Abstract

The integration of heat pipe technology into Solar Photovoltaic/Thermal (PV/T) systems presents a significant advancement for enhancing overall energy conversion efficiency by simultaneously generating electricity and recovering thermal energy. This review paper systematically examines the design, operational principles, performance, and future outlook of heat pipe-integrated PV/T systems. Heat pipes, as highly efficient passive two-phase heat transfer devices, effectively mitigate the critical issue of efficiency loss in PV modules caused by elevated operating temperatures. By utilizing internal evaporation-condensation cycles, they rapidly extract waste heat from PV cells, thereby lowering cell temperature, increasing electrical output, and enabling the recovery of useful thermal energy for applications such as water and space heating. The review categorizes and analyzes various heat pipe configurations, including conventional designs, Loop Heat Pipes (LHPs), and Pulsating Heat Pipes (PHPs), highlighting their respective advantages in terms of integration ease, long-distance heat transport, and high heat flux management. Despite their promising potential, key technological challenges such as thermal contact resistance, material compatibility, structural integrity, and economic viability are identified as barriers to widespread adoption. Future research directions emphasize the need for innovations in advanced materials (e.g., nanofluids), hybrid systems with Phase Change Materials (PCMs), optimized design through computational modeling, and the development of standardized testing protocols. Ultimately, heat pipe-integrated PV/T systems are poised to play a crucial role in the renewable energy transition, offering a compact, efficient, and sustainable solution for co-generation of electrical and thermal power.

Abstract

The low level of drinking water subscriptions at PDAM Tirta Sari in Binjai City is a problem that needs to be studied to determine the causal factors. This study aims to analyze the factors that most influence the low interest of the people of Binjai City in subscribing to PAM. The method used is a weighting and ranking analysis of several hypotheses related to tariffs, water quality, service continuity, network coverage, and the availability of alternative water sources. The results of the analysis indicate that the mismatch between PDAM Tirta Sari Binjai City's tariffs and the quality of services provided is the most dominant factor influencing the low level of subscriptions at PDAM Tirta Sari Binjai City. This factor is ranked first with the highest total value. Other factors that also influence are low water pressure, limited distribution network coverage, and the existence of alternative water sources, while the quality of PDAM Tirta Sari Binjai City's water sourced from the Bingai River Watershed (DAS) has the lowest influence compared to other factors.

Abstract

Advances in information technology have encouraged educational institutions to generate large amounts of student academic data, such as grades, attendance, and learning activities. However, in practice, this data is still mostly used for administrative purposes and has not been optimally utilized to improve the performance of the learning system. This study aims to analyze student academic performance patterns and optimize the performance of the academic data-based learning system at the senior high school (SMA) level from an industrial engineering perspective. This study uses a descriptive quantitative approach with a case study method at SMAS Al Azhar Medan. The research data consists of student academic data as secondary data and student perception data as primary data obtained through questionnaires. Data analysis techniques include descriptive statistical analysis, simple correlation analysis, and analysis of the gap between actual conditions and learning performance standards. The results show that attendance and assignment scores have a positive relationship with student learning outcomes. In addition, there is still a gap between actual learning performance and the ideal conditions set by the school. Based on these analysis results, this study produces recommendations for optimizing the learning system oriented towards process improvement and data-based learning decision making. This study is expected to be an initial reference in the development of an academic data-based learning system at the high school level.

Abstract

This research aims to develop a sustainable egg supply chain model through the application of Green Supply Chain Management (GSCM). The research method used is qualitative with a literature study approach, through analysis of various relevant national and international journals. The results of the study show that the main dimensions of GSCM that affect the sustainability of the egg supply chain include green purchasing, green manufacturing, green distribution, reverse logistics, and green collaboration. The application of this concept is able to reduce production waste, reduce carbon emissions, increase cost efficiency, and strengthen the competitiveness of egg products in the market. The resulting conceptual model describes a circular supply chain system, where waste and production by-products can be reused as new inputs in the production process. Thus, GSCM is not only oriented towards economic efficiency, but also supports environmental and social sustainability in an integrated manner. This study recommends the importance of collaboration between farmers, distributors, and the government in strengthening the implementation of green supply chains in the egg agribusiness sector.

Abstract

Road and drainage infrastructure development is an important component in supporting community mobility, economic growth, and environmental sustainability. Simalungun Regency as a region with extensive road network coverage still faces various problems, such as high levels of road damage and suboptimal drainage system function. This study aims to analyze the implementation of road and drainage infrastructure development carried out by the Simalungun Regency Public Works Department, by reviewing factors that influence the effectiveness of its implementation, the level of development integration, and the role of community participation based on the theory of Success Factors in Managing Wastewater Infrastructure through Community Participation . The research method used is a descriptive qualitative approach with data collection techniques through documentation studies, observations, and interviews. The results of the study indicate that the implementation of road and drainage infrastructure development has been carried out in accordance with regional planning, but its effectiveness has not been optimal. Budget limitations, human resource capacity, weak supervision, and low community participation are the main factors inhibiting the success of development. In addition, the integration between road development and the drainage system is still low, thus affecting the sustainability of infrastructure. Therefore, it is necessary to strengthen integrated development governance, increase community participation, and optimize supervision and funding so that road and drainage infrastructure development can be sustainable and provide long-term benefits for the people of Simalungun Regency.
