This study aims to determine the influence of compensation, occupational safety and health, and work motivation on employee job statisfaction. Data were collected using a questionnaire distributed to employees of CV. Rizky Berdikari Mandiri. The sampling technique used was saturated sampling, with a total of 53 respondents. The analytical tool used is descriptive (primary data) by using a questionnaire which is assisted by a likert scale and given to respondents. The analytical tool used is SPSS software version 29. The results of the study show that partially Compensation and Occupational Safety and Health (K3) have a positive and significant effect on employee job statisfaction, while Work Motivation does not have a significant effect on employee job statisfaction at the CV. Rizky Berdikari Mandiri. However, the study also found that work motivation does not have a significant effect on employee job satisfaction at CV. Rizky Berdikari Mandiri. This finding suggests that while motivation is often seen as a driving factor for employee performance, other factors, such as compensation and workplace safety, may have a more direct and immediate influence on job satisfaction in this particular context. It is possible that the intrinsic and extrinsic motivators currently in place at the company may not be as effective or prominent in comparison to compensation and safety initiatives. The study concludes that while compensation and occupational safety are significant drivers of job satisfaction, work motivation should still be addressed but perhaps with more targeted strategies to ensure that employees are adequately motivated and engaged. Further research could explore how different types of motivation—intrinsic and extrinsic—affect employee satisfaction in various organizational settings.

This study examines the role of organizational citizenship behavior (OCB) as a moderator in the relationship between employee engagement, job satisfaction, and employee performance at the Tarokan District Office in Kediri Regency. The research focuses on analyzing how these variables interact and influence each other within the organizational context. The findings indicate that employee engagement has a significant impact on employee performance. This suggests that when employees are more engaged in their work, they tend to exhibit higher levels of performance. Similarly, job satisfaction also significantly influences employee performance. Employees who are satisfied with their work environment and tasks tend to perform better in their roles. However, the study reveals that organizational citizenship behavior does not significantly influence employee performance. This implies that while OCB is often considered a valuable aspect of employee behavior, it does not directly affect how well employees perform their tasks in this particular setting. Additionally, employee engagement does not significantly affect organizational citizenship behavior, indicating that engaged employees do not necessarily engage in extra-role behaviors like helping others or going beyond job requirements. The research also shows that job satisfaction does not have a significant effect on organizational citizenship behavior, which suggests that employees’ satisfaction with their work does not automatically lead to behaviors that contribute to the broader success of the organization. Furthermore, neither employee engagement nor job satisfaction significantly influences employee performance through organizational citizenship behavior, indicating that OCB does not serve as an effective moderator in these relationships. In conclusion, the main factor in improving employee performance is organizational citizenship behavior does not play a significant moderating role in this dynamic at the Tarokan District Office.

Background: Anemia is one of the public health problems commonly found among adolescent girls, especially in developing countries like Indonesia. This condition affects concentration, academic performance, and productivity, making early detection an essential step to prevent long-term complications. Objective: This study aims to determine the results of early detection of anemia based on clinical symptoms and hemoglobin (Hb) levels among adolescent girls at SMPN 18 Palembang. Methods: This research used a descriptive design with a cross-sectional approach. A total of 132 seventh-grade female students were selected randomly. Data were collected through an anemia symptom questionnaire and hemoglobin level measurement using a hemoglobinometer. Results: The study found that 23.5% of respondents were anemic (Hb < 12 g/dL), and 48.5% showed symptoms of anemia. However, the sensitivity of symptoms in detecting anemia was only 39%, specificity was 19%, with a positive predictive value (PPV) of 60.93% and a negative predictive value (NPV) of 8.82%. Conclusion: Based on the findings, symptom-based detection alone is not sufficiently accurate to diagnose anemia. Hemoglobin level examination is still required as a more valid and objective screening method for the early detection of anemia in adolescent girls In addition to medical intervention, the study advocates for increased awareness and education about anemia, its causes, and prevention methods among students, parents, and educators. Addressing nutritional deficiencies, especially iron intake, through dietary improvements and supplementation is essential in combating anemia in adolescent girls.

This study was conducted to examine the effectiveness of Kevlar as a structural material in Medium Altitude Long Endurance (MALE) Unmanned Aerial Vehicles (UAVs), particularly those designed with winglet innovations. In UAV development, material selection plays a crucial role since it directly affects flight performance, fuel efficiency, and the overall durability of the aircraft structure. Kevlar is widely recognized as a lightweight yet highly durable material, making it an interesting candidate to replace more conventional options such as aluminum and carbon fiber composites. Two approaches were applied in this research: numerical simulations using aerodynamic software and experimental testing on a prototype wing and winglet reinforced with Kevlar. The analysis focused on comparing lift, drag, total aircraft weight, and fuel consumption between Kevlar-based structures and conventional materials. The results demonstrate that Kevlar significantly improves aerodynamic efficiency and extends flight endurance due to its lower weight. Moreover, Kevlar exhibits superior resistance to dynamic loads and impacts, which are critical during certain flight conditions. However, challenges remain in terms of higher production costs and more complex manufacturing processes compared to traditional materials. Despite these limitations, the findings provide valuable insights for developing more efficient and durable MALE UAVs, while also encouraging innovation in aerodynamic design through the application of winglet technology.

