Meningkatkan Kekuatan Penyelidikan: Memahami Resistivitas di Kelas Fisika: Penerapan Hukum Ohm dalam Pembelajaran Berbasis Kelas
No full textAbstracts This study aims to explore the effectiveness of inquiry-based learning in improving students’ conceptual understanding of electrical resistivity within the context of physics education. Many students struggle to comprehend the relationship between resistance, length, and cross-sectional area of conductors, often due to abstract instruction and a lack of hands-on experience. To address this, a classroom-based experimental activity was designed where students investigated resistivity using Ohm’s Law and direct measurements of voltage and current. The participants, consisting of tenth-grade science students, conducted experiments using wires of varying dimensions and calculated resistivity values. Pretest and posttest assessments were administered to evaluate conceptual gains, and the results showed a moderate to high increase in understanding based on normalized gain (N-gain) scores. The findings highlight that inquiry-based methods enable students to engage in authentic scientific practices such as observation, data collection, and analysis. The novelty of this study lies in its integration of low-cost, accessible experiments into structured inquiry learning, proving that conceptual depth can be achieved without sophisticated equipment. The results suggest that applying inquiry-based strategies in physics classrooms can enhance students’ scientific literacy, problem-solving abilities, and critical thinking, contributing to meaningful and effective science education.Penelitian ini bertujuan untuk mengeksplorasi efektivitas pembelajaran berbasis penyelidikan dalam meningkatkan pemahaman konseptual siswa tentang resistivitas listrik dalam konteks pendidikan fisika.

Exploration of Smoking Behavior of Adolescent Girls in Makassar City
Get PDFSmoking behavior among adolescent girls is increasingly observed in many large cities, including Makassar City. The background of this study is to understand the factors that influence smoking behavior among adolescent girls, who often experience distinct social and psychological dynamics compared to other adolescent groups. This study aims to explore the motivations, social environmental influences, and perceived health risks related to smoking behavior among adolescent girls in Makassar City. This study used a qualitative approach with in-depth interviews with 10 adolescent girls who smoke, selected by purposive sampling from various high schools in Makassar. Data analysis was conducted thematically to identify patterns and main themes that emerged from the interviews. The results showed that environmental factors, such as peer influence and social media, as well as social pressure to look “mature” are the main triggers of smoking behavior in adolescent girls. In addition, a low understanding of the long-term health risks also contributes to their decision to smoke. However, some adolescents showed awareness of the dangers of smoking, although not strong enough to kick the habit. The conclusion of this study is that more comprehensive interventions are needed, focusing on health education aimed specifically at adolescent girls, as well as controlling social influences that encourage smoking behavior

Enhancing Childbirth Preparedness: The Effects of Prenatal Yoga on Physical nnd Mental Readiness
No full textChildbirth requires both physical and mental readiness, yet many women face it with anxiety and insufficient preparation. Prenatal Yoga is increasingly recognized as a holistic intervention that integrates physical, psychological, and emotional preparation. This study aimed to examine the effect of Prenatal Yoga on the physical and mental readiness of pregnant women in facing childbirth. A cross-sectional quantitative study was conducted in May 2025 involving 54 pregnant women in Blora Regency. Data were collected using structured questionnaires to assess physical readiness (body flexibility and discomfort) and mental readiness (anxiety and relaxation) through the Hamilton Anxiety Rating Scale (HARS). The association between Prenatal Yoga and readiness was analyzed using Chi-Square and Fisher’s Exact tests. The study found no significant association between socio-demographic factors or yoga practice and physical readiness. In contrast, mental readiness was significantly associated with place of residence (p = 0.006), maternal education (p = 0.025), and participation in prenatal yoga (p = 0.000). Prenatal Yoga emerged as the strongest predictor of mental readiness for childbirth, highlighting its potential as a safe, accessible, and effective strategy to reduce anxiety, enhance self-efficacy, and improve emotional resilience. Promoting Prenatal Yoga within maternal health programs may empower women to face childbirth with greater confidence and mental preparedness
Determinants of Work Fatigue in Damri Bus Drivers in The Jakarta Metropolitan Area (Jabodetabek)
Get PDFBus drivers are among the occupational groups at high risk of experiencing work-related fatigue, which is a major contributing factor to traffic accidents. This study aims to identify factors associated with work fatigue among urban Damri bus drivers in the Jabodetabek area. A cross-sectional design was used in this study. This study included 98 drivers who met the eligibility criteria. There were two factors that caused fatigue examined in this study, namely internal factors (age, marital status, education level, smoking habits, nutritional status, alcohol consumption, caffeine consumption, and sleep quality) and external factors (mental workload, length of service, working hours, and work stress). Data were collected using standardized instruments: the Swedish Occupational Fatigue Inventory (SOFI) to measure fatigue levels, the Perceived Stress Scale-10 (PSS-10) for work stress, NASA-TLX for mental workload, and the Pittsburgh Sleep Quality Index (PSQI) for sleep quality. Bivariate analysis was conducted using the chi-square test. The results showed that 45.9% of respondents experienced moderate levels of work fatigue. Caffeine consumption (p=0.042) and work stress (p=0.001) were significantly associated with work fatigue. Meanwhile, factors such as age, marital status, education level, nutritional status, alcohol consumption, smoking habits, sleep quality, mental workload, working hours, and years of service were not significantly associated. Caffeine consumption and work stress were key contributors to work fatigue among drivers, while other factors showed no significant association. It is recommended that the company implement stress management programs and regulate caffeine consumption among drivers
