Abstract

Critical thinking skills are students' cognitive processes in which they systematically and accurately analyze the problems they face, carefully and thoroughly differentiate these problems, and identify and analyze information to develop problem-solving strategies. The purpose of this research is to describe the critical thinking of high school students in Newton's law material. However, the results obtained reflect the thinking skills of Indonesian students from top to bottom. From the results of this study, it was concluded that students' weak high-level reasoning abilities indicated that many students made mistakes when solving routine problems in familiar contexts. Data was collected in the form of a multiple choice test in which there were 5 questions provided. The technique used in analyzing the data is to observe students answering questions. From the tests that have been carried out, the results are obtained in terms of the percentage of students' understanding, namely 15% have a good level of understanding, 65% have a fairly good understanding, and 25% have a bad understanding. The conclusion is the ability to think critically and understand physics concepts which are part of Newton's Laws. Students have not been able to think critically on Newton's law questions, namely on calculation questions. Meanwhile, students can still work on questions regarding the concepts of Newton's law.

Abstract

Osteoporosis merupakan suatu kondisi penurunan kesehatan tulang para lansia yang disebabkan faktor predisposisi terjadinya fraktur. Hal ini merupakan konsekuensi dari adanya proses penuaan, terutama bagi wanita. Sebanyak 1,5 juta kejadian fraktur terjadi di United States setiap tahunnya. Populasi lansia di Indonesia cukup besar, di mana pada tahun 2013 populasi penduduk Indonesia yang berusia 50 tahun ke atas sebanyak 19% dari 251 juta penduduk. Berdasarkan tabel di atas dapat diketahui bahwa persentase responden wanita yang mengalami menopause terpapar sinar UV lebih tinggi (87,5%) dibandingkan dengan wanita menopause yang tidak terpapar sinar UV yaitu 12,5%. Dari data yang di atas juga dapat diketahui bahwa wanita yang tidak menopause terkena paparan sinar UV lebih tinggi (92,5%) dibandingkan dengan wanita tidak menopause yang tidak terkena paparan sinar UV yaitu 7,5%. Dari hasil penelitian yang didapatkan, ditarik kesimpulan bahwa responden wanita menopause yang sering terkena paparan sinar UV lebih banyak daripada yang tidak terkena paparan sinar UV begitu juga pada responden wanita yang tidak menopause. Hal ini disebabkan oleh tingginya kesadaran wanita menopause dan wanita tidak menopause terhadap besarnya manfaat sinar UV bagi kesehatan tubuh terutama kesehatan tulang.