This research aims to develop and evaluate the performance of a steam plant prototype designed as an alternative source of electrical energy to support the Vessel to Grid (V2G) concept. Utilization of backup energy on ships is becoming important as electricity demand increases and demands for a more sustainable electrical system. This system relies on ESP32 microcontroller technology as a control center that functions to monitor and control several key parameters, including steam pressure, combustion temperature, boiler water level, and the generated electrical voltage. The research method used is an experiment with a static and dynamic testing approach. Static testing is carried out to measure the performance of main components such as the boiler, turbine, and generator separately, while dynamic testing focuses on evaluating the overall system by involving the integration of sensors and supporting actuators. The test data is then analyzed quantitatively to determine the system's response to variations in steam pressure, temperature, and other operational conditions. The results show that the steam produced by the boiler is able to rotate the turbine, thereby driving the generator to produce electricity. The maximum voltage achieved is 25.7 volts at a steam pressure of 50 psi. The highest energy conversion efficiency was recorded at 4%, while the lowest efficiency was 0.9%. These findings demonstrate that, despite its relatively low efficiency, the prototype can function as an alternative energy source and emergency backup solution. Thus, this research provides an initial contribution to supporting the implementation of the V2G concept through the development of a small-scale steam plant-based energy conversion system.

Simultaneously, the three variables—ROE, Asset Structure, and CR—have a significant influence on Capital Structure. These findings can serve as a reference for corporate financial management in optimizing capital structure decisions.

This study is motivated by the importance of employee performance as a key factor in achieving organizational goals. Optimal performance is significantly influenced by various factors, one of which is workload and the working environment. An unbalanced workload can hinder productivity, while a non-conducive working environment can reduce comfort and work enthusiasm. Therefore, this study aims to analyze the impact of workload and the working environment on employee performance at PT Kampung Bali Indah Jakarta Pusat, both partially and simultaneously. This study uses a quantitative approach with a saturated sample of 52 respondents. Data collection was conducted using questionnaires, and the data were analyzed using SPSS version 25. The analysis included validity and reliability tests, classical assumption tests, multiple linear regression, t-tests, F-tests, and the coefficient of determination. The results show that workload has no significant partial effect on employee performance. This indicates that, although excessive workload can affect performance, other factors play a more dominant role in influencing employee performance. In contrast, the working environment has a positive and significant impact on employee performance. A conducive work environment provides comfort for employees to work more effectively and efficiently. Simultaneously, both workload and the working environment significantly affect employee performance, contributing 73.5%. This means that more than 70% of employee performance is influenced by these two factors, while the remaining performance is influenced by other factors not covered in this study. These findings suggest that to improve employee performance, the company should enhance the working environment to better support employee comfort and productivity. On the other hand, workload management should also be adjusted to remain optimal without adding excessive pressure on employees.

Traditional markets play a central role in the local economic system and the social life of communities, particularly in Medan City. However, the dynamics of urbanization, competition from modern retail, and changes in consumer behavior have posed significant challenges to their sustainability.

Concrete roof tiles are an important material in building construction, particularly for roofing work, due to their advantages in terms of strength, durability, and material availability. This study aims to analyze two main physical characteristics of concrete roof tiles, namely bending load and water absorption, using a literature review approach from various previous studies. Bending load refers to the material's ability to withstand bending forces, while water absorption describes the material's capacity to absorb and store water through its pores. These two properties significantly influence the quality and durability of roof tiles in facing external environmental conditions, especially wet-dry cycles and mechanical loads. The results of the literature review indicate that the use of waste as an aggregate substitute in concrete mixes can significantly improve the performance of concrete roof tiles. For example, research using broken roof tiles and ceramic waste as aggregate substitutes successfully increased flexural strength to a range of 12.5–15.0 MPa. Meanwhile, variations in water absorption were recorded in the range of 4%–8%, depending on the material composition and production method. This proves that the use of recycled materials not only supports sustainability but also improves the mechanical and physical properties of concrete roof tiles. Overall, this study underscores the importance of material innovation in concrete roof tile production, particularly utilizing waste as an alternative aggregate. However, further research is needed to explore the best combination of materials and production techniques for producing high-quality, efficient, and environmentally friendly concrete roof tiles.
