The transition from secondary school to higher education represents a critical phase that requires academic, psychological, and social adaptation, particularly in laboratory-based programs such as Medical Laboratory Technology (MLT). First-year students encounter significant changes in learning systems, increased demands for independence, and laboratory practices that emphasize precision and professional responsibility. This study aims to analyze the learning enthusiasm, motivation, and learning readiness of first-year MLT students during their transition to university. A qualitative approach with a phenomenological strategy was employed to explore students’ lived experiences through in-depth interviews, observations, and documentation. The findings reveal that students’ experiences are characterized by initial shock toward the university learning system, laboratory practice as both a trigger of enthusiasm and a source of pressure, fluctuating motivation influenced by perceived self-competence, the central role of self-regulated learning in readiness, and social support as a buffering factor in adaptation. Laboratory sessions emerged as a key space for shaping academic and professional identity, while time management and collaborative learning strategies were crucial in sustaining engagement. These findings contribute to a deeper conceptual understanding of first-year transition dynamics in health education and provide practical implications for strengthening academic mentoring systems and fostering self-regulated learning skills among new university students.

I Made Karya Jurdiawan, Kasmat Saleh Nur , Sartika Dewi Usman — Fri, 27 Feb 2026 00:00:00 +0000

Self-Compacting Concrete (SCC) is designed to flow and consolidate under its own weight without mechanical vibration while maintaining high workability. The properties of SCC are strongly influenced by the characteristics of fine aggregate. Stone ash, which has fine particles and a rough surface texture, has the potential to be used as a partial replacement for fine aggregate. This study investigated the effect of stone ash substitution on the compressive strength and fresh properties of SCC in accordance with the European Federation of National Associations Representing for Concrete (EFNARC) 2005 criteria. Stone ash was substituted at 0%, 5%, 10%, 15%, and 20% of the fine aggregate content. Fresh concrete tests included slump flow, T₅₀₀, J-Ring, and GTM Screen Ability, while compressive strength was tested at 28 days. The results showed that all mixtures met the slump flow, viscosity, and GTM Screen Ability requirements. However, the 5% variation showed less satisfactory performance in the T₅₀₀ test, and the 5%, 10%, and 15% variations were classified as Category III (poor) in the J-Ring test. Compressive strength increased at 5%, 10%, and 15% substitutions to 36.66 MPa, 35.80 MPa, and 35.94 MPa, respectively, compared to 30.19 MPa for the control mix. The highest strength was achieved at 5% substitution, representing a 21.43% increase. At 20% substitution, compressive strength decreased to 34.25 MPa. These findings indicate that limited stone ash substitution can enhance SCC compressive strength while maintaining acceptable fresh concrete performance.

Indonesia has a high level of earthquake vulnerability due to its location within the Ring of Fire and at the convergence of three major tectonic plates. This condition necessitates the design of earthquake-resistant multistory buildings by considering stair elements that are integrated with the main structural system. Improper stair placement may affect structural stiffness and eccentricity and increase interstory drift, potentially leading to severe damage. This study analyzes the effect of stair position on the drift of reinforced concrete building structures using 3D modeling of three stair placement configurations from previous studies. Seismic load analysis employed the Time History Analysis method using three pairs of global earthquake records: Chi-Chi, Kobe, and El Centro. The analysis focused on evaluating interstory drift values to determine whether the stair placement configurations met safety standards. The findings indicate that stair placement significantly affects interstory drift. The Chi-Chi earthquake produced the largest interstory drift in Placement 3, particularly on the second and third floors, exceeding the allowable limit of 40 mm with values of 59.20 mm (X- direction) and 46.19 mm (Y-direction). This was followed by the El Centro earthquake, whereas the Kobe earthquake resulted in the smallest interstory drift for the same configuration, remaining below the allowable limit, with values of 27.54 mm (X-direction) and 24.15 mm (Y-direction).

