze the influence of sharia governance and reputation on customer loyalty at Bank Riau Kepri Syariah, both partially and simultaneously. In an effort to maintain customer loyalty, Islamic banks must continuously improve their corporate governance systems to remain competitive compared to other banks. Additionally, Islamic banks are obligated to comply with sharia principles in their instruments, products, operations, practices, and management. This research employs a quantitative approach by distributing questionnaires to 100 customers. The data were analyzed using linear regression methods with the assistance of IBM-Statistic software. The results indicate that both sharia governance and reputation variables, individually and collectively, have a positive and significant impact on customer loyalty. These findings suggest that the implementation of good sharia governance and a positive reputation can enhance customer loyalty at Bank Riau Kepri Syariah.
