Abstract

The gas turbine is one of the most widely used equipment in oil and gas industries as an electric generator driving system. To maintain the reliability and performance of the gas turbine, a major inspection program is required. Thermal efficiency analysis is the parameters of success in major inspection activities. Thermal efficiency analysis is carried out by comparing data and operating parameters of gas turbine before and after the major inspection. The analysis aims to determine the actual efficiency of each component, and also the actual overall efficiency in the gas turbine. The study result is the actual thermal efficiency of a gas turbine after a major inspection has increased from 12.20% to 12.84% at a load of 6 MW, an increase from 15.76% to 16.77% at a load of 9 MW, and an increase of 18.59% to 20.16% at a load of 12 MW. Based on the actual performance comparison data with design data, it is known that the overall actual performance is still below the design performance, both heat efficiency, heat consumption and heat rate. This is caused by the operating lifetime

Abstract

Background: Pneumonia is a respiratory infection that can be life-threatening if not properly diagnosed and treated. The diagnosis of pneumonia currently relies on the expertise of pulmonologists to evaluate chest X-ray results. Therefore, there is a need for technology that can assist doctors in analyzing X-ray images quickly and accurately. Methods: This study employs Convolutional Neural Networks (CNN) to classify chest X-ray images into three classes: Normal, Mild Pneumonia, and Severe Pneumonia. Several experiments were conducted by varying the number of epochs, dataset size, image resolution, and the number of hidden layers to achieve accurate identification results. Results: The final testing results showed that using 15 epochs, 5 hidden layers, and a dataset of 5700 images for classification with CNN can achieve a training accuracy of 92.48% and a validation accuracy of 91%. Results from 50 chest X-ray images indicated identical identification accuracy between the readings by doctors and the proposed method, with doctors taking 15 minutes to read and the proposed method taking only 0.2 seconds with an identification accuracy of 100%. Conclusion: This study demonstrates that the proposed method can assist pulmonologists in diagnosing pneumonia with high diagnostic accuracy and short diagnosis time, thereby helping to improve the quality of healthcare services. Recommendations: This study recommends the use of CNN as a method for diagnosing pneumonia in chest X-ray images.

Abstract

This research explores the relationship between transformational leadership and job satisfaction in the creative industry in Asia, which is known for its unique dynamics and challenges. In this context, transformational leadership, characterized by the leader's ability to inspire, motivate, and empower employees, is viewed as a key factor in enhancing job satisfaction. This research aims to understand how elements of transformational leadership, such as a clear vision, effective communication, and attention to individual needs, can contribute to employees' feelings of satisfaction and engagement in their work. The research methods used include surveys and in-depth interviews with employees and leaders from various creative sectors, including art, media, and design. The collected data were analyzed to identify significant patterns and relationships between leadership practices and job satisfaction levels. The research results show that leaders who implement transformational leadership strategies not only succeed in creating a work environment that supports innovation and creativity but also enhance employee motivation and commitment. Most respondents reported that they felt more engaged and satisfied when working under leaders who adopted this approach. These findings provide valuable insights for organizations in designing effective leadership strategies in the creative sector, as well as highlighting the importance of paying attention to individual needs in the effort to achieve organizational goals. Thus, this research not only contributes to the academic literature on leadership and job satisfaction but also provides practical guidance for leaders and managers in enhancing job satisfaction in dynamic and creative environments. The recommendations generated from this research can help organizations in building a positive and productive work culture, thereby contributing to long-term success in the creative industry.

Abstract

In the continuously evolving digital era, the challenge of enhancing student engagement in the teaching and learning process is becoming increasingly complex. This research aims to explore and analyze the strategic application of emotional and spiritual intelligence as tools to enhance student engagement. Emotional intelligence, which includes the ability to recognize, understand, and manage emotions, plays a crucial role in building positive relationships between students and educators. On the other hand, spiritual intelligence allows students to find meaning and purpose in learning, which can enhance their intrinsic motivation. This study uses a qualitative approach by collecting data through surveys, in-depth interviews, and case study analyses in various educational institutions. The research results indicate that the integration of emotional and spiritual intelligence in teaching methods can create a more inclusive, supportive, and responsive learning environment. Students who are emotionally and spiritually engaged show increased academic involvement, better learning outcomes, and higher psychological well-being. Thus, this research recommends that educators adopt strategies that integrate both types of intelligence into their curriculum and teaching practices. These findings are expected to provide insights and guidance for educators to create more meaningful and effective learning experiences in the digital era, as well as to prepare students for future challenges.
