Abstract

Research Aims: This research aims to identify the influence of MSMEs and non-MSMEs financing diversification, as well as financing restructuring, on non-performing financing (NPF). Methodology: This study utilizes a quantitative research method with secondary data, including Asset Quality Reports and Financial Ratio Reports accessed through the Financial Services Authority (OJK) from 2018 to 2022 for 10 Islamic commercial banks in Indonesia on a quarterly basis. Non-Probability Sampling was used as the sampling technique, and data analysis was conducted using panel regression with the Fixed Effect Model through Eviews 12 software. Research Findings: The empirical results indicate that both MSMEs and non-MSMEs credit diversification do not have a significant impact on reducing credit risk in Islamic banks in Indonesia. However, restructuring has an impact on non-performing financing in Islamic banks in Indonesia. Theoretical Contribution: This study contributes to the literature by examining the relationship between diversification of MSME and non-MSME financing and financing restructuring. With this research, it is hoped that Islamic banks will pay more attention to minimizing problematic financing to maintain the stability of their financial performance. Research limitation and implication: In practical terms, these findings suggest that policymakers may consider implementing a concentration strategy for financing in specific sectors. If diversification is to be continued, further policy adjustments may be necessary.

Abstract

In today's aircraft industry, the flight control system and landing gear system cannot be separated from the role of the hydraulic technology system. As the prime mover of the hydraulic pump or actuator hydraulic system, a permanent magnet synchronous motor (PMSM) is used. This PMSM is a substitute for the role of conventional combustion engines, and PMSM is considered to have several advantages in increasing performance and efficiency. This research will develop a system to find parameter values for Linear Quadratic Gaussian (LQG) controllers in a hydraulic pump system that is installed as a load from PMSM and then observe and analyze the performance of the response of the synchronous motor system, namely in the form of changes in rotor rotation speed, torque electric power, and stator current on the q-axis. The results of the research on the characteristics of the PMSM implemented in the hydraulic pump system show that the LQG controller is more optimal when compared to the observer controller. The LQG controller is known to have a faster transient response, which is indicated by the value of the settling time improvement at no load, namely 116.67% for the observer controller and 364.705% without the controller. Then when the synchronous motor serves the nominal load, the rotational speed of the rotor produced in the steady state becomes 8.29% faster than the observer controller and 74.49% without the controller. This rotor's rotational speed affects the time the actuator needs to extend and retract motion.
