Abstract

This study aims to explore high school students' understanding of Newton's laws of motion. The research method used is qualitative descriptive, with data collection through a two-tier diagnostic test. The instrument not only measures correct answers but also explores the reasons behind students' choices. Data analysis was conducted by dividing students' understanding into four categories: (1) Understanding the concept; (2) Misconception; (3) Not understanding the concept; and (4) Guessing. The results showed that students understood the concept of changes in velocity due to changes in the direction of force, with 56.2% of students understanding the concept. The largest misconception was found in the subtopic of Newton's Third Law, which reached 68.5%. Meanwhile, the percentage of students who did not understand the concept was lower than that of students who had misconceptions in all subtopics. These findings confirm that the majority of students did not understand the concept, but had initial understandings that were unscientific or inappropriate. Therefore, teachers need to prepare learning strategies that are not only informative but also reinforce concepts.

Abstract

According to the World Health Organization (WHO), the number of dysmenorrhea cases in 2020 was 1,769,425 individuals, with 90% being female. The prevalence of dysmenorrhea in Indonesia is 54.89% for primary dysmenorrhea and 9.36% for secondary dysmenorrhea. In DKI Jakarta, the prevalence of primary dysmenorrhea is 87.5%. Menstrual pain, also known as dysmenorrhea, occurs due to dysrhythmic contractions of the myometrium. The pain often interferes with daily activities, making its impact on adolescent girls particularly significant. The aim of this study is to determine the effect of green coconut water and effleurage massage on reducing the intensity of primary dysmenorrhea pain in adolescent girls at Dewi Medika Primary Clinic in 2025. This research uses a qualitative method with a case study approach. The sample consisted of two respondents experiencing primary dysmenorrhea, comparing one who received green coconut water and the other who received effleurage massage. The study was conducted in February 2025. The results showed a reduction in pain intensity in adolescents who experienced primary dysmenorrhea after receiving either green coconut water or effleurage massage. The decrease in pain intensity was more effective and occurred more quickly in the adolescent who received the effleurage massage compared to the one who received green coconut water.