Analisis Kuat Tekan dan Workability Beton dengan Penambahan Silica Fume dan Variasi Tras Lompotoo Sebagai Substitusi Parsial Agregat Halus

Rayhan Putri Maiyo, Kasmat Saleh Nur, Komang Arya Utama — Mon, 30 Mar 2026 00:00:00 +0000

The use of pozzolanic materials, such as silica fume and Lompotoo trass, aims to enhance concrete performance while reducing the use of sand as a fine aggregate. Lompotoo trass is a material with a high fineness, making it suitable for partial substitution for fine aggregate. This study aims to analyze the effect of adding silica fume and varying the percentage of Lompotoo trass as a partial substitution for fine aggregate on the compressive strength and workability of concrete. The testing was conducted by producing four mix variations: normal concrete and concrete with partial substitution of Lompotoo trass for fine aggregate at 25%, 50%, and 75%. Each variation of Lompotoo trass substitution was combined with the addition of 10% silica fume. In general, changes in concrete characteristics were observed across all mix variations. The slump value showed a decreasing trend as the percentage of Lompotoo trass substitution increased. On the other hand, the compressive strength of normal concrete of f’c 30.34 MPa increased to f’c 32.16 MPa at 25% trass substitution, f’c 32.97 MPa at 50% substitution, and reached f’c 36.65 MPa at 75% substitution. These results indicate that the use of Lompotoo trass combined with silica fume enhances the compressive strength of concrete, although it is accompanied by a reduction in workability.

The increase in the number of students and academic activities at the Faculty of Law, Gorontalo State University (UNG) has not been matched by the availability of adequate facilities and infrastructure. The existing buildings are limited in terms of space capacity, thermal comfort, and learning environment quality, resulting in a less than optimal learning process. In addition, the existing buildings are not fully adapted to the tropical climate, which is characterized by high temperatures, high humidity, and high rainfall throughout the year. Therefore, it is necessary to redesign the Gorontalo State University Faculty of Law building in a way that addresses these issues in a functional and sustainable manner. This design aims to formulate a design concept for the UNG Faculty of Law using a Tropical Architecture approach that is responsive to the climate and capable of improving thermal comfort, energy efficiency, and the quality of learning spaces. The methods used in the design include field observations, literature studies, comparative studies, and analysis of site data, space requirements, structure, and building utilities. The design results emphasize the processing of building mass orientation, optimization of cross ventilation and natural lighting, use of secondary skin elements, application of voids as vertical ventilation, and provision of green open spaces as microclimate controllers. The application of this Tropical Architecture approach is expected to produce a comfortable, functional, energy-efficient, and sustainable Faculty of Law building that supports academic activities at Gorontalo State University.

Analisis Dinamik Model Penularan Kolera dengan Mempertimbangkan Risiko Individu dan Intervensi Karantina

This study develops an SIQRB mathematical model to analyze the transmission dynamics of cholera by incorporating individual risk stratification and quarantine interventions. The model consists of six human compartments, including high- and low-risk susceptible individuals, infected individuals from each risk group, quarantined individuals, and recovered individuals, along with one environmental compartment representing the concentration of Vibrio cholerae. This framework allows a comprehensive analysis of the interaction between human populations and environmental factors in disease transmission. The stability analysis shows that the disease-free equilibrium is locally asymptotically stable when the basic reproduction number (R₀) is less than one (R₀ < 1), and becomes unstable when R₀ exceeds one (R₀ > 1), indicating the potential for endemic conditions. Sensitivity analysis identifies the most influential parameters affecting R₀, namely the immigration rate (Λ), the environmental transmission rate (βb), and the bacterial shedding rate (ξ). These parameters significantly contribute to the increase in disease transmission. Numerical simulations confirm the analytical findings, showing that higher values of these parameters lead to increased numbers of infected individuals and higher environmental bacterial concentrations. Conversely, environmental-based control strategies—such as mobility restrictions, improved sanitation, and water disinfection—are effective in reducing R₀ below one. Therefore, this study highlights the critical importance of environmental interventions in controlling cholera transmission and preventing long-term endemicity.
