Abstract

Rokok dapat menyebabkan berbagai penyakit, seperti peningkatan resiko kanker, penyakit pernapasan, efek kardiovaskular serta penurunan massa tulang. Perokok lebih cenderung mengalami kehilangan kepadatan tulang, dan lebih mudah mengalami patah tulang.Tujuan penelitian untuk mengetahui hubungan antara derajat perilaku merokok dengan indeks Bone Mineral Density(BMD) di Rumah Sakit Murni Teguh Medan. Jenis penelitian ini merupakan penelitian kuantitatif yang sifatnya korelasional. Sampel dalam penelitian ini adalah 34 orang pasien yang berkunjung kePoliklinik Ortopedi Rumah Sakit Murni Teguh dengan criteria inklusi pria dan wanita perokok dan melakukan pemeriksaan BMD. Pengumpulan data menggunakan data primer dengan menggunakan kuesioner berdasarkan Indeks Brinkman dan data sekunde rberupa nilai indeks BMD dari rekam medis. Hasil penelitian diketahui pasien dengan kategori perokok berat. Indeks BMD pasien lebih banyak berada pada kategori osteopenia sebesar 64,7%. Analisa data menggunakan uji korelasi spearman diperoleh nilai p < 0,004 (p < 0,05) dengan nilai r sebesar -0,483.

Abstract

This study investigates the effectiveness of Android-assisted virtual physics learning developed using Smart Application Creator in enhancing students' critical thinking skills during the study of optical material in high school. The novelty of this research lies in its integration of mobile-based virtual learning environments with a targeted emphasis on Higher Order Thinking Skills (HOTS) a crucial competency in 21st-century education. While prior studies have explored virtual learning media in science education, few have systematically examined their cognitive impact particularly on critical thinking in the context of physics. A quasi-experimental design with a nonequivalent control group was used, and purposive sampling determined the participant pool. Data were collected using validated test instruments designed to assess five core indicators of critical thinking. Statistical analysis through an independent sample t-test at a significance level of α = 0.05 revealed a sig. (2-tailed) value of 0.00, indicating a significant difference between the experimental and control groups. The average N-Gain in the experimental group (0.74) significantly outperformed that of the control group (0.53). The most notable improvements in the experimental group included the ability to evaluate arguments (88.2%), draw conclusions (84.3%), identify assumptions (80.4%), apply deductive reasoning (75.2%), and logically interpret data (65%). These findings demonstrate the pedagogical potential of Android-based virtual media in supporting cognitive development in physics learning. The study provides a foundation for developing scalable, interactive learning tools that align with HOTS frameworks, offering new directions for physics instruction in digitally driven classrooms.

Abstract

The aim of the research is to explore the cognitive profiles patterns of strengths and weaknesses of children with specific learning difficulties and to assess how these profiles can inform individualized educational interventions. Using a collective case study approach, data were collected from four school-aged children (7–9 years old) with low academic performance through a mixed-method design involving parental interviews and comprehensive psychological testing. The Wechsler Intelligence Scale for Children-Revised (WISC-R) and the Marianne Frostig Developmental Test of Visual Perception were employed to assess intellectual ability, working memory, attention, and visual perception. Results revealed that all participants had average to very superior intellectual capacities, indicating that learning difficulties were not related to intelligence level. However, consistent patterns of weaknesses were identified in working memory, attention, and visual-motor coordination, while abstract verbal reasoning remained a cognitive strength. One participant exhibited a unique strength in perceptual organization, linked to enriched sensory interaction and high intellectual capacity. This research offers a novel perspective on recognizing specific learning difficulties through cognitive profiling rather than general academic performance. The findings underscore the importance of comprehensive assessments in identifying hidden handicaps and developing tailored educational strategies. The implication is clear: effective interventions must consider both cognitive strengths and weaknesses to support academic achievement and emotional well-being in children with specific learning difficulties.
