Abstract

The operational efficiency of mid-capacity (140 MW) Combined Cycle Gas and Steam Power Plants (CCGT) remains underexplored concerning the DIN-VDI 4661 standard, which defines key quality metrics for energy systems. Addressing this gap is crucial for establishing standardized benchmarks to optimize performance and reduce energy losses. Existing studies mainly focus on Combined Cycle Gas Turbine (CCGT) units outside the 100–180 MW range and often do not explicitly follow DIN-VDI 4661, limiting efficiency comparisons and hindering targeted optimizations. This study simulates a 140 MW CCGT using Ebsilon® Professional software, incorporating DIN-VDI 4661 guidelines to assess eight quality indicators, including thermal efficiency, fuel utilization, and power-to-heat ratio. The model integrates gas and steam turbines, heat recovery, and auxiliary components, with input parameters validated against industry data. Energy balance analysis and sensitivity tests identified loss points. Results show a gas turbine thermal efficiency of 31.39%, steam turbine efficiency of 39.59%, and total system efficiency of 48.42%. However, significant energy losses (52% of input energy) were observed, mainly in gas turbines (87,000 kW) and steam turbines (56,000 kW). These findings highlight the need for design optimizations, such as improving heat recovery and turbine efficiency, to meet DIN-VDI 4661 benchmarks.

Abstract

Access to clean water is a fundamental necessity that underpins effective public health services and the operational efficiency of health facilities, including the Bonggo Health Center in Sarmi Regency. Recognizing the importance of reliable clean water access, a community assistance initiative was launched to establish a sustainable water installation system at the Bonggo Health Center. This initiative is crucial to enhancing the health center’s ability to deliver quality healthcare services, as safe, clean water is essential for various healthcare functions, from sanitation to patient care. The primary aim of the assistance program is to equip the Bonggo Health Center with a dependable source of clean water, ensuring it meets health and safety standards for use in medical services. To achieve this goal, the implementation method was carefully structured, involving several sequential steps. First, the service team conducted a comprehensive location survey to assess the water requirements and potential challenges. Following this, the team engaged in in-depth problem discussions, planning sessions, and preparatory work to lay the groundwork for the installation. The actual construction of the water installation was then carried out, followed by rigorous testing and evaluation to ensure functionality and quality. Through close collaboration with the Armopa Village community, the service team successfully completed a fully operational clean water installation. This unit now provides a reliable supply of high-quality water for the Bonggo Health Center, significantly improving the center’s capacity to serve the healthcare needs of the surrounding community. This installation not only meets immediate needs but also sets a foundation for sustained health service enhancements and community well-being in the region.

Abstract

Technical skills in lathe machine operation are highly demanded in the manufacturing industry, particularly in the production of machine components and other equipment. However, in Heram District, Jayapura City, access to technical training remains limited, resulting in low competitiveness among the local workforce. The lack of training facilities and qualified instructors has become a major obstacle in developing the skills of productive-age youth. Therefore, basic training in lathe machine operation serves as an important step in improving the quality of human resources, particularly for productive-age youth in Heram District, Jayapura City. The objective of this community service program is to equip productive-age youth in Heram District with fundamental skills in lathe machine operation, thereby enhancing their employment opportunities and economic independence. The methods implemented in this program include: identifying training participants who meet the productive-age criteria; providing training facilities and equipment, including lathe machines, safety gear, and training modules; coordinating with competent instructors in the field of machining; delivering the training through both theoretical and practical sessions with a composition of 30% theory and 70% practice; and conducting evaluations through theoretical and practical examinations to assess participants’ competencies after the training. Based on the post-training evaluation results, participants demonstrated a solid understanding of the basic concepts in theory, and most were able to perform basic turning operations accurately. The training was highly relevant to participants’ needs, and the majority expressed satisfaction with the program. The final evaluation concluded that, on average, participants achieved good to excellent scores, with high satisfaction ratings for material delivery, instructor preparedness, practical sessions, and the facilities provided.
