Abstract

This study investigates the effectiveness of the PQRST (Preview, Question, Read, Summarize, Test) model in enhancing scientific literacy and critical thinking skills among eleventh-grade students at SMAN 3 Kota Cirebon, particularly focusing on the human excretory system in the context of the Merdeka Curriculum. The research applied a quasi-experimental design with a pretest-posttest control group approach, involving 30 students from two classes. The experimental group received instruction using the PQRST model, while the control group followed conventional teaching methods. Results indicate significant improvements in the experimental group's scientific literacy across three aspects: context, knowledge, and competence. The normalized gain (N-Gain) scores were higher in the experimental group (0.72 for context, 0.77 for knowledge, and 0.71 for competence) compared to the control group. Statistical analysis revealed significant differences (p < 0.05) in all aspects of scientific literacy, confirming that the PQRST model significantly enhanced students' learning outcomes. Moreover, students reported positive responses towards the PQRST model, citing improved engagement, confidence, and critical thinking abilities. This study supports the goals of the Merdeka Curriculum in fostering independent, critical thinkers with strong scientific literacy. In conclusion, the PQRST model has proven to be an effective learning strategy to improve scientific literacy, critical thinking, and student engagement, which aligns with the objectives of the Merdeka Curriculum to produce globally competitive, literate students.

Abstract

Bone fractures are rising worldwide due to aging populations and increased trauma, creating demand for implants that overcome infection, delayed healing, and poor osteointegration. Multifunctional biomaterials, especially PLA–HA Bioxcrew systems, offer integrated mechanical support with antibacterial, anti-inflammatory, and osteogenic functions while remaining biocompatible. Implant-associated infections driven by Staphylococcus aureus and Gram-negative bacteria persist because of biofilm formation and chronic inflammation. Bioxcrew advancements address these barriers through metal-ion doping, nanoscale surface engineering, and incorporation of antimicrobial agents into biodegradable polymer matrices, enabling controlled ion release, immune modulation, stem-cell recruitment, and improved bone regeneration. Stainless steel provides strength, hydroxyapatite enhances biological integration, and PLA enables safe degradation and localized drug delivery, making their hybridization ideal for next-generation implants. Using a narrative–integrative review of peer-reviewed literature from 2018 to 2025, this study synthesizes trends in antibacterial strategies and regenerative performance. Findings show that hybrid Bioxcrew platforms significantly reduce infection risk and enhance functional bone healing.
