Abstract

The low cognitive skills and ethical understanding of students in utilizing AI technology are major challenges in higher education in the digital era. This community service aims to improve these aspects through a Participatory Action Research (PAR) approach based on collaborative project-based learning. The method consists of four stages: building collaborative relationships between students, lecturers, and the campus community; implementing real-case-based projects supported by intensive training on AI, ethics, and the preparation of Student Creativity Program Proposals (PKM); reflective analysis of student ideas; and proposal presentations for evaluation. The results show significant improvements in pre-test and post-test scores, both in cognitive aspects (15.52 to 20.52) and ethical understanding (15.52 to 19.31). The implication of this service is that collaborative project-based learning effectively builds students' cognitive and ethical competencies holistically and can be adopted as a learning model to prepare students for responsibly facing technological challenges.

Abstract

Indoor air quality plays a vital role in ensuring comfort and maintaining the health of users in enclosed sports facilities, such as indoor futsal courts. Proper air circulation significantly contributes to thermal comfort and reduces health risks associated with inadequate ventilation. However, this aspect is often neglected in the design of such buildings. This study aims to: (1) analyze the performance of air circulation in indoor futsal buildings, (2) assess indoor air quality, and (3) develop a design model that optimizes airflow using computational simulation. The research methodology included field surveys and direct measurements of building and ventilation opening dimensions, air velocity, temperature, and concentrations of CO and CO₂. Simulations were performed by adding new inlets and outlets equal in area to the existing ones but repositioned strategically—additional inlets were placed at 6.70 meters above the floor, and outlets were located 1 meter above the floor. The third simulation scenario showed a significant improvement in airflow speed at the central part of the building, ranging between 0.7 m/s and 1.5 m/s. By increasing the total inlet area to 271.32 m² and the total outlet area to 171.6 m², with incoming airflow speeds of 2.7 m/s, a more effective and evenly distributed indoor air circulation was achieved. These findings confirm that modifying the placement and sizing of natural ventilation elements can substantially enhance airflow performance in indoor futsal facilities. The proposed design model contributes meaningfully to architectural practices aimed at creating healthier sports facilities that effectively respond to passive ventilation requirements and may serve as a reference for the design of similar buildings in tropical climate regions.

Abstract

This study explores the promising potential of Candlenut Shell Aggregate (CSA) as a sustainable and innovative alternative for lightweight concrete production. Derived from Aleurites moluccanus, CSA is an agricultural by-product characterized by its low density, moderate abrasion resistance, and high water absorption make it suitable for non-structural applications like wall panels and flooring. However, integrating CSA into concrete mixes requires careful management of the water-cement (w/c) ratio which significantly affects compressive strength, density, and workability. Concrete mixes were prepared using the absolute volume method, with w/c ratios ranging from 0.65 to 0.30, to identify the optimal balance. The absolute volume principle was applied for all mix designs. Our results indicate that an optimal w/c ratio of 0.55 yields the most favorable balance, achieving the highest compressive strength of 14.3 MPa and a maximum density of approximately 1850 kg/m3. This specific ratio strikes an ideal equilibrium between adequate cement hydration and effective void minimization within the concrete matrix. Conversely, higher w/c ratios lead to increased porosity, diminishing both strength and density, while lower ratios impair workability, hindering compaction and hydration, ultimately degrading performance. These findings resonate strongly with existing prior research, further emphasizing the crucial need for pre-treatment of CSA, such as soaking or the strategic incorporation of admixtures, to effectively mitigate its inherent high absorption and enhance overall mix performance. In conclusion, this study robustly confirms the feasibility of utilizing CSA as a lightweight aggregate. This represents a significant step towards developing an eco-friendly solution that not only contributes to global sustainability goals by repurposing agricultural waste but also actively reduces reliance on conventional, resource-intensive aggregates. Future research should explore the long-term durability of CSA-based concrete and investigate advanced admixtures to further enhance its properties for broader applications.
