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.

Efforts to sustainably improve the resistance, growth and yield of soybean plants can be carried out through the use of elicitors. This study aimed to determine the effect of various types of elicitors and their interactions on two soybean varieties, as well as to identify the most elicitor type for enhancing the growth and yield of soybean plants. The experiment was conducted from May to July 2025 in Iloheluma Village, Tilongkabila Subdistrict, Bone Bolango Regency, Gorontalo Province. A Split Plot Design was employed with elicitor types as the main plots : E0 (no elicitor), E1 (Siam weed, Billygoat-weed, Stonebreaker, Indian copperleaf, and White leadtree), and E2 (Devil’s horsewhip leaf, Gliricidia leaf, Green chiretta, Guava leaf, and Senna tora). Soybean varieties Dega 1 (V1) and Grobogan (V2) were assigned as subplots. The results showed that elicitor types had a significant effect on the growth and yield of soybean plants, as indicated by plant height at 28 days after planting (DAP), number of leaves, 100-seed weight, and dry shelled yield per plot. In contrast, varietal treatments had no significant effect on soybean growth and yield. Moreover, there was no ineraction between elicitor types and soybean varieties across all observed parameters. The best elicitor 2 for supporting soybean growth and yield was Elicitor 2, consisting of Devil’s horsewhip leaf, Gliricidia leaf, Green chiretta, Guava leaf, and Senna tora.

Based on the Decree (SK) on the Change of Slum Locations in Bone Bolango Regency, Dutohe Village in Kabila District was designated as one of the areas experiencing a decline in residential quality and classified as a light slum area. The existing condition shows that the average damage level of neighborhood roads reaches 40.03%, and the drainage system is not yet optimal with an average value of 33.19%. This study aims to plan infrastructure improvements in the slum settlement area of Dutohe Village and to estimate the cost of planning road and drainage infrastructure as an effort to create a more livable and sustainable settlement area. The research method used is a mixed method, combining quantitative and qualitative approaches through field surveys, interviews, and technical design analysis (Detail Engineering Design). The research results indicate that the proposed technical plan includes the construction of neighborhood roads using paving blocks with a total length of 3,038 meters and drainage channels using U-Ditch and stone masonry with a total length of 3,994 meters. The total estimated cost required is IDR 3,671,111,028.53, consisting of 84.93% for road works and 15.07% for drainage works. The project implementation period is planned for approximately five months (155 days) based on the network planning analysis. The improvement of road and drainage infrastructure is a top priority to reduce slum conditions in Dutohe Village. It is recommended that the local government allocate budgets gradually and involve community participation to ensure sustainable settlement management and improve residents’ quality of life.

Analisis Variasi Abu Batu sebagai Substitusi Parsial Agregat Halus Terhadap Kuat Tekan Beton Self Compacting Concrete (SCC)

2026-02-06T08:32:11+00:00

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.

Analisis Penempatan Tangga terhadap Simpangan akibat Beban Gempa dengan Metode Time History Analysis (Studi Kasus: Gedung Rawat Inap RSUD dr. Hasri Ainun Habibie)

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).
