Abstract
This study addresses ergonomic risks faced by firefighters during hose rolling activities, a physically demanding task that can lead to musculoskeletal issues. Building on a previous project conducted at the Bukit Gambir Fire and Rescue Station, this research expands the analysis by comparing four different hose rolling postures: roll and coil, dutch roll, flaking, and figure of eight. The Rapid Entire Body Assessment (REBA) method was used to evaluate the ergonomic risk levels of each posture. To further enhance firefighter safety, a preventive strategy tool was proposed and developed. The tool’s design was tested using Finite Element Analysis (FEA) in SolidWorks to assess the structural performance of its alloy steel hook and shaft under load. Simulation results showed stress levels below the material’s yield strength, and factor of safety (FOS) analysis confirmed the tool’s structural reliability. This project takes a holistic approach to understanding and mitigating ergonomic risks in firefighting. This study found that the structural of an assistive tool is safe and confirming the robustness and reliability of both the hook and alloy steel shaft designs. By combining ergonomic assessment with engineering simulation, it not only identifies high-risk postures but also provides a practical solution to reduce strain and prevent injury. Ultimately, the project contributes to improving the safety and well-being of firefighters, supporting a safer work environment for those who risk their lives to protect others.

Abstract
Leadership is an important factor in the social relationships of line in the workplace. Consider as the main factor that affects and forms group behavior in every organization known since the time of ancient. Practically, it involves employees who appreciate the feeling of a strong commitment to accomplishing organizational goals and long-term objectives inside the company. The objective of this study was to determine the influence of micromanagement leadership style on employee perception on job satisfaction in the manufacturing industry at Malacca. Thus, leadership styles can fortunately, influence or greatly affect job satisfaction in workplace performance. Micromanagement leadership style has comparatively more negative effects on an employee’s behavior and commitment towards the effort in the workplace. This creates a sense of perceived stress managing to behave in an ineffective approach. A descriptive study was used to understand employee perceptions of micromanage leadership styles that affect job satisfaction. A total of 97 respondents among manager level from the Malacca state of Malaysia’s manufacturing industry was collected with the level of manager’s range 27 to 55 years of age. Situational leadership theory conducted this study to discover how a micromanaged leadership style influences employee perception that impacts an employee’s job satisfaction. The primary research question focused on positive and negative employee perceptions related to managers’ leadership behaviors and attributes. The study found that employee perception by micromanaging leadership style affects an employee’s job satisfaction with the correlation coefficient between overall job satisfaction and main factors for job satisfaction recognition at work and personal growth were (0.79) and (0.85) respectively. There were statistically significant differences in age group, working experience and position (P<0.05). The result showed Cronbach alpha 0.708 internal consistency acceptable affect the variables. Micromanagement had reduced productivity, lower morality, loss of trust, less teamwork involvement, less personal growth and reduced innovation. Therefore, consideration of an employee's knowledge, skills, experience, attitude, and motivation is essential for job satisfaction to enhance high productivity and efficiency.
